I have an apple laserwriter II (actually I have 3) that are giving me problems. After I print a page the paper out light and the paper jam light both start flashing. They will go of when I cycle the power. I think I fixed this problem before by replacing the fuser and another part but I can't remember. Does anyone know how to fix this. Thanks

I needed to get my "main control" board replaced to clear this.

IF IT IS ONE OR THE OTHER, IS THERE A WAY TO TELL WHICH ONE IS AT FAULT?

Commented:
Well the way I used to do it is just by trying one part then another...but I can see where this would be a problem if you dont have the parts to swap.

To check the fuser, use an ohmmeter.  Check the two white wire connections on the right side of the fuser.  Resistance should be less than 5 ohms.  But, if the page that prints doesn't rub and smear, fuser is probably ok.  That leaves either a bad connection or a bad AC power supply.  Check the fuser connection to the printer body on the right side (under a black cover).  If the plastic is broken, the male plug on the fuser may not make good contact with the female side.

Also, after getting the 2 red lights, turn the printer off for 20 minutes to let the capacitor drain.  That may reset an intermediate problem.

Since you have 3 printers, have you tried to switch parts?

Finally, check the two solenoids that control the paper rollers.  They have a foam material to silence them.  The foam gets sticky with age and cause the solenoids to stick.  That can really mess up the printer's paper control.
