SELF TEST

The self test mode can be set by the DIP switch 1-3. To set, first turn off the power to the printer and then change the DIP switch setting. When the power is turned back on, the new setting automatically comes into effect. To exit from the self test, turn off the power and reset the DIP switch.

The interface board first checks the RAM condition. After checking the RAM, data in the range between <3&H to <3!bH is sent to the printer and printed. The print out is only 80 columns wide.

Note

It takes some time to check the RAM before test printing.
