Hp 9055mfp front door's open error msg

[dkirie]

Hi, everybody.

There's a message on the screen - "close front door". All doors are closed. Input checks 25-2, 25-3, 25-7 gives LOW level, i.e. closed. But 25-4 (Front door open/close detection SW signal) is HIGH. Can anybody explain, what is it?

Sounds like the front doors aren't latched. Either that, or the sensor is malfunctioning.

Doors are latched for sure. I suspect +24V distribution now. Have no block diagrams, so in a trouble. Thanks
