Dull lines only on yellow color

[abe223434]

Hello everyone. I have a Xerox Altalink c8030 that is printing faded yellow lines only on the yellow color. I replaced the drum with an original Xerox drum but it did not solve the problem. I swapped the other drums from cyan and magenta to yellow but the problem still persists. I also put two new aftermarket yellow cartridges and also cleaned the lens with microfiber and isopropyl alcohol. The problem is still there. The other colors are not affected. Can anyone give some pointers. Thanks.

Dirt on Led Print Head ( LPH ) or debris on magnetic developer roll from Yellow Developer Unit.

Thanks for the tip. I checked the yellow developer unit and that was the problem. There were three shiny spots on the metallic drum where the iron filings would not stick. I cleaned the magnetic rod. It fixed two of the lines, but the third one was not fixed. I'll order a new developer unit. Thank you and please keep up the good work.
