Power Distribution System The AC and DC power supply circuits are contained in the Low Voltage Power Supply (LVPS). The high voltages required for image formation ar e generated by the High Voltage Power Supply (HVPS). The Low Voltage Power Supply and Distribution System is illustrated in Figure 5-2. Refer to the Reference Diagrams at the end of Ch[...]

AC Power Distribution The AC power circuitry supplies AC voltage whenever the power cord is connected, and the power switch is ON. A toner cartridge must be installed and the top access door must be closed before AC voltage is supplied to the DC power circuits or the Fusing Assembly. Overcurrent/Overvoltage Protection There are two overcurr ent/ove[...]

High V oltage Power Distribution The High Voltage Power Supply (HVPS, see Figure 5-4) applies a DC biased AC voltage to the primary charging roller and the developing roller, and a programmed DC voltage (depending upon the phase of the printing proc ess) to the Transfer Roller. Refer to the General Timing Diagram (Figur e 5-22) at the end of this c[...]

Formatter System The Formatter PCA is responsible for the following: • Controlling the PowerSave mode. • Receiving and processing pr int data from the various printer inter faces. • Monitoring Control Panel inputs and relaying printer status information (through the Control Panel and the Bi-Directional I/O). • Developing and coordinating da[...]

Note Printer error messages over ride the PowerSave message. The printer will enter PowerSave mode at the appropriate time, but the error message will continue to be displayed. Resolution Enhancement (REt) The Formatter PCA contains circuitry for Resolution Enhancem ent technology (REt), which modifies the standard video dot data on its way to the [...]

DC Controller System The following systems and functions are controlled by the DC Controller PCA: • DC Power Distribution (+5V DC, +12V DC, +24V DC) • Laser and Scanner Drive • Paper Motion Monitoring and Control (photosens ors and flags) • Clutches (registration, tray pickup, and Tray 1 feed) • Engine Test • Motors (Main Drive, Scanner[...]

Engine T est Microswitch The Engine Test Microswitch, located on the DC Controller PCA, is activated manually through the square access hole at the right rear of the printer (see Figure 6-4). This switch causes the pr int engine to perform an internal self test diagnostic which bypasses the Formatter PCA and then prints a full page of black paralle[...]

Image Formation System Laser printing requires the interaction of several different technologies (such as electronics, optics, and electrophotographics) to provide a printed page. Each process functions independently and must be coordinated with the other printer processes. The image formation process consists of six steps: 1 Drum Cleaning 2 Drum C[...]

T oner Cartridge The toner cartridge is the “heart” of the Image Formation System. It houses the cleaning, conditioning, and developing steps of the process. The toner cartridge contains the photosensitive drum, pr imary charging roller, developing station, toner cavity, and cleaning station. Including the components that wear, degrade, or are [...]

Drum Cleaning The cleaning blade inside the toner cartridge is in contact with the surface of the drum at all times. As the drum rotates during printing, excess toner is removed from the drum surface and stor ed in the waste toner receptacle inside the toner cartridge. Drum Cleaning Figure 5-8 5-14 Functional Overview[...]

Drum Conditioning After the drum is physically cleaned, it is conditioned by applying a uniform negative charge across the surface of the drum with the pr imary charging roller, located in the toner cartridge. The primary char ging roller is coated with conductive rubber, charged with an AC curr ent which erases any residual charges, and produc es [...]

Image W riting During the writing process, a modulated laser diode projects a beam onto a rotating six-sided scanning mirror. As the scanning mir ror rotates, the beam is directed through a set of focusing lens es to a direction changing mirror which reflects it through a slot on the top of the toner cartr idge, and onto the photosensitive drum. Th[...]

Image Developing The developing process changes the latent electrostatic image into a visible image by depositing negatively charged toner particles on the exposed ar eas of the drum. The developing station is located inside the toner cartridge and consists of a metallic cylinder that rotates around a fixed magnetic core. The developing cylinder is[...]

Image T ransferring and Media Separation During the image transferring process, the toner image on the drum surface is transferred to the media. A positive char ge applied to the back of the media by the transfer roller, causes the negatively char ged toner particles on the drum surface to be attracted to the media. The small diameter of the drum, [...]

Image Fusing The Fusing Assembly bonds the toner particles into the media with a heated fusing roller and a soft pressure roller. Ther e are two levers on the Fusing Assembly which adjust roller pressure for single sheets (down position), or envelopes (up position). Both levers must be set to the same position. The fusing roller contains two quartz[...]

Printer Input Sources Paper Size Switches The paper guides in Trays 2 and 3 operate four levers at the back of the trays which activate the size sensing switches (SW1601 through SW1604) mounted in the printer chassis. Table 5-8 compares paper sizes to switch conditions. Printing from T rays 2 and 3 The Pickup, Feed, and Separation rollers start rot[...]

Printing from T ray 1 The presence of paper in Tray 1 is detected by the Tray 1 Paper Present Sensor (PS1301). The lifting plate pressurization solenoid (SL2) is then activated, releasing the plate which applies upward pressure on the paper, causing it to contact the Tray 1 pickup roller. The Tray 1 Feed Clutch (CL3) turns on at this time and feeds[...]

Paper Jam Detection The PIU Sensor (PS2), the Registration Sensor (PS1), the Fuser Delivery Sensor (PS1403), and the Face-Down Delivery Sens or (PS1402) detect when paper is moving through the printer (see Figure 5-15 for sens or locations). If a paper jam is detected, the DC Controller immediately stops the printing process and causes a 13.x PAPER[...]
