Stapling Unit
When the stapling motor turns forward, the clinch arm lowers. The
stapler then moves upward to drive a staple into the paper and the
clinch bends the staple end over. The stapling motor then turns
backward, raising the clinch arm and lowering the stapler. The
stapling mechanism staples in the rear corner.
Staple Sheet Empty Detection
The staple empty detecting sensor detects whether or not a staple
sheet is in the staple cartridge. When the number of staples left in
the staple cartridge reaches approximately 40, a staple-sheet-empty
condition occurs and displays on the printer operator panel. If a
staple-sheet-empty condition occurs during a stapling sequence, it
displays after the stapling sequence completes. After a new staple
cartridge has been loaded, the stapling motor energizes until the
staple empty detecting sensor detects a staple sheet. After the
staple sheet is detected, the stapling motor energizes once again.
