It is divided into the following chapters: General information contains a general description of the printer and the maintenance approach used to repair it. Special tools and test equipment, as well as general environmental and safety instructions, are discussed.

  • Page 21: General Information

    The optional finisher staples, punches, folding and stapling, and stacks media transferred from the Lexmark™ X850e, X852e, and X854e. Output is stacked in the upper media bin or separately collated in the stacker media bin or folded and stapled in the booklet bin.

  • Page 22: Media Path Overview

    7500-XXX Media path overview Media size and weight The following shows media sizes and weights that the finisher can handle, as well as applicable functions for each media size. The printer and the finisher handle different media sizes and weights. For this reason, if the printer has printed media that the finisher cannot handle, the exit 1 diverter gate in the printer is switched to eject the media from Exit 2 onto the bridge unit assembly.

    7500-XXX From bridge unit assembly to punch The media fed from the bridge unit assembly is fed into the finisher by the media entrance roll assembly located on the entrance section of the finisher which is driven by the drive motor (entrance/paddle). The media route inside the finisher is determined by the finisher diverter gate.

  • Page 29: From Punch To Compiler Unit Assembly

    7500-XXX From punch to compiler unit assembly The media is transferred to the compiler unit assembly by the buffer roll assembly (driven by the motor (buffer/ transport)) and by the lower media exit roll assembly (driven by the drive motor (exit)). When the first media reaches the compiler unit assembly, the media eject clamp motor is activated to lower the media eject clamp so that the media eject clamp and the media eject shaft assembly can clamp the media.

  • Page 31: From Compiler Unit Assembly To Stacker Media Bin

    7500-XXX From compiler unit assembly to stacker media bin Stapled media on the compiler unit assembly (stapling mode) or aligned media (non-stapling mode) are held between the media eject clamp and the media eject shaft assembly. The media eject shaft assembly is driven by the media eject motor assembly to transfer media to the stacker media bin.

  • Page 32: Finisher

    7500-XXX Finisher • Sensor (finisher media entrance) — A photo-reflective sensor detects whether media is fed from the bridge unit assembly to the finisher — It turns high (+5 V dc) while media is present within the sensing area. — When the level turns high due to the first media of the second set during multi-set printing, this sensor activates the buffer diverter solenoid to switch the buffer diverter gate so that the media goes in the buffer roll assembly’s circumferential direction.

  • Page 33: Punch Unit

    7500-XXX Punch unit This section describes the media punching operation of the punch. Two types of punch are provided: the 2/3-hole type and the 2/4-hole type. The following explains the 2/3-hole type (2-hole/3-hole auto-switching). Every type has the same construction, except for the sensor (punch hole select) that is provided for the 2-hole type and 3-hole type only.

  • Page 34: Punching

    7500-XXX Punching After punching positions are determined, the punch unit motor is activated to move the cam plate. With the movement of the cam plate, the pins descend along the guide holes to punch the media. This operation is performed for each sheet of media. The cam plate can lower the pins even while it is moving to the front or rear side.

  • Page 35: Detecting Punch Waste Full

    7500-XXX Detecting punch waste full Punch waste is stored in the punch waste box. A sensor is provided to detect punch waste full. When punch waste full is detected, it is notified to the operator only once. Even if punch waste is not removed, the finisher can still punch media. However, it can spread punch waste inside the machine.

  • Page 36: Compiler Unit Assembly

    7500-XXX • Sensor (punch waste box set) — A photo-interrupter sensor that detects whether the waste box is properly set — When the punch waste box is properly set, the actuator of the box blocks the light transmission of the sensor, which turns the sensor to high (+5 V dc).

  • Page 37: Capacity Of Compiler Unit Assembly

    7500-XXX Capacity of compiler unit assembly Media volume that can be stacked on the compiler unit assembly is limited as shown in the table below. The number of sheets depends on whether media is stapled or not, as well as on media size. If the number of sheets of one set to be stapled exceeds the limit, the exceeding sheets are not stacked on the compiler unit assembly, and are forcibly ejected to the stacker media bin without being stapled.

  • Page 38: Front Tamping

    7500-XXX Front tamping Front tamping is used in the following cases. • In the non-staple mode • When executing front stapling (corner) The tamper positions during front tamping are shown below. Sensor (rear tamper HP) Sensor (front tamper HP) Rear Front Front tamper motor Rear tamper...

  • Page 43: Media Sizes That Allow Stapling

    7500-XXX • Rear Staple (Straight) [rear straight] Rear This type of stapling is applied for media with a width of less than 216 mm. The Stapler staples a set of media in parallel with the media edge after the front tamper aligns the media to the rear side.

  • Page 44: Stapling Multiple Size Media

    7500-XXX Stapling multiple size media When sheets with different sizes and the same width (example: A4L and A3S) are present on the compiler unit assembly, all the sheets are stapled and then ejected to the stacker media bin. When sheets with different widths are present on the compiler unit assembly, stapling is stopped when a different width is detected.

  • Page 45: Stapler Unit Assembly

    7500-XXX Stapler unit assembly The stapling operation is executed by closing the stapler unit assembly. The stapler unit assembly, containing the staple motor, the sensor (staple home), the sensor (self priming), and the sensor (low staple), is activated by the staple motor. Forward (clockwise) rotation of the motor drives the stapler to staple a set of sheets, and returns the stapling unit to the home position.

  • Page 46: Booklet Operation

    7500-XXX • Stapler unit motor (in the stapler unit assembly) — A DC motor to activate the stapler unit assembly for stapling — Clockwise rotation of this motor enables stapling, while counterclockwise rotation returns the stapler unit assembly.

If 15 sets of printouts are detected in the booklet media bin, it will be considered as Full Stack.

  • Page 50: Stacker Media Bin

    7500-XXX Stacker media bin The stacker media bin goes up and down to an appropriate position according to the volume of media fed from the compiler unit assembly so as to properly stack media to a full stack. Operation The stacker media bin moves to an appropriate position according to the volume of media fed from the compiler unit assembly.
  • Page 51 7500-XXX The stacker media bin lowers according to the volume of media it contains. If any obstacle under the tray hinders the tray from lowering, the stacker lower safety warning is detected, and the stacker media bin is stopped. Eject clamp motor Sensor (stacker bin level 1) Sensor (media eject clamp HP)

  • Page 52: Full Stack Detection

    7500-XXX Full stack detection A full stack is detected when media in the stacker media bin becomes full to prevent media jam or falling of media to the floor. The stacker media bin can stack up to approximately 3000 sheets. The media volume in the stacker media bin is detected at every 10% (approximately 300 sheets) and notified to the Controller.
  • Page 53 7500-XXX — A photo-interrupter sensor that detects that the stacker media bin is at the highest position; it also detects no media. — When the actuator attached to the carriage assembly right enters the sensing area, the emitted light is blocked, which turns the sensor to high (+5 V).
