THE BATTERY
Remove / Install Battery
Please power off the printer before removing the battery. Please refer
to the bottom picture of the printer in the previous pages. Pull down the battery
lock to remove the battery. The screw on battery has nothing to do with this
operation. The battery used to power the mobile printer is identical to the one
for its host system – mobile terminal MT-2000 series and the screw on battery
is used for application in MT-2000 series only.
To install the battery, you have to insert the other end of the battery
first then push the battery till it clicks in the battery lock. The printer is then
ready for operation in option carry bag or any other appropriate carrier.
Battery Charge by Power Adaptor
Please refer to the right side picture of the printer in the previous
pages. Use the small charger (DC 12V 15W) delivered with the MT-2000
series or purchase an additional option one (P/N: 21972012120 for US market).
Check the information on the option power adaptor that if it matches the
domestic power supply specifications. Connect the power adaptor to a power
outlet and connect its output to the battery charge connector on MP-300.
Please note that prior to this charging operation the printer should be powered
off and please do not operate the printer during charging!
Battery Charge by Dock Station
Since the battery used for MP-300 is identical to the one for MT-2000
series, it is most convenient to use the option dock station (cradle, DS-100)
with its large power adaptor for MT-2000 series to charge the battery if this
option is purchased.
When to Replace / Recharge Battery
1. For a new battery, it must be completely recharged before first use. It is
delivered with little reserved power for better battery life.
2. When the voltage measurement in self-test (described later in
APPLICATION GUIDE) reports to be near 7.2 V or lower.
3. When the printer gives occasional beep and “ERROR” indication.
