    faded page with new toner -- LJ2420

    Laserjet 2420

    I was having print quality issues with a grey background and faint type.
    So I bought a toner cartridge.
    This is an original HP Q6511X. However, while still sealed, was several...

    Re: toner leak in "new" cart

    Well, yes, but I often do it towards the end of life to get a few more pages out. Never had any spray of toner.
    Maybe when it's full it's a bad idea.


    There was a little bit of sponge that came...

    toner leak in "new" cart

    Bought a genuine HP Q6511X on eBay. Box was opened but the cart bag was sealed. Supposedly a "purchased in error" return.

    Opening the bag, no loose toner and the cart looks clean. -- see photo....
  5. Re: LaserJet 2420 grey background

    Interesting, thanks for heads up.
    Until recently I lived in Hong Kong, and ebay is uneconomic there, ridiculous shipping fees for almost all items.
    More local vendors in Aust.
  6. Re: LaserJet 2420 grey background

    Still can't see a shield on the slot, or several mm inside it. No mention in the service manual.
    But hopefully the problem is just the cartridge.
  7. Re: LaserJet 2420 grey background

    There's a slot above the cart, as image. No shutter or visible glass though. The laser unit is inside so presumably has the shield as part of it.
    Won't go into there unless the new cart doesn't fix...
  8. Re: LaserJet 2420 grey background

    Yeah, that seems likely. I asked in the manuals forum for some docs on the cartridge and got a remanufacturer's manual.
    That included a list of common problems:



    Which describes the printout...

  11. Re: LaserJet 2420 grey background - posted on behalf of AlanHK

    It's not a HP cart, but not a refill. I'd done a thousand pages in the old printer with it over 18 months and quality was perfect.
    Done another 500 or so since then hoping it would come good, but...

    Re: First post - delay time

    Same with me.

    It seems "junior" members' threads in the tech forums must be approved. And no one is doing that now.

    I'm using XP with a LJ 2420. And I sometimes run a DOS program from 1987 that can print to it.
    Most, perhaps all, laserjets run PCL and usually PostScript, even if they also have a newer print...

    Would have been nice if that was in the manual.
