Abstract
A printing apparatus includes an apparatus body, a carriage, an encoder, a detection target member, a detector, and circuitry. The encoder detects an amount of movement of the carriage in a main scanning direction. The target member on the carriage has a cutout portion halfway in the main scanning direction. The detector on the body detects the target member. The circuitry controls a position setting operation for setting a home position of the carriage based on a detection result of detection or non-detection of the target member. The circuitry measures an output pulse of the encoder from when the detection result changes from detection to non-detection until when the detection result changes from non-detection to detection, and determines whether a measured value of the output pulse is equal to or greater than a predetermined value set based on a width of the cutout portion in the main scanning direction.
