Engine test print
The engine test print is used to confirm whether the printer operates correctly or not. It is performed
by the engine controller.
If a malfunction occurs in the printer, perform an engine test print while the printer is in STBY mode
and then press the test print switch (on the rear side of the printer) once. A one-page test pattern of
horizontal lines will print as shown below.
