PagePro25 1 CONFIGURATION OF THE PRINTER The following diagram shows the major parts of the printer and the paper path in the printer. The printer consists of the paper feed section, print head unit (exposure section), imaging cartridge (charging section and development section), transfer section, fusing section, and paper exit section.
PAGE 30
PagePro25 1-1. General Description of Each Section (1) Paper Feed Section Paper is fed from either the tray 1 (1st paper cassette) or tray 2 (2nd paper cassette). When the printer receives a print command, the paper take-up solenoid turns ON and a sheet of paper is fed by the paper take-up roller in the 1st paper cassette. The synchronizing roller sensor (PC2) detects the fed paper and the paper is fed to the synchronizing roller for printing.
PAGE 31
PagePro25 1-2. General Flow for Printing Process The following shows the general printing process flow. Note: For detailed printing sequence, see 10 “Printing Sequence”. Print Command The polygon motor in the print head unit starts turning. Polygon motor ON Starting processing • Charge bias, developer bias, seal bias and transfer bias voltages are applied. • The I/C (Imaging Cartridge) drive motor (M1) starts turning. Paper take-up • The transport motor (M2) starts turning.
PAGE 32
PagePro25 2 PAPER FEED SECTION 2-1. Tray 1 (1st Paper Cassette) 2-1-1. Taking up Paper The power is transmitted from the transport motor (M2) as follows to take up paper from the 1st paper cassette. 1 The transport motor (M2) turns counterclockwise → 2 The idle gear turns clockwise. →The 1st cassette paper take-up solenoid (SL1) turns ON. → 3 The paper take-up roller turns counterclockwise. → Paper is taken up. Note: The rotational direction is the one viewing from the front of the printer.
PAGE 33
PagePro25 2-1-2. Sensors for Tray 1 (1) 1st Cassette Set Sensor (PC6) This sensor detects the installation of the 1st paper cassette in the tray 1. This sensor uses a photointerrupter. If the 1st paper cassette is not installed in the tray 1, the projection of the paper cassette comes off the sensor which is mounted on the printer. In this case, the light emitted from the LED of the photointerrupter reaches the phototransistor of the photointerrupter and the phototransistor turns ON.
PAGE 34
PagePro25 (3) 1st Cassette Paper Near Empty Sensor (PC5) This sensor detects the paper near empty status of the 1st cassette paper. The sensor uses a photointerrupter. As the sheets of paper in the paper cassette decrease, the paper lifting plate in the paper cassette lifts. When the paper lifting plate lifts exceeding a certain point, the 1st cassette paper near empty occurs. When enough paper is present in the paper cassette, the paper lifting plate is lowered.
PAGE 35
PagePro25 (5) Synchronizing Roller Sensor (PC2) This sensor detects that the paper is fed inside the printer. The sensor uses a photointerrupter. The output of the sensor is used as a reference for feeding paper inside the printer. This sensor will be activated when paper is fed from any paper source. Without paper, the sensor arm is pressed by a spring and the end of the sensor engages with the photointerrupter.
PAGE 36
PagePro25 2-2. Tray 2 (2nd Paper Cassette) 2-2-1. Taking up Paper The power is transmitted from the transport motor (M2) as follows to take up paper from the 2nd paper cassette. 1 The transport motor (M2) turns counterclockwise → 2 The idle gear turns clockwise. → 3 The 1st cassette paper takeup gear turns counterclockwise. → 4 The 1st cassette idle gear turns clockwise. The transport clutch (CL1) turns ON. → Power is transmitted to the 2nd paper cassette.
PAGE 37
PagePro25 2-2-2. Sensors for Tray 2 (1) 2nd Cassette Set Switch (SW3) This switch detects whether the 2nd paper cassette is installed in the tray 2 or not. This switch also detects the paper cassette type; 250 sheet universal cassette or 500 sheet fixed cassette. If no paper cassette is installed on the tray 2, the switch is not pressed by the paper cassette. When the 250 sheet universal cassette is installed, the left side of the switch is pressed by the projection of the cassette.
