    It can also be the fuser Assembly. Is it the same spots every time? does it get better or worse when the printers stays on for couple hours?

    Hmm could it be the heater then? I should guess on that, don't now what else it could be

Check for any small paper jam. Check the rollers, also use an alcohol swab to clean the rollers and check for ink leaking. Check you ink pad, it could be time for a new one.

I'm trying to print wedding invitations on my Canon MP460. I'm using a cardstock thickness of paper and have set the ink levels for "Other Photo Paper" on my Mac. The paper has been going through...


Sounds like the ink isn't having time to dry and is rubbing along paper.

Paper may be too thick. If it prints OK on normal paper (test first) but not on thick card, then it doesn't support thick paper settings.

Printer: HP Laserjet 1010 model Black dots appear on the paper


Dots, Lines and smudges on the printouts are due to deteriorating cartridges and cleaning the green drum of the cartridge may help temporarily. Take out the cartridge and gently clean the roller/ green drum with a dry, soft, lint-free cloth wiping off the toner dots marks/ lines.
Also, make sure that the visible inside of the printer is clean and ther is no spilled toner inside, which sometimes results in dots.
Let me know if any further clarification/ assistance is required.


GoodLuck!
Dont forget to appreciate the solution if I could have been of any help!

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.

Doubt it be the fuser(100 000life), "just magenta dots".... fuser would be "all smudged" or "black marks" , "the print rubs off" , "paper is creasing or jamming"

Can prove it by stopping a print (open door) when paper is1/2 way threw machine, you need to stop it before it goes threw the hot bit, so you can tell if the hot bit (fuser) puts the marks on the paper.

Transfer roller one would expect to effect whole print Smudged/Faint,uneven density

It will be the imaging unit ( 30 000 pagelife Ouch$ ) or possible leaking toner (if aftermarket)

Remove imaging unit and inspect film you should find image of lines, dots are usually chips or sticky stuff on drum surface, carefull no oily human fingers on surface please.

When stopping machine mid print and perfecting your timing, pull out the imaging unit and look at replica of your print notice if marked and where.

Hope this helps
