37,004.4x - PEST_FAULT_RESERVOIR0_HEATER_DISCONNECT PEST - Reservoir 0 Disconnect Reservoir 0 is not drawing the expected power from the supply. 1. Run the printhead Reservoir Heater test. 2. Verify printhead wiring.
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.
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
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.
I have been hesitating on answering this because people hang me out to dry on phaser printers when I give them good info. But here goes.
What you can try is go to the back of the machine, whre eh on off switch is located. there are 2 larger thumb screws you twist to align with the back frame. That holds the main board in place, Losten them, remove the main board, reseat the RAM memory into its slots, re insert the main board and try turning it on. If that doesn't work the most likely problem, ( 90 % likely) is the electronics module. And I am sure you did not pay as much for the machine as an electronics module would cost, Generally they are over $1000. Best price.
37,002.47: PEST Error - Left jetstack disconnect. The left jetstack is not drawing the expected power from the supply.
Try turning the printer off for 10 minutes or so, then turn back on. If the error happens again you will need to have the printhead replaced.
Make sure the printer is plugged directly into a wall outlet, not a surge protector or multi-outlet strip. These devices will not let enough power reach the machine, causing most of the 37 series of errors.
Look at the posts on fixyourownprinter.com. I read through some a few days ago and there was a lot of information about your problem. Most were cautioning about using generic ink in that printer was a problem because of melting temperatures. Good luck
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:
They also have a wealth of information in their knowledge base. Here's the URL for the support page for the Phaser 8400:
Did anything happen before the blue quit printing?
Have you tried running a cleaning cycle?
