Electrical connection
The printer automatically detects the presence of the bypass
transport and third-party finishing devices when it is powered up.
The system also begins monitoring the interlocks (physical links)
between the bypass transport and the finishing device. It then
starts interface communications.
After a sheet of paper passes through the bypass transport to
the external finishing device, the printer loses all record of it.
Communications between the printer with bypass transport and
the finishing device consist of command and status signals.
Command signals NPS/IPS can send three command signals to third-party
finishing devices:
• Cycle up: The printer is powered up and signals the finishing
device to power up
• Sheet exit: A sheet of paper has entered the finishing device
• End of set: The last sheet of a print job set has been sent
Status signals The third-party finishing device can send five status signals to
the NPS/IPS:
• Sheet delivered: A sheet of paper has been successfully
delivered to the finishing device.
• Set delivered: A print job set has been successfully
delivered to the finishing device.
• Offline: The finishing device has no power or is not
connected to the NPS/IPS.
• Full: The finishing device is full and cannot accept more
sheets.
• Faulted: The finishing device is jammed or faulted and is not
ready to accept sheets of paper
