Rolling ASCII test
The Rolling ASCII Print Test produces a continuous printout of all 96 ASCII characters in a
rolling pattern in whatever typeface is selected (ML5521ECO default = Utility; ML5591ECO
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!
Wide carriage Model ML5521ECO/ML5591ECO:
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
“Menu mode” on page 41 for more information.
