Hello, Your problem have only one solution - open laser/scaner Assemblycarefully and clean all mirrors inside whit dry cloth. Dirty mirrors is the most frequently problem for 1600/2600 series If you dont know how to do that just visit HP service Good luck!
Your laser/scanner assy needs cleaning. The main fan, located at the bottom is getting dust from below the printer and blows it to the lower (magenta) mirrors of the laser/scanner assy. To repair, take the printer apart. Remove side and back covers. Then remove the metal frame with the boards. The laser/scanner is a black box behind the frame. Take it out and open it. Clean the mirrors. To make the repair permanent, cover the fan's vents with sticky tape. I usually remove the plastic gratings to seal better. It will cause no problems to the printer.

Oct 06, 2009 - NO, never use cotton ear buds, sometimes they landed some fibers to the mirrors and you will get bad image :)
This is a common fault on this model. The solution is to strip out the laser scanner unit. The laser scanner can be reached by removinh the back metal cover of the printer and the controll boards behind it. You need to clean the mirrors inside the laser scanner, for this you can use surgical spirits and cotton ear buds.Hope this helps. Any other queries, you can mail me firstname.lastname@example.org
This is a common problem with ALL of the variants of this printer that have had either a lot of pages printed, or particularly had a few leaky cartridges in them.
The problem here is not with the toner cartridge, (you'll get this with ANY cartridge you use), and your magenta cartridge will work fine in another printer (which was working properly.
The problem is dirty lenses/mirrors in the laser unit. It's quite an involve job to get to the laser unit, and even when you do get it out, you need to be extra careful when you dismantle it to clean it, otherwise you'll either scratch a surface silvered mirror, or disturb the alignment of some component.
Safest bet, if you are not sure of your mechanical abilities, is to replace the whole laser unit, or go for an exchange reconditioned printer.
Cause is dirty lenses and or mirrors in the laser unit.
This happens over time (as the laser unit is not sealed), and particularly if you've had a leaky toner cartridge. Unfortunatly there are a lot of poorly remaufactured, leaky cartridges around for these printers.
Solution is remove laser unit, open it, clean lenses and mirrors (very carefully to avoid disturbing alignments, and scratching).
The laser unit is deep in the printer, so it's quite a lot of work, but very rewarding when you've fixed it.
Alternatives - buy a replacement laser unit and swap and clean old one at leisure, or get an exchange refurb printer - if you think your mechanical skills aren't up to it.
This is caused by dust in the scanner assembly. There's a fan right by the magenta laser scanner that blows dust and particulate matter in the air directly on that laser scanner. Requiring its removal and careful cleaning of all lenses and mirrors. Unfortunately, this is not covered in the service manual. Getting the laser/scanner out is not too bad: Start by removing the printer covers, the rear plate, and the plate on which the DC controller and formatter mount. Remove the four laser/scanner unit corner screws and the single screw for its cover. Be careful to remove the small shutter spring on the cover before removing the cover. Use a strong flashlight to carefully examine the copper-colored mirrors for dust. Use dry cotton swabs to carefully clean all dust from the mirrors and the lenses. Blow dirt and dust from the inside of the scanner box. You will notice that the bottom mirror, facing up, is the one with the most dust.
