equipment is classified into the following mechanisms: n SCANNER MECHANISM - Document feeding and ejecting mechanism - Document scanning mechanism n LASER PRINTING MECHANISM - Paper pick-up and registration mechanism - Print process mechanism (consisting of charging, exposing, developing - Brother International 8350P | Service Manual - Page 32
of the document take-in roller ASSY, niprelated parts, separation roller ASSY, and ADF parts) feeds those documents into the equipment, starting from the bottom sheet to the top, page by page. Each document advances with the document feed roller ASSY to the scanner, and then it is fed out of the - Brother International 8350P | Service Manual - Page 33
for feeding paper to the transfer block in the drum unit. When the leading and trailing edges of the paper pass through the registration sensor actuator, the sensor signals them to the controller. According to those signals, the controller may determine the first print position on the paper. III - Brother International 8350P | Service Manual - Page 34
2.2.2 Print process mechanism The print process unit works with laser beam, electrical charges, and toner. The graph below shows the transition of electrical charge on the surface of the laser-sensitive drum through the four processes: charging, exposing, developing, and transferring processes. III - Brother International 8350P | Service Manual - Page 35
the frame. (2) Exposing process When the laser-sensitive drum holds a positive electrical charge, the laser beam issued from the laser unit scans the drum according to the print image to expose the drum surface for neutralizing the spots where black should be, forming an electrostatic latent image - Brother International 8350P | Service Manual - Page 36
. If paper jam or other errors occur, the toner image fails to stick to the paper and will stick to the transfer roller. To repulse this toner, the controller positively charges the transfer roller. The toner returns from the transfer roller to the drum. During non-printing rotation of the drum, the - Brother International 8350P | Service Manual - Page 37
passes between the heater roller and the pressure roller in the heat-fixing unit, the heater roller fuses the toner on the paper. The controller monitors the internal resistance of the heater thermistor to keep the surface temperature of the heater roller constant by turning the halogen heater - Brother International 8350P | Service Manual - Page 38
-fixing process, it will be ejected from the heat-fixing unit by the paper ejection roller. If the leading edge of the paper pushes up the actuator of the paper ejection sensor, the sensor signals the start of paper ejection. If the trailing edge has passed through the sensor actuator, the sensor - Brother International 8350P | Service Manual - Page 39
has reached the starting position and when the scan for that page is over. • Manual insertion sensor which detects whether paper is inserted manually through the paper slot or whether paper fed through the paper cassette has jammed. • Registration sensor which detects the leading and trailing edges - Brother International 8350P | Service Manual - Page 40
