HP LJ 500 MFP M525 – light print, screen is freezing
The copy quality is poor, and the screen is freezing while selecting print options.
How the printer was repaired:
The scans/copies are faded from both the ADF and flatbed. I cleaned glass which did not resolve the issue. This printer requires a new image flatbed scanner unit which is half the cost, if not more than the cost of the printer. This printer may need a DC Controller also, which is another expensive part.
The freezing screen could be due to the hard drive, formatter/main board, and or control panel. Both the High Voltage Power Supply and Low Voltage Power Supply would be in question as well. This is all due to bad power.
