Troubleshooting HP Color LaserJet 4700 Printer Issues

I’ve found these machines to be among the better color LaserJet printers made. When OEM cartridges are used, I rarely run into problems and these printers require very little maintenance, most of which a customer can handle on their own. I have a few of these machines in the field right now that have over 1,000,000 prints. I believe these machines are well worth keeping around, if possible.

In follow up to Monday’s post, here are a few more troubleshooting tips for the 4700 LaserJet and the 4730 MFP.

HP Color LaserJet 4700 Light Print CMY Color Planes
A recent service called involved a machine that was printing light in all the colors. When I printed a config page I noticed that all the colors seemed extremely light.  The printer error report showed lots of CPR sensor errors and 54.XX halftone calibration errors.

The customer had replaced all the color cartridges (they were using OEM cartridges). Disabling the cartridge check in the diagnostics menu and swapping the cartridges, restoring the print quality settings, running a full calibration, and making sure its toner save was turned off did nothing to change the print quality. I took out the feed assembly under the cartridges and cleaned out the two color plane registration and density sensors. Once again, nothing changed on the print quality.

As a last resort I performed a NVRAM RESET Continue reading

What to do when your HP Color LaserJet 4700 has a Blank Control Panel

A few weeks ago I went on a service call for a HP 4700 that had a blank control panel. Once I arrived onsite I observed that the machine was turning on and going through its normal start up procedure. However, the control panel, while lit, had nothing in the display. The three attention lights on the bottom of the control panel were also lit. After reseating the formatter, compact flash, and 256 MB memory DIMM nothing changed. I could not print to the machine but it did print the Engine Test Page.

In this particular case I ordered the Compact Flash and Memory DIMM and it happened to be the memory DIMM that resolved the issue. The best advice I can give if you run into this issue is to remove any accessories plugged into the machine, including EIO devices, memory, and compact flash. Insert each device one at a time and see if anything changes. Start with the Compact Flash, then memory, then EIO devices. I found that the memory and compact flash were relatively cheap so obviously the best place to start.

Note: On researching this problem I did find a few topics where the machine locked up after doing the memory count where the battery on the formatter had gone bad.

Service Manual Troubleshooting Tips
1. Reseat Formatter
2. Reseat Compact Flash
3. Reseat Memory DIMM or DIMM’s
4. Replace Compact Flashes and Firmware Card
5. Replace Memory DIMM
6. Replace Formatter
7. Check Flat Ribbon Cable Connector From DC Controller to Formatter
8. Check Formatter power connectors for LVPS
9. Check Control Panel display connectors to DC controller
10. Replace Control Panel display

HP LaserJet 5si, 8000, 8100, and 8150 Gear Noise

This last year I’ve been experiencing more calls due to noise coming from the left side of these machines and, in extreme cases, the noise is followed by jamming in the face-down delivery assembly. When you close the back door on these machines a swing plate gear drops down and meshes with the top gear on the fusing assembly. Over time this gear gets worn down and a noise develops.

What I’ve noticed is that the swing plate gear noise is gradual and because these machines typically are noisy anyway, customers tend not to notice a problem until the printer starts jamming or the noise gets extremely bad.

To check this out, turn the machine off, remove the fusing assembly and check the gear. If you’re looking at the inside of the machine from the left side the gear is located on the bottom left part of the delivery assembly.  It’s spring loaded so you can pull it down and get a good look at it. If the teeth are worn down it’s pretty obvious. If it’s really bad and jamming all the time you can further test it by running a paper path test from the information menu and send it to the face up exit assembly. The paper will exit out the left side of the machine and drop on the floor if the tray is not there but this test will verify if the fusing assembly is causing the problem or not.

Another way to check is to see if the rollers on top of the machine are rotating. If the teeth on the swing plate gear are stripped out, the exit rollers on the top of the face down delivery system will not be functioning correctly. Sometimes they don’t turn at all and other times they will turn only intermittently. The gear is not sold separately so if you find this to be the case then you will have to replace the face down delivery system. It’s not a tough job and because of the age of these machines the parts seem to be getting cheaper by the day. Right now these are some of the cheapest HP machines to own and operate because of the cost of parts and toner.
