Rolling ASCII Test
Wide carriage Model ML5521:
If you are using 8.5 inch paper to run the tests, make sure the paper
width selection in the printer menu is set to 8.5 inches. Otherwise,
printing on the platen may damage the printer. See the chapter on
"Menu Mode" for more information.
The Rolling ASCII Print Test produces a continuous printout of all 96
ASCII characters in a rolling pattern in whatever typeface is selected
(default = LQ Courier).
The top of the printout shows the Printer Model, Emulation, Country
Code, and Firmware Revision Level.
Make sure continuous forms paper is loaded.
1. Turn the printer OFF.
2. Press and hold the QUIET/TOF key while turning the printer
back ON. (If the printer comes on without starting the Rolling
ASCII test print, you did not hold the QUIET/TOF key long
enough.)
The printer prints the rolling ASCII text continuously.
3. Press SEL to end the test.
CAUTION!
