Laser/scanner system The formatter sends video signals to the DC controller, which controls the laser/scanner. When the laser/scanner system receives those signals it converts them to latent images on the photosensitive drum. Figure 4-4 Laser/scanner system 52 Chapter 4 Theory of operation ENWW[...]

Pickup-and-feed-system The pickup and feed system consists of several types of feed rollers and sensors. The DC controller drives the system by controlling the feed motor (M4), ETB motor (M5), and four drum motors (M6, M7, M8, M9) and the solenoids for the trays. In models that include an automatic duplex accessory, the duplexing feed motor (M10) a[...]

Sensors in the pickup-and-feed system trays (cassettes) Paper sensors detect media in the trays. Other sensors react to the media as it moves through the paper path. If the media does not reach or pass each sensor within a specified time period, the DC controller determines that a jam has occurred and alerts the formatter. In models that include an[...]

Multipurpose-tray pickup mechanism The cassette must be installed in order for the multipurpose (MP) tray to operate. The MP tray paper sensor (SR707) detects whether media is present in the MP tray. When the cassette is correctly installed and media is present, the MP tray pickup operation begins. 1. The DC controller receives a print command from[...]

The following jams can occur during operation: ● Pick-up delay jam. The printer makes three attempts to pick up media from a tray. When the top- of-page sensor (SR710) does not detect the leading edge of a page within a specific time after the third attempt, the printing operation stops. The time varies depending on the printer model and the medi[...]

HP CLJ 3000: approximately 2.0 seconds (in Normal print mode) HP CLJ 3600: for black printing in Normal mode, 1.4 seconds; for color printing, 2.5 seconds HP CLJ 3800: approximately 2.5 seconds (in Normal print mode) ● Residual-paper jam.[...]

Image-formation system The image-formation system, which forms a toner image on media, consists of several interdependent systems: ● Electrostatic latent-image-formation ● Developing ● Transfer ● Fuser ● Drum cleaning The printer includes four print cartridges that contain the toner than is used to create the image on the media. Toner is [...]

Image-formation process Laser printing requires the interaction of several different technologies including electronics, optics, and electrographics to provide a printed page. Each process functions independently and must be coordinated with the other processes. Image formation consists of the following five processes: 1. Latent-image formation 2. [...]

Figure 4-10 Image-formation steps Latent-image formation stage During the three steps that comprise this stage, a latent image is formed by applying a negative charge to the photosensitive drum. You cannot see this image on the drum. Step 1: pre-exposure The pre-exposure LED hits the photosensitive drum surface and eliminates any residual charge on[...]

Figure 4-11 Pre-exposure Step 2: primary charging A high-voltage dc bias is applied to the primary charging roller, which is made of conductive rubber and is in contact with the drum surface. As the roller moves across the drum, it applies the negative charge to that surface. Step 3: laser-beam exposure The laser beam scans the photosensitive drum [...]

Step 5: media feed The printer generates electrostatic force to pull a sheet of print media to the ETB. The sheet adheres to the belt and travels between the ETB engaged motor and the attraction roller. The attraction roller transfer positive dc bias to the media so that the negatively charged toner can be easily transferred from the drum to the sh[...]

Figure 4-15 Separation from the drum Step 8: separation from the ETB The elasticity of the print media causes it to separate from the ETB. The static-charge eliminator is not involved during this step. Fusing stage Until the fusing stage is complete, the image is not permanently affixed to the print media. The toner can be easily smudged until the [...]

Step 10: drum cleaning The cleaning blade scrapes the residual toner off the surface of the photosensitive drum and deposits it in the waste-toner container. The drum is now clear, and is ready for the next image- formation process. Print cartridge This printer has four print cartridges: magenta (M), cyan (C), yellow (Y), and black (Bk). Each cartr[...]

Print-cartridge activation A memory tag is a nonvolatile memory that is built into the print cartridge. The DC controller reads and writes data that is stored in the memory tag. The DC controller reads data at the following times: ● When the power is turned on ● When someone closes the front cover ● When it receives a command from the formatt[...]
