Head cleaning This function is used to execute cleaning efficiently when ink is not
delivered from the head properly, e.g. dot missing.
The head cleaning is performed automatically. After the cleaning, print a
nozzle check pattern to check if all nozzles are firing ink properly.
• Adjustment Program
Waste ink pad counter The printer causes a maintenance error when the waste ink pad counter
reaches its maximum. Use this to reset the counter after replacing the
Waste Ink Pad. If you find the counter is close to the maximum during
servicing, carry out the pad replacement and the counter reset to avoid
the printer returned from the user due to the maintenance error.
After replacing the Waste Ink Pad, reset the counter to its default.
• Adjustment Program
Ink charge This must be carried out after replacing the printhead in order to fill ink
inside the new printhead. The printhead becomes ready for print.
Filling ink inside the printhead is automatically performed. Print a
nozzle check pattern to check if all nozzles are firing ink properly.
