3 Explanation of Symbols The following symbols are used throughout this Service Manual. Symbols Explanation Symbols Explanation Check. Remove the claw. Check visually. Insert the claw. 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. Check the noise. Disconnect the connector. Connect the connector. Remove the cable/wire from the cable guide or wire saddle. Set the cable/wire to the cable guide or wire saddle. Use the bundled part. Push the part. Plug the power cable. Turn on the power.. 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. All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service Information bulletins and be able to identify and isolate faults in the machine. Remove the screw. Tighten the screw.

7 Notes Before it Works Serving Points to Note at Cleaning 0-7 CAUTION: At servicing, be sure to turn off the power source according to the specified steps and disconnect the power plug. CAUTION: When performing cleaning using organic solvent such as alcohol, be sure to check that the component of solvent is vaporized completely before assembling. CAUTION: Do not turn off the power switch (of the host machine) when downloading is under way. Turning off the main power switch while downloading is under way can disable the machine. 0-7

12 Technology > Controls > Pre-registration Stop Control -3 Controls Overview Paper inside a cassette is lifted up by the Lifting Plate. When pickup takes place, the Cassette Pickup Solenoid (SL101) is turned ON so that the Pickup Roller is moved down. When the Pickup Roller comes in contact with the surface of paper, the paper is picked up by rotation of the roller. Only a single paper picked up is moved to the feed path by the Feed Roller and the Separation Roller, and moved as far as the Registration Roller by the Pickup Vertical Path Roller. If the Pickup Sensor is ON when starting pickup (in the case that the succeeding paper is also picked up when a paper is picked up and fed), the feed speed is decreased. The Pickup Vertical Path Roller, Pickup Roller, Feed Roller, and Separation Roller are driven by the Cassette Pickup Motor (M101). Pre-registration Stop Control To ensure throughput when picking up from the Cassette 3/, preceding pickup is executed so that the second sheet of paper and later are moved to the pre-registration stop position.

If the Cassette Retry Sensor (PS103) is not turned ON after re-pickup operation, a delay jam is notified. Technology > Controls > Pre-registration Stop Control -3

13 Technology > Controls > Paper Size Detection Control Paper Size Detection Control Rear Guide Plate - Paper size in a cassette is automatically detected by the "Cassette Size Switch". Paper size in a cassette is automatically detected by adjusting the Guide Plate position. By shifting the Guide Plate, concavo-convex area of the Cassette Size Dial is switched and the Cassette Size Switch at the printer side is switched. The switch consists of microswitches, and length and width are detected in accordance with the combination of ON/OFF. As long as standard size paper, it can be used for both AB configuration and inch configuration. However, distinction between A5-R and STMT-R and between EXEC-R and 16K-R should be specified manually on the check screen.
