Hey, if you can adjust the coro wires on a NP 6035 you're a freaking miracle worker. Since the 6035 uses charge rollers instead of wires.

When you replace the drum on a 6035 you need to enter the "pri" and "IP_ofst" printed on the drum lable into the service mode *3*. (service mode is entered by opening the door, and poking a paperclip into the tiny hole in the front cover till you see a $ sign on the display. ) After entering those values you need to run APVC_MR in service mode *4*. If the copy quality is still off (and you have performed the obvious maintenance items like cleaned the glass and the mirrors) then go back into service mode *3* and adjust the bias. Factory setting for the bias is "0" but you may need to adjust it to -10 or lower. DO NOT adjust the lamp, PRI of light_5 for copy quality and reset those to the door or drum specs if they have been changed.

First of all did you clean the optic? How about did you replace all of the corona wires? Also, did you clean the scanning lamp as well? Also when you had fitted the new drum, did you use a brand new one or a different one, did you clean the drum with rubbing alc. If all that was done, do a "AE" adjustment in service mode using white paper on the copy board glass. Also, go to the addictional funcation mode and go to expossure adjustment and make it lighter. Or as a last effort adjust the corona hieghts of the primary corona wires. Good Luck...

The copies come out with dark background, how do I service the machine?


There really is not a service mode for this copier. Have you tried to adjust the flush knob on the control panel? The copier is kind of old, when you **** shell it open is there a black small knob on the inside front of the copier.... If so adjust that... Also, I would try to clean the optic's of the copier under the copy board glass. There is a "VR" on the back of the copier to adjust the lamp. Finally, have you replaced the drum unit???? Good Luck

A toner catridge leaked in my Canon PC921. I cleaned it up and installed a new cartridge, but now my copies are dark on one side, light on the other.


Hello,
on analogue copiers, if You have dark copies, that means that You need to clean optics ( mirrors and lenses - maybe some toner get to them ) or check/clean/replace the fixing film!

Regarding poor copy, clean/vacume/change the transfer roller ( beneath the drum unit - on paper path from drawer/bypass, before fixing unit ).

Hope that helps!

it is very possible the dark line on your copies are being caused by the drum. it will all depend on how many copies are on it but without seeing one of the copies the best guess i can make is the drum.

GRAY STRIPES ON COPIES FROM CANON IMAGERUNNER 210S


Have you replaced the drum unit resently? When you had the drum unit out did you see the lines on the drum it self? If so, you need a new drum... If you did not see lines on it the problem may be coming from the fixing film, most of the time if the film is bad you can rub the toner off the page... Good Luck...

Copies are dark


No. It would most likely be the opposite.

The stripes could be caused by contamination of the dev roller, fixing rollers or marks on the drum.

You could also clean the laser ****-glass.

I have a dark line across copies


Whats the make and model of the copier?
One culprit might be the drum.  If you can take a look at the drum from your copier and you see black lines on it.  It could be scratches on the drum or it may need a new cleaning blade to clean the toner off the drum.

Have you cleaned the slit-glass located behind the drum? Its a thin piece of glass that is about the length of a drum assembly. Check that the drum voltages on the drum label have been correctly installed. Perform a AVPC in service mode to set the primary charge value.
