20 Most Recent Xerox Phaser 8400 Laser Printer - Page 3 Questions & Answers

The 37,004.40 error means that the ink reservoir is not heating up correctly. Make sure the printer is plugged in directly into the wall and not on a power strip and cycle the power to the machine (turn it off and back on). If the problem continues, you probably have a bad printhead which you have to replace. For the 8400 the part number is 650-4303-00. Iteminc.com has that part in stock and ships same day. Here is a video that shows you how to replace the printhead. Hope this helps and thanks for using FixYa.

Service Manual says:
37,020.47 = (8400) Strip Solenoid
37,020.47: Strip Solenoid disconnect.
The strip solenoid is not drawing the
expected power.

The Solenoid (relay) may be bad, or the power to it is low.


The Stripper Solenoid positions the stripper blade. The solenoid mounts on the Upper Inner Duplex guide and activates the strip solenoid lever, which in turn rotates the Stripper Carriage
until it hits the transfix ground pins. This action causes the stripper blade to drop onto the deadband of the Drum.

This seems to be fault in the transport of the paper in the rollers. So if you have used any adhesive sticker printing, it is possible that some glue has got clogged into the rollers. If not there can be some jammed paper in the rollers or the mechanism.
So start this work only if you are mechanically able with the right tools.
Remove the covers to get access to the mechanism . Remove the motor drive assembly , the fitting of the motor to the mechanism. Once this is removed the rollers can be turned manually so that you will be able to feed a paper to see the progress of the movement while studying if there is any obstruction or damage to the paper.
There is a in-detect sensor, usually an opto-coupler , make sure this is not clogged or dirty as this IR detection feeds the signal to the processor for starting the motor drive feed.
Reassemble but make sure the rollers are aligned to be in equal gap to feed the paper without a side pull. Now you must print and see if the fault has changed. If not repeat the above work to confirm the area of obstruction.

I've seen this issue on some of my other Xerox machines (not the 8400 specifically). 9 times out of 10 the solution is to update both the printer driver to the newest version, as well as updating Adobe Reader to the newest version.

Here are the links to each:

Hello

This looks like a paper jam in an area where you have not located,like the fuser unit,the image basket etc

To check the fuser unit,Turn off the printer and remove the power cord. Allow the printer to cool off for 30 minutes to an hour before attempting to work with the fuser. The fuser gets very hot while the printer is in use, and you can be burned if you touch it before it cools.

Press the release lever on the side door to open it. Pull down the fuser lever so you have room to grab any jammed paper.

Pull the jammed paper out of the fuser unit. Hold the paper at its lowest point and pull downward. Flip the fuser lever back up and close the side door.

For Paper Jam Under Imaging Units

Lift the latch on the front of the printer to open the top cover of the device. Hold the handle of the imaging unit basket (the gray object with the colored squares on it) and carefully remove the basket from the printer. Remove the jammed paper and then carefully place the imaging unit basket back into its original position.

For Jam at Door B

Open "Door B", located on the right side of the printer. Pull down the paper guide and carefully remove any jammed paper that is behind it. Put the paper guide back into place and close the door.

The problem could also be a Misfeed in One of the Printer Trays,Carefully pull out the tray you were printing from when the jam occurred. Remove the jammed paper and ensure that the remaining sheets of paper are properly loaded--they should be aligned and the guides of the tray should be adjusted to fit the size of the paper. Push tray back into the printer.

you can try other USB cable which length should not be more then 1.5 meter after that if it is not working . replace usb printer card(PCB)

According to the Xerox support website, your printer needs to be serviced by a support technician. Here is a link to the support page.

Copied from another forum:
37,016.4x - PEST_FAULT_HM_CLUTCH_DISCONNECT
PEST - Head maintenance clutch disconnect. The head maintenance clutch is not drawing the expected power from the supply.
1. Run the Head Maintenance Clutch test.
2. Check the Head Maintenance Clutch wiring.
3. Disconnect the Wave Amp signal cable from the left
side of the Electronics Module. If the error code changes, replace the Wave Amp.
4. Replace the head maintenance clutch.

Unless you are skilled at printer repair, it looks like your best course of action is to call a service tech.

go to printer and devices you will see your printer with yellow mark on it right click it the it will ask u to trouble shoot it and then it will ask u to fix it.

Select 'Troubleshooting' and press OK. Select 'Print Quality Problems' and press OK. Press and hold the 'Up Arrow Button', and then press the 'Back Button'. Select 'Turn Jet Substitution Mode Off' and press OK. Note, if jet substitution has not been enabled, the option to turn it off will not be available.
Hope this helps.

hi
you need to replace image belt
this error is only when the image belt is
not been synchronised with the motor of the
drum

There are three possible solutions.
Try running the 'remove print smears' routine from the print quality troubleshooting menu. You may have to run it 5 or 6 times to completely clean the drum.
It may be that the drum maintenance pivot plate is cracked, this causes the plate to press the maintenance kit on to the drum unevenly. You will hear a ripping sound as the paper exits the printer, this is due to it literally ripping the ink off the drum. Being an 8400, if your pivot plate (the assembly that your maintenance kit slides on/in to) is white (off white) in colour, my money is on that being cracked.
The third possibility is that the cam shaft that pushes the pivot plate up to the drum has loose/spinning cams which again, will cause the plate to press unevenly.
Hope this helps.

The most common thing that causes this issue is the drum maintanance cam and or DM pivot plate. I would check the cam like it discribes and also make sure the pivot plate isnt cracked. But really the service not gives you a list of what all needs to be check.

The Xerox website says to take it in to a service center: http://www.support.xerox.com/SRVS/CGI-BIN/WEBCGI.EXE?St=121,E=0000000002388339860,K=7746,Sxi=4,Case=obj(21655)
And here is a link to the documentation http://www.support.xerox.com/support/phaser-8400/documentation/enus.html

> can it be removed ?

Yes, but it's a job best assigned to a qualified printer technician.

The print head causes this error, it will cost you as much as the printer did to replace it.

Make sure it is not on a UPS or sharing power with other print devices as this can also cause the problem.

37,016.4x - PEST_FAULT_HM_CLUTCH_DISCONNECT
PEST - Head maintenance clutch disconnect.
The head maintenance clutch is not drawing the expected power from the supply.

1. Run the Head Maintenance Clutch test.
diagnostics menu -> Exercise Menu -> Activators Menu -> Head Maintenance Clutch
2. Check the Head Maintenance Clutch wiring.
3. Disconnect the Wave Amp signal cable from the left side of the Electronics Module.
If the error code changes, replace the Wave Amp.
4. Replace the head maintenance clutch.

To access the service menu
1. Press OK and Cancel buttons at the same time to display the Service Tools Menu.
2. With the cursor at the top of the Service Tools Menu, press both the Up Arrow
and Down Arrow buttons to display the Hidden Service Menu.
3. Scroll down to Enter Diagnostics and press the OK button

You don't clean the drum. You either need to replace your maintenance kit , or my better guess is your using generic ink sticks and you need to use the sticks xerox makes for the machine.
The problem is that your not getting effective cleaning from you maintanance kit

That error code means that "The Media Drive stalled while engaging headtilt." Check for obstructions in the wiper assy, broken wiper drive belt/gear, etc. Run the Head Maintenance clutch test and wiper drive test.
