Hp HP LaserJet 3

Stripe on Series II

There is a 3/4" dark stripe down the left side of print on my HP LaserJet Series II. It is not VERY dark, but it is noticeable. It is darkest in a 3" long patch that starts about 1" from the top of each page. When I try to clean the paper path the strip is lighter (but still moticeable) for a few pages, then it grows darker again. I am hoping someone can give me some advice about where else to clean. The problem started last night, when I took an old cartridge out and shook it a little to try to wring a few more pages out of it. Now I have a new cartridge in, but the problem persists.

Also, I seem to have lost the little green brush that goes inside the printer. Anyone know where I can get a replacement?

Thanks,
Dale

Only 2 things can cause that, toner cartridge or the upper fuser roller teflon is worn.

Would seeing a print sample help to diagnose which is the problem? I scanned and posted one at http://www.lions.odu.edu/~demiller/printer.jpg. If the problem is worn teflon, then would it tend to become noticeable slowly, rather than all at once? Would knowing that this printer did have some toner spilled inside at one point (got moved with a cartridge inside) suggest a third possible cause?

Thanks,
Dale

With further experimentation, I have noticed that the problem will essentially go away for a few pages if I turn the printer off and let it cool. After a few pages, when it starts to warm up, the stripe comes back. (This explains why cleaning it seemed to temporarily solve the problem, even though I cleaned a different bit each time!)

Looks like a toner cartridge problem to me. If you take out the cartridge after it happens and pull back on the shutter, you'll probably see the black stripes on the photoconductive drum.

Yes, I did. THat makes it definitely a bad cartridge? Shoot, it was brand new too. One made by Xerox.

I looked at the jpg of the defect.
Although it's likely that it's a bad drum,
it's curiuos that the problem started
by removing and re inserting the cartridge.
These printers have a spungy "bumper" in
the cartridge holder area near the back.
It might be loose and blocking the laser's
optical path. make sure the 3 black screws
just above the cartridge are'nt loose.
They hold the shutter assembly which closes
when you remove the cartridge. (a safety thing)

Thanks for the suggestion, but nothing up there looked loose. I actually got the original cartridge out again to see what would happen if I switched back. As I vaguely recalled, the problem was even worse with the old cartridge; the stripe was on both sides of the page. I ordered a new cartridge that will arrive tomorrow; we will see what happens with it.

Thanks again,
Dale

The "Xerox" explains a lot. I just did a side by side demo of a Xerox, a typical remanufactured cartridge and an "Empty" one of our brand (set to the lightest setting to make things even). The Xerox was full and looked dreadful in both text and graphics. The remanufactured one was likewise new out of the box and looked ok in text but dreadful in graphics output. The empty one of ours blew them both away. Still put out solid blacks. Amazing what one can do when one knows how. Word of advice to readers, never buy Xerox or Lexmark cartridges. They are all crap!! Beware of remanufactured cartridges in general, better than 80\% are crap!! While HPs cartridges basically suck!, they are the best choice, even if they cost a bit more. No, we don't sell our brand outside our local area. Opinions expressed are my own, based on vast experience and usually correct.

The new cartridge ($32, made by Solei, if I am reading it correctly) solved the problem completely. I wonder if I can get Xerox to take back the defective one. I bought it long enough go that there is no chance I will still have the sotre receipt. THanks, everyone, for the help.

Dear All,..Please forward this mailing discussion to my mail address, It's very interesting discussion I ever read.

I have had the same probs.I found that cleaning the connectors on the cartridge, and where they make contact with the casing, when closed, usually does the trick.
