Estimating the term…
An electrostatographic printer for forming an image onto a web comprises at least one toner image-producing electrostatographic station having a drum onto which a toner image can be formed, a transport for conveying a web past the image-producing station, apparatus for controlling the speed and tension of the web while it is running past the image-producing station, and transfer apparatus for transferring the toner image on the drum onto the web. The printer is characterized by a control arrangement for switching between a printing mode wherein a printing web moves in synchronism with the peripheral speed of the drum and a refurbishment mode wherein a refurbishment web moves at a faster speed relative to the peripheral speed of the drum and in contact therewith, to cause refurbishment of the drum surface.
An electrostatographic printer for forming an image onto an image receiving web, which comprises:
A process of operating an electrostatographic printer wherein a toner image is formed on a rotatable endless surface at an image producing station, a web is conveyed past said image producing station and said toner image is transferred to a printing web at said station, the process being characterized by a printing mode in which a printing web is conveyed in synchronism with said endless surface to receive said toner image, and a refurbishment mode wherein said endless surface is driven at a higher peripheral speed than in said printing mode, wherein a refurbishment web is conveyed past said image producing station in contact with said endless surface and at a relative speed with respect thereto to refurbish said surface.
