Inkjet printers.

– Ink cartridges.» Designed to work with specific printers.

• The main consumable resource of the inkjet printer.

• Color inkjets use the CMYK color process to produce the

RGB color spectrum.

– Print heads.» Fixed head: attached to the carriage, it is designed to last the

life of the printer.

» Disposable head: attached to the ink cartridge, it is designed

to be replaced when the ink cartridge is replaced.

– Carriage and belt assembly.» Carries the print head back and forth across the page.

– Rollers and feeders.» One or more roller designed to pick up paper from the paper

tray and feed it through the printer at a constant rate.

The duplex assembly allows for two sided printing.

An add on attachment for some inkjet printers, the

duplex assembly can be used when two sided

printing is desired. After the first side of the page is

printed, the duplex assembly will actually turn the

paper over and send it back through the printer. This

allows for the back side of the page to be printed

without user intervention.

Inkjet printers.

– They are the most common printer in the

small office/home office.» Relatively inexpensive printers that are easy to use and

maintain.

» Capable of producing good to very high quality print jobs.

• Some are capable of producing fine streams of ink that

achieve 1440 X 720 dots per inch (dpi).

– The two main types of inkjet printer.» Piezoelectric type printer: an electrical charge is applied to a

crystal in the print head, causing it to vibrate.

• This vibration causes the ink to spray out in a fine stream.

• The piezoelectric print head constantly has ink running

through it.

» Thermal or Bubble Jet printer: heat is used at the print head

to cause the ink to bubble.

• When the bubbles burst, a fine spray of ink occurs.

• The thermal print head only receives ink as needed for

printing.

Inkjet printers.

– The printing process.» The computer sends the print job to the printer as a

raster image.

• A raster is a line of dots that are used to make up a

portion of an image or character on a page.

• A raster image is all of the lines of dots that make up

an image or all of the characters on a page.

» The roller picks up a single page of paper and sends it

through the printer.

» As the paper passes by the carriage assembly, the ink is

applied to the page.

• The belt attached to the carriage assembly moves the

print head side to side, allowing the image or characters

to be formed by the ink line by line.

» If a duplex assembly is attached and two sided printing is

requested, it will turn the page over and send it back

through the printer for the other side to be printed.

– Safety first.» Always read the manufacturer’s maintenance and safety guides

before performing any maintenance.

– Ink cartridge replacement.» The most common maintenance task.

• Replace cartridges as required.

• Run the supplied calibration software after replacing

cartridges to ensure that quality print jobs are produced.

– Paper debris removal.» Paper dust and debris can easily clog a printer. In most cases,

using compressed air can clean this out of the printer; use eye

protection when blowing dust and debris out of the printer.

– Print head cleaning.» Most inkjet printers come with software that contains a print

head cleaning process. Run the cleaning cycle as required.

» With fixed print heads, it is possible to use isopropyl alcohol

and a cotton swab to clean off dried ink from the nozzle.

Inkjet cartridges are designed for the specific printer and are a consumable

of the printer. The print heads may be fixed or disposable. The carriage and

belt assembly move the print heads side to side, while the roller and feeder

move the pages through the printer. An add on duplex assembly may be

used if two sided print jobs are required.

Summary

Inkjet printers are the most common SOHO printer. There are two main

types of inkjet printer—the piezoelectric and the thermal printer. The

computer sends the print job to the printer as a raster image. The roller and

feeder send the paper through the printer. As the paper moves past the

print heads, the ink is applied to the page.

How inkjet printers work.

Safety is always the first consideration; always read the manufacturer’s

safety procedures. Replacing ink cartridges is the most common

maintenance task. Always run the print head calibration process after

replacing the ink. Cleaning out paper debris is another common

maintenance task. Run the print head cleaning cycle as required.
