Rolling ASCII Test
Important!
Wide carriage Model ML691: 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. 
The top of the printout shows the Printer Model, 
Emulation (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.
