What do all of the components of a dot a matrix printer do?
power supply board – provides regulated power of different voltages for various components of printer. power transformer – transforms input voltage to a higher or lower voltage required for the power supply to use. main control board – controls the various components of the printer to work together in order to print and to process the incoming data into a format the printer can use paper motor feed – usually a stepper motor that controls how fast and when the paper is advanced home position sensor – detects when the print head/carriage is positioned in a certain location (usually to one side) so it knows where the printhead is to start print on a line timing belt – usually used to move the printhead/carriage in a fixed and controlled motion printhead assembly – the print mechanism that contains the pins that are moved back and forth across the paper and fired at the correct times to create characters using dots printhead positioning motor – the motor that drives the printhead back and
