Re: Xerox Phaser 8400 turns on then error...
Yeah it is a hardware issue. The code you are getting relates to the print head tilt and/or side to side movement.
One of 2 things occur to cause that code, these 2 things cause that code about 90 percent of the time.
1. When you remove the ( looking from the front of the machine as refrence) left cover, about 1/2 of the way back, on the bottom portion of the frame, you will see a 1 inch x 1 inch steel pivot block. Often times runoff from the excess tray or seepage down the print head will cause ink to build up in that block. That will not allow the print head to pivot back and forth properly causing that code. There is a spring over that block you need to clip aside to remove the block. It may be very sticky and a little difficult to remove. Channel locking pliers will normally allow you to remove it with some effort. I suggest putting the block in some pretty hot water . It makes the ink softer when hot and easier to remove.
You want to also picko ut all the excess ink in that are that you can to keep the block from gumming up again. Removing the print head is the best way to clean it, but that is pretty challenging if you donr know hte printer.
Now issue 2, is the print head wiper tacking to the print head. If the machine is not powered down properly or is unplug, or a power failure can cause this blade to be in the wrong position and stick to the print head. To access that, you want to remove the right and left covers, and also the ink loader, ( Where you load the ink sticks). It is held in by tabs and 2 plugs. Once you remove that ink loader you have access to the print head drum area. Look between the print head and drum for a pinkish colored blade, Gently detack it from the print head and run the cleaning cycle on the printer when reassambled. The print wiper clutch could be going back causing the blade ot tack, but not as likely.
That code is definatly an issue with print head movement, and most of the time these 2 issues will resolve the problem.
Let me know, There are a couplf of other weird things that can cause this, But I doubt they are an issue.

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.
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
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:
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
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.
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).
