Paper Path (Sequence of Operation) Continued
Entrance Sensor / Document Transport Sensor 1
The sheet paper now has 330ms from the time that the lead edge arrived
at the Entrance Sensor to the time that the lead edge arrives at DT1
(Document Transport Sensor 1). If the lead edge of the sheet does not
make its way to DT1 within the 330ms, the FusionPunch II will turn
OFF (Low) the S1 signal (Faulted Signal) and then display Jam at
Document Transport Sensor 1 on the LCD. If the sheet of paper does
make it to DT1 within the 330ms, the sheet of paper has 200ms from
lead edge to trail edge to clear DT1. If the sheet blocks DT1 longer than
200ms, the FusionPunch II will turn OFF (Low) the S1 signal and dis-
play Jam at Document Transport Sensor 1 on the LCD.
Once all requirements are met as specified above, the sheet of paper will
begin to make its way to the Document Transport Sensor 2.
GBC FusionPunch II Service Manual
Document Transport Sensor 1 / Document Transport Sensor 2
The sheet of paper has no specified time in which it must arrive at DT2
(Document Transport Sensor 2). When the lead edge of the sheet of
paper arrives at DT2, the Little Star Controller PWB will turn ON the
Back Gauge Solenoid. This will bring the Back Gauge Fingers up to
stop the sheet in the Die, in order to be punched. Once the lead edge of
that sheet of paper passes DT2, it has 200ms to clear the sensor. If the
sheet blocks DT2 longer than 200ms, the FusionPunch II will turn OFF
(Low) the S1 signal and then display Jam at Document Transport Sen-
sor 2 on the LCD.
When all requirements are met as specified above, the sheet will begin
to make its way to the Punch Sensor (explained below).
Document Transport Sensor 2 / Punch Sensor
The sheet of paper will now proceed to the Punch Sensor. The Back
Gauge Fingers should already be up and ready to stop the paper under
the Die.
Note: There is no check for the sheet of paper to make it from DT2 to
the Punch Sensor within a specified time.
