[Dead] LD040 - False Jam at A, C, & Z

[Ricoh-ono]

I have a LD040 that seems to be kicking my a$$. It has a false jam message at A,C, & Z that won't clear. Pulled everything apart couldn't find anything. Ran input checks with no luck. Reset all connections to IOB and BICU boards. Engine memory clear. Replaced sensors and door switches. Replaced IOB and PSU. No luck.

Anyone see this?

Tech Bulletin that may be related, but says for A,B and C jams.

Thanks teebee1234. I read this bulletin and replaced this sensor along with others . My problem, although similar, is different in the fact that it displays A,C,&Z.

One other point that I forgot to mention was in the brief moment when I toggle between copier and printer, all the drawers display European sizes.

**UPDATE**

Replaced BICU NVRAM. Problem fixed.
