  1. The hot roller in the fuser unit of a Lexmark T652 failed. The coating came off. I replaced the hot roller and put the fuser unit back in. I am still getting a 81 Replace Maintenance Kit Now error message, despite resetting the counter. However, reports or log will print out perfectly in Diagnostics/Service mode. Does it mean I need to get a new fuser unit? Did I miss some steps? Or did the printer blacklisted the fuser unit? Or did the fuser unit blacklisted itself when it failed

  2. I have a cm6030 throwing off a 30.01.40 error message. I have replaced the scb, the cpb, and the formatter board. I have checked all connections, and have updated the firmware to the newest version. I have swapped the sodimms between the formatter and scb to see if it might be a memory issue, and still no good. The jumpers on the scb have been removed since the cables are white. With both jumpers off, it throws the error above, and sometimes throws a 30.01.44 error. I put the jumper back on the toy pins, and am able to at least print to the machine, just not scan. Do you have some thoughts or suggestions on what else might cause this, or suggestions on what else to try.

    Thanks in advance.

  6. Hello. I just purchased a used HP Color LaserJet CM2320fxi MFP from ebay and have been having some issues with it.

    In short, the unit reports false paper jams when attempting to print in duplex. I opened the back panel as instructed but see no jammed paper or anything else that might be causing a blockage in the paper path.

    Some helpful information:

    I noticed the rear door and duplex assembly doesn’t seem to be properly aligned and pulling the rear assembly along with the rear door takes some force, which seems a tad excessive.

    Any help would be greatly appreciated.

  8. I have a Lexmark t654. Recently the fuser, transer roller, etc were replaced as part of a maintenance kit service. Since replacement, everything prints great from the manual feeder or top tray. However, if printing from the bottom tray, the print on the left side of the page is lighter and faded. I have been unable to find any problem or explanation. Swapping trays makes no difference, as the problem stays with the lower paper path. I am at a loss! Anyone have any suggestions, ideas, or solutions?

    • Check your paper media type setting for your bottom tray. An incorrect paper type meant for Plain Paper but was set as Label might yield different print result. The toner might not be fusing properly with the paper type.

    • try the old transfer roller back in there. The new one might not be 100% level, slight bend in the shaft or the foam can cause the issue you are having. you can pop the transfer roller out, put it on a level table then roll it and see if you notice one side being higher than the other. that slight difference would cause the slightly lighter transfer/print you are seeing

  11. We have several Lexmark C734 printers. They are all about 2 years old now. Recently we have had 3 instances of the printer “flooding” entire pages with a single color. So far we have had one do blue pages, one yellow and one magenta!
    We fixed one with a complete rebuild and thought that the transfer module had been the culprit but another seems like it may be a bad toner cartridge. My logic suggests that it might be a bad connection to a phot conductor since swapping out photoconductors doesn’t fix the issue. The one that we currently have making blue pages will consistently do the following: after a power on reset, printing the menu settings report, we get three normal pages and the fourth page has a full Cyan background.
    I hope I am posting this in the right place…

  13. I have two lexmark printers a T650 and a T652 both having the same issue of very light print on the left side of the page and it gets slightly better going right. On both machines i have tried the following: 4 different toner cartridges both OEM and compatible from 2 different vendors, 3 new maintenance kits including stealing parts from another t652 that is working properly, cleaning the glass on the printhead (laser), swapping out the power supply and cleaning all contacts all to no avail. Only thing i haven’t tried is swapping out the high voltage board wondering if that might be worth a shot or if anyone else has seen this issue?

