Re: canon IRC4080 color displacement (another post)

I have a case with this modification. I have put the varistor inside the metal part.
Accidentally saw (from the rear side) that the film was discharging to my finger while machine was printing.
So I put a little cable which is touching film on one side and the metal shaft on the other side.
How come this electrical discharge ?

never seen that issue/
just make sure u use a metal screw on one end/ do not use a plastic screw> needs to be grounded
or it will throw >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

E003 0001, E004 0101/ 0401, or E007 0201 errors/or
Jam Code FF90 ----------------

varistor helps to dissipate charges built up in the ITB assembly.

I did put a metal screw. It has fixed the problem. No errors whatsoever.

I was after a magenta leak on the entire page when I saw the discharge in my finger.

I don't know why on some drums (magenta only) - developer looses its magnetic power and starts to overflow.

overtoning on magenta is most likely due to heavy usage and then things get thrown out of whack. Ive seen this on some HP printers too.

One point to note:
for 5180 series only
did u ever see that old 2009 ITB update for plate on 5180 series / they had a retro fit to change the gap
to prevent blurred or smeared images ??? useful only as a temp fix on older ITB Units- and ones that have never been replaced from 2009----------------------------
ITB_TP08 285b.pdf


the newer (FM2-5365-010) ITB Units in 2009 was supposed to fix this issue/ but it doesn't/never has paned out for customers who use this printer as a printing press


like I said before/ it's all about paper type + % coverage= eventually blurred or smeared images/


the varistor & plate removal has prevented about 60/70% recalls on CQ Plate issues /
u ust need to tell customer to be careful reaching in to remove jam paper underneath ITB

Yeah I had that retro fit done in 2 units. A lot of little jingles - not a life changer though.


I will try to shoot a video of the electrical discharge on my finger just for fun.

check printer ground at outlet

GROUND TO NEUTRAL= 0v/0.5v Max

Re: canon IRC4080 color displacement (another post)

I suspected that too. Very old building. Crappy electrical wiring. Best combination.
