Operation Manual

Sleep Mode
If no lights are on or blinking, either the printer is in SleepMode, or the
power source has been disabled. In SleepMode, the lights automatically
turn off after 15 minutes of no activity. However, the printer remains ready
to receive data instantly.
Action: No action is necessary. A status light comes on the moment you
press the Front Panel Button, send data to the printer, or open the printer
door.
Hardware Error
If all the lights are on steadily, there is an internal problem that will not
allow printing.
Action:
1. If you have installed an additional memory card, try removing it. (The
memory card may be defective or installed incorrectly. See Appendix
D for memory card installation.)
2. Disconnect the power for 10 seconds, then reconnect the printer to the
the power source.
3. If all three lights go on steadily again, try disconnecting the power for
15 minutes.
Incompatible Memory Card Installed
If an incompatible memory card has been installed the printer will flash all
three lights simultaneously until the card has been removed. The
memory card must be a 70 nsec or faster (for example, 50 nsec) card.
Action: See Appendix D for memory card specifications.
