Abstract
A method of introducing ink in an ink-jet recording apparatus including an ink-jet printing head which ejects, to a recording medium, the ink through nozzles thereof, the method including the steps of a first ink-introducing step of initially introducing a first ink into the ink-jet printing head when the ink-jet printing head is initially used, the first ink having a first degree of deaeration; and a second ink-introducing step of subsequently introducing a second ink into the ink-jet printing head after the first ink-introducing step, the second ink having a second degree of deaeration, which is lower than the first degree of deaeration.
Claims22
A method of introducing ink in an ink-jet recording apparatus comprising an ink-jet printing head which ejects, to a recording medium, the ink through nozzles thereof, said method comprising the steps of:
- a first ink-introducing step of initially introducing a first ink into said ink-jet printing head when said ink-jet printing head is initially used, said first ink having a first degree of deaeration;
- and
- a second ink-introducing step of subsequently introducing a second ink into said ink-jet printing head after said first ink-introducing step, said second ink having a second degree of deaeration, which is lower than said first degree of deaeration.
An ink-jet recording apparatus comprising an ink-jet printing head having nozzles through which ink is ejected to a recording medium, an ink package in which the ink that is to be introduced into said ink-jet printing head is accommodated, a mounting portion on which said ink package is removably mounted, and an ink-introducing device which introduces, into said ink-jet printing head, the ink that is accommodated in said ink package mounted on said mounting portion, wherein said ink package comprises an initial-use ink package accommodating a first ink having a first degree of deaeration and a replacement ink package accommodating a second ink having a second degree of deaeration which is lower than said first degree of deaeration, said initial-use ink package and said replacement ink package being selectively mounted on said mounting portion, said initial-use ink package being initially mounted on said mounting portion when said ink-jet printing head is initially used.
An ink-package assembly including an ink package accommodating deaerated ink and a sealing wrapper which encloses said ink package and whose interior space is kept in a state that enables said deaerated ink to maintain a degree of deaeration thereof, said ink-package assembly having an indication that said ink package is an initial-use ink package, said initial-use ink package being initially mounted on an ink-jet printing head.
An ink-package assembly including an ink package and a wrapper which encloses said ink package and whose interior space is kept at an atmospheric pressure, wherein said ink package assembly has an indication that said ink package is a replacement ink package, said replacement ink package replacing an ink package which has been mounted on an ink-jet printing head immediately before said replacement ink package is mounted on said ink-jet printing head.
An ink package which is not enclosed in any wrapper and has an indication that said ink package is a replacement ink package, said replacement ink package replacing an ink package which has been mounted on an ink-jet printing head immediately before said replacement ink package is mounted on said ink-jet printing head.