    Like

    • Voltage for the various parts of the toner cartridge comes from the High voltage power supply. Im not as familiar with this model as others but on a lot of Lexmarks the HVPS sits under the toner cartridge and is prone to toner getting on the board. Might cause a contact issue. In your situation the first thing I would have done is check the primary charge roller, part of PM kit. Just replaced one for this issue. Second would be transfer roller. You might want to make sure the transfer roller is spring loaded if a spring pops out they wont lift and make good contact with the drum. In other words get level and see if the transfer roller is uniform across the print cavity. Also make sure its spring loaded. If pressed down it should go down and bounce back. Same kind a goes for the primary charge roller make sure it goes down all the way and nothing is obstructing it from making contact with the drum surface. Last is the paper guide in the front of the machine. Between MP tray assembly and transfer area. Once again Im not as familiar with these than others but I’ve seen that front paper guide get knocked out of place or not correctly installed and it causes issues like this. I replaced a cart and a charge roller once time for similar issue only to find that front plastic piece wasn’t snapped in place. A five second fix resulted in a frustrating call. So for you I would maybe start looking for obstructions or possibly even bent contacts. I’ve seen bent contacts also cause this issue so you might take a good one and compare contact positions.

      • The first question is old so I’m not going to bother addressing it at such a late date. As to auto recovery. I have no idea why that fixed the problem. The setting is to reprint the previous page so you don’t loose it. If its turned off and you get a jam it doesn’t print the jammed pages. On, if it has sufficient memory it will attempt to reprint the lost pages. The paper bin full issue is a result of a sensor flag being stuck in the wrong position. As paper exits out of the machine the last flag. Typically on the outside of the machine raises then lowers. After you get X amount of paper in the output area as the paper exits the printer the flag cannot lower till the already printed paper is removed. I see this sometimes happen in my hast to reinstall a top cover. So for Tracie I would check the out put area and make sure the flag is not hung in the up position. On Market Points home site you can find service manuals for various machines. I would check there and refer to the troubleshooting chapter for more details on the error and locations of the sensor flag and sensor.

  18. We recently received this tech support inquiry. Please comment if you can provide any assistance!

    Question: On my HP Color LaserJet 2605dtn, I was experiencing the common problem of red color fadeout. I cleaned the mirrors according to the online instructions I found, being careful to reattach all connectors the right way. The machine restarted fine, and passed its diagnostics. But now all it prints for a self-test, a report, or a file sent to it, is a solid blue page. Do you have any hints or suggestions about what I could try? Or what I could ask a printer repair person to look for? I’m [in] a very small town so I would have to cart the printer a long way to a city to find a repair person. I have looked at the “service manual” for the 2605 but it doesn’t say anything about this symptom.

    Here is Kevin’s Response:Does the page have a defined border or does the cyan run from one edge to the other? To verify if it’s the cartridge or the slot you could open the front door and tell the machine to print a config page. Switch the cyan cart with one of the other carts then close the door. It should print a page then give you a cartridge error. Also try printing off an engine test from the engine test button. My first thought is that either the laser scanner is not seated properly or one of the laser scanner cables is not seated fully or in the wrong slot. Hope that helps. You have me stumped on this one. I haven’t really run into this problem. I also might look to see if the cyan was on the transfer belt after page was printed. Might do a half test and stop the page half way through to check to see if an image was on the other drum units.

    • Measure the distance between defects. If it’s 14mm, 33mm, or 39mm or if the double image appears to be only one color it’s probably that toner cartridge. If the defect is 38mm and appears to be all colors, it’s most likely the image transfer belt. If the measurement is 63mm the problem will be the fuser.

    • Answer from Kevin: Did you do the calibration after you cleaned the laser scanner assembly? Sometimes they say it needs to be run 3 to 5 times before it corrects. Other wise could be dirty sensors. A nvram reset or super nvram reset would be the next step. Sometimes thats the only way of getting the incorrect numbers out of the DC controller.

  20. Just a follow up in case anyone was having the same issues. We worked directly with Lexmark support to solve this issue. First we made sure all of the drivers were Post Script and the printer was set to emulate Post Script. Then in the printing preferences (not printer properties) there is a tab labeled “Other Options” Checking the box “Generate Postscript in driver” fixed the firmware error messages we were getting. Unfortunately this option doesn’t globally configure the printer so you’ll have to do it for each account on the computer.

