摘要： A printer has monochrome and color printing heads for printing color and monochrome images, respectively, and a media feed path for moving sheets of media by the printing heads. The media feed path has a color position in which the color printing heads print color images and the monochrome printing head prints monochrome images, and a monochrome position in which the monochrome printing head prints monochrome images but the color printing heads cannot print color images. A memory stores data on prior print jobs, and a control circuit switches the media feed path from the color position to the monochrome position in response to the data stored in the memory.

摘要： The amount of toner remaining in each toner cartridge (20a-20d) of a printer (1) is estimated by incrementing a count when one pel is detected in each small region of the bit map. The printer senses toner out, after which the scale ascribed to one count is revised to reflect the actual count to toner out. Specifically, the count to toner out becomes the number representative of empty so that one-half of that count is interpreted as half full. The remaining toner in each cartridge is displayed to the operator at a gauge (21).
