Abstract
A printing apparatus capable of feeding standard and non-standard sheets so that image data can be printed on various types of sheets with the need for increasing the number of internal components. One embodiment for achieving this includes a sheet setting unit that permits selection of one of a plurality of predefined sheets, a sheet width sensor unit that senses whether sheets in a sheet supply member meet a predefined width, and a controller coupled to the sheet setting unit and the sheet sensor unit. The controller is responsive to either the selected one of the plurality of predefined sheets or user input of dimensional data of the sheets in the supply member. Based upon the set sheet type or input dimensional data, the controller then adjusts the magnification of the image to be printed and prints the image on the sheets.
Claims13
A printing apparatus capable of using standard and non-standard sheets, comprising:
- a sheet setting unit that permits selection of one of a plurality of predefined sheets;
- a sheet width sensor unit that senses whether sheets in a sheet supply member meet a predefined width;
- and
- a controller coupled to said sheet setting unit and said sheet sensor unit, said controller being responsive to either said selected one of said plurality of predefined sheets or user input of dimensional data of the sheets in said supply member, such that based upon the set sheet type or input dimensional data the controller adjusts the magnification of an image to be printed on the sheets and prints the image on the sheets.
A printing apparatus capable of using irregular sheets, comprising:
- at least one sheet supply member for supplying various sheet types;
- a sheet setting mechanism for setting a type of sheet in the at least one sheet supply member between predefined sheet types and non-defined sheet types;
- and
- a controller electrically coupled to the sheet setting mechanism and an operation unit, and configured to reduce or magnify an image to be printed based on user entered dimensional data of sheets in said sheet supply member if the sheet type is non-defined sheet type.
A printing apparatus capable of using irregular sheets, comprising:
- a sheet cassette for supplying various type sheets;
- a sheet width sensor unit that detects whether a size of sheets in said cassette are smaller than a predefined width and outputs a signal at least when the sheets are smaller than said predefined width;
- a controller electrically coupled to said sheet width sensor unit and responsive to said output signal such that said controller adjusts the magnification of an image to be printed based on dimensional data of the sheets entered by a user using a keyboard if the output signal indicates that the sheets have a width that is smaller than the predefined width.
A printing apparatus capable of using irregular sheets, comprising:
- a sheet cassette capable of supplying various type sheets;
- a sheet width sensor unit that detects whether a size of sheets in said cassette are smaller than a predefined width and outputs a signal at least when the sheets are smaller than said predefined width;
- a display unit that displays a list of sheet types for selection;
- a controller electrically coupled to said sheet width sensor unit and said display unit and configured to adjust the magnification of images to be printed based on a selected sheet type selected by a user from said list, if the sheet width sensor unit outputs a signal that indicates that the sheets have a width that is smaller than the predefined width.
A printing apparatus capable of using standard and non-standard sheets, comprising:
- sheet setting means for permitting selection of one of a plurality of predefined sheets;
- sheet width sensor means for sensing whether sheets in a sheet supply member meet a predefined width;
- and
- controller means coupled to said sheet setting means and said sheet sensor means, said controller means being responsive to either said selected one of said plurality of predefined sheets or user input of dimensional data of the sheets in said supply member, such that based upon the set sheet type or input dimensional data said controller means adjusts the magnification of an image to be printed on the sheets and prints the image on the sheets.
A printing apparatus capable of using irregular sheets, comprising:
- sheet supply means for supplying various sheet types;
- sheet setting means for setting a type of sheet in said sheet supply means between predefined sheet types and non-defined sheet types;
- and
- controller means electrically coupled to the sheet setting means and operation means for reducing or magnifying an image to be printed based on user entered dimensional data of sheets in said sheet supply means if the sheet type is non-defined sheet type.
A printing apparatus capable of using irregular sheets, comprising:
- sheet cassette means for supplying various type sheets;
- sheet width sensor means for detecting whether a size of sheets in said cassette means are smaller than a predefined width and for outputting a signal at least when the sheets are smaller than said predefined width;
- controller means electrically coupled to said sheet width sensor means and responsive to said output signal, for adjusting the magnification of an image to be printed based on dimensional data of the sheets entered by a user if the output signal indicates that the sheets have a width that is smaller than the predefined width.
