C. Test Print
The test print is divided into two types: engine test print and controller test print.
If a malfunction occurs in this printer, make a test print and assess the abnormality of the
printer.
1. Engine test print
Execution of a test print prints the test print pattern (vertical lines) shown in Figure 4-1-2.
A test pattern can be printed by pressing the test print switch on the back of the printer (refer
to Figure 1-4-2) once when the photosensitive drum is stationary and the printer is in the
STANDBY mode. Test pattern can be printed continuously as long as the switch is held down.
The paper can be picked-up only from the built-in cassette and the option cannot be used when
making a test print.
