DESCRIPTION OF OPERATIONS 3.1 DRIVE SYSTEM Feed motor drive section 3 Read motor drive section Exit/reverse motor drive section Fig. 3-1 3.1.1 Outline Originals are transported by the original feed motor, read motor and original exit/reverse motor. Each motor has a drive section for the following operations: Original feed motor drive section: Read motor drive section: picks up originals and drives the registration roller. transports originals and drives parts such as the pre-reading roller. Original exit/reverse motor drive section: exits and reverses originals, and drives the exit/reverse roller. The Original feed motor rotates reversely when the originals are being transported at the registration roller, compared to its rotational direction when they are being picked up. The original exit/reverse motor also rotates reversely when the originals are being reversed and transported, compared to its rotational direction when they are being exited. The read motor always rotates in a constant direction. © 2005 - 2011 TOSHIBA TEC CORPORATION All rights reserved MR-3018/3020/3021/3022 DESCRIPTION OF OPERATIONS 3-1 06/09 3.1.2 Original feed motor drive section Original feed motor Oneway clutch Pickup roller Feed roller Oneway clutch Separation roller Pickup Registration roller Feed Fig. 3-2 When an original is placed on the original tray and the RADF receives a feed request signal from the equipment, the feeding of the original is started. The original empty sensor detects the presence of the original, and then the pickup roller is lowered by the drive from the original pickup solenoid. The Original feed motor rotates, and the pickup roller and the feed roller then rotate in a normal direction (shown in a solid line in the figure) to guide the original into the transport path. Then the original is transported to the registration roller to be aligned. The original aligned with the registration roller is then transported by the reverse rotation of the Original feed motor (shown in a dotted line in the figure). A one-way clutch is installed inside of each gear of the feed roller and the registration roller, so these gears will not be driven in a reverse rotation. When the original empty sensor detects that there is no original on the original tray, the original pickup solenoid is turned OFF and the pickup roller is raised. The original pickup solenoid is the one can operate both suction and recovery.

Then the original is transported to a scanning start position by the intermediate transfer roller and prereading roller. The original transported to the scanning start position is then scanned in the scanner function of the equipment. When the data of the original have been scanned, the original is then transported to the original exit tray side by the post-reading roller. © 2005 - 2011 TOSHIBA TEC CORPORATION All rights reserved MR-3018/3020/3021/3022 DESCRIPTION OF OPERATIONS 3-3 06/06 3.1.4 Original exit/reverse motor drive section Gate solenoid Reverse flap Exit/reverse motor Exit Exit/reverse roller Reverse Fig. 3-4 When the data of the original have been scanned, the original is exited to the original exit tray by the exit/reverse roller driven by the exit motor (shown in a solid line in the figure). In the duplex scanning mode, the gate solenoid is turned ON and the reverse flap is lowered to switch the transport path to the reverse tray side when the scanning of one side of the original is completed. When the reverse flap is lowered, the original is temporarily transported to the reverse tray, and then the exit motor rotates reversely to return the original to the transport path switched for reverse operation (shown in a dotted line in the figure). The reversed original is aligned with the reverse registration roller, and then the other side of the original is scanned. When the scanning is completed, the original is exited to the original exit tray. MR-3018/3020/3021/3022 DESCRIPTION OF OPERATIONS © 2005 - 2011 TOSHIBA TEC CORPORATION All rights reserved 3-4 06/09 3.2 Original Size Detection The original tray width sensor, original length detection sensor, and original width detection sensors-1 and -2 work in combination to detect the size of originals. Original tray width sensor Original width detection sensor-1 Original width detection sensor-2 3 Original length detection sensor Fig. 3-5 3.2.1 Outline When an original is placed on the original tray, the width of the original is detected by the positions of the original width guides. Then the original width sensors -1 and -2 and the original length detection sensor detect the size of the original being transported. Based on the detection result of these sensors, the size of the original is finally determined. 3.2.2 Original tray width sensor The original tray width sensor detects the width of an original placed on the original tray. It is detected by the brush attached to the rack moving on the original tray width sensor, which is a board with the different length of the patterns written. This brush is moved as the original width guide is moved. Signals (TWID0S, TWID1S, TWID2S) are opened and shorted to SG by this movement. The combination of these short (= low level) and open (= high level) can determine the width of the original. Sizes detectable in combination of these open and short of the signals are as follows: TWID2S TWID1S TWID0S L H L L L H H H H L L L L H L Original width size (LT series) ST-R LD / LT 8.5 x 8.5 / LT-R / LG / 13"LG COMPUTER H (= high level): Open Original width size (A4 series) B5-R A5-R A3 / A4 A4-R / FOLIO B4 / B5 L (= low level): Short © 2005 - 2011 TOSHIBA TEC CORPORATION All rights reserved MR-3018/3020/3021/3022 DESCRIPTION OF OPERATIONS 3-5 11/12 3.2.3 Original width detection sensors-1 and -2 / Original length detection sensor The size of the original is determined by the detection performed in combination of the original width detection sensors-1 and -2 and the original length detection sensor, as well as the detection performed by the original tray width sensor.

