Staple sheet empty detection
• Staple empty detection sensor 1, 2 detect whether or not there is a staple sheet still left.
• When the number of staples left in the staple cartridge becomes about 20, a staple sheet
empty condition results, causing a corresponding empty message to appear on the con-
trol panel.
• When the empty condition is detected, the corresponding empty indication is given on
the control panel. At the same time, the Stapling Unit moves to the front.
• When a new staple cartridge is loaded, the stapling motor is energized until the self-
priming sensor detects a staple, which results in the staple to be fed up to the stapling
position.
