HP Color LaserJet 3000, 3600, 3800, and CP3505 “Cartridges Not Engaged 10.92.YY” Error


The 10.92.YY Cartridge Not Engaged error is one of the more common error codes found on the HP 3000 series Color LaserJet machines. The good thing is that it’s one of the easier problems to diagnose. The bad news is that usually one or more of the cartridge lock levers or a slide lever is broken or one of the cams above is broken. Like the swing plate gear in the 4200 series HP LaserJets, the lock levers in this machine were never meant to be replaced. In this article, I’ll talk about the error, troubleshooting the error, and replacing the lock levers.

How the Cartridge Engage Process Works
As the transfer unit opens the cartridge lock levers (four on either side of the machine) move up into the machine. When the transfer unit closes the cartridge lock levers clamp down on the sides of the cartridges and hold it in place. On the right and left side, the lock slide levers moves up as the door/transfer assembly closes and down as the door/transfer assembly opens. When the right white slide lever moves up it engages the cartridge drive motor assemblies by pushing the black cartridge drive gears left so they mesh with the gears on the cartridge. Also, four white tabs on the right slide lever push on the back of the cartridge shutters moving them out of the way and exposing the drums. The lock levers are attached to the slide levers with springs. If any of these parts are broken or processes don’t happen then a cartridge not engaged error can result.

Alright, that’s how the process works. Now let’s move on to the troubleshooting part.  Continue Reading

Troubleshooting Lexmark 4069 Fusers – Part 1


In my previous post I wrote about Lexmark T-Series fusers in general. Now I’ll get more specific. In this post I’ll try to provide some, hopefully interesting, observances about individual model idiosyncrasies, challenges and opportunities.

Remember, I’m not trying to tell anybody how to troubleshoot. Nor am I claiming that all the information contained here is gospel. This is just some stuff I’ve noticed, experienced and talked with other techs about over the years. It’s information that’s worked for me. I hope it works for you.

At the outset I’d like to say that Lexmark fusers are ‘complicated simplicity’. I said in the last post that Lexmark hasn’t changed much of the basic design since the Optra S. That’s the ‘simplicity’. The ‘complicated’ enters the picture with the number of little variations within each model according the Type Number.

Let’s begin our fuser journey with the Lexmark T61x.  Continue Reading

End User Tips on Fixing Common Problems


Every printer is bound to have problems arise over its life time. Some problems will be easy enough to fix that your customer can handle it. Other problems, of course, require the skills of a professional service technician. In this article I will touch on some of the easy fixes that customers can mostly likely handle on their own.

Tip for Service Companies
There are many reasons why some of the easy problems most customers can handle on their own can effect a service company’s reputation. While it’s fun for us techs to go out to a customer’s office and tell them they just have a defective toner or clean white-out off a glass strip and charge a fee, our goal is to make our customers happy. One key to doing that is to make sure they don’t see us all the time to fix minor issues. If your customer’s Accounting Department sees constant billings from a service provider they start to wonder if they are doing a good job. It might not be the techs fault, but the customer paying the bills might not see it that way. While educating your customers with a few tips might, at first, seem like a bad idea from a financial point of view; it can go a long way toward promoting a trusting, honest relationship with your customers for a lasting relationship and a good reputation.

Of course not all customers care about fixing their own printers. Some just want the printer fixed and done whenever there is any kind of problem so, when attempting to give tips and advice, pay attention to your customer. If they seem uninterested, cut the conversation short and move on. Not everybody cares for free advice.

HP P3005 Formatter Board Issues


The HP P3005, like the P2015, is known to have formatter board issues. The typical signs of formatter board issues on this printer are:  (1) a blank screen, (2) the printer freezes during memory check, (3) the HP logo is stuck on display, (4) an RFU load message, and (5) 49 errors. These are just the most common errors. You could experience other issues or messages due to the fact that the problem is with a chip on the formatter board.

Like the HP P2015, a design flaw causes the chip temperature to melt the solder used on the board, which breaks and causes a poor connection. HP could have used a stronger solder material to withstand the thermal stress or could have added a heat sink or fan to cool the chip. And, like the P2015, most board repair companies have figured out a way to resolve the issue for the long run.

HP, on the other hand, is still trying different chips to solve the issue. I recently learned that HP just released yet another version of the board but the verdict is still out as to whether this will finally solve the issue. The web is flooded with unhappy customers who have had boards replaced by HP just to have the same problem again, six months later.

