 Paper cannot be fed, although there is still paper left in the
cassette.
Contamination of the paper feed roller may prevent some sheets
of paper from being picked up.
Use Scotch tape to remove dirt on the paper feed roller.
 To increase the life of the Li-ion battery:
· We recommend discharging the Li-ion battery completely before
recharging it. Avoid recharging the battery frequently before it is
completely discharged. *
· Storing the rechargeable Li-ion battery in a location exposed to
high temperatures will cause it to deteriorate. Do not store the
rechargeable Li-ion battery in a location exposed to high
temperatures (such as inside a closed car under a hot sun) or
direct sunlight.
· If you do not intend to use the printer for a long period of time,
remove the rechargeable Li-ion battery from the printer, and
then store the battery in a cool, dark place (at a temperature of
20 °C/68 °F or less) to maintain performance. As the battery
discharges naturally, charge it once every three months while
storing it in a cool, dark place. *
* Caution: About the battery level
When the charging indicator light repeats flashing once, the
battery level is less than 30%.
· The battery connector should not be frequently unplugged and
reconnected, otherwise it may be damaged or the battery cord
may break. The battery must only be removed when replacing
it at the end of its service life, or when the printer will not be
used for a long period of time.
