    PAPER FEED 6.8.3 PAPER FEED/SEPARATION PRESSURE ADJUSTMENT MECHANISM Paper feed pressure C262D071.WMF The feed pressure motor [A] rotates, pulling or releasing the spring [B] through the rack [C]. The lever [D] moves up or down depending on the tension of the spring. If the spring is pulled, the lever moves upwards, reducing the paper feed pressure.

  • Page 401: Paper Separation Pressure

    PAPER FEED Paper separation pressure The paper separation pressure, the paper feed pressure and the friction pad that is used for separation depends on the paper type selected at the operation panel. When the paper type is changed, the three motors automatically turn to change the pressure settings and friction pad block.

  • Page 402: Friction Pad Exchange Mechanism

    PAPER FEED Friction Pad Exchange Mechanism C262D073.WMF The friction pad ([A] or [B]) that is used depends on the paper type setting, and the settings of SP 6-011. To use the normal pad [A], the friction pad shift motor [C] drives the rack [D]. When friction pad position sensors 1 [E] and 2 [F] are both actuated, the friction pad shift motor stops.

  • Page 403: Paper Types

    PAPER FEED Paper Types The user can select the paper type before starting the job. The feed and separation pressures used for the job will depend on the selected paper type (the machine automatically adjusts these pressures to suit the selected paper type). The possible paper type settings are standard, thick, thin and special.

  • Page 405: Paper Registration Mechanism

    PAPER FEED 6.8.4 PAPER REGISTRATION MECHANISM Registration Roller Drive C262D075.WMF The lower registration roller [A] is driven by the registration motor [B] (stepper motor). When the paper comes into contact with the rollers, the motor remains stopped to create a buckle in the paper to obtain precise paper registration and to prevent paper skew.
  • Page 406 PAPER FEED NOTE: 1) The registration motor rotation speed is constant. However, when the operator selects a higher or lower printing speed (to change the copy image density), the drum and pressure cylinder rotation speed changes. The registration motor must feed the paper at the correct time for the leading edge to be caught by the paper clamper on the pressure cylinder.

  • Page 407: Registration Roller Up/Down Mechanism

    PAPER FEED Registration Roller Up/Down Mechanism C262D076.WMF After the paper is caught by the paper clamper and is between the drum and the pressure cylinder, the upper registration roller is released from the lower registration roller. This is to prevent interference from the registration rollers while the paper is being fed by the drum and the pressure cylinder.

  • Page 408: Paper Feed Control Mechanism

    PAPER FEED 6.8.5 PAPER FEED CONTROL MECHANISM Registration Roller C262D077.WMF The paper feed timing around the registration roller [A] is monitored by two different photo-sensors. The first is the paper registration sensor [C], which is located before the registration roller. The second sensor is the paper feed timing sensor [B], which is located after the registration roller.

  • Page 409: Paper Feed Retry Mechanism

    PAPER FEED 6.8.6 PAPER FEED RETRY MECHANISM When paper is misfed at the paper feed tray, a paper feed jam is not displayed, and the machine tries to feed the paper again. The paper registration sensor does not turn on after the paper feed motor turns, and the pressure cylinder turns without paper.

  • Page 410: Registration Roller Pressure Release Mechanism

    PAPER FEED 6.8.7 REGISTRATION ROLLER PRESSURE RELEASE MECHANISM C262D079.WMF When a jam occurs at the paper registration roller [A], the pressure of the registration roller will be released so that the jammed paper can be removed easily. The registration press motor [B] turns and pushes down the pin [C]. This releases the pressure of the registration roller.

  • Page 411: Double Feed Detection

    PAPER FEED 6.8.8 DOUBLE FEED DETECTION Mechanism C262D080.WMF The double feed sensor [A] at the registration roller [B] detects differences in the quantity of light through the paper. The sensor measures this at about 13 mm from the leading edge of the paper. If the quantity of light becomes less, the machine detects a double feed.

  • Page 412: Recovery From Double Feed

    PAPER FEED Recovery from Double Feed When two sheets of paper feed through together at the registration sensor, and if the two sheets of paper get to the double feed sensor, the machine detects a double feed and stops paper feed. However, if the two sheets of paper are separated before they get to the double feed sensor and the second sheet does not get to the registration sensor, the machine will not detect a paper jam.

