4. Cutter starts the cut.

5. Cutter completes the cut when it reaches the left side of the machine.

6. Cutter return sensor turns ON > Cutter motor drives the cutter back to its home position on the right.

registration position.

Operation Sequence When the Second Roll is Set

Here is a description of what happens when roll paper is already loaded and the leading edge of the

paper is at the registration standby position. This sequence is executed when:

• Roll Unit 2 (optional roll unit) is installed.

• Both roll units are installed, but the paper for the roll unit selected for the job is not at the

registration standby position.

At the start of the job, the paper at the registration standby position must be retracted so that the paper

from the other roll can be fed for printing.

1. The roll paper feed motor of the roll with paper at the registration standby position > ON reverses

at 120 mm/s.

2. The vertical motor > ON reverses at 100 mm/s. (The difference in the motor speeds keeps the

paper taut).

3. The pre-registration sensor > OFF and starts a pulse count.

4. Once the paper has fed downstream back into the roll unit paper path, the pre-registration sensor

stops the reverse feed.

5. The roll unit clutch, roll paper feed motor, and paper release sensor go off and the paper stops.

6. The paper is now at the paper feed standby position 51.5 mm downstream of the pre-registration

sensor, and the path is open for paper from the other roll to feed.

At the end of the job the cutter unit cuts from right to left. The circular cutter leaves its home position on

the right, cuts the paper as it moves to the left, and then drops below the paper and returns to its home

position on the right.
