Question about Xerox Phaser 7750DN Laser Printer
The fuser will not heat up, the displays stays in the "Warming up fuser" text but fuser never heats up...
This might be a bad main Image Processor (650-4307-00) board. We can isolate it by printing an internal test print.
You can power up the unit in diags (hold "back" & "info" buttons while powering up) Go to "Built in Test Prints" and try to print the "Grid 1 Dot Pattern"
If you print, then it's proven...
If not, then you will get an error that will allow further troubleshooting.
