When an abnormality such as interferes with execution of the job occurs, data indicative of avoidance countermeasures for each user or each type of abnormality stored in a memory is referred to and the plural avoidance countermeasures are displayed sequentially from the one that is most frequently executed, and an optimum one is selected. After that, the frequency data for the selected avoidance countermeasure is renewed.

Abstract: In a method and apparatus for conversion of color values of a color negative according to a positive/negative reversal function [Rp, Gp, Bp=f(Rn, Gn, Bn)] color values (Rn, Gn, Bn) for the three color components are acquired by optoelectronic scanning of a color negative in a color scanner. The image luminance value (BLr, BLg, BLb) and the image depth value (BTr, BTg, BTb) of the color negative as well as the corresponding density ranges (&Dgr;Dr, &Dgr;Dg, &Dgr;Db) are determined from the color values (Rn, Gn, Bn) in an image analysis unit for each color component. The positive/negative reversal function is determined in a calculating stage from the density ranges (&Dgr;Dr, &Dgr;Dg, &Dgr;Db) and a defined density range (&Dgr;D′). The positive/negative reversal function is deposited in a table memory as a value table. The color values (Rn, Gn, Bn) of the color negative are then converted into the color values (Rp, Gp, Bp) of the corresponding color positive with the stored value table.

Abstract: When the received mail is determined to be print mail in S981 based on its mail header, the program first determines in S982 what page description language is used to describe the print data in the mail. In S983, the program selects a printer which is being presently set to interpret that page description language. Then, in S1040, print data in the print mail is printed using the printer thus selected in S983. If there exists no printer appropriately set to interpret that page description language, the program selects in S983 a printer provided with a function to interpret that page description language. The program then sets the function mode of the printer into a mode to interpret the page description language. Then, in S1040, print data in the print mail is printed using the thus selected and set printer. Thus, the print mail is printed by a printer which can appropriately interpret the processing format of the print data included in the received print mail.

Abstract: In order to prevent an operational amount of color conversion from increasing when resolution is changed since the operational amount of color conversion is increased when the conversion is performed such that resolution is enhanced in printing, resolution of color image data constituting pre conversion data is compared with resolution of color image data constituting post conversion data. As a result of comparison, when the resolution on the input side is lower, color conversion is previously performed and resolution is converted subsequently, when the resolution on the input side is higher, resolution is converted prior to color conversion. Thus where conversion of resolution and color conversion are executed, color conversion is performed on the side having a lower one of the resolutions whereby color conversion is performed in respect of fewer pixels and the processing can be optimized.
