Abstract: A medium supporting mechanism includes a medium supporting unit and a medium holding unit. The medium supporting unit includes a support face that supports a medium, a guide rail intersecting a transport direction in which the medium is transported, and an engaged portion positioned upstream of the first guide rail. The medium holding unit includes a holding portion that covers an edge of the medium in a width direction, an abutting portion movable between an abutting position and a separation position, a switching portion that switches a position of the abutting portion between the abutting position and the separation position, and an engaging portion engageable with the second guide rail. The medium holding unit includes a pressing portion downstream of the abutting portion in the transport direction. The pressing portion presses the support face to move a position of the holding portion in a direction away from the support face.

Abstract: A sheet supplying apparatus, which is capable of winding a sheet tightly, includes a driving unit configured to cause a roll including a wound consecutive sheet to rotate in a first direction for feeding the sheet or a second direction opposite to the first direction, a sensor that detects a leading end portion of the sheet separated from an outer circumferential surface of the roll, and a contact body that presses the outer circumferential surface. Before the sheet is fed, in a state in which the contact body presses the outer circumferential surface, the driving unit causes the roll to continuously rotate in the second direction until a detection cycle of the leading end portion by the sensor is less than a predetermined value.

Abstract: A direct heat vacuum platen having a main case with an open top portion, a print surface having a main top configured to fit over the open top portion of the main case, the main top having a rectangular arrangement of suction ports configured to secure an above print substrate using suction provided from vacuum fans attached to the main case, heating elements attached to a bottom portion of the main top, a thermoregulator having a thermostat controller attached to temperature sensors and the heating elements within the main case, and a power controller having a power slot attached to a power switch and main fuse holder, a fan fuse holder, the thermostat controller and the suction fans. The suction ports are configured to hold a print substrate of a desired size. The usage of the internal vacuum fans reduces noise and power usage when compared to external vacuum apparatuses.

Abstract: A printing system comprises an ink deposition assembly, a media transport device, and an airflow control system. The ink deposition assembly comprises printheads to deposit a print fluid, such as ink, on print media, such as paper, transported through a deposition region. The media transport device holds the print media against a movable support surface, such as a belt, by vacuum suction through holes in the media transport device and transports the print media though the deposition region. The airflow control system comprises one or more valves that are actuatable between an open state and a closed state, each valve blocking a subset of the holes in the closed state. The airflow control system also comprises one or more actuators to actuate the valve(s). The actuator(s) selectively actuate the valve(s) between the open and closed states based on a position of an inter-media zone between adjacent print media.
