Abstract (en)

[origin: EP3403835A1] A printing apparatus includes a transport belt (23) which transports a medium in a transport direction, a first and a second scale portions (75a, 75b) which are provided along the transport direction, a first measuring unit (85a) which measures a relative moving amount with respect to the first scale portion (75a), a second measuring unit (85b) which measures a relative moving amount with respect to the second scale portion (75b), a first holding unit (80a) which is configured integrally with the first measuring unit (85a) and holds one side of the transport belt (23) to move along with the transport belt, a second holding unit (80b) which is configured integrally with the second measuring unit (85b), and holds the other side of the transport belt (23) to move along with the transport belt (23), and a control unit which determines whether or not a difference between a first moving amount measured by the first measuring unit (85a) and a second moving amount measured by the second measuring unit (85b) is equal to or greater than a reference value.
