I have the same problem erratically, without a fault code.
I've made the following attempts diagnostic
I changed the corona charging by the crown of another machine
I changed the power supply unit revealing
I changedthe power of load
Ground the drum by hand with temporary wire cun
But the failure continues
You always said black "copies", how about the prints? Do a counter print, how does it look like?
To estimate, if the error is charge related or laser related, tape a part of the dust proof glass with black tape, is the sheet still completly black?
If sometimes you feel a little useless, offended and depressed always remember that you were once the fastest and most victorious sperm of hundreds of millions!
The impression is black, on copy mode or printing mode.
Including printing of the counter.
Thanks for replying
ok, then do the "glass trick" as i described and see, what happens

Thanks for the answer
'll try this
After the test confirmed that the flaw comes from the laser.
Already checked the cables, to no avail.
Now I'm hoping to get a laser and a BCU to continue.

After more than 30 days the machine donīt failed again, the problem was solved by replacing a portion of the wiring harness of the laser.
Apparently, the harness had a false-contact producing Black copies.
Thanks for your cooperation in resolving the problem
