Paper Loading(ASF) / Paper Feeding(PF) / Paper Ejection(EJ) Mechanism
Overview
This product has the paper transport path on the right side of the product. Since the paper jam can be cleared on the right side of the product, the installation space on the left side of the product can be minimized. In the standard model, cassettes C1/C2 and Paper trays are available for paper supply port, and the paper feed port can be expanded by installing the optional additional cassette (C3/C4) and High capacity unit. In the standard model, face-down tray is available for paper ejection port, and the paper eject port can be expanded by installing the optional Inner tray, Floor finisher and Inner finisher.
The following describes the details of the three mechanisms of Paper loading (ASF), Paper feeding (PF), and Paper Ejection (EJ).
Main Components (ASF)
This mechanism enables paper to be fed, and loads and feeds the paper to the paper feeding mechanism.
| A | Cassette Unit | Makes the paper set inside the cassette ready for loading. Paper size is automatically detected by aligning the edge guide with the size of the set paper. |
|---|---|---|
| B | Right Door Unit (Paper Tray) | The Paper tray can feed thick paper such as special paper (envelopes, postcards, etc.) that cannot be fed from the cassette. Two types of rollers and paper size detection sensors are installed inside the unit to prepare for paper feeding. |
| C | Pickup Unit | Three types of rollers (pickup/separating/retarding) inside the unit feed each sheet of paper in the cassette and transport it to the paper path. Also, the presence or absence of paper in the cassette is detected by a sensor. |
| D | PW Sensor Unit | Two sensors inside the unit detect the width of the paper being transported. If a paper size different from the setting is detected, paper feed is stopped. |
| E | Registration Unit | Corrects skew of the fed paper. The pre-printing sensor in the unit detects the edge of the paper and controls the ink ejection timing. |
Main Components (PF)
This structure is a mechanism for feeding paper during printing.
| A | Anti Static Brush Unit | Perform static elimination and paper dust removal before feeding the paper to the belt unit. It also has sensors related to print control (Pre-printing sensor/Pre-head paper sensor). |
|---|---|---|
| B | Belt Unit | The unit located below the nozzle surface of the head unit that transports paper during printing. |
Main Components (EJ)
This structure is a mechanism for ejecting paper during printing.
| A | D3 Unit | Paper path component that feeds printed paper to the paper ejection port. |
|---|---|---|
| B | Right Door Unit (Duplex path) | In addition to the paper feed function with the Paper tray, it also feed paper during duplex printing. |
| C | Stacker Unit | Stocks the paper ejected to the Face-down output tray. The trough shape suppresses paper curl and maintains paper alignment. |
Paper Feed Path
Paper path for single sided printing
Paper fed from the cassette or Paper tray is transported as follows.
Paper feed path when duplex printing
A sheet printed on single side is conveyed to a duplex path. The paper is switched back in the duplex path, and the printed surface is reversed. After that, the sheet is transported to the paper path again and duplex printing is performed.
