Abstract
A printing apparatus is disclosed. The printing apparatus comprises a printhead and a controller. The printhead is to spit a printing fluid comprising a first mode and a second mode. The first mode corresponds to using a first energy level to spit the printing fluid and the second mode corresponds to using a second energy level to spit the printing fluid. The second energy level comprises a higher energy level than the first energy level. The controller is to determine a decap risk zone associated with the printing fluid, determine in view of the decap risk zone a decap location, and instruct the printhead to spit using the second mode at the decap location.
Claims20
A printing apparatus comprising:
- a printhead to spit a printing fluid comprising a first mode and a second mode, wherein the first mode corresponds to using a first energy level to spit the printing fluid and a second mode corresponding to using a second energy level to spit the printing fluid, wherein the second energy level comprises a higher energy level than the first energy level;
- and
- a controller to:
- determine a decap risk zone associated with the printing fluid,
- determine in view of the decap risk zone a decap location, and
- instruct the printhead to spit using the second mode at the decap location.
A method comprising:
- receiving a print job to be printed using a printing composition and a first fire pulse;
- determining a decap risk zone associated with the printing composition based on the print job;
- assign a second fire pulse of the printing composition, wherein the second fire pulse is a higher fire pulse than the first file pulse;
- and
- ejecting an amount of the printing composition on an area associated with the decap risk zone using the second fire pulse.
A non-transitory machine readable medium storing instructions executable by a processor, the medium to receive a print job to be printed using a water-based ink, the non-transitory machine-readable medium comprising:
- instructions to determine a decap risk zone associated with the water-based ink based on the print job;
- instructions to modify a standard printing mode from a printhead in which the water-based ink is to be fired, wherein the modified printing mode comprises a higher energy level than the standard printing mode;
- and
- instructions to control the printhead to fire an amount of the water-based ink on the decap risk zone using the modified printing mode.
