Abstract
In an example, a method of controlling voltage applied to a print blanket within a printing device includes printing a print job. During the printing, a null cycle trigger is received. In response to the trigger, contact between a print blanket and an impression drum is reduced.
Claims15
A method of controlling contact between a print blanket and an impression drum, comprising:
- printing a print job;
- during the printing, receiving a null cycle trigger;
- and,
- in response to the trigger, reducing contact between a print blanket and an impression drum.
1 more element
A printing device comprising:
- a print blanket to transfer an ink image onto print media on an impression (IMP) drum during printing;
- a drum displacer to displace the IMP drum;
- and
- a controller to receive a null cycle trigger, and in response to the trigger, to cause the drum displacer to move the IMP drum away from the print blanket during the null cycle.
1 more element
A non-transitory machine-readable storage medium storing instructions that when executed by a processor of a printing device, cause the printing device to:
- during a print cycle of a printing process, detect an interrupt from a printing subsystem;
- in response to detecting the interrupt,
- reduce contact between a print blanket and an impression drum from a print level to a null level;
- and
- insert a first null cycle into the printing process following the print cycle;
- insert an additional null cycle following the first null cycle for each null cycle in which the detection of the interrupt persists;
- and
- maintain the reduced contact between the print blanket and the impression drum during each null cycle.
