Re: Xerox 8400 dp
That specific code is related to the print head moving slowly from the park to the use position.
If you remove the covers you want to check these things in order as most likly causes.
1. looking at the printer from the front, on the left side, there is a steel block lower on the machine about mid way back. See if there is any ink in it. If there is you have to remove that block and clean it.
2. Check to see if any of the print head harnesses are causing the print head to bind.
3.The cleaning blade may be stuck to the print head if the printer was not shut down properly.
·The printer was powered off in the middle of a cleaning cycle and the wiper has frozen to the printhead.
·A Drum Maintenance Camshaft lobe is broken and holding the Maintenance Kit?s oil roller against the drum when it should be retracted to its home position.
·Process gearbox not being aligned correctly as described in the service manual and in Service Bulletin 714.
·A broken left or right printhead restraint.
·Ink spilled in the roll block preventing the printhead from tilting forwards/backwards or from traveling left/right.
·Ink or other debris under the printhead that do not allow it to fully tilt backwards or forward.
·The printhead wiper assembly not being aligned correctly or ink spilled in the wiper tracks on either side of the printer.
·The printhead tilt gear not being homed correctly.
·The X-axis motor nose cone not being installed correctly.
·The ferrite torrid on the printhead interface cable has slipped behind the printhead causing the printhead to bind when it tilts backwards.
·The black plastic shroud on the back of the printhead is snapped off and binding the printhead when it tilts back.Additionally

It means the printhead is stuck in the tilt position by the tilt arms. If the process motor gearbox is out of sync, it'll cause this error.
Steps to resolve: Reboot the printer. Verify the lock arms rotate correctly. Check for spilled ink around the printhead (did you move it without waiting for it to cool down?) Check the process motor gears for damage. Make sure they're aligned and homed correctly. Repeat for process gear box, process shaft, and drive module shaft. Verify the headtilt gear will engage. From there, run the Tilt Axis Drive test, Process Motor test, Head Maintenance Clutch test (replace clutch if failed), and Wiper drive test (replace wiper drive system if failed)

Tip: The max point reward for answering a question is 15.
The printer has encountered an error state without the benefit of a
code. Turn the printer off for 30 seconds, then power back on.
If the Printer Error message returns, press the i button on the
printer's front panel. The actual error or fault number should be
displayed. Note the error or message and search the knowledge base for
the error.
Also:
Based on the problem description provided, we have determined that your printer needs service.
Please turn your printer off and use one of the methods below to make arrangements for service:
When you power on the unit it goes through a series of tests to determine that the correct voltage is going to each system within the phaser. The error code you've provided implies a Preheater error 37,008.44
AC power supplied by power sources such as uninterruptible power supplies (UPSs) or DC-to-AC inverter systems may not supply correct voltage to properly power up the printer. Likewise, other devices sharing the same AC
circuit can cause AC voltage sags that cause the printer to fail its AC heater PEST tests (Print Engine Self Test).
My first suggestion is to remove any other devices from the electrical outlet the printer is on, and then power it on.
If the error persists, you've got a hardware failure internally and would need to replace the preheater and deskkew assembley, Xerox PN 119641980
By the way, the last 4 digits in your error code are the current page count of your printer. This number is relatively low and thus it begs the question is the printer still under warranty? The part in question is about $110, however installing it will not be an easy task if you've never taken a Phaser 8400 apart or you do not have a service manual.
My suggestion, if the machine is out of warranty, is that you bring it to a qualified repair technician for service, unless you feel comfortable doing the repair yourself.
best of luck in any regard
The majority of the time that code means the print head has failed. That is a print head heater error. You can find some places that sell print heads for about $150 , you would have to google the model number for that. Xerox would charge $750 for a new print head, uninstalled.
That is a print head tilt error. Either the print head pivot block is contaminated with ink or the wiper blade is tacked to the print head.
Let me know if you want to try to resolve it yourself, I will send you directions.
TRY FIRST (Solutions without parts): 1. Check that the wipe mechanism has homed. 2. Check the printhead position and verify that it has initialized properly / manually home the printhead and power cycle the printers power and check for the error to return. If not then the error was most likely due to non-process function (something out of sequence).
Part likely to be the cause: GEARBOX AND MOTOR,PROCESS DRIVE - PL 4.0, Item 14.
