Claim 8

An ejection recovery mechanism for an ink jet apparatus effecting recording using a recording head having a heating device therein and a solid ink which is solid at a temperature below a room temperature and is liquid above a predetermined temperature higher than the room temperature, wherein the recording head is heated by the heating device and ink in the recording head is maintained in a liquid state, the ejection recovery mechanism comprising: a first cleaning member slidable in contact with an ink discharging side surface of the recording head for discharging the liquefied ink to clean the ink discharging side surface; a second cleaning member slidable in contact with said first cleaning member to remove solidified ink from said first cleaning member; a temperature control means for controlling the temperature of said second cleaning member, wherein a temperature of said second cleaning member is controlled at a temperature above the room temperature so as to liquefy the solidified ink on said first cleaning member, and said first cleaning member is thermally independent from said second cleaning member except during contact between said first cleaning member and said second cleaning member; and movement control means for controlling movement of said first cleaning member or said second cleaning member.

Claim 9

A mechanism according to claim 6, wherein the temperature of said second cleaning member is controlled so that said temperature is higher than a melting point of said ink.

Claim 10

A mechanism according to claim 6, wherein said first cleaning member is in a movement path of said recording head, and wherein said first cleaning member is movable and is rubbed by said second cleaning member after said first cleaning member cleans said recording head.

Claim 11

A mechanism according to claim 6, wherein said second cleaning member is disposed adjacent to said recording head and scans with said recording head along a scanning path between a recording region and a non-recording region, and said first cleaning member is disposed in the scanning path and is rubbed by said second cleaning member after said first cleaning member cleans said ink discharging side surface.

Claim 12

A mechanism according to claim 6, further comprising a capping member for capping said recording head, wherein said first cleaning member and said second cleaning member are provided at a portion of contact between said capping member and said recording head.

Claim 13

An ejection recovery method for an ink jet apparatus effecting recording using a recording head having a heating device therein and a solid ink which is solid at a temperature below a room temperature and is liquid above a predetermined temperature higher than the room temperature, wherein the recording head is heated by the heating device and ink in the recording head is maintained in a liquid state, the method comprising the steps of: cleaning an ink discharging side surface of the recording head for discharging the liquefied ink by wiping the surface by a first cleaning member; removing solidified ink from the first cleaning member by wiping said first cleaning member with a second member; controlling a temperature of said second cleaning member at a temperature above the room temperature so as to liquefy the solidified ink on said first cleaning member; removing said ink from the first cleaning member; and operating said first cleaning member thermally independent from said second cleaning member except during contact between said first cleaning member and said second cleaning member.

Claim 14

An ejection recovery method for an ink jet apparatus effecting recording using a recording head having a heating device therein and a solid ink which is solid at a temperature below a room temperature and is liquid above a predetermined temperature higher than the room temperature, wherein the recording head is heated by the heating device and ink in the recording head is maintained in a liquid state, the method comprising the steps of: cleaning an ink discharging side surface of the recording head for discharging the liquefied ink by wiping the surface by a first cleaning member; removing solidified ink from the first cleaning member by wiping said first cleaning member with a second member; controlling a temperature of said second cleaning member at a temperature above the room temperature so as to liquefy the solidified ink on said first cleaning member; removing said ink from the first cleaning member; and operating said first cleaning member thermally independent from said second cleaning member except during contact between said first cleaning member and said second cleaning member.
