f) Paper feed assembly
The paper feed assembly consists of paper feeding mechanisms, such as a feed roller that is driven by the feed motor and a pinch roller unit that follows up the
motion of the feed roller.
Paper feeds horizontally under the printheads on the carriage as it is kept level on the platen to prevent cockling.
