Rolling ASCII Test
Important!
Wide carriage Model ML621: If you are using 8.5”
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 Chapter 4: 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 (Microline, Epson, IBM compatible),
Firmware (F/W) Revision Level, Flash Loader (LD)
Revision Level, and Part Number.
Make sure continuous forms paper is loaded.
Turn the printer off.
Press and hold the SEL + LF/FF keys while turning
the printer back on.
When only the SEL indicator is blinking, hold
down the LF/FF key and press the SEL key.
The printer prints the rolling ASCII text page
after page.
Turn the power OFF to end the test.
