SOURCE: Xerox Phaser 8500DN - no power

1) verify that the power is plugged into a known good power plug in the wall. make sure there is not a surge protector, extension cord connected to it.

2) disconnect any usb and/or ethernet cables.

3) reseat the ram

4) disconnect any optional accessories such as lower trays, hard drives, etc. to isolate any possible items taking down the printer.

SOURCE: my xerox phaser has a blank screen and no green

That sounds like one of two things.
Either the ribbon cable to the screen needs reset, you have to remove 4 screws I believe it is, then unplug everything to that assembly, and re plug them back in.
If that does not repair it, then most likely the electronics module has failed. That is quite expensive to replace.

8560 printer shut itself down and will not true back on


The following lists the chain of events that occur when you turn on a printer. You can follow this list as one means of determining if the printer is operating correctly. The exact chain of events depends upon the last power down condition and where the printer has last determined the printhead is positioned, this is stored in non-volatile RAM. The Checklist is the primary reference for troubleshooting power-up problems.

1. Power cord is plugged in and the power switch is turned on:

2. Power supply senses AC line voltage conditions (110 VAC or 220 VAC)

and enables DC voltages. If an overload occurs, the printer turns off the high voltage DC supplies, causing a "blink" effect on the Control Panel LEDs.

3. BIST test flashes the PE LED very briefly at a fast rate until the end of the

next test.

4. The Boot loader performs CPU initialization and RAM test. It then sends

the boot loader version to the serial port.

5. Power-On Self Test (POST) initializes the Control Panel. The Control

Panel LED turns red, green, orange, and then off. The Control Panel LCD then goes black and then clear. The POST version displays on the LCD

and waits two seconds. During this time the operator can press the Back

button to bypass the remaining POST test.

6. Low level Power-On Self Test (POST) diagnostics are performed. The

Control Panel displays status messages as each sub-test is performed.

This test takes about 8 seconds. All LEDs are off during the test.

If POST diagnostics pass, the Control Panel displays the Xerox logo and turns on the green LED.

If the test detects an error, the error message displays on the LCD and the printer flashes the LEDs with a repeating error code pattern.

7. The VxWorks operating system is initialized and engine code is started.

This takes about 15 seconds. The Xerox logo is displayed.

8. Print Engine Self Test (PEST) diagnostics are then performed. These test

the heaters, clutches, motors and solenoids. As each clutch is tested, you hear clicking with four high tones as each motor is tested. This test takes about 30 seconds.

9. The printer now runs the mechanical initialization. The exact sequence
depends on the initial position of the printhead and wiper assembly.

How to fix problems with electric contact of a xerox phaser 7800dn


Go to the Xerox website and read up on your model. Also see if there is a fuse blown between the power cord and the system itself. Maybe the transformer has died. and needs to be replaced. That happens a lot with devices with 'step down' transformers combined with the electric cord as opposed to transformers built into the device.

Xerox Phaser 8200 goes through post then hangs.


Sounds like a RAM problem. Go to the back of the machine, You will see  2 large, thumb Screws, Twist them about half a turn and remove the main board. Remove and reinsert the memory stick. If that does not fix it the main board or the electronics module has probably failed.
