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?

Replacing the pring head.
1. Remove the side covers.
2. Remove the ink loader assembly. There are 2 connectors on the ink loader. SO remove it slowly.
3. Remove the spring guides on the print head. One on each side, Held in my one torx screw.
4. Remove the spring bracked assembly on the left side of the printer, it puts pressure on the XY axis motor to position the print head. Just pop it off and position it up and to the left of the bracket.
5. Remove the steel square block on the left bottom side of the frame.
6. Unplug the harness and ribbon cables and then from the back of the printer, remove the print head, be careful not to hit the drum.
Install the print head, the ribbon cables are somewhat difficult to plug back in, Just be patient. and make sure they are conneted firmly. Also when replacing the cables and harness, be sure they are routed corectly so the print head does not get bound on them.
Set the print head into position and install the steel block, then the spring bracket on the XY motor, then the spring brackets in the proper positions. Dont forget to put that spring bracket back on, It is easy to over look.
Make sure all things are plugged in on the print head.
Next reinstall the ink loader, make sure all connectors are connected.
Install the covers and you are done.
Take your time, probably should take about an hour. Just to it carefully and methodically.

This is a print head position issue.

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.

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 technical error message means:
The Printhead Left jetstack heater is not drawing the expected power from the power supply.

Possible solutions:
1) Make sure the AC plug is plugged into the wall and not a UPS or surge protector. Other things such as another printer, coffee maker or other electrical devices on the same circuit could cause a sag in AC demand from the Phaser, causing it to fail it's PEST (Print Engine Self Test).

2) Verify that the wall outlet's circuit is capable of delivering the correct amount of current to the Phaser, if it does, check how many other electrical devices (aka a desklamp, radio, etc.) are on the circuit.

3) If it's out of warranty, reseat the cables from the Printhead to the Electronics Module. If it's in warranty, place a service call on the unit.
