  • Page 53: Duplex Unit (Option)

    5016-001 Duplex Unit (Option) One side print The print fed by the paper feed rollers in tray 1 in the printer and in the second paper feed unit is halted temporarily at the timing roller for registration. The paper then passes through the transfer unit, in which the image is formed, and is fused in the fuser assembly.
  • Page 54 5016-001 Two sided print When the printer has been set for two sided print mode and start is pressed the following occurs: When the setting is two pages. The paper feed roller in the printer starts rotating. The paper is transported by the timing roller and the back page is printed.
  • Page 55 5016-001 When the trailing edge of the paper passes through the reverse sensor filler (S4], the motor rotates in the reverse direction transporting the paper in reverse. The print is transported to the timing roller in the printer through the rollers in the curved area, the skew correction mechanism and the paper feed roller.
  • Page 56 5016-001 When the setting is four pages The back page of the first printed page is printed after Print Start is pressed. The print is received in the upper unit through the above step and then halted when it reaches the paper exit sensor [S5] through the storage, reverse and skew correction mechanisms in the lower unit.
  • Page 57 5016-001 When the setting is not less than six pages or three prints This operation stages pages in the lower and upper units and alternates transportation as shown in the preceding steps. These steps are performed successively. 1-33 General Information...
  • Page 58 5016-001 Exit of the one sided print When the printed page passes through the paper exit sensor in the printer, the upper duplex unit motor rotates in the reverse direction, rotating the gate claw in reverse, so that paper is ejected to the paper exit tray.
  • Page 59 5016-001 Detecting the paper exit tray open/close When the paper exit tray opens to remove a jammed print, the sensor lever shuts off the open/closed sensor so that detection is performed. Detecting the duplex upper unit open/close When the upper unit opens, the actuator detaches from the right sensor pin in the right hinge.
  • Page 60 5016-001 Gate claw operation, when print exits When the leading edge of a duplexed page prints, it turns the paper exit sensor in the printer on. The duplex upper unit motor starts rotating in the reverse direction, rotating the claw gear. The gate claw rotates counterclockwise feeding the page to the paper exit roller.
  • Page 61 5016-001 Storage of the paper in the duplex unit The page that is transported from the duplex rear unit pushes on the gate claw and is stored in the duplex lower tray unit. When the trailing edge of the page passes through gate claw 2, gate claw 2 is rotated by the gate claw spring until the gate claw lever touches the stopper, switching to reverse paper exit mode.
  • Page 62 5016-001 Operation of the motor When the leading edge of the paper reaches the paper pass sensor in the duplex upper unit, the upper unit motor goes into high speed mode (270m/sec). At this time, the duplex lower unit motor rotates in the normal direction.
  • Page 63 5016-001 When the page is transported from the duplex rear unit for storage, the reverse sensor detects the paper. After the sensor detects the paper, for a specified time, the motor turns off and the print is stored. The duplex lower unit reverse motor supplies drive to the duplex rear unit and tray through gear 18Z.
  • Page 64 5016-001 When paper is fed from the 2nd paper option, the chassis side input gear rotates in [B] direction. The drive is transmitted to the one way gear 16Z through the store roller drive shaft, rotating the one way gear 16Z in the [B] direction. Note: Drive is not transmitted when the rotation is in the [A] direction, due to the one way clutch [A].
  • Page 65 5016-001 Skew Correction The holder mounted on the lower side of the rear cover is inclined about 3 degrees, in the paper pass direction. The page is brought to the opposite side of the skew correction mechanism in the duplex lower tray unit by this inclination for the preparation of skew correction.
