DFA (continued)
S0 Online/Offline Signal
The Online/Offline signal is a 5 VDC signal that is sent to the printer to
notify the printer that the finishing device is ready to accept paper.
When the FusionPunch II turns this signal ON (High), the printer then
knows the FusionPunch II is ready to accept paper. When the finishing
device turns this signal OFF (Low), the printer then understands that the
finishing device is NOT ready to accept paper. The printer then waits
for this signal to come back ON (High) before it will start printing to a
finisher, as long as the other two signals (Faulted & Full) are ON
(High). If this signal is turned OFF (Low) while the printer is running,
the printer performs a Hard Shut Down where it stops printing instantly
and usually purges remaining sheets in the paper path out to the Top
Tray of the printer. The printer also displays a message stating "Clear
External Finisher to run jobs to the Bypass Transport", or "External Fin-
isher Not Ready".
S1 Faulted Signal
This is a 5 VDC signal that is sent to the printer to notify the printer that
the FusionPunch II is NOT faulted or jammed. When the FusionPunch
II turns this signal ON (High), the printer then knows the device is NOT
faulted or jammed. When the FusionPunch II turns this signal OFF
(Low), the printer understands that the finishing device is faulted or
jammed and cannot accept paper. The printer then waits for this signal
to come back ON (High) before it will start printing to the finisher, as
long as the other two signals (Offline & Full) are ON (High). If this
signal is turned OFF (Low) while the printer is running, the printer
performs a Hard Shut Down (stops printing instantly and usually purges
remaining sheet in the paper path out to the Top Tray of the Printer).
The printer also displays a message stating External Finisher Jam or
Jam in Area 20.
Principles of Operation
S2 Full Signal
This is a 5 VDC signal that is sent to the printer to notify the printer that
the finishing device is NOT full. When the FusionPunch II turns this
signal ON (High), the printer then knows the device is NOT full. If the
printer is running when the punch turns this signal OFF (Low), the
printer then understands that the finishing device is full and can only
accept a certain amount of paper, as specified in the Personality Profile.
The printer then does a Soft Shut Down (does not stop instantly, contin-
ues to print a specified number of sheets to the finisher, then shuts
down). The printer also displays a message stating "External Finisher
Full". When this signal comes back ON (High), the printer will start
printing to the finisher automatically as long as the other two signals
(Offline & Faulted) are ON (High).
C0 Sheet Exit Signal
This is a 5 VDC signal that is sent from the printer to the FusionPunch II
on every sheet of paper, as the lead edge (specified in the Personality
Profile) covers the last sensor in the printer. This signal is normally
High (Off) and active Low (ON). The FusionPunch II uses the C0 sig-
nal to recognize that a sheet of paper is coming and also to track every
sheet through the finisher for Error Recovery.
C1 Set Exit Signal (End Of Set Signal)
This is a 5 VDC signal that is sent from the printer to the finisher on the
last sheet of every set, as the lead edge (Specified in the Personality
Profile) covers the last sensor in the printer. This signal is normally
High (Off) and active Low (ON). The FusionPunch II uses the C1
signal to recognize that the last sheet of paper in a set is coming. It will
then know when the Set is complete and will be able to offset the stack
correctly.
