[CQ] Black shade on printouts

[icopier]

Hi guys,
I have this issue that there is a black shade on the paper. Was fine last week but after 1 week (machine kept on) but no print/copy jobs, the printouts became this (see attached).
Previously I had the same issue on another IR Adv C5035 but was resolved by clearing the DC-Con and full adjustment.
This time it did not work. I suspect the DC con was not cleared successfully. (I did a R-Con & restarted the machine,the settings still remained)

Any advice on this black shading issue or DC-Con clearing?

Thanks and hope to hear from you guys again.

Re: Black shade on printouts

Looking at the sample as well as what Teckat has asked I would also be interested in looking at the fuser cleaning and drum life. The sample has regular lines in it which to me sugests a possible mechanical cause, where as the DC-Con (to me) would create an unbroken background.

First thing would be to take a look at single colour test prints to see if it is repeated on those as well.

Color seems okie with PG10. but still have the black shade.
And i am aware that the fuser film has a small tear but the customer prints only b/w so it is fine for them.
Crititcal issue would be the black shade

Your posted copy shows background in the BLANK AREAS/ Non-Image area.

Did u check the single color test prints ?
Does the pg10 have background in Non-Image areas ?

Have u checked a Black Drum Grounding Or Bias issue_?

the PG10 has black background in the non-image area as well.
Single color has black background in the non-image area too.

May I know how can i check the black drum grounding?
thanks for your guidance.

U could also have a Black Developer Assembly
issue.

HVT 2 provides the primary charge for the black drum.
C5030 - C5035 use GPR-31 Drums. Black Drum part number 2778B004BA. Color Drum Unit 2777B004BA.

U should back-up those DCON\RCON settings before a clear,
Then put them back in.
If u don't, I put the settings back to factory.
Unless u put back the sheet settings.

To BACKUP Reader Controller data prior to clearing or replacement:
Enter Service Mode Level 2 > Copier > Function > System >< RSRAMBUP >
Highlight RSRAMBUP and select OK, item will indicate "Active" and end with "OK." At this point, it's now ok to replace or clear the Reader Controller.
:-))
To RESTORE Reader Controller data:
Enter Service Mode Level 2 > Copier > Function > System >< RSRAMRES >
Highlight RSRAMRES and select OK, item will indicate "Active" and end with "OK." At this point, Reader Controller Data has been restored.

To BACKUP DC Controller data prior to clearing or replacement:
Enter Service Mode Level 2 > Copier > Function > System >< DSRAMBUP>
Highlight DSRAMBUP and select OK, item will indicate "Active" and end with "OK." At this point, it's now ok to replace or clear the DC Controller.

Very valuable information!
I am not sure, but it really seems to have something strange on clearing the DC-con and R-con. the "Ok" buttons pops up almost instant and all the settings still remains after restarting.
I found some of the error prints in my car, and attached them.
Have you encounter them before?

After changing all the parts mentioned, the problem still remains.

Today i replaced the black drum and it work! I took the faulty black drum back to factory to try again on another machine...It work flawlessly as well.
Both are brand new drums.

Un-explainable x-files...

Nevertheless, thanks all for the valuable input.
