F17 Photocell in hopper blocked
The conveyor system has stopped.
The photocells in the hopper have been obstructed for more than 10 seconds with the prepress at its rear position.
The material distributor is inserted when a photocell indicates full hopper.
Check the photocells for blockage by dirt or by other material stuck in the hopper.
If the photocell is blocked by a large sheet, press and hold the [Conveyor on] button on the conveyor control panel for 5 seconds. This drives the conveyor belt so that new material may compress the large sheet and clear the photocell. Don’t overfill the hopper.
