    • A printing apparatus has a plurality of image forming sections that are removably attached to a body of the printing apparatus and form images of different colors. The apparatus includes a specifying unit such as an operation panel and a control unit. The specifying unit specifies an image forming section that performs printing. The control unit controls the image forming section specified by the specifying unit to form an image of a corresponding color. The apparatus further includes a plurality of detectors that detect the presence and absence of corresponding image forming sections in the body. When the detector detects that a specified image forming section is present, the control unit controls the specified image forming section to operate. When the detector detects that the specified image forming section specified is absent, the control unit does not control the specified image forming section to operate.
    • 打印设备具有多个图像形成部分,其可移除地附接到打印设备的主体并且形成不同颜色的图像。 该装置包括诸如操作面板和控制单元的指定单元。 指定单元指定执行打印的图像形成部。 控制单元控制由指定单元指定的图像形成部分以形成相应颜色的图像。 该装置还包括多个检测器,其检测身体中相应的图像形成部分的存在和不存在。 当检测器检测到指定的图像形成部分存在时,控制单元控制指定的图像形成部分进行操作。 当检测器检测到指定的图像形成部分不存在时,控制单元不控制指定的图像形成部分进行操作。

    • A color image printing apparatus has a plurality of positioning mechanisms each of which selectively positions a corresponding photoconductive drum at an operative position and a non-operative position. A controlling section selectively controls the positioning mechanisms in a first operation mode or in a second operation mode according to the color detected in the color plane by the color detecting section. The first operation mode is a mode where the controlling section causes a positioning mechanism corresponding to the color detected by the color detecting section to the operative position, and the positioning mechanism remains at the operative position throughout the job once it is brought to the operative position. The second operation mode is a mode where if only black is detected in the first page of a job then a photoconductive drum corresponding to black is brought to the operative position, and if any one of yellow, magenta, and cyan black is detected in a subsequent page, the controlling section causes all of the positioning mechanisms to be brought to their operative positions.
    • 彩色图像打印设备具有多个定位机构,每个位置选择性地将相应的感光鼓定位在操作位置和非操作位置。 控制部分根据颜色检测部分在彩色平面中检测到的颜色,在第一操作模式或第二操作模式中选择性地控制定位机构。 第一操作模式是这样的模式,其中控制部分使得与由颜色检测部分检测到的颜色相对应的定位机构到达操作位置,并且定位机构一旦到达操作位置就保持在整个作业位置的操作位置 。 第二操作模式是如果在作业的第一页中仅检测到黑色的模式,则与黑色对应的感光鼓被带到操作位置,并且如果检测到黄色,品红色和青色中的任何一种 随后的页面中,控制部分使得所有的定位机构都被带到其操作位置。
