Black on IR C5030

[maximilian500]

Hello everybody,
I have here a Canon IR C5030. This has a very funny problem. He has received a new Drum BK and a new developer unit about 3,000 pages ago. All the prints were still correct from then on. Today I noticed the gray in the middle of the sheet was particularly weak. I then created various test prints via the service menu. It is noticeable that black clouds are formed in the middle of the leaf. Has anyone ever had such a mistake. Perhaps the black toner has become moist? When copied with the lid open, the page is perfectly black.

Maybe someone has an idea for it.
Thanks for replies

Re: Black on IR C5030

The page is PG5 with Dens-K 255. The area is constant and not moving. I mean the light area in the middle. This is only in black. All over colors have no problems. I use the paper this is inserted the machine.
It has rained however today and the machine is at 19 degrees in the room. It may be good that the paper may have become moist?

moisture in paper would effect all colors

sometimes PG 10's do not actually reflect transfer issues ( because of color saturation on them )

faint issue in same area on one color =

-did u use Dust-blocking Glass Cleaning tool stored in the machine.

EXAMPLE OF CLEANING



-check primary transfer roller condition (for Black)
-check single color image on ITB before transfer

Re: Black on IR C5030

I have checked the dust blocking glass and cleaned them. The image on the transfer is good and had no errors. Condition of the primary transfer roller is 43 % (219608 pages). Condition of secondary transfer is 43 % (219628 pages)

On thick paper (250g) black is very goog. No error.

On ITB belt--when stopping---PG5 Black only TP is solid

Re: Black on IR C5030

For both papers it looks the same on the ITB. However, on the heavier paper the expression is perfect. In the case of plain paper, the print is also opaque when copying with an open lid. There's something funny, is not it?

Re: Black on IR C5030

Can it possibly be at the black drum? The drum was only replaced before 3000 pages. Can still have a problem. This may be places that are defective, so that this does not properly recharge. The pattern repeats itself. If it were the transfer roll, would be a continuous strip in the places?

Re: Black on IR C5030

remove drum and swop with magenta and test to cancel out drum.can be dev aswell.so if you really want to test dev you can swop magenta and bk.1 skrew and clip.then it will fit..just put tape over inlet of toner..so bk wont mix with magenta.run 1 page of test again.instead of bk magenta will be there.if prob is still there then you have just cancelled out the dev unit.and if you already swoped magenta and bk drums and 1 page and is still there you have cancelled out drum and dev.then you must start looking at charge.

That won't work on the Adv C5030. The color drums can be swapped around, but the black drum is strictly black. If heavier paper is giving a quality black image, and you're only seeing light areas when print to plain (20lb) paper, I'd try a different BRAND of plain paper.

If PG5 on single colors of M C Y don't display issue, may need to rule out it's a paper issue.?

hi there..yes you can swop drums.yes voltage between the bk and the colours is different but fot test purpose 1 page wont cause any issue.if you take off circlip and remove rod drum will come off.as a technician you shouldnt be a parts replacment specialist. Tests to find where problem is and coming down to the root is how we should all work.if ut was paper then again all colours will be affected.

Re: Black on IR C5030

the drums can not be exchanged. they are not mechanically compatible. I'm just wondering that the result on heavy paper is perfectly fine. Is there a way to re-evaluate the developer? this is also just 3000 pages old.
