Too light prints.

I cand find result with this problem - too light prints.

I did this procedures:

cleaning laser+mirrors
inspected all high voltage contacts
new toner
drum reached only 50 percent
cleaned corona wire, grid, repaired all contacts

please any ideas?

did you tried with new drum?
maybe someone reset drum counter earlier.

Wow, you've put a lot of energy in this little, cheap device^^

Are the drum and toner OEM?

You can try to reset the toner bias - you'll need fiddle something at the toner cartiridge backwards so it does hit a switch inside the printer. You should also check if there is a possibilty to enable a toner save mode within the printer driver.

Have you checked if this machine has the toner save mode activated?
Happened to me once, all I needed to do was to clear that mode out.

great minds think alike^^

One last thought.

I had a series of OEM cartridges (new-in the box) that were missing the small white buttons & springs that press the toner cartridge up to the drum. Cartridge #1 was missing the left button & spring. Cartridge #2 was missing the right button & spring.

This one was a strange one to diagnose. New cartridge #1 is light at the left. Change cartridge to #2, now light at the right.
