Cautions in handling the recording paper (thermal paper)
• Use only the paper specified by SHARP.
• Do not unpack the thermal paper until you are ready to use it.
• Avoid heat. The paper will 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 the direct sunlight
Contact with glue, thinner or a freshly copied blueprint.
Heat caused by friction from scratching or other such means.
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.
When the journal paper roll comes near the end or is not loaded, the machine senses this condition and sounds
an alarm, displaying the error code “E04”. At this time, clear the alarm with the
c
key and replace the paper roll
as soon as possible. The following entry can be made after clearing the alarm. However, since this function
works each time one transaction is completed, the alarm sound will be emitted again as the following transaction
is completed unless the paper roll is replaced.
• The sensing position depends upon the size of the paper tube.
Therefore, it is advisable to use paper rolls - whose paper tube is
18 mm in O.D. and 12 mm in I.D. - specified by SHARP.
• If the sensing occurs too early or late, contact your dealer.
