    Xerox, Hewlett-Packard, and Canon were pioneers in developing the laser printer technology we use today. Scientists at Xerox developed the electrophotographic (EP) imaging process in 1971. HP introduced the first successful desktop laser printer in 1984, using Canon hardware that used the EP process. This technology uses a combination of static electric charges, laser light, and a black powdery ink-like substance called ______. Printers that use this technology are called EP process laser printers, or just laser printers. Every laser printer technology has its foundations in the EP printer imaging process. Let’s discuss the basic components of the EP laser printer and how they operate so that you can understand the way an EP laser printer works.

    Laser Printers Laser printers and inkjet printers are referred to as ______ because they receive their print job instructions one page at a time rather than receiving instructions one line at a time. There are two major types of page printers that use the electrophotographic (EP) imaging process. The first uses a laser to scan the image onto a photosensitive drum, and the second uses an array of light-emitting diodes (LEDs) to create the image on the drum. Even though they write the image in different ways, both types still follow the laser printer imaging process. Since the A+ exam focuses on the laser printer imaging process and not on differences between laser and LED, we’ll focus on the same here.

    Study Notes

    Types of Impact and Inkjet Printers

    • Daisy-wheel printers are among the oldest printing technologies, containing a wheel with raised letters and symbols on each petal.
    • These impact printers have a slow speed, initially printing only two to four characters per second, and produce a lot of noise.
    • Daisy-wheel printers allow printing on multipart forms and are relatively inexpensive compared to laser printers of the same vintage.
    • Dot-matrix printers work similarly to daisy-wheel printers, with a print head containing a row of pins triggered in patterns to form letters and numbers.
    • Early dot-matrix printers have poor image quality referred to as draft quality, but as more pins were developed, the quality improved to near letter quality.
    • Dot-matrix printers are noisy but have a faster print speed, typically starting around 72 characters per second, and can use multipart forms.
    • Inkjet printers spray ink on the page to form the image and typically use a reservoir of ink, a pump, and a nozzle.
    • Older inkjet printers were messy, noisy, and inefficient, but the technology has improved, and they are commonly used for photo printing.
    • Inkjets are simple devices, containing fewer parts than dot-matrix printers, and are inexpensive to manufacture.
    • Inkjet printers have print head/ink cartridge, head carriage, belt, and stepper motor, paper feed mechanism, and control, interface, and power circuitry as their main parts.
    • Inkjet printers are now affordable, with some models priced at $40 to $50, offering print quality that rivals basic laser printers.
    • The term "bubble-jet printers" is copyrighted by Canon and refers to inkjet printers that spray droplets of ink in a high-definition dot-matrix pattern.

    Inkjet Printers: Components and Profit Model

    • Printer companies make the majority of their profits from ink cartridge sales, as cartridges have a high profit margin.
    • The print head in an inkjet printer contains small nozzles that spray ink onto the page, and it is usually part of the ink cartridge.
    • Ink cartridges have small chambers with pinholes used to spray ink on the page to form characters and images as patterns of dots.
    • There are two methods of spraying ink out of the cartridge: heating elements causing ink vaporization (HP method) and piezoelectric elements flexing when energized (Epson method).
    • After printing, the print head moves back to the maintenance station, which contains a small suction pump and ink-absorbing pad to keep the print head in working order.
    • The head carriage, belt, and stepper motor are components that make the print head move back and forth during printing, with the stepper motor moving in precise increments.
    • The paper feed mechanism picks up paper from the paper drawer and feeds it into the printer, consisting of pickup rollers and separator pads to ensure only one sheet goes into the printer.
    • The pickup rollers are turned on a shaft by the pickup stepper motor and are cleaned with mild soap and water, not alcohol.
    • Sometimes the paper fed into an inkjet printer is placed into a paper tray in the front of the printer, holding the paper until it is fed into the printer by the paper feed mechanism.

    Key Components of EP Printers

    • EP printers using EP imaging process contain nine standard assemblies: toner cartridge, laser scanner, high-voltage power supply, DC power supply, paper transport assembly, transfer corona, fusing assembly, printer controller circuitry, and ozone filter.
    • The toner cartridge holds toner, a black carbon substance mixed with polyester resins and iron oxide particles, and contains the EP print drum coated with a photosensitive material.
    • Toner also contains a medium called the developer, carrying the toner until used by the EP process.
    • Some laser printers have toner and photosensitive drum as a single unit, while others allow separate replacement.
    • Never ship a printer with a toner cartridge installed to avoid spillage and mess.
    • The laser scanning assembly exposes the EP photosensitive drum to light, discharging it only in the exposed area, thus scanning the image onto it.
    • Laser light is enclosed and only operates when the printer cover is closed to prevent eye damage.
    • The high-voltage power supply (HVPS) converts AC current from a standard wall outlet into higher voltages used during the EP process.
    • The DC power supply (DCPS) converts high voltages used in the EP process into low voltages for logic circuitry and motors.
    • The paper transport assembly consists of a motor and rubberized rollers for moving the paper through the printer.
    • The feed roller pushes one sheet into the printer, while the registration rollers synchronize paper movement with the image-formation process.
    • The transfer corona assembly is where toner sticks to the exposed areas on the photosensitive drum.

    Laser Printer Components and Functions

    • The transfer corona assembly transfers toner from the photosensitive drum to the paper using high-voltage charge.
    • It contains a static-charge eliminator strip to prevent paper from sticking to the EP cartridge and jamming the printer.
    • Two types of transfer corona assemblies exist: wire and roller, with the roller supporting higher speeds.
    • The fusing assembly uses pressure and heat from two rollers to fuse toner particles to the paper.
    • The fuser consists of a halogen heating lamp, Teflon-coated aluminum-fusing roller, and a rubberized pressure roller.
    • The printer controller assembly converts computer signals into commands for the printer's components using rasterizing.
    • Ozone, created by high-voltage coronas inside the printer, is removed by an ozone filter in older printers to prevent damage to components.
    • Most newer laser printers don't have ozone filters due to reduced ozone emissions from using transfer corona rollers.
    • Duplexing assembly allows modern laser printers to print on both sides of the paper.
    • The electrophotographic (EP) imaging process in laser printers consists of seven major steps, including processing, charging, exposing, developing, transferring, fusing, and cleaning.
    • Printing cannot start until the printer is in a ready state, indicated by an illuminated Ready LED light or a specific display message.
    • The processing step in EP imaging involves receiving the image from the computer and creating the print job accurately for producing the output.
