Comptia A+ 901 Printers

(laser, inkjet, thermal, and impact)

False. A duplexing assembly (not a transfer belt) is required to print twosided output on a laser printer. Many inkjet printers also use duplexing assemblies to print two-sided paper. A transfer belt is used on some high-end color laser printers. Colors are applied to the transfer belt and then to the paper. This step is repeated for different colors

True. The fuser assembly generates heat, which melts the plastic particles in the toner and fuses them onto the paper.

True. This is the proper order of the laser printer imaging process.

False. The image is written onto the drum during the exposing stage, not the developing stage

True. During the transferring stage, toner is transferred from the imaging drum to the paper.

True. The fuser assembly melts the toner, so if the toner is not sticking to the paper, the most likely cause is a faulty fuser assembly. . The fusing assembly provides both friction and heat to the paper as it passes through, melting the toner onto the paper.

True. The erase lamp and scraper work together to remove remnants of the previous print job during the cleaning phase of the imaging process

False. Impact printers (not inkjet printers) use small pins to hammer ink onto a page from a ribbon.

True. Inkjet printers commonly have calibration programs that can be used to align the print heads when colors are misaligned. A calibration program performs electronic adjustments to improve the print quality Inkjet printers include one or more test pages that you can print to check the quality of the printouts. These usually include specific patterns, with notes on what to do if the printout isn't perfect.

True. Thermal printers use a special type of paper that responds to heat. The print head heats the paper to create the printout. The paper on thermal printers is typically wound around a spindle. The spindle is attached to a sprocket type of feed assembly, and as the printer prints, the sprocket turns, feeding the paper through the printer.

True. Impact printers use pins to print dots within a matrix, and by printing different dots, they can print characters and images

True. Impact printers are ideal for printing multipart forms using carbon or carbonless paper to create multiple copies at a time.Many businesses use multipart forms that have carbon paper between each copy. When the print head strikes the top paper, the force is felt through each page and presses the carbon paper onto the other copies.

True. Impact printers often use continuous feed paper with holes along the sides. The tractor feed mechanism has sprockets that fit into these holes to pull the paper through. Impact paper used in impact printers can be continuous feed paper or individual sheets. When continuous feed paper is used, the paper is fed through the printer with the tractor feed mechanism. Single sheets of impact paper are fed through with friction from the platen, similar to how paper was fed through old typewriters. For best print quality, continuous feed paper and a tractor feed mechanism are used to ensure the paper is fed through at a consistent rate. Continuous feed paper is available with carbon paper to print multipart forms, or multiple copies at the same time.