Since this is an office printer its hard for us to reproduce the problem. We only get notified when the error occurs. As I’ve mentioned it only happens with pdf documents. We’ve tried several different drivers and a firmware update but the problem is still persistent. Although it only happens once or twice a day it is becoming a nuisance. I’ll try printing the pdf as an image mentioned in the comment below….is this something I should permanently switch to using since the office is constantly printing pdf files?

    • This is a “Mismatch between EEPROM and mirror motor” error.

      This could be a problem with the controller board, the operator panel, or both. Only install one component at a time when replacing, and be sure that board and operator panel are new OEM or rechipped to virgin status. Do not use a board or operator panel from another machine to troubleshoot printer.

I have changed the wear strips in the paper tray, rollers, toner cartridges and still have the problem. The paper simply stops under the toner cartridge just before it gets to the transfer roller of the photoconductor unit. The paper is not damaged at all. I just don’t want to keep ordering parts until I am confident of the problem.

    • he error means that the printer/MFP is experiencing a ‘warm up’ jam. It means that the Input Sensor is covered with paper that is not expected (paper in machine during warm-up).

      Please follow recommended action below:

      1 Remove the tray from the printer/MFP. Remove the jammed paper, if you find any.
      2 If you do not see any paper, open the front door, and then remove the photoconductor kit and toner cartridge (unit). Remove the jammed paper, if you find any.
      3 Note: Please check for any damaged parts inside the printer/MFP. If any parts appear damaged, a service call will likely be required to resolve the issue.

      4 If you cannot find any paper jammed inside the printer/MFP, yet but it continues to display the same error, the printer/MFP may have either a broken or stuck Input Sensor (Gray Flag inside the printer/MFP).
      5 Note: The Input Sensor is in standing up position and easily moves back to the standing position when pushed down.

      6 Check and ensure that the Input Sensor is standing up position and moves freely with no physical damage.
      7 Note: If the Input Sensor moves freely and shows no physical damaged, replace the Duplex and Media Sensor assembly (FRU 40X5365).

      8 If you are printing from the Multi-Purpose Feeder (MPF), and printer/MFP pulls paper as it warms up, replace the MPF Feed Clutch (FRU 40X5371).
      9 Note: If issue persists after performing the steps detailed above, replace the Media feed (ACM) Clutch assembly (FRU 40X5370).

      Here’s a little from a post of mine last August:

      “Under the Fuser Wick Assembly Cover you’ll find either the Wet Wiper Assembly (early models; T52x through T62x) or the Fuser Wiper Cavity Cover (later models: T63x and later). If the Wet Wiper Assembly isn’t replaced regularly it becomes caked with excessive toner and causes scratches on the heat roller. The Fuser Wiper Cavity Cover is ‘permanent’ so it’s not dependent on end-user replacement.”

      The blank one is the “Fuser Wiper Cavity Cover” and should be used for regular printing in all late model T series from T630 and up.

      The felt ones are for specific uses like labels and duplexing labels (oil for regular labels, wax for duplex labels), as follows:

      56P1423-WIPER ASM,FUSER,T63X

    Question: Could you assist our dealership. We keep running into Lexmark T630 series printers with light print trouble. Being in the service industry for over 39 years we have pretty much thrown the kitchen sink at the ‘light print’ issues with little to no success. Any suggestions?’

    Response: I’m going to assume you’ve done the cleaning, Restore EP Settings, power supply checks and multiple toner cartridges, both re-manufactured and OEM, since you mentioned the kitchen sink…. 🙂

    What we’ve found, especially with the T630s and light print, is the time consuming process of determining the machine specific combination of new and used transfer rollers and charge rollers. Some T630 printers want both new, some want both used, then some want a combination of new and used. (ex: new charge, used transfer; used charge, new transfer).

