5 Introduction The following rules apply throughout this Service Manual: 1. Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and mechanical systems with reference to the timing of operation. In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol, the arrow indicates the direction of the electric signal. The expression "turn on the power" means flipping on the power switch, closing the front door, and closing the delivery unit door, which results in supplying the machine with power. 2. In the digital circuits, '1'is used to indicate that the voltage level of a given signal is "High", while '0' is used to indicate "Low".(The voltage value, however, differs from circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD signal goes on when '0'. In practically all cases, the internal mechanisms of a microprocessor cannot be checked in the field. Therefore, the operations of the microprocessors used in the machines are not discussed: they are explained in terms of from sensors to the input of the DC controller PCB and from the output of the DC controller PCB to the loads. The descriptions in this Service Manual are subject to change without notice for product improvement or other purposes, and major changes will be communicated in the form of Service Information bulletins.

F Basic Operation Outline The side paper deck (hereafter, "deck") is capable of accommodating as many as 3500 sheets of paper at a time (A4/LTR/B5; 80 g/m2), ready to pick up and feed paper in response to control signals from its host machine's DC controller. The lifter of the deck is driven by the deck lifter motor (M2), and the pickup operation is executed using the drive from the deck main motor (M1) Pickup Operation The paper placed in the deck is held up by the lifter at a specific point of paper pickup. When the Start key is pressed and the deck pickup clutch (CL2) goes on, the pickup roller starts to rotate by the drive of the deck main motor (M1), thus picking up paper. At this time, the pickup/feed roller and the separation roller make sure that no more that a single sheet of paper is moved ahead. Thereafter, when the deck pickup sensor (PS6) detects the paper, the deck pickup roller release solenoid (SL1) goes on so that the pickup roller leaves the surface of the stack of paper. The paper is then moved to the host machine's registration roller, where it is arched to remove any skew. The registration roller serves to control the paper so that its leading edge will match the image on the photosensitive drum. 2-3

When paper runs out and the paper detecting lever of the pickup roller assembly leaves the deck paper sensor, the host machine indicates the absence of paper on its control panel. 2-4

23 Chapter 2 Paper detecting lever Deck paper sensor Copy paper F-2-6 Paper detecting lever Lifter Deck paper sensor F-2-7 Lifter Changing the Deck Paper Size Changing the Deck Paper Size To change the paper size of the deck, you must move the guide plate in the deck to suit the user' s needs and then select the correct paper size in service mode: OPTION>ACC>DK-P Detecting the Level of Paper 3. Detecting the Level of Paper in the Deck The deck uses the deck paper supply position sensor (PS7), deck paper level sensor (PS8), and deck paper sensor (PS2) to check the level of paper inside its compartment; the result of the check is indicated on the host machine' s control panel. The following table shows how a check is made with reference to the states of the sensors: T-2-1 Paper level PS2 PS7 PS8 100% to about 50% about 50% to about 1 10% 1 0 less than 10% no paper : the light-blocking plate is over the sensor. 0: the light-blocking plate is not over the sensor. 2.4 Deck Lifter Detecting the Presence/Absence of Paper The lifter of the deck is joined to a reel by means of a cable, and is driven by the deck lifter motor (M2); i.e., the lifter moves up or down depending on the direction of rotation of the motor. When the deck (compartment) is pushed inside the host machine, the deck open detecting switch (SW1) is pushed. The lifter starts to move up as soon as the deck open sensor (PS9) detects the light-blocking plate; the lifter stops to move up when the deck position sensor (PS4) detects the top of the stack of paper placed on the lifter In the rare event that the lifter should fail to stop moving up after the sensor lever blocks the deck lifter position sensor for some reason, the deck lifter upper limit sensor (PS3) will go on to stop the lifter, thereby preventing damage to the deck. The lifter, on the other hand, starts to move down when the deck open switch (SW100) is pushed, and will keep moving down until the lifter moves past the sensor lever of the deck paper supply position sensor (PS7), i.e., falling edge of the sensor output. 2-5

24 Chapter 2 The addition of paper in this condition will push the lever of the deck paper supply position sensor, causing the lifter to move farther down until the stack of paper moves past the sensor lever. The lifter repeats its descent operation each time paper is added until the deck lifter lower limit detecting switch (SW2) is pushed (maximum paper supply position).

At the same time, the deck lifter motor (M2) starts to rotate to move down the lifter inside the deck. When the deck (compartment) is pushed into the host machine, the deck open sensor (PS9) detects the light-blocking plate, permitting the lifter to move up as far as the pickup position. When the deck lifter motor rotates to open/close the deck, the deck open indicator (LED100) on the open switch PCB goes on or flashes.

F Detecting Jams Outline The side paper deck is equipped with the following 2 sensors used to find out whether or not paper is moving smoothly. The machine checks for the presence of a jam at such times as initiated its DC controller PCB and with reference to the signals from these sensors. When the machine's DC controller PCB identifies a jam, it discharges sheets ahead of the jam and stops the ongoing operation, after which it will indicate jam removal instructions on its control panel.
