A printing apparatus that includes printing element substrates which are provided with printing elements that discharge ink. A plurality of temperature sensors, each of which is provided with one of the printing element substrates, measures a temperature of a corresponding printing element substrate. A selection unit selects any one of the temperature sensors, and a determination unit performs a determination operation to determine a state of the printing element substrate based on the temperature measured by the selected temperature sensor in a case when only the printing elements of a substrate that corresponds to the selected temperature sensor are driven. The determination unit performs the determination operation on a first substrate and then on a second non-adjacent substrate.

An ink-jet recording device is capable of correcting a recording position due to a leaning of a printing head and correcting of driving timing between multiple printing heads. Each nozzle row of a printing head is classified into multiple nozzle groups, and the driving timing of the nozzle groups other than the nozzle group serving as a reference of correction of the multiple nozzle groups is adjustable to correct for any leaning of the printing head. Moreover, in the event of performing the driving timing between printing heads, the driving timing of a non-reference printing head is adjustable relative to a reference printing head employed for leaning correction of multiple printing heads.

The present invention provides a liquid ejection head which includes a plurality of ejection ports 302 arranged so as to form an ejection port row and which, after a recovery process of expanding and transferring a bubble toward an ink supply port, allows the bubble to be smoothly removed from a nozzle 310. electrothermal transducing elementA plurality of nozzle filters 306 are arranged between an ink supply port and the ink channel 304 so that ink supplied to the bubbling chamber 303 through the ink supply port is passed between the nozzle filters 306 to separate impurities contained in the ink, from the ink. When a distance between an ink channel inlet 311 and the nozzle filter 306 is defined as L1 and a distance between the adjacent nozzle filters 306 is defined as L2, a relationship between L1 and L2 satisfies L1≦L2.

摘要:
A recording device drives a recording head mounted on a carriage while main-scanning by moving the carriage in a direction generally orthogonal to the sheet-feeding direction of a sheet. The recording device drives a first nozzle of the recording head at an upstream side in the sheet-feeding direction of the sheet to form a first dot pattern while scanning the carriage and drives a second nozzle at a downstream side in the sheet-feeding direction of the sheet to form a second dot pattern. The recording device feeds a region where the first dot pattern is recorded to a position facing the second nozzle. The second dot pattern is recorded in a region where the first dot pattern is not recorded.
