PagePro 1200 Series Mechanical / Electrical 4. 4-1. Mechanical/Electrical Paper Path Paper can be fed into the printer either from the Multi-purpose Tray (PagePro 1200W: 150 sheets; PagePro 1250E 200 sheets) or Manual Feed Tray. The paper feed system can be extended to a 3-way system by Installing the Second Paper Cassette Unit (500 sheets). The paper fed by the Paper Take-up Roller is transported to the Image Transfer Roller, Fusing Roller and then Paper Exit Roller.
PagePro 1200 Series Mechanical / Electrical 4-2. (1) Paper Take-up Section Multi-purpose Tray Mechanism • When the Paper Take-up Solenoid is energized, the drive of the Main Motor is transmitted to the Paper Take-up Roller via the Paper Take-up Gear (one-way clutch) to turn the Paper Take-up Roller one revolution. • At the same time, the Depressing Cam turns and lifts the Paper Lifting Plate, and the first (top) sheet of paper on the tray is fed to the printer.
PagePro 1200 Series Mechanical / Electrical Paper Empty Detection There is a Paper Empty Sensor provided on the upper side of the Multi-purpose Tray. It functions to detect a paper-empty condition in the Multi-purpose Tray and the Manual Feed Tray. When there is paper, the actuator is raised and thus the sensor light is blocked. When paper runs out, the actuator drops into a cutout in the tray, thus unblocking the sensor light.
PagePro 1200 Series Mechanical / Electrical Cassette Type Detection The Second Paper Cassette Unit is provided with a Cassette Type Detecting Switch that comes with a lever. When the paper cassette is slid into position, the projections on the right-hand side of the cassette push the lever according to the size of the paper loaded in the cassette, thus turning off or on the Cassette Type Detecting Switch. The Cassette Type Detecting Switch consists of three subswitches.
PagePro 1200 Series Mechanical / Electrical 4-3. (1) Drum Charge Overview • The PC Drum is charged with static electricity before laser exposure. • The Drum Charge Brush and the Pre-charge Film are used for the charging method. • The Drum Charge Brush and Pre-charge Film charging generate little ozone in the printer. Because the charge is directly applied to the PC Drum, the PC Drum can be charged by low voltage. At the same time, the PC Drum can be charged stably and evenly.
PagePro 1200 Series Mechanical / Electrical 4-4. Laser Exposure Laser exposure is the process of creating an invisible static charge image on the PC Drum by the laser beam emitted from the Print Head Unit. This process is controlled as follows in order to appropriately time image printing.
PagePro 1200 Series Mechanical / Electrical /VIDEO /HSYNC /VIDEO 4 mm Print Area 4 mm 51 /TOD PRINTING AREA • The controller sends the VIDEO signal at the appropriate paper size to the engine (Controller Board). • The controller determines the start point of printing according to the TOD signal (sub-scanning direction) sent from the engine (Controller Board) and the HSYNC signal. • Laser exposure is started when the print head receives the VIDEO signal.

PagePro 1200 Series Mechanical / Electrical (2) Explanation of Each Part No. Name Description 1 Toner Hopper Contains toner. 2 Toner Agitating Screw Agitates the toner in the Toner Hopper and sends the toner to the Toner Transport Roller. 3 Toner Transport Roller Transports the toner to the Sleeve Roller. 4 Sleeve Roller Turns the Resin Sleeve. 5 Resin Sleeve Carries the toner to the PC Drum surface for development.
PagePro 1200 Series Mechanical / Electrical 4-6. (1) Image Transfer Overview • Image transfer is the process of transferring the toner image created on the PC Drum in the developing process to paper. • Roller image transfer is used instead of corona image transfer as the image transfer method. • In roller image transfer, there is little generation of ozone due to corona discharge. Also, there is no blur of toner because the paper is always pressed by the PC Drum and the Image Transfer Roller.
PagePro 1200 Series Mechanical / Electrical (1) Overview • The toner image transferred onto the paper is securely fixed to the paper. • A heat roller system is used as the fusing system. The toner image is fused by the Heat Roller heated by the Heater Lamp, and securely fixed by the pressure between the Heat Roller and Backup Roller.
PagePro 1200 Series Mechanical / Electrical At 600 dpi The printer is initialized upon power supply. The printer then starts warming up and the Heater Lamp turns on. The temperature is controlled as follows. Mode 1 The temperature is controlled to maintain 125°C (PagePro 1250E) or 115°C (PagePro 1200W) dur- ing standby and 200°C during printing. If this mode continues for 300 seconds (PagePro 1250E) or 90 seconds (PagePro 1200W), the control will shift to mode 2.

(1) Paper Exit Face-up/Face-down Selection Mechanism After fusing, the paper is ejected onto the Face-down Tray or the Face-up Tray by the Face-up/Facedown Selection Mechanism. An optional Face-up Tray can also be selected. Switching the paper exit to use the Face-up Tray is done with the Face-up/Face-down Selection Switch.
PagePro 1200 Series Maintenance / Disassembly 5. 5-1. (1) Precautions for Maintenance/Disassembly Precautions for Disassembly Observe the following precautions whenever servicing the printer. • Be sure to unplug the printer from the outlet before attempting to service the printer. • To reassemble the printer, reverse the order of disassembly unless otherwise specified. • Generally, do not operate the printer anytime during disassembly.
PagePro 1200 Series Maintenance / Disassembly (3) Instructions for Handling the PWBs with MOS ICs The following precautions must be observed when handling circuit boards with MOS (Metal Oxide Semiconductor) ICs. • During transportation or when in storage, new circuit boards must not be indiscriminately removed from their protective conductive bags. • Do not store or place circuit boards in a location exposed to direct sunlight.

PagePro 1200 Series Troubleshooting 7. 7-1. (1) Troubleshooting Paper Misfeed Detection Overview The printer determines if paper is left inside itself by detecting the status (H or L) of the signal output from the Paper Take-up Sensor (PS1) and the Paper Exit Sensor (PS3). A paper misfeed while paper is being transported is detected by monitoring the timing at which the signal from the Paper Take-up Sensor (PS1) or the Paper Exit Sensor (PS3) rises or falls.
