Q

Define Printer Calibration

A

Process by which the printer determines the print density of colour balance to use, usually automatic and has a button to do it for you

23
Q

Why is an Inkjet printer’s name what it is

A

Creates an image on the paper through a nozzle or jet on a printhead onto a paper

24
Q

What is a slightly more expensive alternative to thermal method that requires less replacing

A

Piezoelectric method

25
Q

Why do you save money in the long run with the piezoelectric method

A

Ink carts are cheaper

26
Q

Define Inkjet roller

A

Responsible for advancing the paper through the printer

27
Q

Define Inkjet feeder

A

Allows multiple pieces of paper in a tray to be heled , whilst also letting one piece of paper pass at a time while using the roller

28
Q

Define Carriage Belt/Carriage System

A

Allows the printhead to move back and fourth across the page

29
Q

What is the only variation that you will see with Inkjet printers

A

Uni-directional printing or Bi-directional printing

30
Q

Define Unidirectional Printing

A

Only prints left to right

31
Q

Define Bidirectional printing

A

Printhead will apply ink from left tor right and right to left - is faster

32
Q

What are the 2 types of Inkjet printer

A

Piezoelectric and Thermal

33
Q

Difference between Inkjet and Laser

A

Line printer instead of page printer, higher cost/page with Inkjet

34
Q

What do most manufacturers include built into the Inkjet Cart

A

A sensor, warning for low ink count

35
Q

Define thermal printer

A

Type of printer that uses a heating element to create an image

36
Q

Difference between Inkjet and Thermal printer when displaying the image on the page

A

Inkjet heats the ink which is then transferred to the page whereas the thermal actually heats areas of the page to display the image, no ink is involved

37
Q

What are thermal printers usually used for

A

printing receipts

38
Q

2 types of thermal output

A

ribbons and thermal paper

39
Q

What determines the quality of the thermal print output and how is it measured

A

Number of prints the printhead contains , DPI (Dots per inch) e.g. 200 dpi

40
Q

What can you use to clean the thermal printhead

A

isopropyl alcohol

41
Q

What measurement is used for impact printers

A

DPI

42
Q

Define tracks

A

Series of holes going down the side of the paper with a perforation between the regular paper and tracks

43
Q

Define tractor feed

A

Exists on both sides of the printer and pulls the paper through the printer uses tractor fed paper

44
Q

Common use of impact printers

A

Multipart forms printed at the same time

45
Q

Define 3D printer

A

Printer that creates images in 3 dimensions (depth, width, height)

46
Q

Common building materials for 3 printing

A

plastic / resin

47
Q

Define slice

A

one layer of the overall 3D model

48
Q

Define print bed/ build plate

A

flat plate where the material will be extruded and built

49
Q

define bed / build surface

A

sheet placed on top of the base plate that will hold the object into position while printing

50
Q

Define extruder

A

Printhead for 3D printers

51
Q

Define Gears, Motors and motion control

A

Stays in pace or moves up, down, left, or right

52
Q
