Printing test pattern
Before performing the printer's self test, be sure the ribbon cassette and paper are properly
installed in the printer. The self test prints a continuous pattern of printable characters (ASCII
character pattern) in either draft or letter quality (LQ).
While test printing is executed, the ON LINE lamp blinks and the LCD indicates “SELF TEST”.

printer is already turned ON, the LQ self test may be performed by pressing both the LF and
ON LINE keys simultaneously together with the RESET key.
