Have you tried changing the magenta and black toner cartriages?

SOURCE: right side of every page has pink strip down page

Either your magenta cartridge is leaking out of the right corner or you have a defective magenta drum.
(maybe it got scratched when changing the cartridge?) If it's the magenta drum, you have to replace all the drums since they come in one unit. OEM part only.

First of all you may have 1 or 2 things going on here. First of all the HP2600 series is prone to having the laser optics get toner dust on them which causes light prints usually on on side or the other. If your light print on one side is on black and all the colors then it may be the fusing unit. Another indicator of the fuser being the cause is the double imaging.....meaning something that is printed at the top of the page gets re-printed farther down the page. Does any of the print, especially on the double image/light side rub off? If so then it is definately the fuser. In case you don't know the fusing unit is the part that heats up and "fuses" the toner onto the paper. It is located right where the paper exits the machine. You can try a test for a fuser problem by printing something then shutting the printer off before the paper starts to exit the printer. Open up the printer and look at the sheet being printed. Is it light on the one side before it goes thru the fuser? If so then you need to clean the laser optics. If it is not lighter then this will prove the fuser is the cause. You can find the fuser units all over the net and they are easy to swap out. As far as the laser optics go you can try the basic cleaning yourself by removing the 4 toner cartridges. Behind these units you will see kind of a large black box with 4 evenly spaced "slots" running from side to side. Inside these slots is a plastic lens that the laser beam goes thru on it's way to the toner cartridges. Just take a cue tip/cotton swab and clean these 4 slots. Once clean just re-install the toners and test to see if the print quality issue is improved. Sometimes the whole laser box assembly must be removed, dis-assembled and cleaned. I recommend you hire someone to do this as it can get a bit much if you do not have experience with these machines.
Good Luck and Thank You for using Fixya.