    • There is no way to reset a NVRAM Mismatch error from any kind of power on reset sequence, to the best of our knowledge. The operator panel was probably pulled from another machine which caused the error after installation. The operator panel needs to be a virgin OEM part, or a rechipped operator panel from a qualified vendor, like ourselves.

    • If your doing the maintenance in-house read page 2-14 of the Lexmark C935 service manual. That will direct you to page 2-91 and give you a better step by step procedure designed by the manufacturer. POR is just power off…. wait a minute or so… Power on. There is a POR Sequence on page 2-2 that tells what the printer should do once you power on.

      As far as a reset for your problem? It doesn’t exist because the cards have to be re-chipped. And the manufacturer wants to do that. Read thru 2-14 and 2-91 for a clearer presentation.

      If you just bought them I’d recommend getting ahold of IBM or Ricoh (this printer is their joint venture) or whoever you bought them from for warranty service.

      If they’re out of warranty and you need a manual Market Point has them as PDFs. Right guys? 😉

The printer is rated at 55ppm, however it slows by design to approximately 20ppm when printing narrow media. I found this out when I actually started printing. It slows due to the need to reduce the temperature on the non paper touching part of the fuser.

    • I’m thinking that the reason you can’t find any paper is because it never left the tray. It’s all about timing. If the paper doesn’t close the first sensor in the paper path at the right time the machine says it’s jammed.
      Change the Feed Roll Kit (Part# 40X4866 – around $60 retail). That’s the first and least expensive fix. You’ll be able to do that yourself. Open the tray when the part gets there and match it up to the roller in the tray. Easy-peasy… If that doesn’t fix the jamming I’d suggest calling a tech. It’s gets complicated and messy after that… 😉

  34. I have a Lexmark C530dn ;azer printer and I had to replace the printhead with a new refurbished printhead.Now the printer displays error 950.10 NVRAM MISMATCH.Do you know how reset the printer or erase it s memory?

    • It’s possible that a refurbished printhead may not been brought back to virgin state. There’s no reset for that. Additionally, when replacing the printhead (or any one of the following components: Operator panel assembly, System card or Smart chip card; only replace one component at a time. Replace the required component, and perform a POR before replacing a second component listed above. If this procedure is not followed, the printer will be rendered inoperable.

      Give us a call, toll free, at 877-365-1903 ext. 4 to talk to a tech support specialists who can further help you troubleshoot this problem. They just need a little more specific information, like the original cause of the printhead failure, etc. Tech support is free.

  35. I’m in the middle of an HP P4015 that squeals when printing from tray 1 (MP tray). The squealing can also be heard after 40 or 50 pages of continuous printing from tray 2. It was suggested that I replace the Pick-up Motor Assembly. The first tech thought it was the Drum Motor Assembly. So I just replaced both motors. There is no change in the symptoms at all. The noise seems to stop once th paper has cleared the imaging portion of the printing process. By that I mean once the paper has gotten to the Faceup tray assembly the squealing stops. So, fuser? Fuser Motor? Laser?

    • I hope you tried a new toner cart? Squeaks or squeals usually come from dry parts rubbing on other dry parts. Ive probably replaced 4 or 5 motors with the exception of the HP 4L’s and laser units in the last 10 years for problems. Motor would have been the last thing I thought to replace. Other things to try are: remove the transfer roller and run a few copies, Open up the back door and let it feed out the back. I beleive you have four white idler rollers on the door and they have been know to sqeak. I dont know if when you open the back door the top exit assembly stops working but if it doesnt the pull it out remove the gear that drives it and run a few copies out the back to see if the noise stops. As usual you need to isolate the problem by checking parts and eliminating various parts of the machine. Being a tech is troubleshooting then replacing not just replacing. Laser motors usually dont go in and out. Usually when they start to go it constant. Other areas that I sometimes here sueaks are the transport area just before the fuser or the registration area. Does it squeak on start up? Or only when printing?

