Note: When troubleshooting, or prior to making any adjustment to
print quality, always be sure:
•
The printer is installed on a level rigid surface.
•
The OPCs are never exchanged. Do not exchange a black OPC
for a color OPC, as they have different surface phase counts.
•
Radar Page is always used when adjusting print registration.
