摘要： To achieve high-quality printing by controlling an ink-travelling direction by an electrostatic force so that the ink can be accurately applied on a printing medium, the ink is landed on a desired position of the printing medium effectively without disturbing the ink ejection, independent of a difference in the thickness of the printing medium. An electric field between a printing head and the printing medium is generated by applying a voltage to a platen of conductive material positioned immediately below the printing medium. At this point, the voltage applied to the platen is adjusted so that the electric field of a preferable intensity can be generated on a face of the printing head where ejection openings are formed irrespective of the thickness of the printing medium.

摘要： To achieve high-quality printing by controlling an ink-traveling direction by an electrostatic force so that the ink can be accurately applied on a printing medium, the ink ejected to areas outside edges of the printing medium is prevented from being attracted to the end portions in margin-less printing. This configuration includes: a platen, made of a conductive material, positioned immediately below the printing medium; an absorber positioned at a side of the edge; and a mesh conductive member disposed on the absorber. A first voltage is applied to the platen, causing polarization in the printing medium, and a second voltage higher than the first voltage is applied to the conductive member. Thereby, ink ejected outside the edges in the margin-less printing, travels straight-forwardly toward the conductive member without being attracted to the end portions, and is absorbed into the absorber via the conductive member.

摘要： When the head temperature Tfinish, which is the head temperature at the time of completion of a preceding scan, is higher than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value ΔT lower than the head temperature Tfinish. On the other hand, when Tfinish, the head temperature at the time of print completion, is lower than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value ΔT higher than the head temperature Tfinish. Because of this it is possible to inhibit head temperature rise in the case where an image with a high print density is printed.

摘要： An ink jet recording apparatus includes a recording head having a plurality of discharge ports for discharging ink supplied from an ink tank and a plurality of heating elements. The ink jet recording apparatus further includes a detection unit configured to detect a remaining amount of ink in the ink tank, and a preliminary discharge unit configured to discharge ink from the discharge ports, unrelated to recording, by applying energy to the heating elements for recovering the recording head. The ink jet recording apparatus performs control so that when the remaining amount of ink detected is less than a predesignated remaining amount of ink, energy applied to the heating elements per unit time by the preliminary discharge unit is smaller as compared with energy applied to the heating elements per unit time when the remaining amount of ink is more than or equal to the predesignated remaining amount of ink.
