Cautions in handling the recording paper (thermal paper)
Use only paper as specified by SHARP.
Unpack the thermal paper just before you use it.
•Avoid heat. The paper begins to develop color at around 70 C.
•Avoid dusty and humid places for storage. Avoid direct sunlight.
The printed text on the paper can discolor under the following conditions:
Exposure to high humidity and temperature.
Exposure to direct sunlight.
Contact with glue, thinner or a freshly copied blueprint.
Heat caused by friction (scratching etc.)
Contact with a rubber eraser or adhesive tape.
Be very careful when handling the thermal paper. If you want to keep a permanent record, copy the printed text
with a photocopier.
Recording paper specifications
Be sure to use paper rolls as specified by SHARP.
The use of any paper rolls other than specified could cause paper jamming, resulting in a POS terminal
malfunction.
Paper specification
Paper width: 2.26 ± 0.02 in. (57.5 ± 0.5 mm)
Max. outside diameter: 3.15 in. (80 mm)
Quality: Thermal paper

• Be sure to set paper roll(s) prior to using your machine. Otherwise it may cause a malfunction.
Install the paper roll in the printer. Be careful to set the roll and cut the paper end correctly.
NOTE
If the leading end of the paper roll is fixed with paste or tape, the paper’s color development ability may
be lost in the pasted or taped area due to deterioration of the heat-sensitive color development compo-
nent of the paper surface. As a result, nothing may be printed in this area. Therefore, when setting a new
paper roll in the machine, be sure to cut off approximately one revolution (approx. 25 cm long).
