An original-feeding device includes an original tray, a pickup roller configured to be lowered onto originals stacked on the tray and to feed one of the originals, the pickup roller configured to be lifted up after the feeding, a conveyor configured to convey the fed original, a length detector configured to detect a length of the conveyed original, an original sensor configured to detect a trailing edge of the conveyed original, and a controller configured to control the pickup roller either in a first mode in which the pickup roller is lowered in accordance with a detected length of the original or in a second mode in which the pickup roller is lowered at the detection of a trailing edge of the original. The controller changes the first mode to the second mode if lengths of the originals detected by the length detector vary.

A document feeding apparatus includes a document tray configured to receive a document placed thereon and to move up and down, a start key configured to issue a command to start a process accompanied by a document feeding of the feeding unit, and an operation key configured to be used to set a condition for the process. The document feeding apparatus is operable in a first mode or second mode, wherein the first mode the document tray is raised in response to an operation of the start key and in the second mode, the document tray is raised in response to an operation of the operation key.

Prior to reading an original image, whether to read the original image in a monochrome image mode in which the image reading apparatus reads the original image in use of the monochrome line sensor or a multi color image mode in which the image reading apparatus reads the original image in use of the multi color line sensor is predicted. Preparation of reading an original image based on parameters corresponding to the predicted mode is completed before the start of reading the original image. This arrangement reduces a time loss arising from switching of a color mode associated with a user color setting at the start of a job, and thus shortens the FCOT. This arrangement can shorten the time until the first copy is output after designating the start of copying when reading an original image based on different parameters.

In reading an image of a document in a monochromatic document reading mode, a document reading apparatus reads the image of the document while conveying the document at a speed determined according to a variable magnification ratio, executes digital variable magnification on the read multivalued image in a main scanning direction by using a main scanning direction variable magnification unit, binarizes the multivalued image, and stores the binary image on a memory. In reading an image in a color document reading mode, the document reading apparatus reads the image of the document while conveying the document at a predetermined speed, stores the read multivalued image on the memory, and executes digital variable magnification on the multivalued image in the main scanning direction and a sub scanning direction.

The present invention provides a liquid application device and an inkjet recording apparatus, which are capable of supplying liquid to a liquid room with the power consumption and/or the noise which are reduced. A pump is driven to fill a liquid retention space S with an application liquid. When the filling has been completed, the pump is stopped. Subsequently, the application liquid is applied to an application medium which has been transferred. At this time, a count in a RAM is increased. Thereafter, the determination as to whether or not the application can be carried out is made on the basis of the count and the prescribed application-performable number of sheets stored in a ROM. If it is determined that the application cannot be carried out, the filling of the application liquid is performed. If it is determined that the application can be carried out, next application is performed.
摘要:
An adjustment value applicable to the adjustment of a printing position is obtainable by reading a printing position adjustment pattern printed on a printing medium without requiring the manual operation by the operator. Furthermore, the printing position can be optimally adjusted by accurately scanning the printing position adjustment pattern. For this purpose, an optical sensor is located in the vicinity of the printing head, and the optical sensor is situated near a predetermined position side. The predetermined position side is a pinch roller side where a large restrictive force acts to the printing medium with the printing position adjustment pattern printed thereon.

If print agents used are detected by an optical sensor at different sensitivities, the present invention enables the easy setting of adjustment values for print positions resulting from these print agents. To accomplish this object, for example, the present invention substitutes and sets adjustment values for print positions resulting from cyan, light cyan, or black ink, corresponding to a high detection sensitivity, for adjustment values for print positions resulting from a light magenta, yellow, or magenta ink, corresponding to a low detection sensitivity.

The present invention provides an ink jet printing apparatus and a method for controlling an ink jet printing apparatus which can shorten the stirring duration without losing any stirring effect by stirring ink at a required time to only a required level and still perform a printing operation with no image impairments. By a reciprocal movement of the carriage according to a mode during a non-printing operation excluding a print operation that is accompanied by a reciprocal movement of the carriage, ink in an ink tank is stirred. The stir mode is set according to the color of the ink in the ink tank mounted on the carriage.

For a serial color ink jet printing apparatus that forms an image using a symmetric printing head that ejects large dots and small dots, the configuration of a printing head is provided for suppressing, to the extent possible, a cyclic fluctuation in the main scanning direction. According to the present invention, individual nozzle arrays are arranged so that two nozzle arrays, i.e., a cyan nozzle array c1 and a magenta nozzle array m1, that are located nearer each other, form dots on adjacent scan lines. With this arrangement, a high quality image, having neither an uneven density nor an uneven color, can be formed when a printing head is inclined, or when a cyclic shift in printing positions occurs, depending on the position of the main scanning direction.