        Well ‘strydur’, you don’t know me, my background, the circumstances or conditions I’m working under. The judgemental statement above assumes a lot. That you’re a better tech than I am. That you have more experience than I do. Neither of which was proven by the solutions you offered. Your unprofessional reply, along with the following statement from ‘nivek’ have given me the impression that the arrogance has gotten in the way of the professionalism on this blog.

        ‘nivek’ “Before replacing parts your suppose to troubleshoot if I remember right?”

        I was under the impression this was a place where technicians of all levels could communicate. If somebody is experiencing a problem of whatever magnitude, maybe even just a brain fart, they could send an SOS here and get a response from another professional who has had the same experience and can offer some quality guidance. I guess I was wrong. And I will go elsewhere for help.

        This ain’t the only source on the web, buddy.

        And neither of you are the absolute best at your craft. Not even the smart-assed part.

  36. We received this recent inquiry and thought it was good information to share!

    Question: I ordered a Formatter Board from y’all and swapped it out in a stubborn P3005X printer. That printer sat “on stand-by” for a while , until I finally re-commissioned it at a branch location. I think it worked for a few days, but then proceeded to act up once again. Unique (for me, anyway) to the P3005 is the status messages during boot-up. I believe, very near the end of the POST, a failure message jumps in: ERROR – 68.0 Permanent Storage Write Fault I think I did transfer the RAM stick from the old board to your new board, if that’s what it’s referring to. But I figured I might ask your expert if that’s this issue and if so if you recommend replacing or re-seating the memory. If replacement makes sense, then “do you have it for sale? “, basically.

    Answer: Is this a network or non-network machine? Hopefully you installed a network board in a network machine or non-network board in a non-network machine. The memory chip must be 32mb or higher for a network board or 16mb or higher for a non network machine. My experience with the 68.0 errors is that they are caused by the ECU board. The chip on this board has a tendency to fail. The ECU failed board can also cause the matching chip on the formatter to fail. I recommend you try this formatter in a known working machine of the same type. If the formatter works fine in another machine then you should replace the ECU board, Part# RM1-3730.

    Like

    • Well before you start replacing boards that might not need replaced you should first try a few things. Before replacing parts your suppose to troubleshoot if I remember right? First the 68 error is generally a recoverable error. Usually by pressing the go or select button the machine will continue. On some models in the config device menu you can set the next job to clear the message. Second the error is a NVRAM error so trying a NVRAM initialization could correct the issue. I’ve also seen corrupt firmware updates cuase this error reinstallation corrected the issue. Third their are several different methods recommended when replacing the formatter with refurbs. Some say to let the machine set at a ready state 10 to 15 minutes before powering off after turning on for the first time. Others say to perform a NVRAM inialization when the machine is first turned on after a formatter repalcement. The theory behind this is the newer HP boards are holding more information on the various boards to allow updating. If one board is replaced they gather information from the other boards so they all hold the same information. If this doesnt happen then odd problems or loss of some functions can result. Use to see this all the time with the old 4100 series on startup. Pressing the go or select button removed the error on the machine carried on like nothing ever happened until it was turned off and on again.

    • I believe on that model if paper doesnt feed from the tray you get a paper load error. Paper jam errors are jams inside the machine. I might be wrong but it sounds like the print is on the page just not fused so it makes me believe its something in the fuser. More detail of where it jams and if print is actually on the page would help.

  38. I have two HP Laserjet 1000 printers. Although both appear to have quit working properly for me, I will focus on just the one I have troubleshooted recently. On a brand new install of Windows XP SP3, on a brand new install of the printer using the drivers from the HP website, I find that the printer installs fine, and accepts a print job. However the job quickly disappears from the queue, and short of warming up, the printer is unresponsive. Suggestions?

  39. Can somebody explain how the fuser in an HP 8150 causes a no duplex condition? I’ve been told this is an old problem known to most techs since the machines came out. But no one I’ve talked to here knows what in the fuser causes the problem, or how to fix the fuser.

