PRINTING APPARATUS AND CONVEYANCE APPARATUS

The invention relates to a printing apparatus and a conveyance apparatus. A printing apparatus includes a conveyance unit to convey a print medium, a belt, a tensioner, and a control unit. The belt transmits a driving force of a drive unit to the conveyance unit. The tensioner is displaceable and makes pressure contact with the belt to generate tension. The control unit controls driving of the drive unit in a state where the tensioner is in pressure contact with the belt. The control unit performs first control in which the drive unit is driven with a first control value, which is not based on a driving amount detected by a detection unit. Where the detection unit detects the driving amount, the control unit subsequently performs second control in which the drive unit is driven with a second control value, which is based on the driving amount detected by the detection unit. 打印设备和输送设备。打印设备包括用于输送打印介质的输送单元、皮带、张紧器和控制单元。皮带将驱动单元的驱动力传递到输送单元。张紧器是能够移位的，并与皮带形成压力接触以产生张力。控制单元在张紧器与皮带压力接触的状态下控制驱动单元的驱动。控制单元执行第一控制，在第一控制中，以不是
