Do you know how to get into Simulations i think you may be able to turn accounting mode off!

crum data read trouble

try the finisher area, the f code refers to finisher, otherwise call sharp

enter simulation: pound, interrupt, clear, interrupt, then enter 14, press start,press execute on touch screen, press ca until copier restarts, this is a general clear code, if problem returns you will have a heat problem in the fuser.

IMC pwb communication problem

Check the fuser unit and make sure its installed correctly.

I turned the copier off completely, then turned it back on -- it seemed to resolve the L3-00 issue.

ICU Communication error. Could be a problem with the ICU board or the connection between it and the PCU board. If resetting the machine (main power off and on) does not solve the problem you'll likely need a service call from a copier tech.

An F2 code depending on the secondary code is related to the toner or drum.

F2 00 Toner control sensor open 22 LCC 24v power abnormality
02 Toner motor connector unconnected 50 Non supported option connection (Desk Unit)
31 Process control trouble (Drum surface reflection) 51 Non supported option connection (LCC Unit)
32 Process control trouble (Drum Mark) U7 00 RIC communication trouble
37 Drum marking sensor gain adjustment error U9 00 Operation control communication trouble (ICU)
