About Sleep Mode - Avery Dennison Mobile Work Station (MWS) Monarch 9876 Operating & Maintenance Instructions

To conserve the battery, make sure the Mobile Work Station's power switch
is turned OFF when not in use OR when charging the batteries. For optimal
(shortest) charging time, turn off the MWS and printer while charging.
If you need to finish a batch, you can print while charging, as long as the
batteries are not too depleted. However, printing while charging is not
recommended on a frequent basis.
If the printer will be unused for extended periods of time, we recommend
leaving the printhead unlatched.
If the printer's green power light blinks, you need to recharge the battery.
There is a small reserve of battery power to continue printing after the
green power light begins blinking.
You must recharge the battery when you see error 762 or "Battery Dead"
on the display because the printer is in a "lock-up" condition and does
not print until the battery is recharged.
The printer may slow down if the battery voltage drops below a certain
level. The printer continues to print at the reduced speed until the
batteries are charged and the printer is turned off and then back on.
See "Battery Life" in Chapter 3 for more information about charging the
batteries.
A b o u t S l e e p M o d e
If the Monarch printer is inactive for longer than 30 seconds, the printer
goes into sleep mode to conserve battery power. While in sleep mode, the
display backlight is turned off to conserve battery power. Once the printer
"wakes up," the backlight turns on.
To "wake up" the printer, press any button on the control panel. The buttons
are active during sleep mode, so if you press Escape/Clear, the printer
"wakes up" and you enter the offline menu mode. You can also send any
data to the printer to wake it up. You do not lose any data sent to the
printer during sleep mode.
