Entering Test Print Mode
This mode is entered by pressing KEY 1 while turning the power switch ON and then releasing KEY 1 within three
seconds. The LCD will display the following message.
Caution:
The printer will enter user settings mode if KEY 1 is held down for more than three seconds.
After entering test print mode, message
[1]
is shown on the LCD while the printer is warming up. Message
[2]
is
displayed when the printer is ready to print.
“TEST” is shown on the bottom row of display when the printer enters test print mode. The number of test patterns
printed (“000058”) increases by one each time a test pattern is printed. “00000000” shown on the display on the
display does not mean anything and should be ignored.
Note 1:
When test print mode is entered, the scanner motor in the ROS assembly begins running and continues
running at a fixed speed.
Note 2:
The number of test patterns printed is displayed as a decimal number. After “999999” test patterns
have been printed, the display returns to “000000”.

Operation

is shown), the printer will begin printing when KEY 0 is pressed
and will continue printing test patterns until it is stopped.

If KEY 0 is pressed while the test patterns are being printed, the printer will stop printing the test patterns after the
test pattern currently being printed has been generated.

printing test patterns until it is stopped.
Warning:
Print only after the covers have been properly installed.
