Abstract
A liquid discharge apparatus includes a transport belt that transports a medium, a discharge section that discharges a liquid to the medium transported by the transport belt, a cleaning mechanism that cleans the transport belt, and a control section that controls the cleaning mechanism. The cleaning mechanism includes a web that abuts against the transport belt and wipes off the liquid on the transport belt, and a driving section that changes a wiping surface of the web that abuts against the transport belt. The control section performs a first operation of changing the wiping surface of the web that abuts against the transport belt a predetermined number of times within a cleaning period for cleaning the transport belt.

A liquid discharge apparatus comprising:
- a transport belt that transports a medium;
- a discharge section that discharges a liquid to the medium transported by the transport belt;
- a cleaning mechanism that cleans the transport belt;
- and
- a control section that controls the cleaning mechanism, wherein
- the cleaning mechanism includes
- a web that abuts against the transport belt and wipes off the liquid on the transport belt, and
- a driving section that changes a wiping surface of the web that abuts against the transport belt, and
- the control section
- performs a first operation of changing the wiping surface of the web that abuts against the transport belt a predetermined number of times within a cleaning period for cleaning the transport belt;
- acquires information on an amount of the liquid discharged from the discharge section toward the medium,
- determines the predetermined number of times based on the information,
- sets the predetermined number of times as a first number of times when the amount of the liquid is a first amount, and
- sets the predetermined number of times as a second number of times less than the first number of times when the amount of the liquid is a second amount less than the first amount.
A control method of a liquid discharge apparatus including a transport belt that transports a medium, a discharge section that discharges a liquid to the medium transported by the transport belt, a web that abuts against the transport belt and wipes off the liquid on the transport belt, and a driving section that changes a wiping surface of the web that abuts against the transport belt, the method comprising:
- changing a wiping surface of the web that abuts against the transport belt
- acquiring information on an amount of the liquid discharged from the discharge section toward the medium,
- based on the acquired information, determining a predetermined number of times to change the wiping surface of the web within a cleaning period for cleaning the transport belt, setting the predetermined number of times as a first number of times when the amount of the liquid is a first amount, and
- setting the predetermined number of times as a second number of times less than the first number of times when the amount of the liquid is a second amount less than the first amount.
