[. . . ] This manual covers all localities where the products are sold. For this reason, there may be information in this manual that does not apply to your locality. Corrections This manual may contain technical inaccuracies or typographical errors due to improvements or changes in products. When changes occur in applicable products or in the contents of this manual, Canon will release technical information as the need arises. [. . . ] The changes of the developing DC bias value makes the potential difference between the cylinder and drum so that the density of the print can be adjusted. Transfer Stage In the transfer stage, the toner image is transferred from the drum surface onto the paper. Step 4: Transfer Photosensitive drum Paper Transfer charging roller Figure 2-4-10 Positive charges are applied to the back of the paper to attract the negatively charged toner particles to the paper. Step 5: Separation Photosensitive drum Paper e Static charg eliminator Transfer charging roller Figure 2-4-11 The elasticity of the paper causes it to separate from the drum (curvature separation). To stabilize the paper feed system and to prevent droplets on the printed image at low temperature and low humidity, the charge on the back of the paper is reduced by the static charge eliminator. 2 - 28 CHAPTER 2 4. Fixing Stage As the toner image transferred onto the paper in the transfer stage is held to the paper only by the static electricity, even a light touch will smear the image. The toner particles are fused to the paper to make a permanent image by applying pressure and heat to the paper and toner. Step 6: Fixing Fixing film Toner Fixing film Fixing heater Toner Paper Pressure roller Paper Pressure roller Figure 2-4-12 As the toner particles transferred onto the paper are held to the paper by the positive charge applied to the back of the paper, they may be dispersed at fixing. This printer applies the negative DC voltage to the fixing film via the pressure roller shaft. The negative charge is applied to the paper surface by the fixing film before the paper reaches the fixing heater. This improves the adhesion force of the toner particles to the paper and prevents dispersion of the toner particles. These photointerrupters detect paper's reach and pass. If the paper does not reach or pass the sensors within the specified period of time, the CPU on the engine controller determines a paper jam and notifies it to the interface controller. In this printer, print paper is loaded from the top of the printer. To prevent this, the printer contains a pickup retry function. If the paper top sensor does detect the leading edge of paper within the specified period of time after the pickup solenoid turns ON, instead of determining a jam, the printer tries to pickup the paper again. The printer performs the pickup retry up to twice. If the paper top sensor cannot detect the leading edge of the paper within the specified period of time in the third trial, the printer determines that a paper pickup delay jam has occurred. Note: Initial rotation ready The state in which the main motor is rotating, the fixing unit temperature has reached its specified value in a specified period of time after the start of main motor rotation, and the scanner motor has reached its specified rotation speed. 2 - 32 CHAPTER 2 B. Jam Detection The following paper sensors are installed to detect whether paper is present and whether the paper is fed correctly: · Paper top sensor (PS002) · Paper delivery sensor (PS201) The CPU determines a paper jam by checking for the presence of paper in the sensor at the timing stored in the CPU. If the CPU determines that a jam has occurred, it stops the print operation and notifies the jam to the interface controller. Pickup delay jam When the paper does not reach the paper top sensor (PS002) after the pickup solenoid (SL001) has been turned ON three times within the specified period of time (includes two pickup retry operations. ) 2.
