    I can't seem to get to the Service Diagnostics. Back arrow and "i" have to be pressed simultaneously?

    All i managed to see when i hit Back arrow was the word "Null".

Reset the Tray 2 feed counter within Service Diagnostics as follows:
1. Enter Service Diagnostics (back arrow botton with the "i" button soon as you turn it on) and scroll to NVRAM Access and press OK
2. Scroll to Reset CRU Life Counters and press OK. The display will show the status of all CRUs. Press OK until the Reset Counters menu is displayed.
3. in the Reset Counters menu select Yes and press OK.
4. Scroll to Tray 2 and press OK.
5. Exit diagnostics.

That's what worked for me I called a company called Iteminc they gave me the instructions and they told me to :Replace the tray 2 pick, feed and separate rollers before it starts jamming soon. www.iteminc.com is their website good luck give them a call if it does not work.

Hi i got xerox phaser 7750 and i have error code


Cheap fix : reset the Developer Life Count in the Service
Tools menu. Hold down the back ARROW key with the "i" them with your other hand turn on the machine.


Expensive fix : What has happen is that the developers have come to the end of the life and once it gets to a certain page count it will print out no more until you have replace the developers. One thing xerox forgot to do is reset the engine control board too for this machine. So you might need a new engine cotrol board too.
Procedure

1. Replace the Developer
2. After the Developer has been replaced, reset the Developer Life Count in the Service
Tools menu.
NOTE: It is recommended that all the Developers and Beads be replaced at one time rather
than on sccessive visits.

Good luck.

I have a xerox 7750, error code 9-913


This problem occurs when you buy the wrong image unit.
The contact chip that is located at the bottom of the orange plastic is not for the machine. Replace it with 7750 image unit and that should fix your problem. Black is fault 9-910 cyan fault : 9-911 magenta fault: 9-912 yellor 9-913.

There is a motor in the laser called the polyogon motor, It turns the mirrors in the laser.
It most likely is not starting fast enough.The laser isnt that hard to remove. But if it has failed, it is pretty expensive.
Let me know if you want to attempt to pull it.

PRINTING ERROR


> Home > Support & Drivers > Knowledge Base

Solution --> ERROR 0082" name="Note" /> Phaser 790 / DocuColor 2006 Printer's: Cancel print job and cycle the printer's power

  • On the printer's Control Panel, press the Cancel Key (12 KB).
    Note: The READY message may only appear briefly. You may need to keep repeatedly pushing the CANCEL key.
  • If the error message persists, turn the printer off for at least 30 seconds and remove the computer interface to the printer (17 KB) before turning the printer back on.
  • Use the menu keys to perform a front panel reset (under RESETS menu).
  • If the printer redisplays the error message upon reboot, a file is likely STUCK at the front of the print queue. Use the front panel RESETS menu to CLEAR LOGS AND QUEUES, which will delete all print jobs in the printer's disk spool.
    Note: The READY message may only appear briefly. You may need to keep repeatedly pushing the MENU key to gain access to the front panel menu.
  • If the front panel menus can not be accessed turn the printer off for 30 seconds and then turn the printer back on.
  • If it is known which print job was last sent to the printer, try to reprint the last job spooled, which may be the cause of the error. Step 4 on clearing logs and queues may need to be repeated to eliminate the crashing job.
Note: Most XX82 or XX1E front panel error messages are NOT hardware related, but caused by a specific print job or application.