Troubleshooting this Formatter Board Problem

The first thing we need to do is verify what is causing the issue. To do that, first unplug and remove any accessories, such as optional trays, or memory or jet direct cards, and then reboot. If the error goes away, reinstall the accessories one at a time unplugging each time before the next component is installed until you find the component causing the issue. On some machines the error isn’t always present so reboot a few times if the machine starts working to verify if you actually resolved the issue.

If, after removing the accessories, the error is still present then we need to perform an engine test. The engine test bypasses the formatter and tests the basic engine functions to verify the machine’s print engine is physically working. To perform this test you need to remove the right side cover and find the engine test button located a few inches down from the fan cover.

HP P3005 Engine Test

The engine test bypasses the formatter and tests the basic engine functions. To perform this test remove the right side cover and find the engine test button located a few inches down from the fan cover.

You might need something small, like a paper clip or canned air straw, to depress the button. In some cases the formatter might prevent you from performing the test so the formatter might need to be removed before the test will work. On one machine I worked on recently, by pressing on the chip above the memory card slot, the chip known to cause these errors, the machine booted up to a ready state but failed when chip was not pressed on.

Confirmed Printer Formatter Issue

If you’ve gotten an engine test out of the machine, we verified a formatter issue. We have a few options of how to proceed. You can

  • replace the whole machine with a new or refurbished unit,
  • have the board professionally repaired,
  • replace the board with a new or refurbished board
  • try the homemade fix (not recommended)

Replacing the printer with a new or refurbished printer

I personally frown upon this unless, after inspecting the whole printer, you find other problems like a worn printer fuser, noisy scanner motor or a large copy count. In other words, big ticket items that will lead to a costly repair bill.

I like knowing the history of printers that I service and with past experience with refurbished printers you never know what you’re getting. It’s like buying a reconditioned cartridge. Two out of ten will probably give you issues. New printers, unless justified with the overall condition of the unit or repair bill, just makes people believe they are throw away units leading to less service calls. And if you have a large repair bill just for a formatter board replacement you need to shop around because someone is taking advantage of you.

Buying a new or repaired formatter board

This is the first choice I always make. Get yourself a reconditioned formatter board with a warranty from a professional, reliable company like Market Point. HP just added a new version of the board so I wouldn’t trust new since they haven’t figured it out before now.

Sending the formatter board in for repair takes time, which you usually don’t have and if you repair for a living, like me, it makes you look bad because one of the keys to service is quick and reliable turnaround. So rebuilt and warranty, even though you might pay a little more than sending it in, gives you the quickest and best results. And in the eyes of your fellow employees or customers makes you look like the hero because in today’s world quick response is key to success.

The homemade fix

You can find this repair on several places on the web. Due to the nature of the procedures, if not performed correctly, further damage to the machine or to yourself can result. So I believe Market Point does not want to be held responsible due to injury resulting from information posted on their website. I personally have performed these procedures and fixed machines but the results will vary and while it might get your machine running again, it’s not the same as having it professionally done. In the long run I would recommend purchasing a reconditioned board that has been professionally reworked and has a warranty.

Hopefully, this article has helped you resolve your P3005 formatter issue. I expanded more on your repair options in this article to help you make an informed decision when it comes to your options. As I stated with the HP P2015, the P3005 machines are great machines and when working properly do an excellent job. Given the history over the last ten years, more and more problems are happening with the newer models. If spending around $200 to fix this machine does the job and the machine is in good condition then it’s probably in your best interest to fix rather than replace and spend $600 to $800.

HP Printers 49.XXXX Service Errors


In the past several years 49.xxxx service errors have become one of the most common errors associated with all models of the HP line of printers. In this article, I’ll discuss the meaning of the error, what causes it, and gives some tips on trying to fix it. Yes, I said try. Given the nature of the errors each one is unique and what might work on one will not work on another. So patience and a little bit of luck might be needed. Read on…

First, the 49 error is an internal communication problem. The firmware has had a critical error and the formatter processor has aborted its operation. XXXX refers to the address of the fault. This doesn’t mean much to end users but HP likes to record these so if they start seeing a high level of errors with the same fault address they can focus on making changes with the firmware or other parts to prevent the error from recurring.

