Abstract
System, method, and software for determining flushing quality in an image forming apparatus. In an embodiment, a flushing quality manager is configured to perform at least one flushing quality check regarding a flushing operation of nozzles in at least one printhead according to a flushing setting of variable flushing settings. The at least one flushing quality check comprises monitoring nozzle defects in the nozzles in jetting of a print liquid, and automatically adjusting the flushing setting when a degree of the nozzle defects exceeds a threshold.
Claims20
An apparatus, comprising:
- a flushing quality manager comprising at least one processor and memory;
- the at least one processor configured to cause the flushing quality manager at least to:
- perform at least one flushing quality check regarding a flushing operation of nozzles in at least one printhead according to a flushing setting of variable flushing settings, the at least one flushing quality check comprising:
- monitoring nozzle defects in the nozzles in jetting of a print liquid;
- and
- automatically adjusting the flushing setting when a degree of the nozzle defects exceeds a first threshold.
A method comprising:
- performing at least one flushing quality check regarding a flushing operation of nozzles in at least one printhead according to a flushing setting of variable flushing settings, the performing comprising:
- monitoring nozzle defects in the nozzles in jetting of a print liquid;
- and
- automatically adjusting the flushing setting when a degree of the nozzle defects exceeds a first threshold.
