    I just put new ink cartridges in. There are many ink smears now. I've cleaned rollers, ink nozzles, and the projections inside. Any other ideas?

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.

HP Lexmark 4050N Printer is smearing pages with faint ink mark.


This is more then likely due to an old or bad toner cartridge. Away for you to find out is to run a test print and if you listen close you can hear the paper advancing through the printer. It might take you a couple times but try to catch the paper at a point in the printing to where it would be just passing by the toner cartridge and ope the top cover. Remove your toner cartridge and pull the paper out. But becareful when pulling the paper out to not rip it or get toner on you. The toner has not yet been bonded to the paper yet until it passes the fuser at the back of the printer. If the paper shows the smear just after the toner cartridge then there is the issue.


Best of luck... And have a Happy and safe Holidays..

Poor prints and paper jams


Sounds like you probably need a new fuser. Smearing is a good indicator of the fuser not getting the toner to fuse to the paper, also, if it is jamming a lot near where the paper enters the fuser, there is a good chance there is some damage on the fuser unit itself.

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

Ink smears on the paper


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

When printing on my HP 4200 printer, the pages are coming out hot


Simple answer:  It's Ok if the paper is coming out hot out of the printer. The paper passes the fusing assembly just before it leaves the printer and that is normal.  I would be worried it you smelled something burning or saw scorch marks on the page but that would be unlikely since there are temperature controls built into the printer.. There is a way to adjust the temperature of the fusing assembly from the printers control panel depending on the type or thickness of the paper but it'd leave it alone if your only problem is feeling that the paper come out hot.Your user manual would describe the procedure if you wanted to change it..  Also check your printer configuration settings. If you sent a print job on regular 20lb paper and its stated as thick paper type  in the printer settings, the printer might adjust the fuser hotter or slow the printer down some to compensate. Hope this helps

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.

Help with Brother MFC-8500 all in one printer


When you get the paper, can you smear the print with your fingers, or is printed on there properly.

if you can smear it, it would be your fuser not doing its job properly, if you cant, then its your replacement toner as it most likely incorporates the drum in it, which i think is your problem.

Xerox Phaser 8560 mfp Printing issue


That really sounds like you need to replace the maintenance kit.
The white roller most likely is black and has depleted itself of lubricant a bit prematurely.
