[danteinferno]

well i have a irc4080 copier, i start to have color displacement so to fix it, i did this.
1. first clear the ITB (gears, rollers, inside the ITB) then the gears inside the copier.
2. make a auto graduation,(FULL)mm and print the PG6 and PG10
after this i saw i have a displasment in the vertical guides but the horizontal where ok.
3. then I check out the drums and their were ok, even open the drums to check out.
4. i made a DC-CON clear,, after this unplug, for 5 seconds,
5 after this made a auto grad 3 times, and a PG6 and PG10
now the horizontal are wrong but the vertical are ok..

so what can I do rigth now.?

where after searching the web i found a great solution to my problem to fix it, after I did a D-CON Clear i didnt put the original values of the lasers,, so
after i put the original values. let the machine for 1 hour OFF.. then the problem was solve.

Lucky---------there is a standard procedure before any DCON/RCON/ or MN-CON CLEAR---
U need to print out the P PRINT settings-enter service mode>COPIER > FUNCTION > MISC-P > P-PRINT

Advise>>> get a manual on your product

a dcon clear for this problem will not last. Its easier to go into level 2 and clear the registration for a band aid fix. Better ready a ITB rebuild. There is also an updated cover kit to help prevent smears and drag on an aged belt. fm3-5438 its a low cost to add this modification.

Personaly, i think the cover kit is crap. The real problem is the secondary inner transfer roller bushing. Soil accumulating inside makes the inner tr.roller turn heavy, causing the belt to bend and touch the cover. Also a dirty drive roller and inner belt makes the movement a little less constant, with stutters, also causing the belt to touch the cover.

I just do a proper clean of the drive roller and transfer roller bushings. New belt and presto... replace the primary tr. rollers after 500k and inner tr. roller when damaged.

I throw the big ITB metal cover in the garbage> and use this technique below as shown= no dirty streaks or smudges

note: make sure to ground that other end of varistor/

Re: canon IRC4080 color displacement (another post)

The main reason for this fault is the leaking black drum unit, ALWAYS replace the black drum before they get to 200% & you will never or rarely get this problem of the ITB slipping.

Strange that the colour drums don't leak much at all even if they are well used over 350%!?

Same on the CLC3200 & CLC5151/IRC4080 etc

I have always believed that the % Reading for those Black Drums on both series has a calculation glitch that Canon never addressed/ or is it the carrier to toner ratio that brakes down faster

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 ?
