Abstract
Official abstract text for this publication.
A printing apparatus includes: a printing unit that performs printing on a printing medium; a drive unit that causes the printing unit to move; a power supply unit that supplies power to the drive unit; a detection unit that detects the movement of the printing unit; and a controller that controls an initialization operation related to the printing unit based on a detection result of the detection unit. When power supply from the power supply unit to the drive unit is started, the controller acquires the detection result obtained when power is not supplied, performs the initialization operation in a case where a movement of the printing unit is detected in the detection result, and does not perform the initialization operation in a case where a movement of the printing unit is not detected in the detection result.
First claim
Opening claim text (preview).
What is claimed is: 1 . A printing apparatus comprising: a printing unit that performs printing on a printing medium; a drive unit that causes the printing unit to move; a first power supply unit that supplies power to the drive unit; a detection unit that detects the movement of the printing unit; a second power supply unit that supplies power to the detection unit; and a controller that controls an initialization operation related to the printing unit based on a detection result of the detection unit. 2 . The printing apparatus according to claim 1 , wherein the power supplied from the second power supply unit is lower than the power supplied from the first power supply unit. 3 . The printing apparatus according to claim 2 , wherein the second power supply unit is a secondary cell.
