Xerox Phaser 8400 Fault 37,008.44:9490

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.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response

Hi there
The onlty thing I can find close to this is.
Acording to the manual its a ink loader error like your loading the wrong type of ink like the puzzles pieces arent matching and hitting the sensor flags right. Yours by the 8 is referring to the black ink. Anyway go to troubleshooting on the control panel. then to service tools. when in service tools press and hold the up arrow while still pressing the up arrow press the down arrow. the display should say hidden menus. go to diagnostic mode press enter go to funtion menu. then go to clear ISC fault and enter. ISC=ink stick count fault. I hope that helps. Just to let you know Ive had nothing but problems with third party ink and once its in the system its hard to get out so I would watch what im doing with my expensive equipment

Hi abonk:
This is your problem.

37,004.4x - PEST_FAULT_RESERVOIR0_HEATER_DISCONNECT
PEST - Reservoir0 Disconnect Reservoir0 is not drawing the expected power from the
supply.
1. Run the printhead Reservoir Heater test.
2. Verify printhead wiring.

Your preheater needs to be replaced.
Xerox Preheater Part # 119641980
This part will have to be replaced by a certified Xerox technician.
Hope this helps

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)

From the service manual:

37,002.4x - PEST_FAULT_JSL_HEATER_DISCONNECT
PEST - Left jetstack disconnect.The left jetstack is not drawing the expected power from
the supply.
1. Run the printhead Left Jetstack Heater test.
2. Verify printhead wiring.

Yes, could be faulty printhead, but could be faulty power supply as well.

I have the full service manual available if you need it. Please take a moment to give this solution a rating of fixya. Thanks!

That code is a jet heater code.The most likely problem is a bad print head, the second most likely bad item is the electronics module that supplies the 40-50 volt source to the print head heater.

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.

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.

The first obvious question is, "Does it have blue ink/wax?" Is it displaying any errors? Have you tried the Xerox support site? They have a fantastic utility that can connect to your printer and diagnose many problems. Here's the URL for the utility: http://www.phasersmart.com/ They also have a wealth of information in their knowledge base. Here's the URL for the support page for the Phaser 8400: http://www.office.xerox.com/printers/color-printers/phaser-8400/sprt-enus.html Did anything happen before the blue quit printing? Have you tried running a cleaning cycle?
