Main Switch Functions

Power ON: Push once while the printer is OFF.
Power OFF: Push twice quickly.
Manual Form Feed: With power ON and paper inserted, press and
hold the main switch to feed (or eject) paper. In order to assure that
printing is complete before permitting a form feed, manual form feeds
cannot be performed for five seconds after the printer has received any
data. The button must then be held down for 1-1/2 seconds to start the
form feed.
Charge the Battery: With the printer off, push the main switch and
hold it down for two or more seconds until the POWER indicator
begins to blink. The POWER indicator light continues to blink until
charging is complete.
To Power Off During Charge Mode: Push the main switch twice
quickly (same as when in normal operating mode).
Service Mode: After powering the unit on, press and hold for 2
seconds until the DATA LED turns red. In this mode you may initiate
self test printing (see Chapter 5) or head cleaning (see Chapter 4).
