I'm wanting to get a colour laser printer working for a community health association that is inexpensive per print, so I picked out an hp 2600n. They are likely to be printing about only 300 pp/month from a single linux laptop in our library room.
The first 2600 is unable to produce a M image from either M cartridge, and both machines are very smeary. Been through service cleaning routines and full block cmyk pages on both machines several times.
The advice I've picked up on this forum so far is as follows so unless anyone suggests otherwise I'll start with a thorough vacuum clean down and disassembling both machines to clean up all the mirrors & lenses. But, for example I'm also wondering if there are drum wiper blades inside the cartridges that can be accessed and repaired to stop streaks, or if it's really all down to dusty laser paths?

2015 - I worked on these a good bit back in the day.
I'd recommend looking at the cartridges first. It looks like bad cartridges. I see the magenta is OEM, but, doesn't mean it's good. The biggest issue that I usually ran across is a dirty laser/scanner. This is a known issue with these things. Remove the laser/scanner, open it up and clean the lenses.

You can only tell after a cleanup. Remove the fuser unit and look at the rollers, if they are good then, you can spend money on the consumables and have a decent printer. Don't be alarmed at the printout you see before cleaning and repair.
After cleanup, stop the print before it reaches the fuser[ open the door] and then look at the toner cartridges drums and see which one are bad, probably all are. Check the levels of the consumables from the machine or connect it to the webserver and you can see it there. Then price out what need to be changed and you have to decide what you willing to spend.

Exactly, first step should be the lens as it is in idiotic location. I had the same printer also given for free.
Less than 200 pages printed on genuine consumables - same effect as on picture above. Cleaning the cartridge did nothing. Seems like developer blade got weaker with time and started to dust the toner on the page.

Fading Red Tones on Color LaserJet 2600. HP Color LaserJets 2600n, 1600, and 2605 share the same basic Canon engine design. One aspect of the design brings the common problem of scanner optic degeneration due to dust buildup on mirrors and lenses. Since the most vulnerable mirror reflects its laser beam to the magenta toner cartridge, red tones are the first to show fading.
