Abstract
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.
