  • Page 44 CHAPTER 2 2. First page The stapler stacker driver stops the delivery motor (M2) when the trailing edge of the first page passes the delivery roller 1 by 20mm. 0.2 seconds later, M2 is rotated counterclockwise, which shifts the M2 gear to the swing guide gear side. As a result, M2 rotates the swing guide gear and the swing guide is lifted (open).

  • Page 56 CHAPTER 2 III. POWER SUPPLIES A. Outline The power supply unit of the stapler stacker uses a remote switch system. When the power switch of the printer is turned ON, the printer outputs the commands to the option controller PCB via the video controller PCB. According to these commands, the option controller PCB out- puts the POWER ON signal (PWRON-IN) to the power unit via the stapler stacker driver PCB, and turns ON the power.

Outline When a paper jam or failure occurred in the stacker, the condition of the stacker can be checked with the Service LED on the staple stacker driver PCB (LED1: Red light). The Service mode can be changed according to the combination of the DIP switches (SW2) on the same PCB.

    CHAPTER 4 V. MALFUNCTION TROUBLESHOOTING If the factor of malfunction was identified as "malfunction troubleshooting" by the malfunction diagnosis flowchart (Figure 4-1-1), perform the following actions. V-1. No power <Possible causes> 1. POWER-ON signal is not input due to poor contact in option interface connector. Action: Reconnect the option interface connector correctly.

If it is not 0 Ω with the swing guide down and ∞ Ω with the guide up, replace the swing guide close detection switch (MS2). 3. Swing guide close detection switch (MS6) failure Action: Disconnect the connector J5 on the staple stacker driver PCB.
  • Page 109 CHAPTER 4 4. Stapler transfer motor failure Action: Disconnect the connector J8 on the staple stacker driver PCB. Measure the resis- tance between the connector J8-5 and J8-4, -3, -2, or -1 on the motor side. If it is not about 16.5 Ω, replace the stapler transfer motor. 5.
  • Page 110 CHAPTER 4 Action: Reconnect the connector J7 on the staple stacker driver PCB. 3. Tray up/down motor failure Action: Disconnect the connector J7 on the staple stacker driver PCB. Measure the resis- tance between the connector J7-4 and J7-5 on the motor side. If it is not about 6.5 Ω, replace the tray up/down motor.
  • Page 111 CHAPTER 4 VI-13. Printer cannot become READY because "staple jam status" is output when the sta- ples are not jammed. <Possible causes> 1. Poor contact in connectors. Action: Reconnect the connector J308 on the stapler, J8 on the intermediate PCB 1, J303 on the intermediate PCB 2 and J8 on the staple stacker driver PCB correctly.

    CHAPTER 4 VII. MEASUREMENT AND ADJUSTMENT A. Mechanical Adjustment • No mechanical adjustment required. B. Electrical Adjustment 1. Adjusting the distance sensor This adjustment is required if the staple stacker driver PCB or the distance sensor is replaced or if the back-up power supply failure is indicated with the LED (see Page 4-7). As the distance sensor is adjusted at the factory, its adjustment at the time of installation is not necessary.

    CHAPTER 4 VIII. MAINTENANCE AND SERVICING A. Periodic Replacement Parts • No parts require periodic replacement in this stacker. Note: Periodic replacement parts are the parts that must be replaced at regular intervals, even if they are functioning properly and show no signs of wear. (Failure of these parts can seriously affect the performance.) These parts should be replaced during a regular service visit closest to the end of the parts expected life.
