printUSB Power Switch:
The printUSB power switch can be pressed for 1 second to turn the
printUSB on or off anytime except during the startup process. After
pressing the Power Switch to turn on the printUSB, it should be
allowed to finish the 35 second startup process before attempting to
press the power switch again. Interrupting the boot process can cause
an abnormal state and should be avoided.
Reset the printUSB by pressing the Power Switch for 10 seconds. A
reset is not required during normal product operation. However, a Reset
can be performed after a firmware upgrade or in the rare case of an
abnormal state.
printUSB Charging:
Connect the printUSB Micro USB Cable to an USB AC Adapter. The
printUSB battery requires a minimum of 4 hours to charge with nothing
else connected to it. A fully charged battery will provide approx. 1 hour
of printing and retain the charge for up to 3 weeks in Power OFF mode.
Power save feature turns the unit off after 10 minutes of inactivity when
running on battery.
Note: A mobile device may be charged when the printUSB is charging
by connecting the mobile device (phone or tablet) to the printUSB
Mobile Device USB connector. When a mobile device is being charged
through the printUSB, a full charge time for both devices may require
12 hours or longer. Note: Tablet screens should be off to facilitate a
faster charge.
