Abstract
A recording apparatus includes a recording unit; a wiping unit configured to wipe the discharge port surface; at least one memory storing instructions; and at least one processor that is in communication with the at least one memory and that, when executing the instructions, cooperates with the at least one memory to perform control to cause the wiping unit to perform a wiping operation for wiping the discharge port surface, and then cause the wiping unit to feed the wiping member to enable wiping with a new region of the wiping member in a next wiping operation, acquire information about a discharge amount for each discharge port array, and determine a feed amount for feeding the wiping member after the wiping operation, based on the information about the discharge amount.
Claims20
A recording apparatus comprising:
- a recording unit having a discharge port surface having a plurality of discharge port arrays each including a plurality of discharge ports for discharging ink;
- a wiping unit including a sheet-like wiping member for wiping the discharge port surface, and configured to wipe the discharge port surface;
- at least one memory storing instructions;
- and
- at least one processor that is in communication with the at least one memory and that, when executing the instructions, cooperates with the at least one memory to
- perform control to relatively move the wiping unit and the recording unit in an arrangement direction of the discharge port arrays, cause the wiping unit to perform a wiping operation for wiping the discharge port surface, and then cause the wiping unit to feed the wiping member to enable wiping with a new region of the wiping member in a next wiping operation,
- acquire information about a discharge amount for each discharge port array, and
- determine a feed amount for feeding the wiping member after the wiping operation, based on the information about the discharge amount.
A wiping method comprising:
- wiping in which a recording unit, having a discharge port surface having a plurality of discharge port arrays each including a plurality of discharge ports for discharging ink, and a wiping unit, provided with a sheet-like wiping member for wiping the discharge port surface and configured to wipe the discharge port surface, are relatively moved in an arrangement direction of the discharge port arrays and the wiping unit is caused to perform a wiping operation for wiping the discharge port surface;
- performing, after the wiping, feeding by controlling the wiping unit to feed the wiping member to enable wiping with a new region of the wiping member in a next wiping operation;
- acquiring information about a discharge amount for each discharge port array;
- and
- determining a feed amount for feeding the wiping member after the wiping operation based on the information about the discharge amount acquired in the acquiring,
- wherein, in the feeding, the wiping member is fed by the feed amount determined in the determining.
