HP Color LaserJet 2500 - Error 54.07 All Lights On

This error occurred on a long print run after 100-200 pages. The printer stopped mid print with the  Attention light, Ready light, and Go lights all on indicating a service error.

If the printer has a service error (Attention light, Ready light, and Go light are on), press and hold (GO) and (CANCEL JOB) simultaneously to see the secondary error message.

Doing this, the Attention and Ready lights were on. This secondary fault code wasn't in the service manual. Although the Hewlett Packard Color LaserJet 2550 sevice manual lists this as a carousel error.

Turning the printer off and back on resulted in it trying to initialise with a lot of clunking noises coming from the carousel and the error coming up again. With the top off and the lid switch defeated, the carousel was seen to judder forwards and backwards.

After the printer was left switched off for a while, it was possible to print a config page by pressing the Go and Cancel buttons. The error log on the config page showed a 54.07.00 error. Again, this error isn't listed in the service manual.

This fault was caused by the rotary motor assembly, part number RG5-6958-000CN. This is the motor on the rotary drive assembly that turns the carousel around.

To remove the rotary drive assembly:

1. Remove the left and right side covers by removing one screw at the bottom of each, pulling the bottom out, and lifting off at the top and front.
2. Release two tabs on the interface cover on the back and remove.
3. Release two tabs on the rear cover and remove.
4. Open the top door, remove the gear on the right hand side, and remove the top door rack. Refit the gear.
5. Remove three screws and lift the top cover off.
6. Lift off the top output bin cover.
7. Remove five screws from the formatter assembly and lift it up and off. Disconnect two cables as you lift it away from the printer.
8. Disconnect the three cables from the rotary drive assembly at the DC controller.
9. Disconnect the flat ribbon cable from the laser scanner assembly to the DC controller.
10. Remove four screws from the top of the rotary drive assembly.
11. Looking from the side of the printer, remove the left hand screw from the left hand motor on the rotary drive assembly.
12. Lift the rotary drive assembly out of the printer.

  The motor you need to replace is the longer one towards the rear of the rotary drive assembly. Remove the two screws, and the motor can be pulled out.

Reassembly is the reverse of this procedure. Take note of the following:

• Fit the the back of the rotary drive assembly into place first.
• Make sure the formatter assembly is hooked into place at the top. If it's sticking out at the top, the surface mount LEDs and resistors at the top of the formatter board can get knocked off when the right side cover is fitted.
• When you fit the top output bin cover, make sure the two plastic flaps fit over it and are not trapped behind it.
• Make sure the top cover is located properly in the top output bin cover.
• When fitting the side covers, hook them in at the front and top, and then push the bottom in.
• When you fit the right side cover, it might be best to remove the control panel first. When you fit the control panel into the cover, ease the top of the cover away from the printer. This can prevent damaging the surface mount LEDs and resistors at the top of the formatter board.

HP Color LaserJet 3000 3600 3800 - 10.92 Cartridges Not Engaged

The most common cause of a 10.92 cartridges not engaged error on a Hewlett Packard Color LaserJet 3000 / 3600 / 3800 is broken cartridge locks on the right hand side of the printer. Another possibilty is the slide lever that operates the cartridge locks is broken.

This is the diagnosis of this error from HP's service manual:

10.92.YY CARTRIDGES NOT ENGAGED

The print cartridges are not engagedcorrectly. YY Description: 00 Black 01 Cyan 02 Magenta 03 Yellow

● Open and then close the front door. ● If the message persists, make sure allthe print cartridges are seated correctly. ● Clean the contacts on the memorycontroller PCA. ● Make sure that connectors J302, J303, J304, and J305 on the memorycontroller PCA are seated correctly. Also make sure that connector J1020 on the DC controller is seated correctly. ● Replace the memory-controller PCA if it is damaged. ● Check the gears on the print-cartridge drive motors. Replace defective motors. ● Replace the DC controller.

10.92.YY CARTRIDGES NOT ENGAGED The print cartridges are not engaged correctly. YY Description: 00 Black 01 Cyan 02 Magenta 03 Yellow ● Open and then close the front door. ● If the message persists, make sure all the print cartridges are seated correctly. ● Clean the contacts on the memorycontroller PCA. ● Make sure that connectors J302, J303, J304, and J305 on the memorycontroller PCA are seated correctly. Also make sure that connector J1020 on the DC controller is seated correctly. ● Replace the memory-controller PCA if it is damaged. ● Check the gears on the print-cartridge drive motors. Replace defective motors. ● Replace the DC controller.

If you follow this procedure, you will end up replacing the DC controller which won't repair the fault.

What you need to do is slowly open and close the front door. Make sure that the flaps over the front of the print cartridges move. If you look carefully, you should also see the white plastic drives insert into the right hand side of the print cartridges. Also on the right hand side, you should see the levers lock the print cartridges in place.

If you don't see any of these parts move, the slide lever might be broken. If these parts do move, remove the print cartridges and inspect the plastic levers that lock the cartridges in place on the right side of the printer.

If the cartridge locks are broken, HP will send out an engineer to replace them free of charge, even if the printer is out of warranty. Phone up the warranty support line and tell them the plastic levers that hold the toner cartridges in place are broken. If the printer is out of warranty and they start offering you the paid options, remind them that there's a service note that covers this fault.

UPDATE

The service note for this fault ended 1st October 2008. You will have to repair it at your own expense now.

If you decide to do the repair yourself, the part numbers are Q5982-67925 which is a set of four cartridge locks and springs and should include instructions. The part number for the slide lever is RC1-6643-020CN.

Be warned, it isn't easy to replace the cartridge locks or the slide lever. I'm not going to describe how to do it. Instead I've provided links below to download the replacement instructions and the service manual.

