CHAPTER 3. MAIN DRIVE SECTION
3. Paper Drum Rotation Position
The paper drum rotation position is checked by the Position T sensor.
The precise rotational position of the paper drum is checked by the main motor limit sensor
(encoder sensor) from the T-position.
The Paper Drum stops at 150 degrees from its T-position after the printing job is finished and
waits for next job. (
Refer to page 2-5 for the sketch of the Paper drum 150 degrees position from
the T-position).
4. Low Temperature Printing Speed Limit
When either one of the temperature sensors, one on the Mechanical control PCB and the other on
the Ink sensor PCB, detects temperature of 10 degrees Celsius or lower, the maximum Print drum
rotation speed will be limited to 100 r.p.m. The operation panel will indicate the message,
“Limited Print Speed”.
While the printing is in progress, even though the temperature exceeds 10 degrees Celsius, the
speed limitation remains until the Stop button is once pressed and the printing is restarted.
