Question about Xerox Phaser 7760DN Laser Printer

1 Answer

Hi, Having a problem with our Werox Phaser 7760 - there seems to be a white line on the black running the length of the sheet - have changed the toner, transfer roller and imaging unit to no effect. When you take out the imaging unit and shine a torch into the machine, there seems to be some sort of magnetized roller and you can see a mark running round it at the position of the mark on the sheet. Can this roller be removed or cleaned or something? Thanks for any help in advance. Lee

If the white line only appears on a signle color (black) then it has to be either the image unit, laser, or developer. You can try cleaning the top of the laser using the arm located in the front door, because toner ofter spills onto the laser window causing white streaks. However, Judging by your desription the part you are referring to is the developer. You can attempt to clean it if you can reach it or replace it. The assembly is part# 802K60191 and you must also purchase the devloper charge (black) part# 604K22550. This isn't a very easy fix, so if you are not very technical you may want to bring it to a copier technician. If you wish to fix it yourself and order from ItemIncOnline.com they will send you instructions with it. If you are still confused call 1-800-367-4836 (free tech advice, specialize in this machine) Hope this helps. - Steven

The accumulator belt on my 7760 phaser is giving a past end of life message. How can I find out how many copies it has remaining?


Try printing the full status sheet. If you print out all the setting it should cover all the information you need to make your judgement.
Good luck.

Xerox phaser 7760 saying "black ATC sensor failure - code 009-380", i changed developer and xerox phaser 7760 saying "black ATC sensor failure - code 009-380", i changed developer and xerox phaser 776


When you have a sensor failure, you need to replace the black ATC sensor and recalibrate it. Another reason for sensor failure is you are not getting toner moved down to mix with the developer...the toner tube/auger spring could be clogged up or not functioning.

Also if you changed the developer housing when you changed the developer, you need to change the value to the new sensor # that comes with the housing.

The black image unit of your machine should be replaced soon. It is a maintenance item and is very easy to change. They cost about $350 new, but you can buy one much cheaper rebuilt. Here is a video I made to help explain what it is you need to change and how to do it. Good luck
