HP LASERJET 4250n

When I print, there is a smudge. Due to spacing, looks like it's on roller. How do I check this.

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.

If you print 2 pages and the spacing are equally spaced. then you are right. it is on the roller.
you have to take the ink cartridge out and use water or acohol on a coffee filter to clean them.

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.

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.

Ink smudges on the right side of the paper


Hi,

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)

Reseat the paper in the paper tray, and replace the pickup rollers for both trays, note the pickup rollers are in the trays and under each tray.

HP Laserjet smudges across entire page


More than likely you have a bad toner cartridge.

Poor quality smudge and ink blotting marks in the centre of any printed document


Try performing a test by printing a test page from Tray 1 and open the top cover as soon as the paper is 60% inside. The paper would jam below the toner cartridge before it reaches the fuser. Remove the toner cartridge carefully and verify if the smudges occur. This would eliminate the fuser. If the print quality is fine, then you need to swap the fuser.

Smudged printing


Sounds like you are either having a cartridge or fusing assembly issue. Here's how to isolate it. Look at the "tire tracking" and find where the mark repeats itself. Measure the distance between the 1st occurance and the repeat and use the guide below to identify the source.

38mm or 1.5" = cartridge
55mm or 2.17"= cartridge
62mm or 2.44" = Lower Fuser Roller
74mm or 2.91" = Upper Fuser Roller Film
93mm or 3.66"=cartridge

If the spacing is cartridge, simply replace the cartridge. If it is fuser you will need a replacement fuser. Replacement rebuilt fusers are available for about $65.00 plus shipping on exchange from Dale at Seattle Platen, 1-800-221-2388.
