Homebrew PCBs

I've just rescued an abandoned Brother HL-630 laser printer left on 
the pavement near where I live. It was complete and even had the 
printer lead attached.

It had been raining heavily so I took out the drum and toner 
cartridge, dried it out, replaced them and switched it on. It won't 
feed paper properly so it probably needs a replacement drum, there 
isn't much else to go wrong. Some of the toner image gets transferred 
onto the paper before it jams, so the toner transfer must be working.

I might try to get it working properly and see if I can turn it into 
a photoplotter. Has anyone else experimented with this particular 
printer?
