Maintenance Item
This function is used to execute Cleaning efficiently when ink is not
delivered from the Head properly, e.g. dot missing.
Head cleaning
The printer causes a maintenance error when the maintenance counter
(for the Waste Ink Tray, Waste Ink Pad Lower) reaches its maximum.
Use this to reset the counter after replacing the Waste Ink Pad and Waste
Ink Pad Lower, and use this to reset the ink tube counter when replacing
Maintenance counter
the Ink Supply Tube. 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.
This function is used to charge ink to the components composing the ink
path such as Printhead after replacing them.
Ink charge
When an ink out error occurs even though some ink is still in the Ink
Supply Tank Assy (in the case when the ink counter in the printer and the
Small ink counter reset actual ink remaining amount do not match), this function can decrease
the ink counter (resetting the counter partially) to adjust the counter with
the actual ink remaining amount.
