Hi everybody! Today, my LC II give me some troubles. When i try to print with my ImageWriter, Os 7.1 give me error type -21. If i go into Apple->chooser the ImageWriter is not selected and if i selected it the printer works. But if i shoot down the LC i have the same trouble... Someone can explain me why? How can i resolve?

Could be a dead PRAM battery. The PRAM holds some system settings and if it dead, with will reset everything back to defaults when the computer starts.

Fix of course would be to install a new battery.
