    I am having the same problem with mine -- error code 37,004.47
    (remaining number is your page count).
    The reference manual says perform the following tests:
    a. inspect and reseat the printhead interface cable and retest
    b. replace th electronics module and retest
    c. replace the printhead

    Sounds simple, but pricey!

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

Service Light keeps coming on with Code C440. Please advise why?

This is a fuser heat error. Have you performed the reset procedure? If not just turn off the main power, hold the 0 and 8 keys WHILE turning the power back on. Type in 400 then press Start. Set the displayed number to 0 (zero) then hit set or enter.
Power off then back on and the code should be cleared. If it keeps coming back then the fuser unit will need service. Most common fault is the thermistors which are small electonic parts that monitor the temperature of the fuser unit. Pretty in-expensive parts.
Good Luck and Thank You for using Fixya.

2006 2.9 turbo diesel will not start fault codes P1119 P1120 P1640 check engine light stays on cannot locate main relay & computer position any suggestions

dear friend-it is very difficult to explain myself in a text. I would say ignore the fault codes at hand for a while untill we have a definate fault. I would like you to make sure that the battery is fully charged, when you carry out the next exercise. I want you to try and start it with quick start, but please do not crank to long, gentle squirts will do it. If no joy, then we must go live chat- I am sure it will work, but please come back to me
