If you blow up your scan all the way 6400% I think you'll see something like whats in my picture. Essentially there is some sort of lint dragging through the developed image on the drum, or dragging through the transferred, but unfused image on the paper. Lint this small is nearly invisible. Certain Sharp models were prone to this effect. Use a stretch-N-dust to wipe down every surface close to the drum, or near the fuser inlet. =^..^=

Does it smear on plain paper?

Re: hp lj600 m603 smear

I kind of doubt that it's lint. The smears are across the board, and I've never seen the lint problem in HP's. I would guess more the paper... at least, that would be my first guess with my limited information. Try running it through tray 1... usually, tray 1 will run at a slower speed. If it changes when you run at a slower speed, it's more likely the fuser. But if it only does it to this letterhead, and not to plain paper, then there's your answer.

Re: hp lj600 m603 smear

Did you perform a half page test to rule out the cartridge?
Did you update firmware for the printer?
Does it happen only on that paper or does it occur with other types?

Re: hp lj600 m603 smear

sorry been busy it appears to be doing it on plain paper as well, the original problem was only the rough paper the inside of printer is spotless clean, did not update firmware I am going to try and get back customer to try a different cartridge

Re: hp lj600 m603 smear

firmware has now been updated Blackcat your sample show white line in black area then black line that follows mine is a black line that follows off the black.
wiped inside it is now a new cartridge new fixing film and lower rollers and bushings only thing I don't have is a transfer roller ?? now I have reread the help ran paper through tray one (manual feed) and it seems better so will try at customer site with customers paper

Re: hp lj600 m603 smear

If it's better with tray 1, then it's probably a fuser problem. Replace the entire fuser unit... although, I've been assuming you've tried one or two different ctgs.

Re: hp lj600 m603 smear

Did you tried the print half test to rule out the toner cartridge as stated by "prntrfxr"? You mention you put in a new fuser and replace the fixing film, lower roller and bushings. My guess is you never install a new fuser? Seems like the fuser is the cause of the problem>

I'd bet my right arm it was the fuser.

Re: hp lj600 m603 smear

Huh, I have seen the fuser entrance guide get enough of a charge that it could cause toner scattering like this, but I haven't seen that for some time. Could that be the problem?

Is there any grease/fingerprints on the sleeve?
