Page 33 2. Technical Explanation (Device) Primary charging roller Primary charging bias Photosensitive drum Step 3: Laser beam exposure In this step, a static latent image is formed on the Photosensitive Drum by the laser beam. When the negatively charged Photosensitive Drum is scanned by the laser beam, the negative charge is neutralized and this area turns into a static latent image.
Page 34 2. Technical Explanation (Device) ■ Transfer Block This block consists of 3 steps, and transfers the toner image on the Photosensitive Drum surface to the paper. Step 5: Primary transfer In this step, toner on the Photosensitive Drum is transferred to the ITB. A transfer bias is applied to the Transfer Roller, and the paper is positively charged.
Page 35 2. Technical Explanation (Device) Paper Static Charge Eliminator Secondary Transfer Roller ■ Fixing Block In this block, the toner image is fixed on the paper. Step 8: Fixing In this step, the toner image on the paper is fixed on the paper by on-demand fixing. The toner is fused onto the paper to form a permanent image by applying pressure and heat.

Page 39: Itb Unit
2. Technical Explanation (Device) For engagement/disengagement of the Developing Assembly, the Developing Assembly is engaged with or disengaged from the Photosensitive Drum by the DC Controller rotating the Developing Disengagement Motor to change the orientation of the Engagement/Disengagement Cam. The DC Controller controls the state of the Developing Assembly (engaged or disengaged) by the amount of rotation of the Development Disengagement Motor after detecting the output of the Developing Home Position Sensor.

The cassette detection flag of the cassette is detected by the Cassette Detection Switch in the host machine.
Page 49 2. Technical Explanation (Device) ● During Double Feed Since the friction force between sheets of paper becomes weaker when there are multiple sheets of paper, the Cassette Pickup Roller drive force transmitted to the Cassette Separation Roller becomes extremely weak. Since force suppressing rotation is applied to the Cassette Separation Rollers of this machine, this mechanism does not allow rotation by the weak drive force transmitted from the Cassette Pickup Roller during double feed.
Page 50 2. Technical Explanation (Device) Skew is corrected as follows. 1. The paper leading edge pushes against the Registration Shutter to align the leading edge of the paper. 2. The trailing edge of the paper is fed and slack is generated at the leading edge of the paper. 3.

Page 52: Jam Detection
2. Technical Explanation (Device) ■ Media Detection This machine automatically selects the optimal print mode for the media using the Media Sensor when the media is fed. The Media Sensor consists of a LED Sensor that detects the surface nature and an Ultrasound Sensor that detects the paper weight. The DC Controller detects the type of paper and switches the print mode based on the results detected by the Media Sensor.
Page 53: Pickup Delay Jam
2. Technical Explanation (Device) SR10 SR13 SR14 SR21 SR21 SR21 Occurrence of a jam is judged by whether paper is in the sensor area at the timings stored in the DC Controller. When the DC Controller judges that a jam has occurred, the printing operation is stopped and the jam is notified to the Main Controller at the same time.

Page 233: Obtaining Debug Log
7. Troubleshooting Obtaining Debug Log Function Overview Debug logs (hereinafter "Sublogs") are logs that record the internal operations of the Main Controller, and are used to analyze program operations and used by developers to identify problems. When a problem that is difficult to reproduce occurs, collecting a Sublog immediately after the problem has occurred on site can increase the efficiency of analyzing the problem and reduce the time it takes to deal with the problem.
Page 234: Sublog Collection Procedure
7. Troubleshooting Sublog Collection Procedure 1. Push SW1 on the board and confirm that LED1 turns on. If LED1 does not turn on, You need change the battery on Sublog board is located at BATS1 (CR2032) . CAUTION: There is danger of explosion if the battery is replaced with an incorrect type. Replace it only with the same type of battery.
