**lukeh** · 06-30-2014

hi all

was wondering if anyone has come across a simlar issue i am having on a mpc 2000 it jams intermitantly either before or after registration
but it doesnt record it on the smc only sc/jam counter that increases is the jam at power on any ideas or answer to this issue will be great thanks
i was thinking could it be the front door switches ? what does jam at power on mean?

It means that a piece of paper was detected in the paper path when the machine was turned or when a door was closed. If the machine has am external finisher, the usual cause is the jam door switches on the bridge unit. Replace the switches and make sure that all firmware is up to date.

I think it was 4 years ago. MP C2000 with intermittend jams. Turned out to be a bad push-switch for the waste toner container. These jams also do not show up on the jam history.

Possibly the same push switches used on the bridge unit?

If the machine has a bridge unit installed check the bridge unit push switch as this is a known issue on them. At power on usually has something to do with a door switch or cover that is not making proper contact.

Also make sure the Engine firmware is up to date. one of the new firmware versions said something about changing the timing to reduce those bridge switch power on jams.

I never replace the push switches, I have always taken them apart and cleaned the grease from the contacts with alcohol, this method has never let me down
