Magenta fades or prints light on HP Color LaserJet 2605dn printer
Hi there, the toner model is HP124A, when it prints, seems magenta fades on the paper, i've tried shake it and print, no improvement. Any advice?
One commonly reported issue on the HP Color LaserJet 2605dn series printers is a "light print" or "fading" of the Magenta (red) color. Usually this problem is caused by a dirty mirror inside the printer's laser scanner, and the problem is specific to the Magenta color. (Unfortunately this printer's laser scanner is not sealed very well so particles can leak in, and the Magenta mirrors are the lowest mirrors in the machine, so it tends to catch particles falling from above.)
The fix is to clean the mirror; however, accessing the laser scanner is a big job. Many times people prefer to call a technician to do this cleaning. On average a technician will take 1 to 1.5 hours to access/clean this mirror; if you are going to try cleaning it yourself, and it's your first time disassembling the printer I would plan on several hours.
Essentially to get to the laser scanner, you need to remove the outer panels, remove the rear cover, unplug the DC controller board, reroute the wires and remove several wire guides from the right side side and top rear, unscrew & remove a metal plate which holds the DC controller & formatter, and then unscrew & remove the laser scanner assembly. With the laser scanner in hand, you can remove the cover and wipe down the mirrors with something soft & non-abrasive (usually we use a cotton swab).
