Abstract
A method of operating an electrophotographic printer (100) to control the optical density of a printed image is described. The method comprises providing a printing substance on a transfer member (104); emitting a pulse of heat to heat the printing substance on the transfer member to increase flowability of the printing substance on the transfer member; and transferring, from the transfer member to a substrate (108), the printing substance heated by the pulse of heat so as to provide the printed image on the substrate.

A method of operating an electrophotographic printer to control the optical density of a printed image, the method comprising:
- providing a printing substance on a transfer member;
- emitting a pulse of heat to heat the printing substance on the transfer member to increase flowability of the printing substance on the transfer member;
- and
- transferring, from the transfer member to a substrate, the printing substance heated by the pulse of heat so as to provide the printed image on the substrate.
An electrophotographic printer comprising:
- a transfer element to transfer an image from the transfer element to a substrate;
- and
- a heater to emit a pulse of heating energy to heat the image on the transfer element with a power density of at least 0.1 W/mm2.
An electrophotographic printer to control the optical density of a printed image, the electrophotographic printer being to:
- provide a printing substance on a transfer member;
- emit a pulse of heat to heat the printing substance on the transfer member to increase flowability of the printing substance on the transfer member;
- and
- transfer, from the transfer member to a substrate, the printing substance heated by the pulse of heat so as to provide the printed image on the substrate.
