Principles of Operation
Paper Path (Sequence of Operation) Continued
Punch Sensor / Exit Sensor
When the lead edge of the sheet of paper is under the Punch Sensor, a
number of things happen as follows:
1. 60ms after the lead edge of the sheet of paper is under the
Punch Sensor, the Little Star Controller will turn ON the Punch
Clutch Solenoid. It will then hold the Punch Clutch Solenoid
ON for 50ms.
Note: The Punch Clutch on Set is defaulted to 50ms; it can be changed
in the Diagnostics function of the Clutch on Set in intervals of 5ms. The
Punch Clutch on Set is directly related to steps 2-6. If the value of the
Clutch on Set is changed, the time at which events occur in steps 2-6
will change according to the amount that the Clutch on Set value has
changed.
2. At the time the Punch Clutch Solenoid is turned OFF, the Little
Star Controller will turn ON the Stacker Tapper Solenoid and
hold it ON for 60ms.
- If a Second Stacker is active, then the Stacker 2 Tapper
Solenoid is activated 20ms after the lead edge of that sheet of
paper reaches the Bypass Sensor. It will remain active for
60ms.
3. 30ms after the Punch Clutch Solenoid is turned OFF, the Little
Star Controller will turn OFF the Back Gauge Solenoid and the
Back Gauge Finger will drop allowing the sheet of paper to
start moving to the Exit Sensor and to the Stacker.
4. At the same time the Back Gauge Solenoid is turned OFF, the
Little Star Controller will turn ON the Stacker O-ring Motor
and hold it on for 325ms.
- If a Second Stacker is active, then the Stacker 2 O-ring
Motor is activated 20ms after the lead edge of that sheet of
paper reaches the Bypass Sensor. It will remain active for
325ms.
5. If the sheet of paper was the last sheet in a Set, the Little Star
Controller would have received the C1 signal when the sheet of
was exiting the printer. If the sheet has a C1 signal associated
with it, then on the next sheet of paper, after the time delay, the
Little Star Controller will turn the ON the opposite Offset Sole-
noid and hold it on for 150ms.
NOTE:If a Second Stacker is active, the time shift will
have longer time delay.
6. 30ms after the Back Gauge Solenoid is turned OFF, the Little
Star Controller will turn ON the Sheet Eject Solenoid and hold
it ON for 30ms.
Punch Sensor / Exit Sensor (Continued)
Once all of the steps above have occurred correctly, the trail edge of the
sheet of paper has 250ms to clear the Punch Sensor. If the trail edge of
the sheet does not clear the Punch Sensor in the 250ms, the Fusion-
Punch II will turn OFF the S1 signal and display Jam at Punch Sensor,
on the Punch Control Panel LCD.
After the trail edge of that sheet of paper clears the Punch Sensor, the
Little Star Controller will turn ON the Back Gauge Solenoid to prepare
to stop the next sheet of paper to be punched.
The sheet has 330ms from the time the lead edge gets to the Punch Sen-
sor to the time the lead edge gets to the Exit Sensor. If the sheet of paper
does not make it within the 330ms, the FusionPunch II will turn OFF the
S1 signal and then display Jam at Exit Sensor on the LCD.
