The tester runs the printer independently to test operation of printer and options (duplexing unit
and envelope feeder). It has three uses which are outlined below;
a. Commands the printer to print out solid black, horizontal lines, vertical lines and solid blank
images. It can also select the pick-up and delivery trays and simplex and duplex print.
b. Monitors the status of the sensors, and forcibly operates the various solenoids and motors.
c. In the event of a printer failure, the error information sent from the printer to the video con-
troller (external device) can be displayed on the tester LED.
Note: This manual covers the basic operation of the printer driver tester. For more defailed
explanation please refer to the operation manual attached to the tester.
