Operation Manual

Why does the printer not print when data is sent from the
computer?
You may have the printer deselected (the SELECT light is out).
Press the SELECT button.
If the SELECT light still does not come
on, even though the POWER light is on, turn the printer OFF and
check that the interface connection from the computer is secure.
Why are dots missing in my printout?
The headgap may not be set correctly. Try moving the headgap
lever to a lower setting. If that does not help, the printhead may be
damaged. Call for service.
Why does my ribbon come off?
• Make sure that the ribbon cartridge is seated properly.
• Ensure that the ribbon is properly located around the ribbon
guide, as
shown on the ribbon fitting instruction label.
How can I check the data that my computer is sending to the
printer?
By entering the hexadecimal mode. Hold the SELECT and FORM
FEED buttons down while turning the printer ON. All data sent to
the printer, including text
and printer commands, will be printed
in hexadecimal format. For example, this line of BASIC code:
LPRINT CHR$(27)
;"0"; CHR$(30); "12345";CHR$(10)
would print in this format;
lB 30 lE 31 32 33 34 35 OA . 0. 1 2 3 4 5.
To return to standard printing, turn the printer OFF then ON
again.
