Principles of Operation
C6 Finisher Function 1 Signal
This is a 5 VDC signal that is sent from the printer to the finisher. This
signal is normally High (Off) and active Low (ON). C6 signals the fin-
isher to begin specific operation for Function 1 and continue until the
signal is removed. Finishers can use the C6 signal to perform specific
operations such as paper size changes and other operations. Currently
the FusionPunch II does not use this signal as an end Device, but can
support it to down-line finishers.
C7 Finisher Function 2 Signal
This is a 5 VDC signal that is sent from the printer to the finisher. This
signal is normally High (Off) and active Low (ON). C7 signals the
finisher to begin specific operation for Function 2 and continue until the
signal is removed. Finishers can use the C7 signal to perform specific
operations such as paper size changes and other operations. Currently
the FusionPunch II does not use this signal as an end Device, but can
support it by routing it to down-line finishers.
Paper Path (Sequence of Operation)
Job Released
Once a job has been released, the printer must have the following Sta-
tuses from the FusionPunch II (these Statuses are specified by the
FusionPunch II Personality Profile) in order to start printing to the fin-
isher.
S0, S1, & S2 must be ON (High)
When all of these signals are ON (High), the printer will start up and
send the C2 signal to the FusionPunch II. When the FusionPunch II
receives the C2 signal, it will start the Document Transport Motor, the
Punch Motor, and be ready to accept paper.
Principles of Operation
Printer Exit Sensor / FusionPunch II Entrance Sensor
As the lead edge of a sheet of paper covers the last sensor in the printer,
the printer sends the C0 signal to the finisher. When the FusionPunch II
receives the C0 signal from the printer, the Entrance Sensor has 330ms
to see the lead edge of that sheet of paper and send a signal back to the
Little Star Controller PWB. If the Little Star Controller does not see a
signal from the Entrance Sensor within 330ms after the C0 signal has
been received, the FusionPunch II will turn OFF (Low) the S1 signal
(Faulted Signal) and display Jam at Entrance Sensor on the Punch Con-
trol Panel LCD. If the Entrance Sensor does send a signal back to the
Little Star Controller within the 330ms, the sheet of paper has 200ms
from lead edge to trail edge to clear the Entrance Sensor. If the sheet of
paper blocks the Entrance Sensor longer than 200ms, the FusionPunch
II will turn OFF (Low) the S1 signal and then display Jam at Entrance
Sensor, on the LCD.
When all requirements are met as specified above, the sheet of paper
will begin to make its way to the Document Transport Sensor 1
(explained below).
Note: The Little Star Controller is tracking the C0 signal (Sheet Exit)
and the sheet of paper associated with it. This will ensure that the sheet
is completely processed and the S3 signal is sent back to the printer at
the right time and on the correct sheet of paper.
If the sheet of paper is the last sheet of paper in a set, the printer will
send the C0 and the C1signals. If the Little Star Controller receives a C1
signal it will track that sheet of paper to ensure that the next set (Com-
plete Book) is offset stacked correctly.
