    摘要: A motion-absorbing region is formed in a continuous form, and a passively rotatable fixing roller is moved into contact with the continuous form when the motion-absorbing region is formed. The motion-absorbing region absorbs the difference in relative speed between the fixing roller and the continuous form, keeping the difference or delay from being transmitted along the form to the region where a toner image is applied to the form. The electrophotographic transfer of the image to the continuous form is started before the pressure roller is moved into contact with the continuous form. The motion-absorbing region can be a slack region formed by feeding the form while the form is not under tension, or a resilient region formed by applying a resilient biasing device to the form while the form is under tension.

    摘要: A sheet feed mechanism for an electrophotographic printer employing continuous fan-fold paper may be controlled between multiple operational modes. Following image formation on each page, the sheet feed may be stopped or advanced and then stopped. A desired mode is selected depending on whether the user desires to print more than one page successively or to separate printed pages. The sheet feed mechanism ensures that the printer does not needlessly advance the continuous sheet when there are pauses in data transmission or other pauses.

    摘要: In an electrophotographic imaging apparatus, an imaging operation, to form an image on a continuous recording sheet, is executed. First, an unfixed toner image is transferred on the recording sheet, and fixed by a pair of fixing rollers, while the imaging operation is executed, the continuous sheet is fed. If all of the transferred images, i.e., unfixed images have been fixed, the fixing operation is stopped, and at least one of the fixing rollers is retracted.
