Hexadecimal Print-Out
Hexadecimal printing is a diagnostic feature which allows you to analyze all
the bytes transferred from the computer to the printer. Each byte transmitted is
printed in hexadecimal format, allowing you to check the data codes received.
Running a Hexadecimal Print-Out
NOTE: Make sure that the print head is inserted and that there is paper in the
paper tray. The hexadecimal print-out is started from a printer-off condition.
• Holding down the On-Line and Install Cartridge buttons, switch on the
printer. (Keep the buttons held down until printing starts.)
Any data now transmitted to the printer will be printed in hexadecimal format
(see example below); ESCAPE sequences are not executed. If there is no paper
in the printer, the On-Line indicator will start flashing. You must load paper
in the paper input tray and then press the Form Feed button.
To suspend the print-out temporarily:
• Press the On-Line button (pressing this button a second time will cause
printing to resume).
To exit from hexadecimal print-out mode:
• Switch the printer off.
When the print job has finished, check it to see that the hexadecimal codes
printed correspond exactly to what you entered on your computer.
