In a control device, a controller is configured to perform: executing a first print printing a first partial image in a first printing area and a second print printing a second partial image in a second printing area; setting a first ink pressure value for the first print; obtaining a recovery value to be recovered in a time period from completion of the first print to start of the second print; calculating a residual pressure value based on the first ink pressure value and the recovery value; setting a second ink pressure value for the second print using the residual pressure value; and determining whether the second ink pressure value reaches a threshold value. A first mode of print is performed when the second ink pressure value does not reach the threshold value. A second mode of print is performed when the second ink pressure value reaches the threshold value.

This application claims priority from Japanese Patent Application No. 2018-248617 filed Dec. 28, 2018. The entire content of the priority application is incorporated herein by reference.
The present disclosure relates to a control device for controlling a printer provided with a head into which ink stored in receptacles is supplied via channels, and a set of program instructions executed on the control device.
An inkjet printer known in the art is provided with: ink cartridges; ink supply tubes connected to the ink cartridges; a carriage unit connected to the ink supply tubes; and a control device. The carriage unit is provided with: buffer tanks connected to the ink supply tubes; an ejecting head having inflow ports into which ink flows from the buffer tanks; and pressure sensors that detect the pressure of ink in the inflow ports. The ejecting head has: channels in communication with the inflow ports; nozzles in communication with the channels; and piezoelectric-driven actuators that eject ink from the nozzles.
The particular features and advantages of the disclosure as well as other objects will become apparent from the following description taken in connection with the accompanying drawings, in which:
FIG. 1A is a perspective view of a printer according to one embodiment in which a cover is at a closed position;
FIG. 1B is a perspective view of the printer according to the embodiment in which the cover is at an open position;
Hereinafter, an embodiment of the present disclosure will be described with reference to the accompanying drawings. The embodiment described below is merely an example of the present disclosure, and it would be apparent to those skilled in the art that the embodiment of the present disclosure may be modified as appropriate without departing from the spirit of the disclosure. For example, the order for executing steps in the processes described below may be modified as needed without departing from the spirit of the disclosure.
FIGS. 1A and 1B illustrate a printer 10. The printer 10 prints images on sheets 6 (see FIG. 2) as an example of the printing medium by ejecting ink onto the sheets 6. That is, the printer 10 is referred to as an inkjet printer.
While printing images on sheets 6, the printer 10 also moves a head 62 (see FIG. 2) that ejects ink. Hence, the printer 10 is also known as a serial printer.
