The ink receiver includes a plurality of first ink grooves and a plurality of second ink grooves configured to guide the received ink, the second ink grooves having a tilt angle greater than that of the first ink grooves. The platen includes an absorber configured to absorb the ink received by the ink receiver, the absorber being arranged on a back side of the ink receiver.

Printing apparatus

An object is to provide a liquid ejecting apparatus that enables a liquid storage container to be properly and easily refilled with a liquid from a liquid refilling container without causing color mixture in the liquid storage container. The liquid ejecting apparatus includes liquid storage containers each configured to feed the liquid to a liquid ejecting portion and liquid refilling containers each configured to refill the liquid storage container with the liquid. A first fitting unit is provided around a liquid injection port in each of the liquid storage containers. A second fitting unit is provided around a liquid pour-out port in each of the liquid refilling containers. The second fitting unit is fitted to the first fitting unit to enable the liquid to be delivered from the liquid pour-out port to the liquid injection port.

Liquid ejecting apparatus and liquid refilling container

Provided is a printing apparatus enabling a user to easily perform jam processing. The printing apparatus includes a printing unit, a cassette in which a plurality of sheets to be printed by the printing unit are mounted, and which is capable of being drawn out from the device by a user, a roller pair which is capable of being in an abutting state and a separate state and transports the sheet supplied from the cassette by interposing the sheet, in the abutting state, and a mechanism which changes the roller pair from the abutting state to the separate state as the cassette is drawn out.

A sheet feeding mechanism includes a sheet feeding roller configured to feed an uppermost recording medium from stacked recording mediums, an inclined portion located at a downstream position of the sheet feeding roller in a conveyance direction of the recording medium and having a surface inclined with respect to the conveyance direction, and a restriction member configured not to contact the recording medium before the sheet feeding roller feeds the recording medium, and configured to contact the recording medium in a state where the recording medium is fed by the sheet feeding roller and conveyed along the inclined portion.

Sheet feeding mechanism and recording apparatus having the sheet feeding mechanism

It is an object of the present invention to provide a printing apparatus and a printing method which can perform an appropriate printing operation on a print medium while keeping an ink ejection range to a minimum required even when the print medium transported is deviated from a theoretical position, and which can also reduce a running cost and ink mist. Thus, the present invention is characterized by determining the actual position of the print medium transported to the printing position; based on the determined print medium position, setting an area slightly larger than the print medium lying area as a print area; and performing the printing operation on that area.

Printing apparatus and printing method

The invention is to provide a recording apparatus and a recording method, capable of automatically specifying a type of a recording medium by a simple and inexpensive structure, thereby automating a sheet type setting operation and avoiding an error of user in such sheet type setting operation. The apparatus is equipped with first detectors for detecting a width dimension of a recording medium, a second detector for detecting a surface characteristic of the recording medium, and a discriminator for discriminating the type of the recording medium based on the results of the first and second detectors.

Recording apparatus and recording method

If a plurality of print jobs is received irregularly, this invention makes it possible to perform a proper double-sided printing on a print medium. The printing apparatus of this invention comprises: print medium transport unit; printing means; discharge unit for discharging the print medium from the transport path; and double-sided printing control unit for controlling these unit. When the printing of a last page of print data based on a preceding print command is ended on the first surface of a print medium, the double-sided printing control unit does not discharge the print medium and has the print medium, whose first surface was printed, stand by in the transport path. Then, when the next print command is input, a first page of print data in the next print command is printed on the second surface of the print medium.

Printing apparatus and method for controlling printing apparatus

A recording apparatus having a discriminating unit for discriminating the type of a recording medium loaded on a loading unit. The discriminating unit discriminates the type of a subsequent recording medium responsive to the previous recording medium being fed by a predetermined length during recording of the previous recording medium. The recording apparatus also includes a sensor for detecting the trailing edge of the recording medium. The recording apparatus confirms whether image data for recording on the subsequent recording medium is stored before or after detection of the trailing edge of the previous recording medium.

Recording apparatus and method for discriminating type of recording medium

A recording apparatus has a feed mechanism for feeding a recording medium loaded on a recording-medium loading section; a recording unit for recording on the recording medium fed by the feed mechanism; and a recording-medium discriminating device for discriminating the type of recording medium loaded on the recording-medium loading section. The type of recording medium is discriminated by the recording-medium discriminating device before the feeding operation by the feed mechanism, and the operation of the recording unit is controlled according to the type of recording medium stored in a memory.

Recording apparatus and method for discriminating recording medium type

A feeding device has a loading unit for allowing one of a plurality of recording media and a storage case having a plurality of recording media contained therein to be selectively loaded thereon, a feeding roller for feeding the recording media from the loading unit, and ribs for preventing the storage case from floating to restrict the position of the storage case relative to the feeding roller.

Feeding device with loading device adapted to hold a plurality of media or a storage case with a plurality of media and recording apparatus containing same

The present invention attempts to minimize irregularity in recording caused by a variation in transport of a carriage. One of a plurality of kinds of timing, according to which a recording signal is applied, set relative to a signal indicating the position of the carriage is selected in order to record data.

Recording apparatus and method of controlling recording apparatus

In the case of conducting the printing through the use of a print head having nozzles disposed at a pitch being twice a predetermined pitch Pd of recording dots, control is executed to satisfy the condition that, when a minimum integer 3 forming inter times a value 3 obtained by dividing a feed quantity L corresponding to the minimum drive unit of a drive motor by the predetermined recording dot pitch Pd is divided by an integer 2 obtained by dividing a pitch Ph of the nozzles of the print head by the recording dot pitch Pd, the residue 1 is not a divisor, above 2, of the integer 2 obtained by dividing the print head nozzle pitch Ph by the recording dot pitch Pd. Whereupon, it is possible to increase the recording medium conveying speed and further to realize high-quality recording at a small recording dot pitch.

Recording apparatus and control method thereof

A code printing method and apparatus which prints an image and a code on the same recording medium. The apparatus stores a plurality of density patterns corresponding to each density, and codes corresponding to the density patterns. When code data is inputted and printing of the code is instructed, the apparatus determines the density of each pixel of image data, selects the density pattern representing the code data among the density patterns corresponding to the pixel density, and prints the density pattern instead of the image pixel. Thus, the image and code are printed without deterioration of image quality.