A drive clock signal (FMOT-CLK) and rotation direction signal (FMOT-CW/CCW) are input to control the speed and direction of the motor rotation. When the level of the enabling signal (FMOT-Enable) is set to "L", motor current is turned OFF regardless of the state of other signals. For the excitation mode, either of 2 phase excitation, 1-2 phase excitation, W1-2 phase excitation, 2W1-2 phase excitation or the 4W1-2 phase excitation can be selected using the excitation switching signal (FMOT-Mode1/FMOT-Mode2). The edge switching signal (FMOT-Mode3) is used to specify the switching timing for excitation phase either from when both the rise and decay edge of the CLK input are detected or when only the rising edge is detected. Motor current value can be set discretionary by changing the level of the reference setting signal (FMOT-REF).

A drive clock signal (RMOT-CLK) and rotation direction signal (RMOT-CW/CCW) are input to control the speed and direction of the motor rotation. When the level of the enabling signal (RMOT-Enable) is set to "L", motor current is turned to OFF regardless of the state of other signals. For the excitation mode, either of 2 phase excitation, 1-2 phase excitation, W1-2 phase excitation, 2W1-2 phase excitation or the 4W1-2 phase excitation can be selected using the excitation switching signal (RMOT-Mode1/RMOT-Mode2). The edge switching signal (RMOT-Mode3) is used to specify the switching timing for excitation phase either from when both the rise and decay edge of the CLK input are detected or when only the rising edge is detected. Motor current value can be set discretionary by changing the level of the reference setting signal (RMOT-REF). © 2005 - 2011 TOSHIBA TEC CORPORATION All rights reserved MR-3018/3020/3021/3022 DESCRIPTION OF OPERATIONS 3 - 17 3.4.3 Drive Circuit for Exit Motor Fig. 3-8 This circuit controls the rotation/stoppage and the direction of rotation, excitation mode and motor current of the exit motor. A drive clock signal (EMOT-CLK) and rotation direction signal (EMOT-CW/CCW) are input to control the speed and direction of the motor rotation. When the level of the enabling signal (EMOT-Enable) is set to "L", motor current is turned OFF regardless of the state of other signals. As IC3-10pin (MODE1) is connected to +5V, excitation mode is applied at 1-2 phase excitation. The edge switching signal (EMOT-Mode3) is used to specify the switching timing for excitation phase either from when both the rise and decay edge of the CLK input are detected or when only the rising edge is detected. Motor current value can be set discretionary by switching the level of the reference switching signal (EMOT-REFS0,EMOT-REFS1). 3.4.4 Drive Circuit for FAN Motor Fig. 3-9 This circuit controls the rotation/stoppage of the fan motor. The FAN starts to rotate when the FAN motor drive signal level is set to “H”, and stops when the level is set to “L”. MR-3018/3020/3021/3022 DESCRIPTION OF OPERATIONS © 2005 - 2011 TOSHIBA TEC CORPORATION All rights reserved 3 - 18 3.4.5 Reset Circuit Fig. 3-10 This circuit generates a reset signal when the power is turned ON and the power voltage is blocked or cut off/lowered temporarily. At the power-ON, the circuit shifts the level of the reset signal from “L” to “H” to put the CPU in a operative state after the reset pulse duration (Tpd) determined by the capacitance of C58 has passed from when the power voltage has reached the supervisory voltage (Vs) divided by R116 and R117. When a power voltage drop (cutoff, temporary cutoff, temporary low voltage) occurs and the power voltage becomes lower than the set value for the supervisory voltage for the power, the circuit sets the level of the reset signal (RESET) to “L” to put the CPU in a halt state. 3.4.6 Drive Circuit for Pickup Solenoid Fig. 3-11 Pick up solenoid is a two-way solenoid that can be operated both in suction and recovery, and driven by two transistors (Q4 and Q2) for each operation respectively. When the PSOL-ON-Signal level is set to “L”, Q4 is turned ON, the power of 24V is applied to the coil for suction operation, the solenoid is turned ON, and then the pickup roller goes down. When the PSOL-ON-Signal level is set to “L”, Q2 is turned ON, the power of 24V is applied to the coil for recovery operation, the solenoid is turned OFF, and then the pickup roller goes up. © 2005 - 2011 TOSHIBA TEC CORPORATION All rights reserved MR-3018/3020/3021/3022 DESCRIPTION OF OPERATIONS 3 - 19 3 3.4.7 Drive Circuit for Gate Solenoid Fig. 3-12 Gate solenoid driven by the driver transistor (Q1) is a solenoid which is used to switch an original into the reverse tray when in the duplex scanning mode. When the GSOL-ON-Signal level is set to “L”, the reverse flap goes down and the original is transported to the reverse tray.
