Error 6134 - 1

Hi all,

I'm getting a constant error on my LP7700 which says;

Paper Supply Pressure Change Motor operation error. This happens regardless of which magazine is loaded, and in which section ( B or C ).

It happened after several paper jams on 254 size, there was nothing wrong with the magazine. I've checked the supply section, the advance, exposure and distribution centre, and I can find no slivers of paper or anything else untowards. I'm thinking the motors might have given up, but wondered if anyone else had any other ideas?

Thanks for any help.

This error means the paper supply pressure change sensor does not turn DARK even though a specified time elapsed after starting
the paper supply pressure change motor operation. Check paper supply pressure change sensor, paper supply pressure change motor, printer I/O pcb 1, printer I/O pcb 2, printer control pcb. Open printer door, put magnet on door sensor, go to output check , run paper pressure motor and look what is going on. If motor works look sensor output level.
