HP Color LJ 8550 prints black pages

[erollbilibani]

I have 2 Color Laser Jet Printers, 8500 and 8550. Both use same consumables and same Kits. 8500 prints without any problem, 1000 pages if needed without a brake. However with 8550 I have a huge problem. It prints 20 pages OK and then after 20 pages it starts printing stripes in cyan magenta or yellow and sometimes prints only black pages. In some forums I was advised to change the kits and consumables, which I did, but the end result is the same. Has anyone experienced the same problem? If so, is there a solution for this?
Once more, this happens only with 8550 model, not with 8500.
Thanks in advance.

Weird. Bad printer memory?

whereabouts is this stripe you are describing? I had a problem where every so many pages a 8500 would print a multicolored stripe across a page (and also had a little ghosting). Ended up being a broken ICL arm. The replacement of the arm and spring fixed it. Would be an idea if you check that out (if you open the right side of the printer and remove the transfer drum you should see the spring located to the right of the cleaning roller).

Greg, It isn't printer’s memory, because i did a weird combination just to test the memory. as said in my previous post I have 2 printers, so i swapped the memory between printers, but the result was the same.
Michael, i checked the ICL arm, it looks ok. at least it's not broken.
sometimes i'm afraid that i was the lucky one to get a printer with factory error.
Anyway thanks to both of you for your effort to assist.

Hello erollbilibani,

Did you ever have a solution for this problem?
We have exact the same problem with one HP CLJ 8550?
