3.3 Detection of Abnormal Status � Cover Open/Close Detection The STP cover open switch turns OFF when the cover is opened. Since the switch is connected to the power supply, the power supply to the STP is cut when the switch turns OFF. For this reason, all the operation is disabled while the cover is open. When the STP cover is closed, the delivery of the power supply is resumed to light the STP power lamp and enable stapling. Staple Empty Detection Upon detecting a staple empty state, th

MECHANICAL DESCRIPTION 4.1 Mechanism Drawing Paper set STP paper set sensor STP 04-01-01 4.2 Staple Operation The staple operation of the STP is performed only by the rotation of the STP motor through the combina- tion of the gears and cams. The loading of paper is detected when the paper detection lever is pushed. When paper is loaded into the stapler, the paper detection lever is pushed causing the STP paper set sensor to detect the presence of paper. When the presence of paper is detec
