Sorry, I wrote this in a hurry and did not jot down all the specifics. So

first set printer off-line then hold select key for 3 sec.s
if that doesn't work try holding select key while turning on power switch.

there's a toner waste colection unit that needs to be replaced
before you can proceed with self test. It's usually a small gray bottle full
of
expended toner. You can try reusing the bottle after it's emptied, but first
look
to see if there's a small fuse. If you find a small fuse - you will need to
replace it
to use this bottle again. There's usually a spare kept on the developer unit
or
toner cartridge. Please do not save wasted toner - old toner has lost most
of its triboelectric charge and will cause more problems than it's worth.

Did either printer show "on-line" status before trying to print?

You can just turn the power off, then connect them. It's just wiser to
unplug
to minimize further problems while troubleshooting your current problem.
Good luck -and don't hesitate to contact me for further help.
