laser printer - streak across paper

[shiunn]

I have a 4-5 year old HP Color LaserJet 2600N that has been serving me well. Recently, it suddenly began producing prints with 2 vertical blue streaks, along the plane of the paper - one on left, one on right side of the paper.

I tried to print a blank page of document, and it still produces the same blue streaks. What does this mean? Is my fuser at fault?

Any advice is greatly appreciated. Thanks!

sounds like the heads are dirty. It just needs a good cleaning.

The brush / scraper thingie that cleans the photoconductor drum is not adequately cleaning that portion. Like a windshield wiper blade with a little dimple taken out of it leaves a fine line of rain across its sweep pattern. Some (Lexmark) laser printers demand a photoconductor replacement every 2-3 toner cartridges. You'll have to check with HP to see what to do with your particular printer.

I think i found the culprit. it's the cyan cartridge.

When I removed the cyan cartridge, the "bottom oval" is clean. How do i clean the "top oval". And by the way, can someone teach me the technical terms of "bottom" and "top" oval?
