Re: image runner advance c7260

ok, I think we can safely write off the E13 since its a WTB full error and your symptoms are dumping toner into the WTB.

so lets start at the top of the E20 error.

what is the DENS value? (Copier>display>dens>dens-s)

have YOU checked the loom connecting the patch sensor to the Drum ITB driver?

is the ITB free of dirt/sratches?

have you checked the actuation of the atch sensor cover?

is the laser dustproof glass free of dirt?

are you on the latest firmware?

Re: image runner advance c7260

Hi firmware is up to date ..loom checked ...itb good...dens are yellow +0.00% magenta -0.23% cyan -0.29% black -0.17%...just to add counts are 40k bk and 21k color ..black toner changed x2 and colors x3 going off p print

40k blk and 2 toners used???????? I can't recall of the top of my head but that doesn't sound right.

ok follow up questions then:

are you 100% positive that the users are only printed office documents and not full bleep images?

are Genuine Canon OEM toners and parts in use?

Re: image runner advance c7260

Original toner is being used and machine in normal office ..its a strange one !!

Re: image runner advance c7260

what about the drum surface?

more specifically, the drum cleaning.

in theory if the charge isn't being removed properly it could lead to an overtone on the ITB which could account for the effective toner dump into the WTB.

worth checking out if nothing else, make sure there's no grime on it.

Re: image runner advance c7260

hi all...just updating thread...went out to machine with canon today ..only fault found was that belt wouldnt perform set up...only done 14%..canon tech said had seen before on new belt..maybe whats causing more toner usage as machine doing more gradations..thanks for all replys as usual
