Check the left side door assy where the fuser is located, on the door near teh top towards the rear of teh printer there should be a piece that sticks out which will close a interlock swith when closed. It may be black or same color as teh covers. If this is broken off it will cause the problem you describe. Easy way to check is to use a screwdriver to push in on the interlock to close it and see if the problem goes away.

Error u26 phaser 7300


U26 is Yellow Image Unit failure. It may be that the contacts are dirty - spilled toner?? Give it all a thorough clean, especially where the electrical contacts are - if still no luck, then a new yellow IU should solve the issue.

Xerox phaser 6360 laser failure code 07


The most likely cause here is the laser unit, check all connections to the laser unit and cycle the power (turn the machine off and on) if error continues replace the laser unit. You can buy a replacement for $350 new or $225 refurb. Part# 062K17233. Installation isn't very simple, so if you aren't a technician you may want to bring it to one. Good luck

11 error


You have not provided a lot of information here....

But my best guess is that you have a Laser Scanner motor failure...

If the error repeats 3 times in a row, the device will lock out, and need resetting by a technician.

Safety note
- If you are not competent at fixing electronic equipment, you should get a qualified technician to fix this

Check the cables to the Laser Scanner and reseat them.

Phaser 7700GX getting yellow bar down the side of page on all prints


Try cleaning the Laser Unit for Yellow. Try replacing the Imaging Unit for Yellow, or simply take it out and move it to another color.... if the problem occurs on the the other color then it is definitely your Imaging Unit. One of those two is probably causing your issue.

Good Luck.

Xerox Phaser 7750


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.

Error 10 laser unit failure on phaser 7700GX


That requires the replacement of either the ROS ( laser) assembly or the MCU board. I have seen both cause that code and indicate the laser has failed.
ROS is the laser assembly.
MCU board may not be detecting the ROS.
It is possible the connector that runs from the ROS to the board is loose, you may want to disconnect and reconnect that.
If the ROS is bad, you also have to have a laptop to connect to the machine to align the colors. That is called the regicon adjustment.
