Question about Xerox Phaser 7300DN Laser Printer
Message is to re-seat toner, so I remove it and put it back, then it works fine. After a while the same message appears. It is not always the same color. I have removed all Imaging units as well as the fuser and transfer unit, cleaned it all up, and put it back together. Error message continues to pop up from time to time. What is the problem?
The problem is a crazy design in the printer itself! I've now found a reliable fix for this problem which is relatively easy to carry out. You will find the details of how to do it here :

Michel's solution works! I had just bought my 7300N used and everything was great except I kept getting a "cyan toner is unseated" error message. I mean, I would run a test page and then I'd get the error...like every other page. I read through the other suggestions on this page and I tried the "crazy" suggestion of removing the foam on the flag and putting sticky tack on the side of the flags and my problem is solved. I've so far printed multiple pages with no trouble. So go to: http://www.michelsplace.co.uk/xerox-7300.html Michel mentions that the foam you take off is to sound deaden when the flags hit, but I can't hear anything different over the general hum of the printer, so I'm happy.

First thing you should try is the toner cartridge. Second, is to replace the toner Sensor Flags. Thrid, is to replace the Toner Sensor Board. Fourth, is to replace the Engine controller Board.
I usually fix this issue by replacing the Flags... if not I try the Sensor Board (usually doesn't work), and then I replace the Engine Controller Board as a last resort.
Replacing the FLAGS is the BEST solution. I have posted a video tutorial on YouTube on how to replace them. Search for Xerox 7300 Flag replacement or something and you'll see me and my video.
This is a VERY COMMON issue. But is simple to fix/troubleshoot. Good Luck.

We have found that the toner sensor flags are magnetic, and may loos their magnetism over time. When we replaced the sensor flags problem went away. Note flags are located on the top cover assy.

TRY FIRST (Solutions without parts):
1. Toner cartridge sensor is dislodged or stuck. - Reseat and verify movement of the toner cartridge sensor. It may be necessary to remove the flag and sand the pivot shaft and smooth to provide free movement. 2. Toner is packed in the sensor window of the toner cartridge. - Remove toner cartridge and Image unit together as an assembly and tap on a table or counter to clear toner sensor window. 3. toner sensor magnets are not properly seated. - Verify the toner sensor magnets are properly seated in the actuators.
TROUBLESHOOTING TIPS AND HINTS:
Test the toner sensors in service diagnostics. Inspect the Toner Sensor Flags for smooth movement. It may be necessary to remove the flag and sand the pivot shafts smooth to provide free movement. Inspect the wiring harness from the toner sensor board to the engine control board. Use service diagnostics to test the Imaging unit drive motor. Remove the imaging unit keys from the back of the imaging unit and swap the imaging unit and toner with another color.
The problem has been isolated to the Top Cover Inner Frame molding that holds the toner sensor flags for each color. The Top Cover Inner Frame molding has too much variation where the toner sensor flags are seated causing the flags to bounce more than the algorithm can handle. This creates a false error of missing toner cartridges.

So should replacing the sensor board is the best solution?
