摘要： To reduce a quantity of uselessly consumed ink when an ink jet head is recoverably activated, the capacity of an ink path communicated with a group of ejecting ports having a small flow rate coefficient is determined to be smaller than that of an ink path communicated with a group of ejecting ports having a large flow rate coefficient. While all of plural groups of, ejecting ports are fully covered with a common recovering cap with the aid of sucking means, ink is, sucked from the plural groups of ejecting ports. When the ink remaining in the region extending from the plural groups of ejecting ports to predetermined positions in a plurality of ink paths communicated with the plural groups of ejecting ports is discharged, ink discharging positions are dislocated to predetermined positions in a plurality of ink paths to positionally coincide with the predetermined positions in the substantially same timing relationship after ejection recovering treatment starts to be conducted.

摘要： A cleaning method for an ink jet recording apparatus includes a first cleaning step and a second cleaning step. In the first cleaning step, an ink discharge port surface of the apparatus is cleaned in accordance with a degree of reflection of the surface, where the reflection rate is detected by an optical sensor included in the recording apparatus. In the second cleaning step, a cleaning of the surface which is different from the first cleaning is performed in accordance with an output of the optical sensor.
