Scanning and image capture system (M577)
NOTE: This section is for the M577 printer only.
The scanner is a carriage-type platen scanner which includes the frame, glass, scan module, and a scan
control board (SCB). The scanner has a sensor to detect legal-sized media and a switch to indicate when the
document feeder is opened.
The document feeder and control panel are attached to the scanner. If the scanner fails, it can be replaced as
a whole unit. The scanner replacement part does not include the document feeder, control panel, or SCB.
