Make sure the printer is plugged directly into the wall outlet and not into a surge protector or multi-outlet strip. These devices will not let enough power get to the machine for proper operation, resulting in 37 series errors.

The Fault you describe relates to the preheater being disconnected or no voltage getting to the preheater. Check the connections.

Printer not turn off

It sounds like a driver problem. Unplug the printer from the power and computer. Uninstall the drivers completely and then use the original disc that came with the printer to reinstall everything. Leave on automatic updating.

Screen will not come on when trying to power it up. the power button blinks red 7 times, then pauses, then blinks 7 more times. it will repeat this process over and over. t.v. will not come!!!!

The blinking seven times is a fault code to locate which area of the TV has developed a problem, this is a protection mode to prevent further damage. I would need to know what model of TV you have to try & give you an idea of which section of the TV is at fault. This could be a power start up or scanning fault.

Fault code 37,004.40:49612

Check you power coming in to the unit. If you are using a surge protector or UPS unit, Plug the unit into the wall and power up the printer. If that does not work, then:
PEST Fault 37,004.40: xxx
Printhead reservoir 0 disconnect:
Reservoir is not drawing the expected power from the power supply.
Service manaul states the the printhead needs to be replaced.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Error in xerox phaser 8400

37,004.40: PEST - Printhead Reservoir 0 disconnect. Reservoir 0 is not drawing
the expected power from the supply.

One of the printhead cables may have come partially unplugged. Also, an ink spill on the circuit board could lead to this problem.

Fault message comes up after the printer is powered on

That is a print head fault. Most likely the print head itself has failed.
