Oops again
I was thinking about a copier. Printers only need two
wires, on to charge the drum and one to transfer to the drum.
So, don't look too much for the third wire.
A quick way to check which is failing is to start a print
and shut the power off in the middle, while the paper is
next to the drum. If the charging wire is working, you'll see
the toner on the drum. If so, it is the transfer to paper wire
that is bad.
