What are the steps for electrophotography?
1. Charging(electric charges uniformly form on the whole surface of the image drum)
2 Exposure(the printing pattern is written in dots(dpi) with light and an electrostatic latent image is formed on the image drum
3 Developing(toners are adhered to the lat
how do you identify electrophotography under magnification?
You can see "satellite" extraneous toner particles around the edge of images in the non image
What are the two ways inkjet can work?
Continuous flow and drop on demand
What are the two types of drop on demand?
Thermal Bubble and piezoelectric
Thermal Bubble
heats a resistor and expands an air bubble
Piezoelectric
charges crystal that expands
how to identify inkjet under magnification
can see the influence of the round ink squirts around the edge if type or can see the matrix grid pattern of the ink squirts in solids
Markets of electrophotography and inkjet