    Like

    • Not sure of your situation but for some reason some fusers and duplexers dont get along. You remove the duplexer and it works fine. You interchange the parts with known working machines and they both work but together they dont. Does the machine recgonize the duplexer but does not work? I’ve mainly seen it on 5si’s. I tend to lean towards a power struggle between the two parts. As the lamps age they draw more power to heat to the correct temp. drawing power away from the rest of the machine. So when it tries to duplex it doesnt work and the machine jams. Two other things to check if you just installed the duplexer for the first time are the memory. Machines need addtional memory to run the duplexer and while the 5si and 8000 duplexer look identical to the 8150 they are not the same so make sure you have the right one. If all else fails then try a new fuser instead of a rebuild. Some more info on what is really going on will help to further troubleshoot the problem. hard to say foresure what your issue is with the little info you have provided.

      Like

      • The fuser and duplexer worked fine together for years. Then started jamming only when duplexing. Printer works fine when printing with no duplex. I swapped the duplexer with a known good one with no difference, still jams when duplexing. Took the suspect duplexer and put it in a known good 8150 and that printer duplexed with no problem.

        The known good printer won’t duplex with the suspect fuser installed, though. So it is definitely the fuser.

        Called a tech I know with a lot more than my puny 6 years experience. He said that this is a well known problem and that the problem is with the fuser. So I traded fusers with the known good printer and ‘poof!’ it prints fine even duplex.

        Your thought about the lamps getting old was what I was thinking because SL3 that is supposed to operate the Flapper in the Diverter doesn’t sound right. Doesn’t sound like it kicks at the right time.

        I’ve compared the bad fuser with a new one physically and couldn’t find any differences. So I was hoping somebody else would come up with extra load on the power supply from the fuser. Thanks.

        My customer is up, running, and happy after I replaced the fuser. Right now I’m experimenting with this fuser to find a solution to the problem so I can fix it quicker next time it shows up. So now I’ll replace the lamps with new and try it again.

        Thanks much for help, and validation… 😉

  45. I’m in need of some serious help with 3 Lexmark T640’s…

    All three are squeaking. Seems to be coming from the same place, left rear as you face the machine, but nothing I’ve tried has cured the problem.

    I’ve tried vacuuming the interior, new toner carts, re-drive assemblies, fusers, even greased gear trains.
    But nothing has made a difference for long.

    I’ve compared the machines for some hint, but I can find no common ground.
    They were installed, new, up to a year apart, so the page counts are very different.
    And the serial numbers aren’t even close.

    Could really use some help here. All 3 are owned by the same company.
    This has been an on-going problem for a couple of months and they are starting to lose confidence in our repair capability.
    And I’m begining to wonder if I know what I’m doing.

    Is this something inherent in that model?
    All Lexmark models seem to have their own quirks maybe this is the quirk for the T640.

    What am I missing?

    • First guess would be redrive assembly. I dont know how your going about resolving the issue. but we need to Isolate the problem. I hope your replacing parts one at a time. Wierd squeaks could come from dry bushings, and Idler roller clips. Im not as fimilar with the model. but I diffently would remove the redrive and run the machine without it to see if the noise goes away. I found a link but its pretty basic and I dont know if it will help.

  52. When replacing any one of these components – System board assembly, Operator panel assembly (upper front cover), or Interconnect card assembly – only replace ONE component at a time. Replace the required component and perform a POR (power on reset) before replacing a second component. If this procedure is not followed, the printer will be rendered inoperable.

    Never replace two or more of these components without a POR (power on reset) after installing each one or the printer will be rendered inoperable. And NEVER install and remove any of these components as a method of troubleshooting. Once a component has been installed in a printer, it cannot be used in another printer.

    And, just so you know – these same procedures must be followed for many other printers, including Lexmark T642 & T644 as well as Dell printers 5210 & 5310 and IBM’s InfoPrint 1532/1552/1572.
