Controller board service check
Service checks which involve measuring voltages on the power supply should be performed with the printer
positioned on its rear side.
Note:
When making voltage readings, always use frame ground unless another ground is specified. See the
wiring diagram in the back of the book for more information.
Warning—Potential Damage:
Do not replace the control panel and controller board at the same time. Each
card contains the printer settings. When either of these cards is new, it obtains some of the settings from the
other card. Settings are lost when both are new and replaced at the same time.
