Cyan, Magenta, Yellow, and Black
How is the quality printing measured?
9.1.1.1

Name 6 printer connection types?
9.1.1.2
Serial Parallel Ethernet Firewire - transfer rate of up to 400 Mb/s USB SCSI - Small Computer System Interface
True or False
Does an inkjet printer spray ink on a paper?
9.2.1.1
True - through a tiny hole at the nozzle
What are the two types of injet nozzles?
9.2.1.1
Thermal - A pulse of electrical current is applied to heating chambers around the nozzles
Piezoelectric - Piezoelectric crystals are located in the ink reservoir at the back of each nozzle. A charge is applied to the crystal, causing it to vibrate. This vibration of the crystal controls the flow of ink onto the paper.
What are the 7 stages of laser printer?
9.2.1.2
1) Processing - The data from the source must be converted into a printable form.
2) Charging - The previous latent image on the drum is removed and the drum is conditioned for the new latent image.
3) Exposing - To write the image, the photosensitive drum is exposed with the laser beam.
4) Developing - The toner is applied to the latent image on the drum.
5) Transferring - The toner attached to the latent image is transferred to the paper. A corona wire places a positive charge on the paper.
6) Fusing - The toner is permanently fused to the paper. The printing paper is rolled between a heated roller and a pressure roller.
7) Cleaning - When an image has been deposited on the paper and the drum has separated from the paper, the remaining toner must be removed from the drum.
