An image forming apparatus includes an obtaining unit configured to obtain information related to a resolution of an image to be formed, an image processing unit configured to execute image processing corresponding to the information on image data, an image forming unit configured to form an image based on the image data on which the image processing is executed by the image processing unit, an intermediate transfer member to which a measuring image formed by the image forming unit is transferred, a measurement unit configured to measure the measuring image transferred to the intermediate transfer member, a storage unit configured to store measuring image data, and a controller configured to control the image processing unit to execute first image processing on the measuring image data, control the image forming unit to form the measuring image, control the measurement unit to measure the measuring image, and control an image forming condition.

A hardware processor includes: a communication part connected to the hardware processor; a rasterization processing time predictor that predicts a rasterization processing time required for rasterization processing; an output setting information extractor that extracts output setting information from print information about each page and transmits the output setting information to the hardware processor; a warm-up start time calculator that calculates a warm-up start time at which the hardware processor starts warm-up processing in accordance with productivity information about the hardware processor; a warm-up start notifier that notifies the hardware processor of a start of the warm-up processing, when a current time reaches the warm-up start time; a rasterization processor that transmits image data to the hardware processor, the image data being generated by performing the rasterization processing for each page; and a print start notifier that notifies the hardware processor of a print start after the warm-up processing is completed.

The disclosure concerns a test apparatus comprising a drum (100) configured such that ink drops (200) deposited on the surface of the drum form a printed marking (210) on the surface of the drum. The test apparatus further comprises an ink removal unit (300) configured to remove ink from the surface of the drum. The drum is at least partially transmissive of light and a light source (800) is disposed inside the drum to controllably illuminate the drum.

In an image forming apparatus, when a processor starts to be supplied with a voltage in a first voltage range from a voltage generator, the processor executes start-up processing with an operation clock of a first frequency, and transmits a voltage adjustment instruction to the voltage generator. On receiving the voltage adjustment instruction, the voltage generator performs voltage adjustment to make the voltage supplied to the processor a voltage in a second voltage range. On completion of the voltage adjustment, the voltage generator transmits a completion notice to the processor. When communication related to the voltage adjustment does not end normally, the processor keeps the frequency of the operation clock at the first frequency to execute processing; thereafter based on the operation clock of the first frequency.

An image forming apparatus includes a detection section that detects a distance between the image forming apparatus and a portable terminal, and a controller. The controller determines whether the distance meets a predetermined condition, and controls operations relating to an image forming job if the detected distance meets the predetermined condition.

An imaging system may include an array of image pixels and verification circuitry. The verification circuitry may inject test voltages into the image pixel array during the photodiode reset operation. The test signals may then be read out using a correlated double sampling operation. Verification circuitry may compare the test signals to reference data to determine whether the imaging system is functioning properly (e.g., to determine whether the array of image pixels satisfies performance criteria). If the amount of mismatch between the test signals and the reference data exceed a predetermined threshold, the imaging system may be disabled and/or a warning signal may be presented to a user of the system.
