摘要： A nozzle testing device includes: a two-dimensional image sensor to capture an image of a pattern formed on a recording object by discharging ink from a nozzle row while moving the nozzle row and the recording object relative to each other in a direction orthogonal to the nozzle row; a light source unit provided such that regularly reflected light by the pattern forms a regular reflection area in the image of the pattern captured by the two-dimensional image sensor; and a detection unit to analyze the image to detect discharge failure of the nozzles. The regular reflection area is formed in the image such that a dimension in a direction corresponding to the direction of relative movement between the nozzle row and the recording object is greater than a dimension in a direction orthogonal to the direction corresponding to the direction of relative movement in the image.

摘要： An image forming apparatus using a roll includes a power shutdown operation detector to detect an operation of shutting down power supply to the apparatus; a power supply switching unit to switch power supply condition to the apparatus; and an apparatus controller to control the apparatus. The apparatus controller controls a roll setting operation to set the roll ready for an image outputting operation, and controls the power supply switching unit based on detection of an operation that shuts down the power supply. The apparatus controller confirms whether the power shutdown operation detector detects the power shutdown operation when the roll setting operation is being conducted. When an operation that shuts down the power supply is detected, the apparatus controller aborts the roll setting operation and shuts down power supply to the apparatus.
