Original conveyance process The ADF consists of an original feed section, conveyance section, reversal section, and original exit section. The original face up on the original feed tray, is fed from the topmost original. The fed original is not conveyed to the original glass. Instead, it is read when it passes the ADF glass placed in the conveyance path. The ADF operation consists of single side original copy mode, double side original copy mode, mixed original copy mode and Z-fold mode.
reversal section. The reversal roller and original exit reversal roller feed the original inside the reversal section. Original registration PS/1 (PS304) Original exit reversal roller Registration roller Original conveyance PS (PS306) Conveyance roller The original is read when it passes over the ADF glass. The original that has been read is ejected to the original exit section by the original exit roller, passing along the circumference of the original exit guide.
reversal roller is released for a specified period of time. The leading edge and the trailing edge of the original brush against each other at the original exit reversal roller. The next original is pre-fed if there is one.

Original feed/conveyance/exit section ADF unit explanation Composition Mechanism Mechanism Original feed Double feed prevention Original conveyance Original exit Original conveyance path selection *1 Original reverse and feed Original exit path selection *2 *1 Method Pick roller Feed roller Separation roller (SD301) is turned on/off to switch between the reversal section and the original exit section.
*2 Original exit path switching During the double side copy mode, the up/down movement of the original exit gate determines whether to eject the original, or to feed the original to the reversal section to scan it again. The exit gate drive SD (SD302) turns on/off during the double side copy mode. To scan the back side, the original exit gate goes down to convey the original to the reversal section.
The forward rotation of M301 releases the pressure on the original pressing plate. 1 Operation During the single-side original copy, the conveyance switches to low speed when the specified time has passed after PS305 (original registration /2) has turned on. During the double-side original copy, the reverse gate opens and the original passes through the reverse gate to be conveyed to the reversal section at high speed.
d Scanning the last sheet of original When PS301 (last original) turns off while scanning is in progress, currently scanned original is processed as the last original. The pre-feed of the original stops, and with PS302 (original setting) turned off, the original feed tray is detected as empty. M301 (original feed) and M302 (original conveyance) stop when the specified time has passed after the original has passed through PS303 (original exit) and original ejection has completed.

1 Operation a Original ejection operation During the single side copy mode and when copying the front side in the double side copy mode, the original exit gate lifts upward because SD302 (exit gate drive SD) is turned off. Therefore, scanned original is ejected to the original exit tray by the action of the original exit roller. PS303 (original exit PS) detects the original ejection.

Paper conveyance path The finisher consists of five paper paths, as shown in the diagram below. Sheets are turned over by the MFP's exit page inverter, and then passed to the finisher. The finisher has two paper entrance connections: one from the MFP, and the other from PI-110 (optional).
In the non-sort mode, the gate is set to the position to carry paper to the main tray. Each sheet, delivered from the MFP, is carried to the main tray through the gate.
Sort and group modes In the sort and group modes, the gate is set to the position to carry paper to the main tray. Each sheet, delivered from the MFP, is conveyed to the main tray while the sheet is shifted by 30 mm to the rear. The shift roller of the shift unit performs the shift action. In the sort mode, even pages are offset. In the group mode, even numbered copies are offset.
In the sub-tray mode, the gate is set to the position to carry paper to the sub-tray. Each sheet, delivered from the MFP, is delivered to the sub-tray.
Staple mode For sheets of all sizes except A4, B5, and 8.5 by 11 1 The gates are set to the position to carry paper to the stacker. 2 If paper is larger than A4R, the paper exit opening will open. 3 Each sheet is carried to the flat-stapling stopper and its vertical position (feeding direction) is adjusted. 4 The horizontal position (width/direction) of each sheet is adjusted by the alignment plate/U. 5 When all necessary sheets are stacked, they are stapled with the stapler and the clincher.
1 The first set is stapled and delivered to the main tray in the same manner as sheets of all size except A4, B5, and 8.5 by 11. 2 As the front of the first set is being discharged, the stacker entrance roller stops and the bypass gate opens. The first sheet of the second set (and subsequent sets) is conveyed to the stacker entrance. 3 The bypass gate closes, and a second sheet is laid over the first sheet which is fixed by the stacker entrance roller.
Booklet mode 1 The gates are set to the position to carry paper to the stacker. 2 The paper exit opening opens. 3 The booklet stopper lowers to the stitch-and-fold position. The flat-stapling stopper is released as the booklet stopper lowers. 4 The paper is conveyed to the booklet stopper to line up sheets in the lengthwise direction. 5 The alignment plate/U and alignment plate/L line up each sheet in the widthwise direction.
Tri-folding mode 2 The paper exit opening opens. 3 The booklet stopper lowers to the stitch-and-fold position. The flat-stapling stopper is released as the booklet stopper lowers. 4 The paper is conveyed to the booklet stopper to line up in the lengthwise direction. 5 The alignment plate/U and the alignment plate/L line up each sheet in the widthwise direction. 6 The booklet stopper lowers to the first folding position, and the sheet is set to the first folding position.

Either of these modes can be selected on the control panel of the MFP.
B6 / 16K 3 holes MFP Letter / Legal / 5.5 by 8.5R / A5R / A4 Punch unit Rack Formation of a registration loop The finisher conveyance motor (M701) turns off temporarily to stop conveyance of paper when the specified time has passed since paper exit PS (PS37) detected the leading edge of the paper. Thus the paper is pressed against the entrance roller forming a loop to correct the bend. When the specified time has passed, M701 turns on to restart conveying the paper.
Correction of the punch position The punch unit positioned inside of the side edge of paper by 5 mm or 10 mm performs the following procedures to correct the punch position so that the punch is always centered on the paper. The punch position is corrected by moving the punch unit to and fro during conveyance of the paper. ● When finisher entrance PS (PS704) detects the leading edge of the paper, the punch unit is moved backward temporarily until the paper edge sensor detects the side edge of the paper.
