According to one embodiment, a tablet printing apparatus includes: a conveyor belt configured to convey a tablet; a print head configured to perform printing on the tablet conveyed by the conveyor belt; and a belt-position detector configured to detect the position of the conveyor belt in a direction crossing the conveying direction of the tablet in a horizontal plane. The conveyor belt includes a plurality of holes arranged in a row along the conveying direction of the tablet to hold the tablet. The belt-position detector includes an imaging device configured to capture an image of two or more of the holes; and an image processing device configured to detect the position of the conveyor belt in the crossing direction based on the image captured by the imaging device.

A method of controlling a print apparatus configured to convey a sheet to a static elimination apparatus configured to perform static elimination processing on the sheet includes performing control, in a case where a jam of the sheet occurs, to stop print processing, and displaying at least an occurrence position of the jam and information prompting a user to check a static elimination setting.

An inkjet recording apparatus includes: a tank having an ink chamber; a recording head; a memory; a display; an operation interface; a power switching section; and a controller. The power switching section is configured to be switched between a first state where an electric power is supplied to the recording head and the display and a second state where supply of an electric power to the recording head and the display is interrupted. After the power switching section is switched from the second state to the first state, the controller executes a query process to: display a query screen inquiring whether the ink chamber has been refilled with ink; and receive one of a first operation and a second operation. In response to receiving the first operation indicating that ink chamber has been refilled with ink, the controller executes an initialization process to initialize a count value.

An interlock circuit comprises a plurality of semiconductor switching units electrically connected or connectable in series in a supply line, a plurality of control units electrically connected to the plurality of semiconductor switching units, and a trigger unit electrically connected to the plurality of control circuits. Each control unit activates or deactivates a corresponding semiconductor switching unit in response to trigger signal received from the trigger unit.

Disclosed herein is a mobile printer freefall detection and protection mechanism. Printers may be subject to vibration or free fall during printing. This is more likely to happen for a mobile printer. In such cases, the printing performance will be adversely affected a lot or a thermal printhead (TPH) in the printer could be damaged. This disclosure describes a system and method of solving this problem by measuring the G-forces at using at least one sensor to determine if it is safe to start operation again.
