Page 28: Hcf Media Feed Unit Assembly Operation
7500-XXX HCF media feed unit assembly operation Upon receiving the feed start signal from the controller, the HCF activates the pick solenoid after a preset time has passed to press the pick roll against the media in the tray. After a preset time has passed, after receiving the feed start signal, the HCF feed lift motor rotates forward to feed media from the tray to the feed roll side with the pick roll.
Page 29: Hcf Media Transport Roll Assembly Operation
7500-XXX HCF media transport roll assembly operation Upon receiving the feed start signal from the controller the HCF activates the HCF transport motor at a high speed after a preset time has passed. This rotating power of the HCF transport motor is transmitted to the HCF media transport roll assembly, and the media from the HCF media feed unit assembly is transferred to the printer.
Page 30: Hcf Media Feed Unit Assembly Sensor/Motor Functions
7500-XXX HCF media feed unit assembly sensor/motor functions Functions of the sensors and motors of the media feed unit assembly are outlined below. • HCF media feed lift motor–is a stepping motor that rotates (forward) the pick roll and feed roll to send media from the tray to the HCF media transport roll assembly.
Page 31: Status Monitoring
7500-XXX Status monitoring This function includes detection of static media jams, interlocking, and insertion of the HCF media tray assembly. Static media jam detection This function checks the status of all relevant sensors on the media path to detect media jams. When media is present on the sensor, it is treated as a static jam.
Page 32: Tray Insertion Detection
7500-XXX Tray insertion detection The sensor (HCF media tray set) checks whether the tray is properly set. This check is constant while the power is on. Printing operation is inhibited if the sensor (HCF media tray set) off (tray is not present) is detected before printing starts.
Page 33: Media Size Detection
7500-XXX Media size detection When media is loaded in the tray, the media size is automatically detected by the rear media edge guide that is attached to the media tray assembly and aligned with the side of the media. The position of the rear media edge guide is detected by the sensor (HCF media size L) and the sensor (HCF media size R).
Page 34: Tray Lifting
7500-XXX Tray lifting Tray lift operation starts automatically when the HCF media tray is inserted with media loaded. Media is lifted and stops at the feeding position. At the same time, detection of no media and remaining media volume becomes available. HCF feed lift motor Feed lift gear bracket asm Bottom plate...
Page 35: Sensor (Media Out)
7500-XXX If the HCF media tray is not lifted, the media out actuator remains in the sensing area of the sensor (media out), while blocking the light transmission of the sensor (media out). Media out is detected regardless of the presence of media in the tray.
Page 36: Sensor (Media Level)
7500-XXX • If the sensor (media level) is off when the power is turned on, the HCF regards the HCF media tray as having been removed, and determines the remaining media volume based on the time from the media feed lift motor forward/reverse rotation until the sensor (media level) comes on.

The media eject shaft assembly is driven by the media eject motor assembly to transfer media to the stacker media bin.
Page 47: 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 48: 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 49: 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 50: 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 51: 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 52: 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 58: 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 59: 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 60: 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 62: 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 63 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, 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 64: 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 65 7500-XXX • Sensor (stacker bin no media) — 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).
