Abstract
Methods and devices provide an electrostatically chargeable surface within a printing apparatus and cause a movable lubricant applicator to contact the electrostatically chargeable surface. The movable lubricant applicator is movable to be in contact with the electrostatically chargeable surface, or out of contact with the electrostatically chargeable surface. Such methods control the movable lubricant applicator to be in intermittent contact with the electrostatically chargeable surface during printing operations of the printing apparatus.
Claims24
A printing apparatus comprising:
- an electrostatically chargeable surface;
- a movable lubricant applicator contacting said electrostatically chargeable surface;
- and
- a controller operatively connected to said movable lubricant applicator,
- said movable lubricant applicator being movable to be one of:
- in contact with said electrostatically chargeable surface;
- and out of contact with said electrostatically chargeable surface under control of said controller, and
- said controller controlling said movable lubricant applicator to be in intermittent contact with said electrostatically chargeable surface during printing operations of said printing apparatus.
A printing apparatus comprising:
- a photoreceptor;
- a movable lubricant applicator contacting said photoreceptor;
- and
- a controller operatively connected to said movable lubricant applicator,
- said movable lubricant applicator being movable to be one of:
- in contact with said photoreceptor;
- and out of contact with said photoreceptor under control of said controller, and
- said controller controlling said movable lubricant applicator to be in intermittent contact with said photoreceptor during printing operations of said printing apparatus.
A method comprising:
- providing an electrostatically chargeable surface within a printing apparatus;
- causing a movable lubricant applicator to contact said electrostatically chargeable surface, said movable lubricant applicator being movable to be one of:
- in contact with said electrostatically chargeable surface;
- and out of contact with said electrostatically chargeable surface;
- and
- controlling said movable lubricant applicator to be in intermittent contact with said electrostatically chargeable surface during printing operations of said printing apparatus.
A method comprising:
- beginning printing operations within a printing apparatus;
- causing a movable lubricant applicator to contact a photoreceptor within said printing apparatus, said movable lubricant applicator being movable to be one of:
- in contact with said photoreceptor;
- and out of contact with said photoreceptor under control of a controller within said printing apparatus;
- and
- controlling, under control of said controller, said movable lubricant applicator to be in intermittent contact with said photoreceptor during said printing operations of said printing apparatus.