  • Page 413: Paper Table Angle Adjustment Mechanism

    PAPER FEED 6.8.9 PAPER TABLE ANGLE ADJUSTMENT MECHANISM C262D081.WMF There are two paper table open positions: level, and 15 degrees upward slant. Normally the paper table is set at the level position. The 15 degrees upward slant position is used to feed special types of paper, such as envelopes, which are difficult to feed at the level position.

    PRINTING AND PRESSURE CYLINDER 6.9 PRINTING AND PRESSURE CYLINDER 6.9.1 OVERVIEW C262D096.WMF This model uses a pressure cylinder, instead of a press roller. Two printing pressure springs [A] (one each at front and rear) pull the pressure cylinder up against the drum through the front and rear printing pressure arms [C]. (The arms rotate around the shaft [D].) Normally, the arms are engaged and the printing pressure is not applied.

  • Page 423: Pressure Cylinder

    PRINTING AND PRESSURE CYLINDER 6.9.2 PRESSURE CYLINDER C262D097.WMF To stabilize the image density and print registration, and to decrease noise during printing, the pressure cylinder [A] has the same diameter as the drum (diameter 180 mm and 300 mm in circumference). The paper clamper [B] is on the outer surface of the pressure cylinder, and the encoder plate [C] for monitoring the speed of rotation is on the rear of the pressure cylinder.

  • Page 424: Paper Clamping

    PRINTING AND PRESSURE CYLINDER 6.9.3 PAPER CLAMPING C262D098.WMF The paper clamper catches the leading edge of the paper after it has passed the registration roller. Normally, the paper clamper is held open by spring [A]. At the same time as the leading edge of the paper enters the clamper, the high point of the cam [B] reaches the bearing [C] on the lever at the front end of the paper clamper, and the clamper closes.

  • Page 425: Printing Pressure Mechanism

    PRINTING AND PRESSURE CYLINDER 6.9.4 PRINTING PRESSURE MECHANISM Rear Front C262D099.WMF There are two printing pressure springs [D] and two printing pressure arms [B], one each at front and rear. The pressure cylinder rests on the printing pressure arms. Normally, the arms are engaged and the printing pressure is not applied.

    PAPER DELIVERY 6.10 PAPER DELIVERY 6.10.1 OVERVIEW C262D109.WMF The paper delivery unit consists of three rubber belts [A] and the vacuum fan motor [D]. The rubber belts are driven by the main motor, and they feed the paper, which is held against the belts by suction generated by the vacuum fan motor. The paper pick-off plate [E] is located close to the pressure cylinder, in order to prevent the paper from being wrapped around the pressure cylinder or entering under the delivery unit.

  • Page 435: Paper Separation From The Drum

    PAPER DELIVERY 6.10.2 PAPER SEPARATION FROM THE DRUM Exit Pawl Drive Mechanism Rear Front C262D110.WMF The exit pawl [B] guides the center of the paper. This prevents the paper from wrapping around the drum. As the drum rotates and the master clamper approaches the exit pawl, the exit pawl moves away from the drum.

  • Page 436: Air Knife Mechanism

    PAPER DELIVERY Air Knife Mechanism C262D111.WMF There are three air knife fans [A] above the paper delivery unit. These fans blow air against the leading edge of the paper that is just fed from the drum. This helps to separate the paper from the drum. The air knife fans are more powerful than the ones in the previous models.

  • Page 437: Paper Pick-Off Plate Mechanism

    PAPER DELIVERY Paper pick-off plate mechanism C262D112.WMF The paper pick-off plate [A] can move. When the paper is firmly wrapped around the cylinder, the pick-off plate cannot remove it. In this case, the paper moves back the pick-off plate and lifts it away from the pressure cylinder. This prevents jams that are caused by the paper being stuck at the paper pick-off plate.

  • Page 438: Paper Delivery Wing Mechanism

    PAPER DELIVERY 6.10.3 PAPER DELIVERY WING MECHANISM C262D114.WMF The paper guide wings [A] lift the side of the paper as it leaves the delivery unit. This stiffens the paper so that the leading edge of the paper will not sag and brush against the sheets on the delivery table.

  • Page 439: Paper Delivery Table Mechanism

    PAPER DELIVERY 6.10.4 PAPER DELIVERY TABLE MECHANISM C262D127.WMF The paper delivery table consists of the rear side fence, front side fence, and end fence.
