    Thanks so much. I am not sure what a fuser is though.

    Thank you for taking the time to explain this to me. I am most appreciative for your advice and support. You get a 10 in my book.

    Since you are such a guru, do you give advice about printer purchases? I am a mobile notary and ideally, would like a printer with 2 inputs for regular and legal size paper. I don't want to break the bank and I was thinking about another multipurpose printer such as an HP 2727mfp. Do you have any other ideas?

Two parts of the printer can affect this.
1) the toner cartridge
2) the fuser

Testing can be done to determine the problematic part.

Do a print using manual feed. Once the last bit of paper goes into the machine, open the printer door.
Remove the toner to check if smudge is there.
Replace toner cartridge if there is smudge, replace fuser it not.

    You can check out what is a fuser from below link

    "The paper passes through rollers in the fuser assembly where heat and
    pressure (up to 200 Celsius) bond the plastic powder to the paper.
    One roller is usually a hollow tube (heat roller) and the other is a
    rubber backing roller (pressure roller). A radiant heat lamp is
    suspended in the center of the hollow tube, and its infrared energy
    uniformly heats the roller from the inside. For proper bonding of the
    toner, the fuser roller must be uniformly hot.

    The fuser accounts for up to 90% of a printer's power usage. The
    heat from the fuser assembly can damage other parts of the printer, so
    it is often ventilated by fans to move the heat away from the interior.
    The primary power saving feature of most copiers and laser printers is
    to turn off the fuser and let it cool. Resuming normal operation
    requires waiting for the fuser to return to operating temperature
    before printing can begin."

    Unless you are an authorized service provider you
    will not be able to get the fuser yourself as it is not a customer
    replaceable part.

    Give the troubleshoot steps a try, 9 out of 10 the issue is with the toner cartridge.

    Please give me a rating if it works for you. Thanks

    sorry I am not familiar with each brand of printer. So I could not really give you any good recommendations. I just fix MFP at my work place.

HP LaserJet 3330 will not print multiple copies

Does this happen only with some documents/software? I have a different HP printer (a LaserJet) that does the same thing only with PDFs printed from another program. (This happens with PaperPort and browsers using the Adobe Reader plug-in, for example.) If I open Adobe Reader and then open the document in question, I can print multiple copies correctly.

I hope this helps.

I have a HP Color laser jet 2600n printer. I have tried different Glossy paper, marked for laser jet, but still get bad smudges on my prints. these smudges are still visible on the next ordinary prints...

You need to ensure that you are telling the printer that and your print driver that you are using glossy paper as this will change the speed that the printer prints at and ensure better bonding.

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.

Xerox Phaser 8560 mfp Printing issue

That really sounds like you need to replace the maintenance kit.
The white roller most likely is black and has depleted itself of lubricant a bit prematurely.
