    I fixed it without replacing anything:



    Hold down the left(back) and right(info) keys while turning on the printer.
    Scroll to NVRAM Access and press OK.
    Scroll to Clear Tech Rep Faults and press OK.
    Scroll to Link Codes 10-348, 10-350 and press OK.
    hit the back arrow to get back to the first menu then exit diagnostics.

Somehow you jarred the fuser. Turn the machine off and reseat the fuser. Open the left side door, there will be 2 thumb screws.
Remove and reseat the fuser, if that doesnt work you have to replace the fuser.

    And you gave me an inappropriate? that is not right nor fair.

    A code 35 is a user problem your codes cleared that.

    What a pathetic way to treat someone who offers help.

  • Rick Kasper Apr 09, 2008

    Thank you for the update. I will keep that one in mind.

    Resetting the NVM sure is a simple way to resolve that one.

    Thanks again.

Phaser 7750 Not Printing, No Error codes, Fuser Wont Warm Up, Wont Detect Open Trays or Doors


It sounds like one of the cover or tray sensors is not working correctly. Check the actuator on the fuser cover, sometimes these break off so the printer thinks the cover is still open. If that seems ok and you have a lower tray deck unplug it to eliminate them as the cause.

I have xerox phaser 7750 by mistake i bought 7760 yellow toner shall install it to 7750


Not yet, check with the supplier and ask if it is compatible with the 7750, if not then exchange the 7760 for a 7750 yellow toner cartridge. Once you open the cartridge the supplier will not exchange.

How do you reset toner counter on phaser 7750? Thanks


On the back of the 7750 toner there is a metal piece you can push in near the end that goes in to the machine first, this will tell the printer that the toner you put in has not been installed until now. I would not suggest doing this unless the toner is full and is using geniune xerox 7750 toner.. If you refill it with generic or non-7750 toner it can damage the machine and will void any warrenty you may have left on the machine.
If you switch machines with the 7750 toner the machine will not know how much toner is remaining in that toner. Xerox changed this method on the 7760 to use a toner chip to fix this.
Hope this helps, thanks

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.

Grainy image quality on my Phaser 7750


Try something, Send a job with 5 pages to it.
Shut the machine off as a page it halfway out of the exit area.. Open the machine and look at the jammed copies. Are they clear in the imaging unit areas but not upon exiting the machine?
If the image is clear around the drums and imaging unit, then the problem would be in the fuser. If the image is grainy and fuzzy in the image area, You could have a bad second BTR roller, the soft black roller on the left side door. One of the developer housings could be bad. You have to remove the imaging units and look in the opening with a flashlight to see if the developer housing brush is thick on the developer roll.
Could have a bad transfer belt or one of the color housings could be bad.
Less likely is a bad laser. But have you taken the wand that is on the front cover and cleaned the laser exposure slots?

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.
