CHAPTER 13 TROUBLESHOOTING
If the copier is used in highlands (low atmospheric pressure), images may suffer
from transfer faults. Try changing the setting of the DIP switch (SW1) to
highland 1, and see if the problem is corrected; if the problem still occurs,
switch SW1 to highland 2.
If the problem still remains thereafter, shift SW1 back to its normal setting, and
try to check other possible causes.
2. CPU PCB
