Color Print Quality


In my experience, the fuser has always been the cause of the lines.

Black line on the page when printing fax or making copies


The lines may come from the toner/ drum cartridge. Try stopping the job by opening a cover, and see if the defect exists before it reaches the fuser.
The fuser for the F110 is PN 126N00235
The toner/ drum unit is 013R00605 (several alternate numbers exist)
And it could also be the transfer roller 022N02107

Hope that helps

The black print jobs have a shadow about 3 inches down the page


I had replaced the fuser - no improvement. I removed the fuser, imaging unit & transfer roller. CAREFULLY using a vacuum cleaner I cleaned all units and the internals of the printer, rotating the roller on the imaging unit to clean all parts. (Warning Place Imaging unit on paper as toner escapes) After a few test prints the page cleared and duplicate ghosting cleared.

My Ricoh Aficio CL2000N is printing several faint lines


Couple possibilities:
Fuser hot belt has wear lines transfering to the page
Black pcu needs to be replaced
Transfer unit is not being cleaned properly and needs to be replaced.
Remove each of these assy and inspect them for wear or lines that corespond to the lines on your prints.

Replaced the 4700 image transfer kit and am still getting lines through printed documents


Hi jclaeys

Does the transfer kit include the fuser on this model? If not then it's highly likely that that's the part that needs swapping. I have also seen faulty toner cartridges produce lines so it's worth check that too.

Hope this helps!

Black vertical lines on laserjet 4650 print out


99% of the time, this is the imaging drum or fuser.

Pull the imaging unit (same as imaging drum - they are interchangable) and examine the greenish glass tube. Does it have black streaks along the same lines that are on the paper? If so, then it needs cleaning / replacing. Don't touch the glass!! Use Q-tips and rubbing alcohol to gently clean the lines off. Air dry and replace into the machine.

If the imaging unit doesn't have lines, then it's the fuser. This can be replaced as part of a maintenance kit. If you've been using the printer regularly for more than 9-12 months, It's probably time for a Maintenance Kit for the machine anyway, which includes a fuser. I recommend Parts Now (http://www.partsnow.com/) for replacement kits, which have instructions on how to install with them.

Ricoh Aficio CL3500N is now printing all documents with lines/streaks all down the left margin of the page. What do I clean or replace to get rid of these unsightly lines printing on every page?


you can try printing a page in black only, then one page each in the 3 other SINGLE colors: Cyan, Magenta, and Yellow. this will eliminate/ confirm one of these causing problem.

the replacement of Transfer Belt Cleaner or Cleaner Assembly is another to try after the above separate-color thing. see if there's a status page of life remaining on replaceable items, including the Transfer belt assy.

i'll assume you didn't scan the job- - this isn't a multifunction scanner/printer type machine?

ok, next in line is to check the Fuser unit, the part on the upper left side/top of printer. if the same streaks appear on the Main fuser rollers, these fuser units cost about 350 bucks. there is also a Fuser Kit, which costs much less, but its job is to add Fuser Oil to the fuser unit and keep paper and ink from sticking.
a guy could suffer sticker shock from the costs of running one of these, considering you could drop a grand buying all 4 drum units, a fuser unit, and a transfer belt assy. . . .

Hp 2420 vrtical line in page


Hello,

This issue can be due to fuser. I am sure you have changed the toner cartridge.
To confirm its a fuser issue, please perform the following:
1. Try printing a configuration page from tray 1, pull the top cover, as soon as the media is 60-70% inside the printer.
This would stop the paper before reaching the fusing assy.
2. Remove the paper and check if the line exist.
If exists, fuser is not faulty.
If it does not, then transfer roller, laser/scanner assy is faulty

- If fuser is faulty, perform the cleaning page as following
1. go to configure device > print quality > create/process cleaning page
perform cleaning page 5-6 times, however, if the line is due to fuser, then fuser needs to be changed.

Let me know the next update.

Lines along edge of paper


1 of 3 things I can think of off top of my head.
Since they are straight, I would suspect the transfer unit.
If it were just one color it would be that imaging unit.
Unlikely the fuser.
It doesn't sound line an issue called bar coding ,where the machine prints random lines. That would be a software issue.
Take the transfer unit out and inspect it for the marks.
I am assuming the streaks are on all colors correct?
If it isn't on the transfer belt, and on all colors check the fuser and see if its latched.