PAGE 38
PagePro25 2nd Cassette Paper Near Empty Sensor (PC25) Light is blocked: Output = H Light passes: Output = L Paper Few paper Paper Lifting Plate [Paper near empty] [Paper is present.] (4) 2nd Cassette Side Door Detecting Sensor (PC23) This sensor detects whether the 2nd cassette side door is closed or not. The sensor uses a photointerrupter. The side door is normally closed except when removing jammed paper.
PAGE 39
PagePro25 2-3. Paper Feed The paper taken up by the paper take-up section is fed to the transfer section after registration compensation. (1) Registration Compensation To eliminate any paper slant (skew), registration compensation is made by controlling the rotating timing of the paper take-up roller and synchronizing roller. The taken up paper passes the synchronizing roller sensor (PC2) and reaches the synchronizing roller.
PAGE 40
PagePro25 3 PRINT HEAD UNIT (EXPOSURE SECTION) The print head unit incorporates a laser diode that emits the laser beam corresponding to the print image data. The spot of the laser beam emitted from the laser diode is shaped in a circle through the collimator lens. Then, it is applied to the heptagonal polygon mirror via the cylindrical lens. The polygon mirror is turned by the polygon motor in the print head unit in the direction as shown by the arrow.
PAGE 41
PagePro25 4 MAGING CARTRIDGE 4-1. Parts Names and Functions of the Imaging Cartridge The following illustrates the construction of the imaging cartridge. The power to the gears of the imaging cartridge is transmitted from the I/C drive motor (M1) of the printer main body. (The I/C drive motor (M1) turns clockwise viewing from the front of the printer.
PAGE 42
PagePro25 4-2. Charging Section Before producing an electrostatic latent image on the surface of the PC drum with a laser beam, the PC drum is charged by static electricity with the rotating charge bush so that the surface of the PC drum is negatively charged. The charging system uses the rotating charge brush system. Since this charging system can apply charge directly to the PC drum, charging is possible at a low voltage, producing negligible amount of ozone.
PAGE 43
PagePro25 The seal beneath the sleeve roller acts to discharge the negatively-charged unused-toner on the sleeve roller. The discharged toner is fed back to the toner feed roller for recycling it. Note that, during printing, the seal voltage is the same a s the sleeve roller voltage and discharge is not made. However, before and after printing, the voltage of the seal bias is set 100V higher than that of the sleeve roller to discharge the unused toner for recycling.
PAGE 44
PagePro25 6 FUSING SECTION The power from the transport motor (M2) is transmitted to the upper fusing roller so that the toner-transferred paper is fed from the transfer section to the fusing section. The paper is heated to melt the toner by the upper fusing roller and pressed by the upper and lower fusing rollers. The upper fusing roller is heated by the fusing roller heater lamp (H1) which is built in it.
PAGE 45
PagePro25 Fusing temperature control: • When the power switch is turned ON, the printer starts warm-up until the upper fusing roller temperature reaches approx. 200°C. (It will take about one minute.) (Warming-up mode) • To maintain the upper fusing roller temperature above 190°C, the control circuit raises the temperature and keeps at approx. 210°C for approx. five minutes. (Mode 1) • The control circuit gradually decreases the temperature by 190°C in five minutes.
PAGE 46
PagePro25 7 PAPER EXIT SECTION The paper fed from the fusing section passes through the paper exit roller and ejected to the top of the printer with its printed side facing down. The transmit power for feeding paper is given by the transport motor (M2) and transmitted in the order from 1 ~ B shown in the figure.s The paper exit sensor (PC3) detects ejection of paper. This sensor uses a photointerrupter.
PAGE 47
PagePro25 8 DETECTION OF A NEW IMAGING CARTRIDGE The printer has the function to detect whether the newly installed imaging cartridge is a new one or used one. In the imaging cartridge, an internal circuit is incorporated as shown in the figure. A fuse is connected in parallel with a resistor and it is not blown. Accordingly, by measuring the voltage across the resistor, the printer can know whether the imaging cartridge is a new one or not.
