SP1902 001 displays the web consumption. When the web consumption exceeds the value set with SP1-902-4 (Web Near End), the machine indicates web near-end on the operation display.

The machine still operates while the actuator [A] remains above the web end sensor

[B]undetected. The actuator arm of the actuator remains in contact with the supply roller [C] and gradually lowers as the amount of web on the supply roller grows smaller as it is fed to the take-up roller [D] above.

When the web runs out, the actuator drops into the web end sensor at [E] and the sensor signal to the CPU displays SC550 on the operation panel display. In this condition, a technician must install a new oil supply and cleaning web, and then reset SP1902 001 to 0 to clear SC550.
