910.x Loader: Sheet stack is empty
Description
Lifting table
The top-most position of the sheet stack is regulated automatically. If no more sheets are detected (sheet stack is empty), the lifting table no longer moves up.
The lifting table with the sheet stack is not yet in the automatic position for height regulation.
Remedy
- If there are only individual sheets or no sheets in the lifting table → add sheets.
- Check the mechanical settings (sensor position) of the lifting table.
- Check the feedback control of the upper edge of the stack.
- Check the digital input.
