Abstract
A printing apparatus includes a head, a carriage, an encoder including a scale, a first light emitting element and a first light receiving element, a measuring sensor including a second light emitting element and a second light receiving element, and a controller. The controller is configured to perform a printing operation of causing the head to eject ink while moving the carriage based on a signal output by the encoder, a measuring operation of moving the carriage based on a signal output by the encoder, causing the second light emitting element to emit light onto a measuring position of the scale, and receiving light reflected from or passing through the measuring position using the second light receiving element, and a calculating operation of calculating lifetime of the scale based on a light amount received by the second light receiving element.
