OPERATING PRINCIPLES Printer Mechanism 34
† Manual Cleaning
This printer provides three different manual cleanings to remove ink coagulated by
air bubbles, viscous material, or foreign matter. Perform the following manual CL
operations by operating the panel or using the utility included in the printer driver.
Independently of the printing path after the previous CL, perform manual CL from
CL1 to CL3 in order if the cumulative printing timer counter is less than 9 minutes.
When the cumulative printing timer counter is more than 9 minutes, only CL1 is
executed.
„ Wiping Operation
Clean the nozzle surface, with the right-half of the rubber part on the wiper.
„ Flushing Operation
Prevent color mixture. Stabilize the ink surface inside the nozzles.
In addition, the printer determines which CL to perform according to the
remaining amount of ink in the Cartridge. When the printer detects the amount is
low, it automatically choose the CL that uses ink less than the other CLs. If the
remaining amount of ink is extremely low (Ink Low or Ink End status), the printer
disables the all the manual cleanings and indicates the status on the STM3.
† Timer Cleaning
Ink is consumed depending on the combination of the cumulative printing timer,
cumulative cleaning count and cleaning timer.
† Flushing
There are two types of flushing.
„ Flushing before printing
This is performed to reduce the viscosity of ink in the Printhead nozzles
before starting to print.
„ Scheduled Flushing
This is performed to prevent ink in the Printhead nozzles from increasing its
viscosity during printing.
