Hp HP Color LaserJet 2840

Copying with HP 2840 in black//white bad, color ok

We have a HP 2840 (just installed latest firmware, no help) and if you copy in black and white, the print is messed up, streaky and only good in the middle. If you use color, all is fine.

If you print normally, all is fine.

I don't know where to go on it.

No error codes.
