B180 Ricoh 3245c sc542

Anyone know why we are getting a sc542 code on startup after the machine has been off for a while? Once the code is reset, the machine runs fine for the rest of the day. We have had this problem on a couple different machines. If we replace the fuser this usually cures the problem, but as you know these fusers are very expensive! So whats the root problem?? Why only on cold startup?? Victor

Check your power to the machine from the wall: could be a flaky outlet. Also try moving the machine to a different outlet and make sure it's not plugged into a powerstrip. Do any other strange background codes show in the SMC?

It's the fuser drive clutch, mounted on black PCU drive motor, just try a contact cleaner first off all...

Check stability of line voltage first.

You should also check the fuser lamps, especially the one within the press roller. It's also a common issue that there is paper stucked in the fuser connector that can lead to different sorts of fuser SCs (happens if the customer overlooked a page behind the fuser unit during jam removal).

The fuser unit isn't thar pricey if you use a PM kit plus a fuser belt thermistor (it's not a part of the kit but you should change it if you rebuild/PM a fuser - this thermistor is kind of a metal plate with the thermistor element glued on it and over time the glue gets weak so the element becomes loosen from the plate what causes no SC but wrong readings and too much fuser belt temperature so the belt gets damaged - looks kind of wrinkled then).

Thanks Gift, but I do know enough to check for paper between fuser connectors. Plus after 20 years fixing copiers, I damn well better know what a thermistor is haha... I was looking for something a little more technical.

Pulled out and cleaned the fuser clutch out today... oh yeah that was almost as fun as replacing the seperation roller drive gear in tray 1... ouch!! hope it works!!

[turbojetboy]

Oh yeah T1 gear - that thing is a little plastic bastard - done it once - never again!

Just when you thought the thread was dead... How about the fuser belt... how much fun is replacing that? A claw fell out of socket and damaged it. Figured would be lot cheaper than fuser. Thanks.
