X When storing the battery pack for long periods of time, keep it in a cool place. If possible, avoid
long-term storage in the fully charged state. It may affect the battery life.
X Clean the terminals of the battery pack regularly (wipe them with a dry cloth).
X In order to fully demonstrate the performance of the battery pack, charge the battery at room
temperature and the temperature of the battery pack ranging from 0 °C to 35 °C / 32 °F to 95 °F.
X Clean the terminals of the dedicated charger regularly (wipe them with a dry cloth).
X DO NOT connect the AC cable of the AC adapter or the charger to the power supply wall socket
which was already connected to any other devices which generate noise.
X High-print-rate printing might cause irregular printouts or generate loud noise. This is not a failure
in the printer, but an inherent paper phenomenon.
X Always use roll paper whose width is at least 4 mm wider than the print width.
