3.10.3 Reset and Feed Buttons
If the printer ever malfunctions and does not respond to a request to print, you may need to
either reset the control board, or print a self-test. Before these functions can be used, you will
need to know where to find them. The reset and feed buttons are located at the top right hand
side of the CPU board, to the right of the "Setup/operate" switch. The names are written
below each button. When the reset button is pressed, the printer control board and print
mechanism will go through a forced system reset. This will clear up any failures due to
electronic error. If you press the feed button and hold it, the paper feed motor will feed paper
through the side of the Wash Select II door. The paper will stop feeding once you let go of the
button.
3.10.4 Manually Printing a Self Test
If you ever question whether the system is functioning properly, you may have the system
print a self-test page. This report is internally generated and will cycle through each available
character. If the test prints completely and the printing is legible, this is considered a passed
result.
To begin printing a self-test, press both the reset and feed buttons simultaneously for at least
one second. After at least one second, let go of the reset button only, while continuing to hold
down the feed button. The printer will begin to print a complete self-test.
