Maintain equipment and consumables

ICAITU007B Maintain equipment and consumables

Preventative Maintenance
It is important to maintain equipment and consumables. Routine or preventative maintenance ensures that the computer equipment will remain in good working order. Examples of preventative maintenance on computer equipment is the cleaning of your keyboard, monitor and mouse.
The keyboard can be cleaned by turning the keyboard upside down and gently tapping the bottom of the keyboard. Monitors can be cleaned with a damp cloth. The mouse requires regular maintenance as the tracking ball under the mouse collects dust as it rolls inside the mouse. To clean the mouse, turn it upside, remove the panel, clean the tracking ball and the rollers inside the mouse.
Printers require routine maintenance as well. Clearing out paper jams, changing cartridges and cleaning the printer will lengthen the life of your printer. Most printers have a print head cleaning function or you can use a print head cleaning kit. Make sure that you read the manufacturer's instructions before you perform any maintenance.
Consumables like floppy disks, CD's and paper require correct storage to ensure that they will be usable when required. They should be stored in a clean, dry area. To ensure that the moisture content of the paper is kept at an optimum level, paper should be stored in a sealed container. Moist paper tends to curl and jam in the paper path of a printer.




Backup
A method of storing files for use in an emergency The backup medium includes tape, disk or CD
Defrag
Defragmentation is the process of locating the non contiguous fragments of data into which a computer file may be divided as it is stored on a hard disk, and rearranging the fragments and restoring them into fewer fragments or into the whole file.

Hard Copy
The output from software applications printed and stored on paper.
Inventory
A record of items in stock This is used to track consumables or to accurately describe devices.
Maintenance
Maintenance refers to rectifying faults and changing settings or components to ensure that equipment continues to work effectively.
Non-routine Maintenance
When a device or its components are serviced to rectify a specific fault Procedures such as replacing a faulty floppy disk drive or adding extra RAM to a poorly performing computer are some examples of non-routine maintenance.
Print Server
A network node which stores print jobs and then passes them to the printer This action frees up the network from the slow printer output speed causing network congestion.
Printer Bubble Jet
A printer which uses the process of spraying the ink onto the page by superheating a bubble of ink to eject the spray onto the paper
Printer Dot Matrix
An impact printer that uses a series of pins to press an inked ribbon onto the paper surface to create a character or image
Printer Driver
The software the printer uses to interpret the signals from the various applications that have the ability to output hard copy.
Printer Impact
A printer that forms the characters and images on the paper by physical contact They can be used to make a real time carbon copy.
Printer Ink Jet
A non-impact printer that sprays the ink onto the paper through a series of fine nozzles
Printer Laser
A printer that uses electrically charged powdered toner to create the image, which is then fused onto the paper using heated rollers. They are more expensive to purchase than ink jet printers, however they are often economical to operate.


Printer Networked
A printer that can be set up as a network node and store and then print jobs from a number of remotely connected computers.
Printer non-impact
A printer that does not cause an impression to be made on the page
Purchase Order
The initial order which is a record of the items to be ordered and the associated auditing details
Routine Maintenance
When a device or its components are serviced as a matter of course Procedures such as adding paper to the printer tray, cleaning the ink jet cartridges, aligning the print heads or changing toner cartridges are some examples of routine maintenance.
Scan Disk
Scandisk is a Windows utility used to check your hard disk for errors and to correct problems that are found.






A GLOSSARY OF KEY WORDS

Syllabus outcomes, objectives, performance bands and examination questions have key words that state what students are expected to be able to do. A glossary of key words has been developed to help provide a common language and consistent meaning in the Higher School Certificate documents.
Using the glossary will help teachers and students understand what is expected in responses to examinations and assessment tasks.
