It could be the paper is not absorbing the ink properly. Try changing the paper/quality setting in printer properties.

Bad streaking on print xerox 8550 phaser tried the troubleshooting feature/eliminate light stripes with no luck


The best way to tell if your problem is clogged jets, or bad maintenance kit, or something blocking jets. Is to look at light stripes test, and see if missing jets are all in a straight row or all over the place. If the missing jets number less that 10 you can use jet substitution to avoid the streaks. If you are using Media Sciences or some other after market ink, check that most of your problems are not in the cyan area. Media Sciences produced a bad batch of cyan which clogged the jets pretty bad. The good news is that if their ink caused the problem they will pay for some one to come out and replace your printhead. If you LST (Light stripes test) has a smear the entire vertical lenght of the page. You have either a bad maintenance kit, or a piece of paper, lable etc..rubbing against the drum while printing

you may have to clean the print head. since the jam cause the smear, and there still have some ink left on the print head.

When printing the printer is leaving smears on the left side of the page and random letters. If I make 20 copies, the first 5 and the last few will have the marks. I already changed the drum and all...


you need check
1) you may make sure the smear occur after the photo drum unit or after fuser unit, you can stop printing when the paper goes around between the drum unit and fuser unit,
2) clean or change fuser leaner if the random smear occur after the fuser unit(not after the drum unit).
3) still check new drum unit there is a cleaner on it, it could be the smear occured if not enough cleaned drum surface
hope you fix it

Phaser 8200 Smears on Linen Paper


Your maintenance kit is running low on oil and needs to be replaced. Since the image drum is not getting enough lubrication, some of the ink from the previous page is sticking to the drum and carried over onto the next page. Also, try to match the printer paper type to the paper you are using. It will adjust speed, temperature, etc. to optimize print.

Printer leaving smear marks on paper


Are you using genuine Canon ink carts?? The cheaper "pattern" carts often use lower grade inks that don't dry as quick.

Also try feeding two or three blank sheets through the printer to clean the rollers and guides.

Prints roller smear marks


Laser printers do not use Ink. The problem is most likely a defect on the drum, which in this model printer, is part of the toner cartridge. Replace the black toner cartridge with a known good one and test.

Xerox 8400dp, on righ hand (facing fron of the printer), paper is glued to drum to this extend as to tear pieces off. seem like either oil is not greasing the drum or drum is not heating? or overheating?...


I would start by taking the maintenance kit our and looking at the white roller. See if it is deplted of oil, or see if it's damaged.
If dry or damaged, replace it. But once you do, run the procedure for cleaning smears from copies.
You may have a transfix roller problem also.
That is the back roller that presses the paper against the drum to pick up the ink. It is below that green guide under the upper cover that picks paper off the drum.
I really suspect a problem with the maintenance kit.
Let me know if you notice damage to the kit or the roller. IF they are fine let me know . You could have a bad drum wiper blade.

Lines


I will give you all the reasons I can think of.
1, If the line is only there when running through a document feeder and not there off the glass. The small strip of glass directly under the document feeder is dirty.
2. The drum has a scratch on it, or the cleaning blade is not cleaning the drum properly. Would require that cartridge replacement.
3. The fuser roller may be work in the middle. You would notice some reprinting , or ghost copying if that were bad.
4. Less likely would be some piece of fuzz in the light path, or a small piece of paper or tape in the paper path smearing the ink across the page.
If your machine prints, see if the line is on a print, if its on a print and not on the copy then it is scanner related.
