An image forming apparatus includes heating and pressurizing rotary members, and a speed control unit. In a first mixed job to be executed in a first mode and where a first recording material is to be initially conveyed and a second recording material is to be conveyed subsequent to the first recording material, the speed control unit sets a conveyance speed of the first recording material to a second speed based on acquired grammage information and sets a conveyance speed of the second recording material to a first speed based on the acquired grammage information. In a second mix job to be executed in the second mode and where the second recording material is to be conveyed subsequent to the initially conveyed first recording material, the speed control unit sets the conveyance speed of the first and second recording materials to the first speed based on the acquired grammage information.

Fixing apparatus

An object is to print a high quality image with resistance to print misalignment. To this end, the image processing apparatus generates quantized data for printing a first dot pattern and a second dot pattern in an overlapping manner. The first dot pattern and the second dot pattern are lattice patterns varying in a combination of two basis vectors. In a combined dot pattern obtained by combining the first and second dot patterns, there is a neighboring dot in which a dot in the first dot pattern and a dot in the second dot pattern are arranged at an interval smaller than a lattice spacing. The neighboring dot includes multiple neighboring dots varying in an approach direction.

Image processing method, image processing apparatus and storage medium generating a first dot pattern and a second dot pattern printed to overlap the first dot pattern by quantizing image data based on a threshold matrix

Formed is a dither pattern that makes it possible to output an image with excellent dot dispersibility and reduced graininess regardless of controls after quantization processing. To this end, an extended pattern in which multiple divided pixels correspond to each of multiple pixels included in quantization data and one or more of the multiple divided pixels are determined as dot-arrangeable-pixels in which dots can be printed is generated. Thereafter, the thresholds of the dither pattern are set based on the extended pattern in which the dots are arranged to obtain predetermined dispersibility.

Dither pattern forming method, image processing apparatus, and image processing method

A first dot pattern printed according to a result of quantization performed on a multi-valued grayscale value by using a first threshold matrix and a second dot pattern printed according to a result of quantization performed on multi-valued grayscale value by using a second threshold matrix are printed on a print medium in an overlapping manner. In order to generate the threshold matrices, a first initial pattern being a dot pattern corresponding to a first grayscale value and a second initial pattern being a dot pattern corresponding to a second grayscale value lower than the first grayscale value are generated for pixel regions of the first and second threshold matrices. Then, thresholds of the first and second threshold matrices are set such that dot patterns having continuity with the first and second initial patterns are obtained at grayscale values between the first and second grayscale values.

Image processing method, image processing apparatus and storage medium

In a printing apparatus configured to print an image by bidirectional multipass printing while using multiple print element rows that apply color material of the same color, a high-quality image suppressed in hue unevenness and density unevenness is printed. To this end, the printing apparatus forms first and second dot patterns on a print medium in an overlapping manner. In the first dot pattern, dot arrays in which first dot groups are arranged at an interval Bare arranged in a nozzle arrangement direction while being shifted from each other by Cin a scanning direction of a print head. In the second dot pattern, dot arrays in which the first dot groups are arranged at the interval Bare arranged in a nozzle arrangement direction while being shifted from each other by Cin the scanning direction of the print head. Here, values of Cand Care different.

Connector

An image reading apparatus includes: at least one processor configured to: set reading resolutions in a first and a second directions when reading an image of a document; determine an inclination amount of the document; correct an image to reduce the inclination amount; output image data indicative of an corrected image; and obtain information relating to a first direction length of the document. In a case where the first direction length of the document is less than a predetermined length and the processor outputs the image data indicative of the corrected image, whose resolution in the first direction is a first resolution and resolution in the second direction is a second resolution lower than the first resolution, the processor sets the reading resolution in the second direction to a third resolution higher than the second resolution.

Image reading apparatus and image forming apparatus

A connector assembly comprises a first connector and a second connector connectable to each other. The first connector comprises first terminals each having a first contact portion, a first shell having a first mating portion and a first engagement member formed with an engagement recess. The second connector comprises second terminals each having a second contact portion, a second shell having a second mating portion and a second engagement member having an engagement projection. Under a connected state where the first connector and the second connector are connected to each other, the first mating portion and the second mating portion entirely enclose contact areas in a perpendicular plane (YZ-plane) at which the first contact portions are in contact with the second contact portions. Under the connected state, the engagement projection and the engagement recess are engaged with each other to lock the connected state.

Connector assembly

An information processing apparatus includes sensors for detecting a plurality of types of errors. The information processing apparatus identifies a type of an error detected by one of the sensors, acquires a result of diagnostic processing corresponding to the identified type of the error, and outputs error information indicating the identified type of the error, and diagnostic information about a component corresponding to the result of the diagnostic processing.
