A printing apparatus includes: a holder configured to hold a medium; a conveyor configured to convey the holder; a printing device configured to print on the medium conveyed by the conveyor in response to a reception of a print instruction; and circuitry configure to: maintain the printing device in a busy state; receive the print instruction in the busy state; control the conveyor to start conveying the holder to a print start position in response to a reception of the print instruction in the busy state; hold the holder at the print start position in the busy state; and control the printing device to start printing on the medium in response to a release of the printing device from the busy state.

Printing apparatus and printing method

In an image forming apparatus, a sub-scanning carriage moves a recording medium in a conveyance direction. A first carriage and a second carriage move in a main scanning direction and discharge a liquid and another liquid onto the recording medium to print a first image and a second image on the recording medium, respectively. Circuitry executes a first print sequence and a second print sequence. Further, the circuitry calculates a drying time of the liquid to form the first image by the first carriage, determines whether to execute the second print sequence based on the drying time, causes the first carriage and the second carriage to execute the second print sequence when the circuitry determines to execute the second print sequence, and causes the first carriage and the second carriage to execute the first print sequence when the circuitry determines not to execute the second print sequence.

Image forming apparatus

A liquid discharge apparatus includes a liquid discharge head configured to discharge a liquid, a liquid cartridge configured to store the liquid to be discharged from the liquid discharge head, a holder to which the liquid cartridge is detachably attachable, a timer configured to countdown a time, and circuitry configured to control the liquid discharge head to discharge the liquid as a discharge operation, control the liquid discharge head to stop the discharge operation, determine an attachment or a detachment of the liquid cartridge to or from the holder while the discharge operation is stopped, control the timer to prepare countdown of the time in response to a detachment of the liquid cartridge from the holder, and control the liquid discharge head to continue stopping the discharge operation in response to an attachment of the liquid cartridge to the holder before the time has reached zero.

Liquid discharge apparatus, liquid discharge method, and non-transitory recording medium

A liquid discharge apparatus includes a platen to hold a medium; a liquid discharge head to discharge a liquid onto the medium on the platen according to discharge instruction information containing a type of the platen as a designated platen type; an operation panel to display a selection operation screen in which a type of the platen is selectable from the multiple platen types as a selected platen type; and circuitry to: control the operation panel to display the selection operation screen; determine whether the selected platen type matches a first specific platen type; determine whether the designated platen type matches a second specific platen type; control the operation panel to display warning in response to a determination; and control the liquid discharge head to continue to discharge the liquid in response to a determination.

Liquid discharge apparatus and liquid discharge method

An information processing device includes circuitry. The circuitry is configured to control a temperature of a heater. The heater performs heating in a printing process. The circuitry is further configured to measure an elapsed time from satisfaction of a given condition, and to determine whether the elapsed time is equal to or longer than a given time. The circuitry is configured to cause the temperature of the heater to rise based on a determination that the elapsed time is equal to or longer than the given time.

Information processing device, image forming apparatus, image forming system, information processing method, and non-transitory computer- readable storage medium

An image forming apparatus includes a conveyance unit configured to convey a recording medium; a reversing unit configured to reverse front and back sides of the recording medium; a recording head configured to reciprocatingly scan to form a first image on a first side of the recording medium, which is reciprocatingly conveyed by the conveyance unit at a first conveyance speed V, and a second image on a second side of the recording medium, which is conveyed at a second conveyance speed Vand ejected, in a case of performing a double-sided printing; and a control unit configured to control the first conveyance speed Vand the second conveyance speed Vto satisfy a relation&#x2266;()&#xd7;2,where t is a scanning time required for one reciprocation of the recording head, and W is an image formation width of the recording head.

Image forming apparatus and image forming method

An image forming apparatus is disclosed that forms an image based on a control signal from an image processing controlling unit that processes input image information into image data. The apparatus includes a carriage that moves in a main scanning direction in accordance with the control signal; a conveyance unit that conveys a recording medium in a sub-scanning direction; an output detection unit that detects motor outputs of the carriage at any plural points when the carriage moves at a constant speed; and a jamming determination unit that compares an average value of the motor outputs of the carriage between the plural points with a predetermined tolerance to determine a conveyance failure.

Image forming apparatus, image forming system, image forming method, control program for eliminating conveyance failure, and information recording medium having recorded thereon control program for eliminating conveyance failure

An image forming apparatus, an image forming method, and a control program therefor. The apparatus includes an image processing control unit to process image information sent from an external device, a carriage to move in a main scanning direction according to a control signal sent from the image processing control unit and having a nozzle to discharge an ink onto a recording medium, a conveyance unit to convey the recording medium in a sub-scanning direction, and a conveyance failure detection unit to detect a status of the recording medium. The image processing control unit identifies a type of a conveyance failure among a plurality of types of conveyance failures based on the status of the recording medium output from the conveyance failure detection unit and sends a conveyance failure correction signal to perform an operation for retracting the carriage to a predetermined or desired position in the main scanning direction.

Image forming apparatus, image forming method, and control program for controlling a carriage upon conveyance failure

In an image forming apparatus, a control unit determines that dirt is present on the linear scale when a detecting unit detects a change in a moving direction of a moving member while the moving member is moving at a constant speed.
