Clean the nozzles by purge and wipe
In all three maintenance procedures the nozzles are cleaned by a purge and wipe action. During
the purge actions every nozzle is refilled with new ink. The old ink including any pollution will be
pushed out to the printhead nozzle plate. Next a wiper removes the ink including the nozzle
pollution from the nozzle plate. This results in an optimally cleaned printhead.
Automatic nozzle optimization
In all maintenance procedures you can select the option [Automatic nozzle optimization].
During printing the system uses a mechanism called PAINt, to check if all nozzles are functioning.
If a nozzle is detected as fail, PAINt will compensate this failing nozzle by a good working nozzle.
PAINt can detect the majority of the causes for a failing nozzle during the print.
When you enable [Automatic nozzle optimization] the printer will create a test print on which
each individual nozzle will print a pattern. A camera will scan the printed pattern. If the camera
detects a missing pattern and PAINt did not detect this nozzle as failing, the nozzle will be
switched off permanently. The failing nozzle is compensated by another nozzle for all print jobs,
which results in an optimum print quality.
Use a smooth, white, opaque, non-reflective media when you select Automatic nozzle
optimization.
