Answer Key

Inkjet printer

Section A: Quick Questions

A — It sprays tiny droplets of liquid ink through nozzles in a print head

A — Cyan, magenta, yellow and black

B — It moves across the paper, spraying ink through its nozzles

A — To spray tiny droplets of ink onto the paper

B — They are cheap to buy but the ink cartridges are expensive to replace

Section B: Match the Pairs

Inkjet printer → Sprays tiny droplets of liquid ink through nozzles in a print head onto paper as the head moves across it

CMYK cartridges → Cyan, magenta, yellow and black ink supplies that an inkjet printer mixes to print colour pages

The print head has many tiny nozzles that fire droplets of ink onto the paper as it moves across the page → print_head.moveAcross(paper); nozzles.sprayInk()

An inkjet printer is cheap to buy but the replacement ink is expensive, and it is slow for large print jobs → printerCost = LOW; inkCost = HIGH; bigJobSpeed = SLOW

An inkjet printer uses a laser and toner powder to make the image → This describes a laser printer. An inkjet printer sprays droplets of liquid ink through nozzles in a print head.

Inkjet cartridges: red, green, blue and white → The inks are wrong. An inkjet printer uses cyan, magenta, yellow and black cartridges.

Section C: Definitions

Inkjet printer — Sprays tiny droplets of liquid ink through nozzles in a print head onto paper as the head moves across it. Uses cyan, magenta, yellow and black cartridges.

Section D: Fill in the Blanks

Inkjet: print head sprays droplets of ink

The print head has tiny nozzles for ink

Cartridges: cyan, magenta, yellow, black

Inkjet is good for photo quality prints

Low cost to buy, but ink is expensive

Section E: Spot the Error

B — An inkjet printer uses cyan, magenta, yellow and black (C, M, Y, K) cartridges, not red, green and blue. It should be cartridges = C, M, Y, K.

A — An inkjet printer sprays liquid ink. Powder is toner, which laser printers use. It should be ink = liquid.

B — An inkjet printer has a print head that moves across the paper. A drum belongs to a laser printer. It should be head.move_across(paper).

B — Inkjet printers are cheap to buy, but the replacement ink is expensive. It should be cost_of_ink = HIGH.

C — Inkjet printers give good quality photo printing because the tiny ink droplets blend colours well. It should be quality = GOOD.
