A printing apparatus counts an ink quantity in an ink tank in accordance with consumption of ink from the ink tank, updates and holds a count value obtained by the count in a counter, and detects whether ink injection to the ink tank has been done before execution of sensing by a sensing unit configured to sense whether a predetermined quantity of ink is present in the ink tank. If sensing by the sensing unit is executed, the apparatus reads out a preceding sensing result from a memory that stores a sensing result of presence/absence of the ink by the sensing unit, verifies a transition between the preceding sensing result and a current sensing result, and controls operations of reset of the count value held by the counter and the count based on the transition and a result of the detection.

Ejection apparatus and wiping method

An ejection apparatus includes an ejection head having an ejection port surface and configured to eject a liquid to a recording medium for recording, a wiper configured to wipe the surface, and a moving unit configured to relatively move the wiper and the head to move the wiper in a first direction along the surface with respect to the head. The apparatus performs a first mode for performing the wiping while relatively moving the wiper and the head at a first speed, and a second mode for performing the wiping while relatively moving the wiper and the head at a second speed higher than the first speed. When the apparatus performs the wiping after the recording and then performs subsequent recording, the apparatus performs the second mode. When the apparatus performs the wiping after the recording and then performs no subsequent recording, the apparatus performs the first mode.

There is provided a printing apparatus. A cap caps an ink ejection surface of a printhead. An ink suction path is connected to the cap and sucks the ink in the cap. An ink tank stores the ink to be supplied to the printhead. An ink supply path connects the printhead to the ink tank. A first closing unit closes the ink suction path. A second closing unit closes the ink supply path. A control unit is able to execute a first control mode in which the first closing unit closes the ink suction path and a second control mode in which the second closing unit closes the ink supply path.

When the head temperature Tfinish, which is the head temperature at the time of completion of a preceding scan, is higher than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value &#x394;T lower than the head temperature Tfinish. On the other hand, when Tfinish, the head temperature at the time of print completion, is lower than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value &#x394;T higher than the head temperature Tfinish. Because of this it is possible to inhibit head temperature rise in the case where an image with a high print density is printed.

In a case in which a cumulative value &#x3a3;Nure of wetting coefficients is less than a wetting threshold value THNure, printing is carried out on a unit area through a print mode in which an image is completed through a first number of instances of a scan, and in a case in which the cumulative value &#x3a3;Nure is equal to or greater than the wetting threshold value THNure, printing is carried out on a unit area through a print mode in which an image is completed through a second number of instances of the scan, where the second number is greater than the first number.

Printing apparatus and printing method

A recording apparatus to record an image to a recording medium includes a recording head having nozzles arranged in a predetermined direction in a nozzle array, scanning, recording control, obtaining, determining, and adjusting units. The scanning unit scans the recording head to the recording medium in a crossing direction. The recording control unit causes the recording head to record an adjusting pattern and a detecting pattern by discharging ink from a nozzle group. The obtaining unit obtains an information regarding number of defective discharge nozzles in the nozzle group based on the detecting pattern. The determining unit determines an adjusting value based on the recorded adjusting pattern where the indicated number is smaller than a threshold value, and not based on the adjusting pattern where the indicated number is larger than the threshold value. The adjusting unit adjusts the recording head recording position based on the determined adjusting value.

The scaling process unit scales an image to be formed on the printing medium in accordance with a detected size when a size of a printing medium indicated by size setting information and the detected size do not match each other. The preliminary discharge unit causes the printhead to perform preliminary discharge in accordance with a scaling result of the scaling process unit.

Printing apparatus and control method

In an ink jet printing apparatus and control method using a plurality of parts of a printing unit, ink ejection can be immediately started. First and second heating units heat first and second parts of the printing unit. Each of the first and second heating units performs heating when the temperature of each of the first and second parts of the printing unit is lower than a reference temperature, and stops heating when the temperature of each of the first and second parts of the printing unit is at least equal to the reference temperature. A control unit controls ejecting of ink from the printing unit such that the printing unit starts ejecting ink according to both first and second information, the first and second information indicating that the temperature of the first and second parts of the printing unit once reached the reference temperature under certain circumstances.

If a completion temperature acquired by the acquisition unit at a time when a previous print scan is completed is lower than a threshold temperature, the setting unit sets a temperature higher than the completion temperature as the target temperature, and if the completion temperature is equal to or higher than the threshold temperature, the setting unit sets a temperature lower than the completion temperature as the target temperature.
