Xerox 8400 error code 37,063.45

It can be fixed, but only by a Xerox authorised service centre. Xerox website tells you to turn it off and book it in for a service. Be prepared to pay a call out fee before hand. Here's the reference link for your error from Xerox website.

Try this:

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:

• Go to the Find an Authorized Xerox Service Provider near you web site
• Contact the Local Xerox Support Center for service

If using the local service provider website, please perform the following steps:

1. Enter your zip code in the space provided.


2. Choose a mileage distance. The search will locate a Service Provider within the specified range if available.


3. Click Go. The web site will return a list of Authorized Service Providers (ASP) with their company name, address, phone number, and fax number.

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

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

From the service manual:

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.

I have the full service manual available should you need it. Thanks and please take a moment to rate this solution as fixya.

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.

That is related to the print head heating. Normally one of the print head heaters fails which requires replacement of the print head. The other item I have seen fail and cause that code is the electronics module. Both are very expensive.

well..it's a system error code..is this an older machine, by chance?

I have the same problem. Xerox says they need to send someone out and can not tell me what this code means.

Prior to the error I have having light streaking on the page. Took everything apart and cleaned and it worked OK for 2 days then returned to streaks.

If anyone knows what to look for please offer assistance.
