Hi all, am looking for some advice on this m/c,the fault is the paper jams at the registration rollers,the rollers dont turn at all,I have checked the motor by plugging it into the connector for the feed motor on the MPU board and using output mode and it turns (albeit in reverse),it doesnt turn at all in output when plugged into its own connector,I suspect it may be the MPU board at fault but as this unit costs over £1,000 I would appreciate any feedback before ordering,thanks in advance.
