Troubleshooting Tips
Multimeter Probes
The connectors within the LaserWriter 600/630 are very small
and require sharp needle-point probes to make good contact. Do
not use probes that do not make proper contact. To see whether a
set of probes works properly, test resistance at connector J210
on the DC controller board in the manner described below (the
cable must connected to the board).
Set your multimeter to resistance and insert the probes at pins 1
and 10. If the reading indicates continuity then the probes are
making good contact. If the reading indicates infinite resistance,
then the probes do not make contact and should not be used with
this printer.
