NOTES
•
A paper check is performed before printing. If paper is set, the print test is executed; if
no paper is set, the ERROR pop-up window is displayed. If you select to continue
printing, paper is automatically inserted by the ACF and to execute the print test.
•
Pressing the CANCEL key during printing will stop the test (paper is advanced), and
return the display to the Self Test menu.

If a serial number has not been input before starting the test, the pop-up window will
prompt for the serial number; either enter the serial number, or press RETURN to start
the test. If a serial number is entered, it will be printed on the first line of the test.
