7.1.8 Practice Questions Printers

Why would you recommend a dye sublimation printer?

When print jobs are detailed photographic reproductions. Explanation Dye sublimation printers produce images by heating a coloured dye, transferring the dye in gas form to paper where the dye cools and solidifies. This process is ideal for producing photographic quality images on a variety of media. Dye sublimation printers are typically more expensive than other types of printers, print on special photographic paper, and take over one minute to produce a single page.

Which of the following would be a good reason to not recommend a solid ink printer?

The user has a surplus of toner cartridges and would like a printer that can be used with these. Explanation Solid ink printers do not use any form of toner powder to produce their images. Solid ink printers produce images by melting an ink stick onto a print head that is transferred to a drum in liquid form, where it is applied to paper and dries. Solid ink printers typically produce high speed, high quality images on a wide variety of media at relatively inexpensive prices. While solid ink printers cannot produce images on photographic paper they can produce high quality photographic images.

Which of the following printers would produce the highest print quality?

600 DPI Explanation The dots per inch (DPI) describe the level of detail produced by a printer. The higher the DPI, the higher the print quality.

Which type of printer heats the ink in its head to print?

Bubble jet (inkjet) Explanation The bubble jet inkjet printer applies heat to the ink and squirts it through tiny nozzles in the print head and onto the paper. A laser printer also uses heat, but the heat is applied to thermal rollers (not a print head). A piezoelectric printer uses pressure, not heat, to apply the ink. A thermal printer uses heat to cause a reaction on specially treated paper.

You have been asked to recommend a printer that will be used in a travel agency. The printer will be used to print airline tickets. Each ticket has four pages (multi-part, carbon-based forms), and the same information must show up on all four pages with a single pass of the printer. Which printer type would you recommend?

Impact Explanation Because dot matrix (impact) printers strike the image onto paper, they are good printers to use when carbon-copy documents are being printed. A dye sublimation printer uses film-embedded dye. Laser printers use lasers and electrical charges to transfer images to paper. Ink jet printers spray ink from ink stored in a reservoir.

Which type of printer uses a drum, plastic toner, and fuser to create a printed page?

Laser Explanation Laser printers use a laser to charge a metal drum. The drum picks up plastic toner, and the toner is then fused onto the paper (using rollers and heat). Dot matrix printers use an inked ribbon. The printing mechanism strikes the ribbon to put ink onto the paper. A dye sublimation printer is a non-impact printer that uses film-embedded dye. Ink jet printers are quiet non- impact printers with ink stored in a reservoir.

Which type of printer uses lasers and electrical charges to transfer images to paper?

Laser Explanation A laser printer uses lasers and electrical charges to transfer images to paper. A thermal inkjet printer applies heat to the ink in print head nozzles causing the ink to boil and expel itself itself from the nozzle. A piezoelectric printer uses pressure, not heat, to apply the ink. A dot matrix printer uses pins striking the ink ribbon to transfer the ink.

Which component in a laser printer prepares the photosensitive drum for writing by causing it to receive a negative electrostatic charge?

Primary corona Explanation The primary corona (also called the main corona or the charge corona) prepares the photosensitive drum for writing by causing it to receive a negative electrostatic charge. Depending on the printer, the primary corona will be wires or rollers. The Organic Photoconductor (OPC) drum is just another name for the photosensitive drum. The transfer corona (sometimes called the secondary corona) charges the paper to attract the toner. Fusing rollers attach the toner to the paper by pressing and melting.

Which component in a laser printer charges the paper to attract toner?

Transfer roller Explanation The transfer roller charges the paper to attract the toner. The primary corona prepares the photosensitive drum fro writing by causing it to receive a negative electrostatic charge. Depending on the printer, the primary corona will be wires or rollers. A laser beam changes the charge on the surface of the drum in a pattern of the page's image. The toner sticks to the charged areas on the drum. Fusing rollers attach the toner to the paper by pressing and melting it.

Which component in a laser printer applies toner to the drum, causing the toner to stick to the charged areas on the drum?

Developing roller Explanation The developing roller applies toner to the drum. The toner sticks to the charged areas on the drum. The transfer roller charges the paper to attract the toner. The primary corona prepares the photosensitive drum for writing by causing it to receive a negative electrostatic charge. Depending on the printer, the primary corona will be wires or rollers. Fusing rollers attach the toner to the paper by pressing and melting it.
