Abstract: When a user enters control information for controlling a printing device, the information is stored in a user information storage unit. All combinations of items of the control information capable of being set by the user and values of items incapable of being set by the user, these having been selected so as to be the optimum values for the combinations, are stored as preset values in a combined information storage unit. An information storage unit compares a value in the user information storage unit with a value in the combined information storage unit. If a combination for which agreement is achieved is found in the combined information storage unit, this value is stored in a printing information storage unit and transmitted to the printing device. Thus, an optimum value can be selected and sent to the printing device even with regard to an item incapable of being selected by the user.

Abstract: What is provided herein is a novel system and method for estimating the amount of color in a document. In one embodiment, a binary CMYK input image is received. Each of the CMYK plane is received at an offset from the previous plane, i.e., the 4 planes are not received simultaneously. Each plane is divided into M×N tiles. Pixel values of all four planes are examined separately and the number of on-pixels is counted for each plane. The number of on-pixel counts for each tile are aggregated for each plane. Total on-pixel counts are used to estimate the total number of white, black, color, and gray pixel counts. The total counts for all planes are used to estimate the amount of color. A document is determined to be color if the amount of color exceeds a predetermined threshold. A color billing strategy is determined based on the estimated color amount.

Abstract: What is provided are a novel system, method, and computer program product for estimating the amount of color in a document to be printed, with the capability to handle composite black. A color billing strategy can be dynamically determined based on the amount of color in the document. In one embodiment, a contone CMYK image is examined and the level of color is estimated based on information extracted from the four planes simultaneously. More specifically, it examines the pixel values from all the four planes to calculate the number of white, black, color, and gray or neutral pixel counts. Input CMYK values can be pre-adjusted via a look-up table to take into account neutral balance characteristics. The difference among the adjusted color values is compared against a threshold that is input level dependent. Color is further subdivided into fuzzy colors to handle highlights and neutral areas.

Abstract: When an original document is placed on the lift tray, a timer is reset and starts counting a predetermined time. Whether an alignment device is moved to adjust the original documents loaded on the lift tray in, for example, the widthwise direction transverse to the transportation direction is then determined.

If there is no change in the detected width of the original documents, a control waits for the timer to time out. If the timer reaches the predetermined time, the lift tray is driven up by the lift motor and rises until the top limit sensor turns on.
