        1. PRECAUTIONS CONCERNING STABILIZERS

           The stabilizers are necessary for meeting the requirements of IEC60950-1, the international standard for safety.

           The aim of these components is to prevent the products, which are heavy, from toppling as a result of people running into or leaning on the products, which can lead to serious accidents such as persons becoming trapped under the product. (U.S.: UL60950-1, Europe: EN60950-1) Therefore, removal of such components must always be with the consent of the customer.

           Do not remove them at your own judgment.

     PAPER FEED UNIT PB3210/PB3220 (D787)

  2. MECHANISM

  
  

  Paper Feed Separation Mechanism

  Paper feed is an RF paper feed system. The paper feed unit comprises a pick-up roller, feed roller and friction roller. These rollers are high durability.

  In the RF system, paper separation is assisted by the resistance of a separation roller with a torque limiter (reverse drive is not performed).

  
  

  Drive Mechanism

  The pick-up roller and feed roller are driven by the paper feed motor [A]. The transport roller is driven by the transport motor [B]. The friction roller is not driven.

  

  
  

  Friction Roller/Pick-up Roller Release Mechanism

  When the paper feed tray is set, the friction roller comes in contact with the feed roller, and the pick-up roller contacts the uppermost sheet of paper.

  However, when the paper feed tray is pulled out, to prevent paper from dropping out, the contact between the feed roller and friction roller, and between pick-up roller and paper is released.

  
  

  Paper Feed Transport Mechanism

  In this MFP, to maintain a fixed clearance between sheets, a paper feed sensor is provided near the pickup roller, which adjusts the paper feed timing.

  

  1. The paper feed motor turns ON, and supplies the first sheet.

  2. To prevent the next sheet from being fed, the pick-up solenoid switches ON just before the trailing edge of the first sheet leaves the pickup roller, and the pickup roller separates from the paper surface.

  3. Slightly before the trailing edge of the first sheet leaves the paper feed roller, the paper feed motor switches OFF.

     However, at this time, when the paper feed sensor detects no sheet (when the second sheet is not fed to the paper feed sensor position), pre-feed is performed without switching the paper feed motor OFF.

     Pre-feed is as follows.

     1. The pickup solenoid switches OFF, and the second sheet of paper is fed to the paper feed sensor position.

     2. When the trailing edge of the second sheet passes the feed roller, the paper feed motor is switched OFF. The pickup solenoid remains OFF.

  4. Just when the trailing edge of the first sheet passes the paper feed roller, the pickup solenoid is switched OFF, and the pickup roller is brought in contact with the paper surface.

  5. When the first sheet is fed a predetermined distance by the downstream transport roller, the paper feed motor is switched ON to supply the second sheet.

  PAPER FEED UNIT PB3210/PB3220 (D787)

  Tray Base Plate Lift

  When the paper feed tray is set in the main unit, the set switch switches ON, and it is detected that the tray is set. At this time, the coupling of the lift motor engages with the shaft at the rear of the tray, the motor rotates, and the tray base plate is lifted up. The paper surface pushes up the Pickup roller, the tray base plate is lifted until the upper limit sensor switches OFF (blocked), and the machine enters the standby mode.

  When the paper feed tray is removed, the coupling is disengaged, and the base plate descends. At this time, the lift motor rotates until the coupling returns to the home position.

  Paper size detection

  The end fence interlocks mechanically with the size detection actuator, and when the end fence is moved, the size detection actuator also moves.

  When the paper feed tray is set, 4 size detection switches switch ON/OFF depending on the position of the size detection actuator. Paper size is detected by the detected combination of these switches.

  PAPER FEED UNIT PB3210/PB3220 (D787)

  Remaining paper detection/paper end detection

  Remaining paper detection

  Detection of paper remaining in the paper feed tray is performed by a combination of ON/OFF (contact/non-contact) of contact-type remaining detection plates (printed circuits) CN-3, CN-5. When the amount of remaining paper decreases, and the tray lift motor rotates, the remaining paper sensors CN-3 and CN-5 in the motor are turned ON/OFF.

  The following 4 levels of remaining paper can be detected:

  
  

  Amount remaining	100%	70%	30%	10%
  CN-3	OFF	ON	ON	OFF
  CN-5	OFF	OFF	ON	ON
  Control panel remaining paper display	4 bars	3 bars	2 bars	1 bar

  
  

  Paper end detection

  When the paper feed tray is empty, the paper end sensor switches ON (unblocked) due to the end feeler.

        1. OPERATION PANEL UNIT

           
           

           • Turn off the main power switch of the MFP and disconnect the power cord.

           • After replacing, make sure that all disconnected harnesses are connected up again and secured in their clamps (if the MFP has harnesses).

             

           • When handling the operation panel cable, hold down the connector of the cable with your finger as shown in the picture to prevent excessive force from being applied to the connector of the PCB.

             

             
             

           • If excessive force is applied to the connector of the PCB in the direction of the arrow, connection failure may occur.

             

           • For machines manufactured in October 2016 or later, a bracket [A] will be added to cover the connector of the cable.

             

             1. Remove the operation panel unit from the MFP.

                
                

                • For details about how to remove the operation panel unit, refer to the service manual for the MFP.

                • By factory default, switches No.3 and No.7 of the DIP switch [A] on the micro computer board are set to ON. When installing the operation panel unit, make sure that the DIP switch setting is correct for the MFP on which you are installing the panel.

                  

                • The correct DIP switch setting depends on the MFP. Note the DIP switch settings of the old operation panel unit before replacing, and apply the same settings to the new Smart Operation Panel. (Below are two examples for DIP switch settings.)

             
             

             When No.3 and No.7 are set to ON	When only No.3 is set to ON

             • This is the factory default setting of a service part

             
             

• If the DIP switch setting is wrong, SC672 will be displayed.

• After replacing the operation panel unit, make sure that the latest version of the firmware is installed on the Smart Operation Panel. Update it if necessary (page 62 "Updating the Smart Operation Panel").
