Abstract: When at least a part of a cleaning region is located downstream of a contact position where a cleaner is in contact with a transport belt in a normal rotation direction of the transport belt during cleaning of a cleaning region, the control portion can perform cleaning position adjustment control to reversely rotate the transport belt so that an entire of the cleaning region is located upstream of the contact position in the normal rotation direction, before the cleaner is switched from a separation state to a contact state.

Abstract: A roller cleaning mechanism includes a cleaning member making contact with a conveying roller, a holder holding the cleaning member, a housing for the holder, and an urging member. The holder is supported on the housing swingably about a swing shaft parallel to the axial direction of a driving roller. The urging member urges the holder oppositely to the rotation direction of the conveying roller. When the conveying roller rotates, its rotative driving force keeps the holder at a cleaning position where a cleaning face of the cleaning member makes contact with the outer circumferential face of the conveying roller. When the conveying roller is halted, the urging force of the urging member keeps the holder at a retracted position where a part of the cleaning member different from the cleaning face makes contact with the outer circumferential face of the conveying roller.

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.

Abstract: A food product platform, system and method for supporting a food product thereon during printing. The platform has a first surface for supporting the food product thereon, the first surface having a surface topography configured to securely support the food product thereon; and a second surface supporting an attachment mechanism for removably coupling to a reciprocal attachment mechanism on a receiving arm of a printer, wherein the attachment mechanism prevents movement of the platform with respect to the receiving arm when coupled to the receiving arm. The food product platform is removably connectable to the receiving arm manually and without the use of tools.
