Re: mp 8000 image defect

I agree, had this a few times with faulty memory modules. Give it/them a clean and reseat, if still occuring then a replacement is needed.

Re: mp 8000 image defect

no noises. copying works fine. i actually thought it was the document. i was appearing always on the last 3 pages of a document. (same pattern). Sometimes is black thick lines, sometimes its 1" band with horizontal lines. its always towards the end of the document. i will try the memory modules.

Copying works fine? Well, that makes my previous post totally wrong, sorry about that.
On the other hand, the machine prints OK except for the last three pages of a print job? If that is the case, it is quite unlikely the machine is the problem. The machine is just printing the data sent to it by your computer after all (if there was an issue with the machine, everything you printed would look the same), and as such it is far more likely to be an issue with the application you are printing from.

Does it happen with all connected PC's? Is it only 1 specific document, or everything? Have you tried another driver? Firmware?

I agree with sandmanmac!!! test other pc's or better yet put that file on a laptop and print via crossover to see of you can recreate it...............

I've had a few weird CQ issues that have been sorted with a new BICU. I'd give that a go first.

its actually different documents from different pcs (there are a total of 6 in the office). they only thing they have in common is the application they use (creates pdf's) and the mp 8000.
i uploaded a pdf from my google drive and tried printing it. It had the defect. I uninstalled acrobat from 3 pcs and installed the latest acrobat reader. Still no luck. I installed a pcl 6, pcl 5e and ps driver with no luck.
