AFR-20 Ver.1.0 Sep. 2003 |
A. Original feed operation
The paper feed system is driven by the paper feed motor (M301). The registration clutch (MC301) functions as the brake to stop the registration roller, not to turn ON or OFF the drive force transmission.
When M301 turns ON, the paper feed roller is pressed against the original set to the original feed tray. the original stopper goes up to the turnout position, and the paper feed roller and feed roller send the original to the registration roller.
The original is struck against the reversing registration roller and M301 stops after the specified time. Thus, a loop is formed before the registration roller to correct the skewed original.
After M301 stops, MC301 turns OFF to release the registration roller.
Then, M301 starts reversing operation, and the timing sensor (PS302) turns ON and stops after the specified time.
After that, M301 and conveyance motor (M302) start reversing at the same time to send the original to the conveyance belt (conveyance section).
After PS302 turns ON by the original sent as described above, M301 stops after the specified time.

B. Scanning and conveying the original
The transportation system is driven by the conveyance motor (M302).
The original fed to the conveyance belt (conveyance section) is positioned for scanning. Refer to "C. Original swing-back control" below for details of this process.
After the original is positioned, the scanner on the main body side scans the original.
Upon completion of scanning, M302 and reverse/paper feed motor (M303) turn ON and feed the original to the reverse/paper exit section.
M302 stops when the specified time elapses after the reverse sensor (PS305) turns ON.

C. Original swing-back control
Original is positioned for scanning by this function.
Original is conveyed beyond the original positioning plate, conveyance motor (M302) is stopped when the specified time elapses after the timing sensor (PS302) turns OFF, the motor starts reversing to return the original, and the original is struck against the original positioning plate and stops.
Striking control differs between thin paper and others (paper of normal thickness and thick paper), therefore thin paper mode is available to be used for setting the original.

D. Original reverse/paper exit operation
The reverse/paper exit system is driven by the reverse/paper exit motor (M303). Conveyance path is switched by the paper exit solenoid (SD301) and reverse solenoid (SD302), both of which are OFF in this mode.
Original from the conveyance section is wound around the reverse roller and sent to the reverse stocker. When the reverse sensor (PS305) turns OFF, M303 starts decelerating and stops. Then M303 starts reversing to send the original to the reverse/paper exit conveyance path. After the paper exit sensor (PS306) turns ON, M303 decelerates after the specified time and reverses to exit the original to the original stocker at a low speed.
After PS306 turns OFF, M303 stops after the specified time.

A. Original feeding operation
Refer to "A. Original feeding operation" of "1.2.1 Single sided original mode" as the original feeding operation is the same.
B. Original surface scanning and conveyance operation
Refer to "B. Original scanning and conveyance operation" of "1.2.1 Single sided original mode" as the surface scanning and conveyance operation are the same.
C. Original reverse/conveyance operation
The reverse system is driven by the reverse/paper exit motor (M303).
The conveyance path is switched by the paper exit solenoid (SD301) and reverse solenoid (SD302). At this time, SD301 turns OFF and SD302 turns ON.
Original from conveyance section is wounded around the reverse roller, guided by the reverse guide which is ON, and returned to the conveyance section getting under the conveyance roller.
After the reverse sensor (PS305) turns ON, both the conveyance motor (M302) and M303 stop after the specified time.
At the same time, M302 starts reversing, turns M303 ON, and returns the reversed original to the conveyance section to be scanned.
M303 stops at the specified time after PS305 turns OFF.

D. Reverse operation and scanning of original back side
The drive system is driven by the conveyance motor (M302).
The original returned to the conveyance section (conveyance belt) for scanning of the back side is sent in the reverse way when M302 starts reversing, stopped once, driven at a low speed again, and strikes the origin against the original positioning plate and stops.
After the positioning of original, the scanner on the main body side scans the original.
Striking control differs between thin paper and others (paper of normal thickness and thick paper), therefore thin paper mode is available to be used for setting the original.

E. Original exit operation
The paper exit system is driven by the reverse/paper exit motor (M303). Paper exit conveyance path is switched by the paper exit solenoid (SD301) which is ON here.
When the scanning is completed, the conveyance motor (M302) and M303 turn ON at the same time to send the original to the reverse/paper exit section. M302 turns ON and stops after the specified time. The original from the conveyance section is sent from the reverse roller to paper exit conveyance path guided by the paper exit guide at ON condition. When the reverse sensor (PS305) turns OFF, M303 decelerates after the specified time and exits the original to the original stocker at a low speed.
M303 stops when the specified time elapses after the paper exit sensor (PS307) turns OFF.

A. Normal copy mode
Main scanning direction is detected by the resistance value of the size VR (VR301) interlocked with the guide plate position on the paper feed tray. Sub-scanning direction is detected by the combination of the original size sensor/S (PS309) and original size sensor/L (PS310) when they are turned on and off.
B. Mixed original copy mode
Maximum original size in the main scanning direction is detected by the resistance value of the size VR (VR301) interlocked with the guide plate position on the paper feed tray.
Sub-scanning direction is detected by the time when the original passes by the timing sensor (PS302). Allowed size combinations are as shown in the table below.
