Hello community,
after a fuser error 50.2 I replaced the fuser with a new one. The error switched to 50.4, which appears shortly after powering up. I have followed the information from the thread from DAN-Kov here: https://h30434.www3.hp.com/t5/Printing-Errors-or-Lights-Stuck-Print-Jobs/laserjet-pro-200-MFP-m276nw-50-4-50-7-fuser-errors-with-a/m-p/9167153.
The photorelay on board RM1-8705 gives a voltage of 3.00V in obstructed state.
The second photorelay on that board for the backside panel detection gives 3.30 V obstructed and 0.13V unobstructed. I am in doubt, if one sensor RPI-579 is the cause,
Does anybody know which voltages are expected at the different test points of the board?
Best Regards
