Basic operation This chapter presents an overview of the relationships among major components in the device, and includes a detailed discussion of the image-formation system.

The following systems are discussed: Engine control unit ECU The ECU coordinates all device functions, according to commands that the formatter sends. The ECU contains the following components: Fuser heater control circuit Figure Low-voltage power supply circuit diagram ENWW Basic operation The ECU uses two motors and two solenoids to drive the rollers. Three media-detection sensors detect media as it passes through the device.

If media does not reach or pass each sensor within a specified time period, the ECU determines that a jam has occurred and alerts the formatter. Image-formation system Laser printing requires the interaction of several different technologies, including electronics, optics, and electrophotographics, to provide a printed page.

Figure Print cartridge diagram Each process functions independently and must be coordinated with the other device processes. Image formation consists of the following five processes: Primary charging DC and AC biases are applied to the primary charging roller, which transfers a uniform negative potential to the photosensitive drum. Figure Primary charging Step 2: Laser beam exposure The laser beam scans the photosensitive drum to neutralize negative charges on parts of the drum.

An electrostatic latent image is formed on the drum where negative charges were neutralized. Toner acquires a negative charge through friction from the developing cylinder and the blade. When the negatively charged toner comes in contact with the drum, the toner adheres to the electrostatic latent image. The image on the drum becomes visible because of the toner.

Transfer The transfer charging roller, to which a DC positive bias is applied, imparts a positive charge on the print media.

Figure Fusing Step 7: Drum cleaning The cleaning blade scrapes the residual toner off of the photosensitive drum and deposits it into the waste toner case. Figure Drum cleaning ENWW Basic operation Internal components Figure Cross-section of device on page 56 highlights the major internal components. Tray 1 separation pad Feed roller Tray 2 separation pad Tray 2 pickup roller Duplex pickup roller Feed roller, registration assembly Transfer roller Oblique roller Duplex feed roller Fuser pressure roller, fuser assembly Fuser delivery roller, fuser assembly ENWW Internal components Timing The microprocessor on the engine control unit ECU controls the device operation sequences.

Table Operation sequences on page 58 describes engine operations for each period of a print operation. Table Power-on sequence on page 58 describes each step of the power-on sequence. Table Operation sequences Name Print cartridge memory system The memory tag is a nonvolatile memory built into the print cartridge. The cartridge usage condition is detected as the engine controller reads or writes the data stored on the memory tag. The engine controller renews the information in the prescribed timing and reads or writes it from or to the memory tag.
