Before You Begin
This section describes the procedures that the service technician should know before servicing the
machine. Most of the parts of the machines in this series are identical and interchangeable. However,
please note that the main boards of these machines are not the same.
• Printer. Main board has no connectors for the flatbed scanner or ADF.
• 3in1. Man board has flat connectors for the flatbed scanner only (not ADF).
• 4in1. Main board has flat connectors for both the flatbed scanner and ADF.

the Smart Organizing Monitor. This procedure is not described in this service manual.
