I have xerox phaser 8400 : when i turn it on it says : service needed fault 37 002 47:115353\r\ncould anyone help for that . thanks

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.

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.

You have a failed resivor heater in your print-head, your print-head will need to be replaced, unfortunately more expensive (800$) then buying a new Xerox Phaser 8550dn from Tiger Direct. ($750 ish)

No, it will not work because the chip (CRUM) is not compatable.

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.

1, The NVRam memory is corrupted.
2, A jet heater is not working
3. the electronics module is bad.

Parts possibly bad are the NVM, the Print Head or the Electronics module.
Hard without a manual to determine, all are expensive.

Sadly that is not good.That normally is one of the heaters in the print head has failed not warming up enough to allow the ink to remain liquid. It frequently is the result of a failure of the electronics module, none of the most likely problems is a cheap fix. I will give you the list of most probable causes.
Wish I had a more hopeful answer.


PARTS:Parts are listed in the order of highest probability for repair.
NUMBER QTY DESCRIPTION
119649580 1 *ELECTRONICS MODULE (STRIPPED)

671529180 1 I/O BOARD

650430300 1 *PRINTHEAD ASSEMBLY
The electronics module. Listed as stripped, means it comes without the ram and nvm boards. When that fails it is a portion of that module that supplies the heater voltage. I think its a 50 volt source off hand.
