Abstract
A liquid ejection apparatus includes: a head having ejection-opening groups and ejection-passage groups; caps for covering the respective ejection-openings groups; and suction passages connecting between the interiors of the respective caps and a sucking device. A method of manufacturing the liquid ejection apparatus includes: a step of classifying, as a first group, an ejection-opening group corresponding to an ejection-passage group having a resistance value not less than a first value and classifying, as a second group, another ejection-opening group corresponding to an ejection-passage group having a resistance value less than the first value; and a step of assigning at least one suction passage having a resistance value less than a second value to the ejection-opening group as the first group and assigning another at least one suction passage having a resistance value not less than the second value to the ejection-opening group as the second group.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