The service manual is over 17Mb in size and you will only need it to remove the covers. The replacement instructions are only just over 1Mb and you definately need to download and read this.

Follow the instructions closely and pay particular attention to the location of the screws to remove the main drive unit and the gear alignment when reassembling the printer.

HP LJ P3005 PRINTER
55.00.00 DC CONTROLLER ERROR
HOW TO REPAIR THIS ERROR
PLEASE HELP ME

admin

This is from the HP LJ P3005 service manual:

55.XX.YY DC CONTROLLER ERROR alternates with To continue turn off then on.

The engine is not communicating with the formatter.

1. Turn the device off and then on.
2. Verify that the flat ribbon cable between the ECU and the formatter PCA is connected correctly.
3. If the message persists, replace the ECU. If the message still persists, replace the formatter.

If you do need to replace the ECU, you can find the instructions in the service manual here (right click to save):

HP Color LaserJet 2600 - Image Ghosting Or Repeating Down The Page

Image ghosting (image repeating itself down the page) on a Hewlett Packard Color LaserJet 2600 when first switched on or after it has been idle for several hours can be cured by a simple firmware update.

Measure the distance between the original image and the repeated image. A measurement of 56.6 mm indicates the fuser needs replacing. Before you buy a new fuser, check the firmware version of the DC Controller.

You can do this by printing out a config page. A configuration page can be printed from the printer control panel (press the green Select button, then press the left (<) or right (>) buttons to navigate to the Reports menu, press the green Select button - press the left (<) or right (>) buttons to navigate to Config report and press the green Select button).

At the bottom of the printed configuration page a line beginning with CPR and then a group of numbers followed by EV= will be shown. The latest DC Controller firmware (1.47) will show as EV=2F.

If the value of EV is lower than 2F, such as 2A, you need to update the DC Controller firmware.

This is the HP description of the fix for this firmware update:

Corrects fuser offset (ghosting) that typically appears on the first print jobs after the printer has been idle for several hours. The offset or ghosting typically appears on the left or right margin but is not limited to those areas.

For some reason, HP have removed the firmware file from their website. You can still find the Mac OS X version on HP by searching for it. You can find the Windows version elsewhere by searching Google for 2600_DCC_FW_Update-14701.exe.

Or you can download the Windows version by clicking the following link (you will have to unzip the file):

2600_DCC_FW_Update-14701

This is the version I use, and have used recently, so it works and shouldn't contain any viruses.

You need to have the printer driver installed on your computer to run this update. Simply run the program and select the printer to update in the box that opens up.

DO NOT POWER CYCLE THE PRINTER during the update process or it may leave your printer in an unusable state.

During the printer firmware update, the LCD display on the printer control panel will display "Initializing" and the green and amber LEDs will begin flashing. After several minutes the green and amber LEDs will go solid and the printer will make a noise as if it is warming up. The display will then change to " Turn off then on". At this point it is necessary to power off the printer and then power on again.

Print out the config page again to confirm that you get EV=2F and your ghosting problem should be fixed.

Update

There are detailed instructions on installing firmware updates on this printer here:

HP LaserJet 4250 4350 - Grinding And Knocking Noise

If you get a grinding and knocking noise from a HP LaserJet 4250 or 4350, the problem is the swing plate assembly and / or fuser. The swing plate assembly is a metal bracket with two plastic gears on it and drives the fuser.

The problem is that the teeth on one or both of the gears wear. You might also find that the plastic clip that holds the fuser in place cracks. The new swing plate assembly is modified to reduce the wear on the gears. It is also supplied with a modified two part spring loaded fuser gear. The new fusers are also modified with a metal insert inside one of the plastic clips to stop it from breaking.

The good news is that HP will send an engineer out to repair it free of charge even if it is out of warranty. Tell them it is making a grinding noise from the back of the printer and that you have tried reseating the fuser. If they tell you the printer is out of warranty, remind them that there is a service note that covers this fault.

Update

As of January 1st 2010, HP are no longer repairing this fault free of charge so you will have to do it yourself or take your printer to someone who can do it.

If you decide to repair the printer yourself, there's a right and wrong way to do it.

The one gear can be changed very quickly by removing the formatter cover, formatter assembly, rear door, and fuser. Behind the formatter, you will find a black screw. After removing this screw, the gear can be removed from the back of the printer.

The problem with doing it this way is the printer will still be noisy if the other gear that you can't see is worn.

The best, and correct, way to do it is to replace the whole swing plate assembly which requires removing the power supply board and is quite a lengthy process.

Briefly, what you have to do is; remove the top cover, both side covers, rear door, and fuser. Disconnect the cables from the power supply board at the dc controller. Remove six screws and an earthing screw holding the power supply board in. Remove the power supply board from the back of the printer.

The swing plate assembly can then removed from inside the printer by removing the three black screws. These are hard to get to and can be tight and are easy to round off. The swing plate is also tricky to get in and out of the printer.

If you get a genuine HP part, it should already have some grease on it. If you get a cheap compatable part, you might need to grease it yourself.

When you tighten the screws holding the power supply in place, pull upwards on the power supply. This moves the fuser gear closer to the swing plate gear.

Fit the new fuser gear supplied in the kit onto the fuser. Don't forget to check the plastic retaining clips on the fuser. If they are broken, the fuser will need to be replaced.

Hopefully, your printer should now work, and should be a lot quieter.

Great post, maybe you could give us the part number of the swing plate?

admin

The HP part number is 5851-2766.
The description for the part:
Swing plate assembly – For Tray 2 paper lift assembly – Located between the main gear assembly and the fuser, just above the power supply – Contains swing plate assembly and new fuser pressure release gear .
is incorrect, it has nothing to do with the Tray 2 paper lift assembly.
