      1. THE AIM OF ANTI-TIP COMPONENTS AND PRECAUTIONS

         The anti-tip components 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 in weight, from toppling as a result of people running into or leaning onto 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.

      2. MECHANISM

Paper feed separation mechanism

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

Drive mechanism

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

Separation roller/pick-up roller release mechanism

When the right tray is set, the friction roller comes in contact with the feed roller. The pick-up roller touches the top sheet of paper that is to be transported.

When the right tray is opened, contact between the feed roller and friction roller, and contact between the pick-up roller and paper are released.

Paper feed transport mechanism

In order to feed the paper at regular intervals, there is a paper feed sensor between the pick-up roller and the feed roller, and this sensor is used to adjust the paper feed timing.

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

2. To prevent the next sheet from being transported, the pick-up solenoid turns ON just before the trailing edge of the first sheet passes through the pick-up roller, and the pick-up roller leaves the paper surface.

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

   However, at this time, if the paper feed sensor does not detect paper (the second sheet is not transported to the paper feed sensor position), the paper feed motor does not turn OFF.

   Pre-feed is performed as follows:

   1. The pick-up solenoid turns OFF, and the second sheet of paper is transported to the paper feed sensor position.

   2. When the trailing edge of the second sheet passes the feed roller, the paper feed motor is turned OFF. The pick-up solenoid remains OFF.

4. Just before the trailing edge of the first sheet passes the feed roller, the pick-up solenoid turns OFF. The pick-up roller is brought into contact with the paper surface.

5. When the first sheet has been transported a specified distance by the downstream transport roller, the paper feed motor turns ON to feed the second sheet.

PAPER FEED UNIT PB3150 (D694)

Tray bottom plate lift

When the paper feed tray is set in the main frame, the tray set sensor switch turns ON. The coupling of the lift motor connects with the shaft at the rear of the tray, and the motor rotates to lift the tray bottom plate. The tray bottom plate rises until the paper surface lifts up the pick-up roller and the upper limit sensor turns OFF (the sensor is blocked). The tray is now ready to feed.

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

Paper size detection

The end fence is linked mechanically with the size detection actuator. When the end fence is moved, the size detection actuator also moves.

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

PAPER FEED UNIT PB3150 (D694)

Paper size detection switch operation

Remaining paper/paper end detection

Remaining paper detection

Remaining paper in the paper feed tray is detected by a combination of ON/OFF status (contact/non-contact) of contact-type remaining paper sensors (boards) CN-3 and CN-5. When the amount of remaining paper decreases, and the 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.

Paper end detection

When there is no more paper in the paper feed tray, the paper end feeler turns ON the paper end sensor (the sensor is unblocked).
