Copy issues - yellow background on copies

[Ronald Canon]

Hello everyone, i have a problem whit an irc5185 the copies present yellow background but only sometimes this problem appears, all the prints until now are ok so i think this is a ccd unit's problem or maybe the scanlamp, what can you tell me about it? Thanks a lot you guys...

Re: Copy issues - yellow background on copies

if it happens on prints as well then I'd point at the yellow drum. If only on copies then dirty CCD or it's blown. Does it do shadows or just lines?

Yes, i clean all the mirrors the ccd unit and the scanlamp too, the prints are ok so i don't think is the drum, the problem is : All background except the image is yellow, i want to share the samples but i can't upload the files...

Re: Copy issues - yellow background on copies

if it's not on prints then it's a scanner issue. Couple things that I can see.

First check the ribbon cabling from the Reader Controller to the Interface PCB for any damage or a lose connection ( J202 / J203 ). If the ribbon cabling checks out fine suspect a faulty Interface PCB Assembly ( FM2-0036-040 ).

Tried replacing the Dc Controller 1, Dc Controller 2, Main controller, and the yellow laser. This did not help. Replaced the lower of the 2 Main controller Sub EF-A-pcbs. This resolved the issue.

MAIN CONT. PCB ASSY, PDRM-EF-A FM2-7429-000

Run an rcon clear and then perform a ccd-adj and see if that helps. The obligatory p-print before all adjustments goes without saying.

WELL, MY FRIEND IS ALSO A TECHNICIAN AND HE MADE THE AUTO GRADIATON ADJUSTMENT TWO MONTHS AGO.

THAT COULD THE PROBLEM? PLEASE TELL MORE ABOUT IT. THANK YOU TECKAT.



I DID THE RCON CLEAR AFTER THE PROPPER REVISION WAS MADE (THANK YOU northernlife) AND UNTIL NOW THE PROBLEM HAS SOLVED. I'M GOING TO SEE IF THE PROBLEM APPEARS AGAIN TO MAKE ANOTHER VISIT TO THE CLIENT.

THANK YOU GUYS FOR THE HELP.......

I hope u had a PPRINT to put back the original RCON settingd afyrt the clear ?

U need to do AUTO CALIBRATION - at least every two days\ that is a customer requirment to learn gor both PRINTER & FIERY (if attached)

Re: Copy issues - yellow background on copies

auto color mismatch and a full auto grad are there for a reason, because they work. It's part of my call procedure to do both at every call. I also train my clients to do it before they do a large run to "ensure optimal copy quality"

Re: Copy issues - yellow background on copies

auto gradation should be done every morning before they start running the machine period and as northernlife pointed out before they run any long jobs.

I have had to change drums due to backgrounding. Usually happens past the normal drum life.
In Service Mode under Display>Misc shows the percentages of drum life.
