hi all. i have the above m/c here that the customer was complaining about CQ issues. removed and cleaned the dust out of the laser which has made everything more vibrant but now i have no magenta on the demo pages. engine test is fine with all colors. has only happened since i stripped it apart. have gone over it twice to double check everything and still no go. any ideas???

[slybot]

forget about this. it decided to fix itself. thank god for that!

No matter which color laserjet it is, HP seems to always have trouble with the Magenta cartridges. Weird.

By design, magenta is at the bottom of the pile of cartridges which forces mirrors in the laser to look up and collect all the dust possible floating around the inside of the machine. The surprise comes during disassembling of the laser unit, there are no dust seals under the lid to protect the precious scanner.

Couldn't think of anything on your own to say? Or did you just post to show your link?

[Hank]

ugh.What link?

[JustManuals]

Not you.

Someone after manuals, but before Hank copied manuals comment. I gave him a bad rep, but it seems he or someone removed the post. That's good.

pieces of snot these things are. think that will be the last one i will work on. will refuse to touch them next time (if i can get away with it)

thanks for taking an interest though everybody

Faded print, especially magenta, is 90% dirty optics, but you have to remove the scanner and hold it up to the light to clean it really good. No parts required but it does take time. If you get in a hurry you may forget to connect something good or forget to use ESD procedures and then you have a bigger problem. I've only had to replace the power supply and the fuser other than clean the optics. The printer is not worth any other repair.
