Running a printer operation check
Performing a printer operation check can help you to determine
whether the problem comes from the printer or from the
computer.
To print a printer operation check page, follow the steps below.
1. Make sure that both the printer and computer are turned off.
2. Disconnect the cable from the printer’s interface connector.
If you use the parallel interface, unlock the wire clips on both
sides of the interface connector and remove the ground
connector, if necessary. Then, disconnect the cable from the
printer’s interface connector.
3. Make sure that A4 or Letter size paper is loaded in the sheet
feeder.
