Self-Test Printing - Epson C82312 Series User Manual

Self-test printing

When the jumper is OFF, the interface card operates
normally. When the jumper is ON, the printer starts self-
test printing. The printout is always truncated at 80
columns.
To stop self-test printing, turn the printer power off and
set the interface card jumper to the OFF position.
