1. Electrostatic latent image formation stage This stage follows two steps to produce an electrostatic latent image on the photosensitive drum. At the end of the stage, negative charges remain on the unexposed “dark” areas, where the laser beam struck (exposed) the drum sur face. This image of negative charges on the drum is invisible to the ey[...]

Step 2 Scanning exposure Figure 2-4-7 When the laser beam scans the drum sur face, it causes the charge to be neutralized in the areas struck by the laser beam. These areas on the drum sur face for m the electrostatic latent image. 2. Development stage Particles of toner are placed onto the electrostatic latent image on the sur face of the drum to [...]

As shown in Figure 2-4-8, the developing unit consists of a developing cylinder and a rubber blade. The developing cylinder rotates around a fixed inter nal magnet. The single-component toner consists of magnetite and a resin binder , and is held to the cylin- der by magnetic attraction. The toner is an insulator , and acquires a negative charge fr[...]

Reference: If the image on the photosensitive drum is not completely transferred onto the paper due to jam- ming, etc., the toner may adhere to the transfer charging roller . The printer removes the toner from the transfer charging roller by switching the transfer voltage between positive and negative in the specified sequence. During wait mode, in[...]

4. Fixing stage The toner image transferred onto the paper in the transfer stage is held only by electrostatic attraction and a slight physical adhesion, so even a light touch will smear the image. In the fixing stage, the toner image is fixed by heating the paper and applying pressure. This fuses the toner particles onto the paper to create a per [...]

5. Drum cleaning stage In the transfer stage, not all the toner is transferred to the paper . Some remains on the photo- sensitive drum. This residual toner is cleaned of f in the drum cleaning stage so that the next print image will be clear and distinct. Step 8 Drum cleaning Figure 2-4-14 The residual toner on the drum sur face is scraped away wi[...]

b. Lift-up operation The lift-up operation is executed by the multi-input tray drive motor when a cassette is installed or the pick-up roller shaft is set lower than certain level due to the paper reduce. The two cases for the lift-up operation are as follows. Figure 2-5-7 2 - 49 CHAPTER 2 Pick-up roller F eed roller 1 Separation roller Pick-up rol[...]

1) Cassette is installed ➀ When a cassette is installed, the multi-input tray drive motor rotates, and the cassette paper pick-up solenoid (SL3) is tur ned ON. Then, the shaft drive ar m is driven by the cassette paper pick-up cam rotation through the gear . Figure 2-5-8 2 - 50 CHAPTER 2 Main motor drive Lifter gear Lift-up cam Pick-up roller shf[...]

➁ As the shaft drive ar m goes down, the pick-up roller shaft goes down. Then, the lift-up release ar m is pushed, and the lift-up cam is unfixed. At the same time, the shaft drive ar m is fixed to the pick-up roller shaft fixing ar m, and the pick-up roller shaft is stopped in the designated position. Figure 2-5-9 ➂ The lift up cam starts rota[...]

➃ The pick-up roller shaft is lifted up when the paper on the paper lifting plate touches the pick-up roller . Then, the fixing ar m is released, and the lift-up release ar m lifts up the pick- up roller shaft to the waiting position by force of the spring. At the same time, the lift-up cam is fixed by driving the pick-up roller shaft fixing ar m[...]

2) Paper level is lower than certain level ➀ As the paper level lowers, the moving distance of the pick-up roller increases. When the moving distance reaches the specified value, the pick-up roller shaft pushes the lift up release ar m, and the lift up cam is unfixed. Figure 2-5-12 2 - 53 CHAPTER 2 Lift-up arm Pick-up roller shaft fixing arm Pick[...]

➁ When the lift-up cam is unfixed, the lift-up ar m lifts up the lifter gear one tooth by the rota- tion of the lift-up cam. The paper lifting plate is lifted up by repeating the operation. (See Figure 2-5-10) ➂ When the paper on the paper lifting plate touches the pick-up roller , the pick-up roller shaft is lifted up. Then, the fixing ar m is[...]

c. Multi-feed prevention mechanism When feeding from the cassette, the printer uses the separation roller to prevent multi-feeding. Nor mally, the separation roller is imparted with a rotational force opposite to that of the feed roller . However , since the separation roller is equipped with a tor que limiter , it rotates with feed roller 1 by tra[...]

2. Manual feed (multi-purpose tray) The presence of paper on the multi-purpose tray is detected by the multi-purpose tray paper sensor (PS1301). When the DC controller receives the /PRNT signal from the video contr oller , the lifting plate solenoid (SL2) tur ns ON, the lifting plate is unlocked (the lifting plate rises), and the paper touches the [...]

C. Fixing and Delivery Unit The upper and lower rollers of the fixing unit, and the face-up and face-down delivery rollers are driven by the main motor (MT1). The paper separated from the photosensitive drum is fed into the fixing unit, and sent from the fixing unit by the fixing roller and fixing unit delivery roller . The paper sent from the fixi[...]

The printer switches between face-up and face-down tray delivery with the face-up deflector . When the FACE-UP SOLENOID DRIVE signal (/FUSLD) becomes “L”, the face-up solenoid (SL3) moves the face-up deflector to the face-up tray and the paper is delivered through the face-up tray. If /FUSLD is “H”, the paper is delivered through the face-d[...]

D. Paper Jam Detection The following paper sensors are provided to detect whether paper is present and whether the paper is fed nor mally. • Registration paper sensor (PS1) • Pick-up unit paper sensor (PS2) • Fixing unit delivery sensor (PS1403) • Face-down tray delivery sensor (PS1402) The microprocessor (CPU) deter mines whether paper is [...]

7. Residual paper jam a. The CPU assesses a residual paper jam if the fixing unit delivery sensor (PS1403) detects the paper after the power -ON. b. The CPU assesses a residual paper jam if it does not receive an automatic delivery command within 3 minutes after notifying the video controller of the presence of paper which can be automatically deli[...]
