An image recording position of the recording unit is located above an image forming position of the image forming unit.

Printer

In a control system, a controller is configured to determine presence or absence of an obstructed area within the intermediate section, and control movement of the moving body in accordance with a selected one of controlling methods including a first and a second control methods. The first control method causes the moving body to move at a first constant speed in the processing section defined within the intermediate section and at a second constant speed faster than the first constant speed in at least a part of a non-processing section within the intermediate section and other than the processing section, the first control method being selected when the obstructed area is absent. The second control method causes the moving body to move at the first constant speed in the processing section and the non-processing section, the second control method being selected when the obstructed area is present.

Control system

A control system is configured such that a carriage that a processing head is mounted is driven by a motor and reciprocates. The motor is controlled by a controller. The controller reciprocates the carriage by selecting a control mode as a target mode based on temperature information related to temperature of the motor and controlling the motor in the target mode. The controller selects the target mode to be applied to the control of the motor for each of particular work units. The target mode is selected from a group of particular control modes. Each control mode in the group of particular control modes is a control mode in which a maximum temperature, which is estimated based on the temperature information, when the control of the motor using the selected control mode would be executed until the processing is completed, is less than a reference value.

There is provided a liquid discharge apparatus including: a head, a conveyer having a roller arranged at the downstream of the head according to a conveyance direction, and a controller. The controller is configured to carry out: a recording process, a first determining process to determine whether or not a predetermined time has elapsed since the recording process, a conveying process to convey a medium in if the first determining process determines that the predetermined time has elapsed, and a setting process to set a predetermined time based on a discharge amount of a liquid from a plurality of nozzles onto a recording area and a conveyance time for the conveyer to convey the medium from the recording area to the roller, before the first determining process.

Liquid discharge apparatus

An image recording apparatus including: a recording unit; an accommodation part configured to accommodate therein a plurality of recording media including first and second recording medium and having a support surface on which the plurality of the recording media is supported; a conveying path; a feeder roller contacting the recording medium in the accommodation part from above; a reversing path; a recording medium detection unit located above the support surface and between the feeder roller and a downstream end of the support surface in the conveying direction; and a controller configured to control the feeder roller so as to feed the second recording medium in a manner that a front end portion of the second recording medium overlaps a rear end portion of the first recording medium, when the recording medium detection unit detects the rear end portion of the first recording medium fed by the feeder roller.

Image recording apparatus

An image recording apparatus is configured to perform a conveying process of a recording medium using a conveying roller and a discharging roller, a recoding process of recording an image on the printing sheet when the conveying process is not performed, and an adjusting process. In the adjusting process, among a plurality of conveying processes performed within a period from the start of the conveying process for an n-th printing sheet until the timing which is after the start of the conveying process for an (n+1)-th printing sheet, the conveying amount of the printing sheet subject to at least one conveying process is adjusted such that a timing when the trailing end of the n-th printing sheet passes through the discharging roller is within one of the acceleration period and the deceleration period of the conveying process for the printing sheet.

When an image recording apparatus records an specific image over a boundary between a first dot formation range where dots are to be formed in a preceding recording operation of two consecutive recording operations and a second dot formation range where dots are to be formed in a subsequent recording operation of the two consecutive recording operations, the apparatus sets, as a correction portion, an end portion in a scanning direction of a specific region including at least one of a first boundary region adjacent to the second dot formation range and a second boundary region adjacent to the first dot formation range in the specific image, and forms the dot placed at the correction portion by discharging liquid of a discharge amount smaller than the discharge amount set for a dot element corresponding to the dot from nozzles.

A controller determines whether, in a case where feeding of a subsequent sheet is performed in a first feed condition, a subsequent sheet contacts conveyance rollers during recording on a preceding sheet, the first feed condition being that feeding of the subsequent sheet is started at a first timing before recording on the preceding sheet ends and that the subsequent sheet is fed at a first velocity, and in response to determining that the subsequent sheet contacts the conveyance rollers during recording on the preceding sheet, controls the feed roller to perform feeding of the subsequent sheet in a second feed condition or a third feed condition, the second feed condition being that the feeding of the subsequent sheet is started at a second timing later than the first timing, the third feed condition being that the subsequent sheet is fed at a second velocity lower than the first velocity.

Control device and storage medium

An image recording apparatus includes a roller pair for transporting a sheet, a recording head, and a controller. The controller determines a linefeed amount by which the sheet is transported by the roller pair between corresponding two adjacent passes of the recording head. The controller executes image recording on the sheet by alternately repeating a linefeed operation for rotating the roller pair by the determined linefeed amount to transport the sheet in a transport direction, and a pass recording operation in which the controller causes the roller pair to stop and the recording head to perform a pass and to record part of an image on the sheet. Upon determining that a linefeed operation would cause the sheet to travel past the roller pair while the roller pair is decelerating, replace for the linefeed operation a determined linefeed amount by an adjusted linefeed amount.

Image recording apparatus and printer driver

A liquid jetting apparatus includes: a conveyance roller; a head; a discharge roller; a tray; a memory; and a controller that receives printing data, drives the conveyance roller and the discharge roller to convey a sheet at a first velocity in a conveyance direction, and controls the head to jet liquid on the sheet. The controller obtains a first amount and a second amount based on the printing data. After the liquid is jetted from the head on the first area, the conveyance roller and the discharge roller are driven to convey the sheet at a second velocity slower than the first velocity and to discharge the sheet on the tray, or conveyance of the sheet is stopped for a predefined time and then the sheet is conveyed at the first velocity to be discharged on the tray.
