the printer. It includes the following connectors:

The Phaser 440 rear panel also features DIP switches to control certain aspects of
the printer’s imaging. You can also use the DIP switches for controlling the
self-tests of the printer’s image processor board. Refer to the Section 6 topic
“Image processor self-diagnostics” on page 6-31.
Health LED
A health LED indicates the status of the printer.

SIMMs or any of the interface ports. When a soft error occurs, the
printer automatically prints a startup page listing the error.
