Abstract
A printing device includes a print blanket to transfer an ink image onto print media on an impression drum. Responsive to receiving a null cycle trigger during printing, the impression drum is repositioned to a null position to reduce contact between a print blanket and the impression drum.
Claims20
A method, comprising:
- printing a print job;
- during the printing, receiving an interrupt to trigger a null cycle during the printing;
- in response to the receiving the interrupt,
- repositioning an impression drum to a null position to reduce contact between a print blanket and the impression drum;
- and
- in response to detecting that the interrupt has stopped,
- changing a positioning of the impression drum from the null position back to a print position.

A printing device comprising:
- a print blanket to transfer an ink image from a photoreceptor onto print media on an impression (IMP) drum during printing;
- a drum displacer to displace the IMP drum;
- and
- a controller to:
- during the printing, detect an interrupt for a print job being printed by the printing device;
- responsive to the interrupt, cause the drum displacer to displace the IMP drum from having a print width nip level contact with the print blanket to having a null width level contact with the print blanket;
- detect that the interrupt has stopped;
- adjust the IMP drum back to having the print width nip level contact with the print blanket;
- and
- insert a print cycle into the print job.

A non-transitory machine-readable storage medium storing instructions that when executed by a processor, cause the processor to:
- during a print cycle of a printing process detect an interrupt from a printing subsystem;
- and
- in response to detecting the interrupt,
- 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 detecting of the interrupt persists;
- and
- maintain a reduced contact level at a null level between a print blanket and an impression drum during each null cycle.