HP’s service manual says the 49 error can be caused by a bad print command, corrupt data, invalid operations, firmware, formatter, or possibly by accessories like an EIO card or memory. Some reports even say extra trays, duplexers, envelope feeders, etc., under certain circumstances, can cause this error.

With the amount of 49 errors and the ranges of fixing them I wouldn’t necessarily say it’s caused by a bad command or corrupt data. That’s HP’s way of saying ‘it’s someone else’s fault.’ The truth is there are lots of other manufacturers out there that aren’t having this problem.

Many of these 49 errors are happening with newer software, file types like PDFs, special fonts, formats, or pages pulled off the internet. So, the reality is, HP’s driver/firmware software doesn’t seem to be keeping up with the rapidly evolving software industry. I will say that recently I was checking out some firmware fixes for a few printers and was surprised to see several 49 errors being addressed in the firmware updates. So HP is aware of these issues and attempting to correct the problems.

Isolating the problem
Many times, users power off, and when they power back on the printer starts working.  Shortly thereafter, or within the next few days, the 49 error reappears and a service call is needed.

I suggest the following steps to isolate the 49 error problem:

(1) Power off the device and disconnect any communication cables; Network, USB, or Parallel cable. 

(2) Wait 30 seconds and turn the device back on. If the error is still present then we know we have a device error – move to step #3. If the error goes away, see Communication between the computer and network (below).

(3) Unplug the printer and remove any accessories like EIO cards, memory, extra trays, duplexer (if removable), and envelope feeder. If the error goes away when you power back on, start reinstalling the parts one at a time, powering off before installing each part until you find the part causing the error. Once you’ve isolated the problem part, before replacing that part, check for any firmware updates and then reinstall the part. Some firmware updates fix this type of issue.

If the 49 error is still present after removing everything possible, try a cold reset or NVRAM initialization (see service manual for details). A cold reset resets minor stored memory settings like control panel settings or internal and external jet direct settings, so, if possible, know these settings before proceeding or remove the jet direct card. NVRAM is more evasive and clears out more of the internal memory like error logs and certain counters.

If the 49 error persists, it’s time to replace the firmware DIMM, if there is one, or to replace the formatter board. On extremely rare occasions the DC controller or power supply can be at fault. Check the service manual for specific 49 errors related to these parts. 

Communication between the computer and network
More than 95 percent of the recent 49 error faults are communication/software related. If the printer is connected to one PC we simply see what file was sent to the printer last (usually still in your computers print queue). Note the file and delete the job from the queue.

The printer’s service manual says to download the latest and greatest firmware or driver. I, personally, have fixed lots of the 49 errors just by changing the driver. Most HP printers have three drivers; PCL 5, PCL 6, and Postscript so first, simply try another driver. I usually go with PCL 5 or PCL 6. Most of the errors I see are when using the Postscript driver. HP likes to show the fixes beside the driver and firmware so check them out. As I mentioned earlier, I was surprised at the amount of 49 errors being addressed on the few I looked at.

Once the driver or firmware is changed, reprint the problem print job. If you’re still getting an error, try downloading a generic universal print driver, which you can find in the same section as the firmware and driver downloads on HP‘s website.

Converting the document
If, after trying all drivers and updating the firmware, you are still getting the 49 error, convert your document to another software application. For example, convert a Word document to a PDF or vice versa. The logic behind this is that you probably have a command in the document that the printer doesn’t know how to handle. When you convert the document to new software the data is reformatted.

Still getting the 49 error?
Most errors should be fixed by following the above steps. Still, I know of cases where all of these steps were tried and the printer still gives the error. As I stated earlier, the causes of the 49 error are vast and each one is unique. As a last resort, find the offending print job and try printing it to a different printer. I did see on firmware released this year HP has added an auto recovery feature. Read more here: Auto Recovery Feature for 49.xxx Errors

For printers on the network, trying to isolate the issue can be frustrating and time consuming. If you have a server print queue, check the queue for the offending print job. If print jobs aren’t stored in a server print queue, you will have to go around individually to each workstation to find who is sending the offending job. Once found then follow the steps in the previous section.

Ask Questions
I’ve found that most 49 errors occur when someone has recently installed new or old software, downloaded something off the internet, created a new file, or tried altering a document by changing fonts, color scheme, adding a picture, or formatting. Ask questions! Look for something that has recently changed, even the smallest detail can be the most important.
