Smudges down left side of paper

Hi, We have a laserjet that has begun to start putting spaced out "smudges" on the left side of all print outs. While they are not extremely dark, they do not look professional and we need this fixed. On a paper path test, the smudge appears a little before halfway down the page, right above that is one that is similar but indented and then about equal distance from the bottom is the same smudge and then again at the very bottom. What do I need to test to figure this out? We are starting to get multiple complaints and have to find a fix. Thank You, mtaffer

Re: smudges down left side of paper

Maybe something attached (corrector fluid or adhesive)on drum (green cylinder - don't touch it!) or more probably the fixing film on the fusing unit is damaged (probably some paper clip left over input bin, or trying to remove a paper jam with some sharp-pointed thing) If you have some other printer like this around, try with another print cartridge, if error persist , the fuser film is damaged...

HP LaserJet 4Plus - just changed the fuser and rollers - was getting smudges and shadow on the printer paper. Now getting (on the left 1/4th of the page) light areas with little or no print. The shadow...

Take the toner cartridge out of the printer. Shake it side to side. Reinstall it and print something.
See if that fixes the output.
Could also be the transfer roller.

I have a grey/black line all the way down the right hand side of the page

Run a half test.
Put paper in the manual feed tray.
Print something, anything
When the paper is 1/2 way into the printer, open the cover.
Pull out the toner cartridge. Look down at the paper.
Does it have a black line on the right side?
If yes, replace the cartridge. If no, replace the fuser.

My HP 4100 printer prints with a black smudge clear down the page. I clean the roller but continues to print bad copies. Should I replace the cartridge?

Problem is either the cartridge or the fuser.
Put paper in the manual feed tray(tray 1)
Print something. When the paper gets 1/2 way into the printer, open the
top cover. Pull out the toner, look down at the paper.
If it has the smudge replace the toner. If no smudge, replace the fuser.

HP4-smudged copies of printed text are appearing lower on the page...Any ideas on the fix

Run a 1/2 test.
Put paper in the manual feed tray(tray 1).
print something. And watch the paper. As the paper gets
about 1/2 way into the printer, open the top cover, remove the toner.
Look down at the paper. If you don't see smudged text, the fuser is probably bad.
If you see the smudging, replace the toner.

HP Laserjet 1012 - Little smudges on page.

You probably have an excesive amount of toner building up on your rollers or fuser. A cleaning done by a certified technician should take care of this problem for you.

Ink smudges on the right side of the paper


Your problem is due to a worn fuser unit (upper fuser roller).

The teflon coating has worn again, alowing the toner to stick to the roller and then "repeat" about 3x down the paper (getting fainter each time).

You need to order a new fuser unit.

Make sure you order the currect voltage (US or UK)

This problem is with the fuser. It needs to be replaced. They tend to burn out right in the center leaving a rolling smudge across the page as the unfused toner left on the roller gets printed on the next roll-over.
