Definitions
- the present invention relates to an inkjet printer. More particularly, the present invention relates to a method of filling ink into an ink path, a method of extracting ink from the ink path, and a method of cleaning the ink path in an inkjet printer.
- the ink jet printer includes an ink supply path (hereinafter simply referred to as “ink path”) that connects an ink cartridge that is an ink supply source and an ink head.
- ink path an ink supply path
- Patent Document 1 discloses an ink jet printer including two ink cartridges, one ink head, and an ink path that connects the ink cartridge and the ink head. According to this ink jet printer, when one ink cartridge becomes empty, ink can be supplied from the other ink cartridge. Therefore, the ink cartridge can be replaced without interrupting printing.
- FIG. 18 is an explanatory diagram of a conventional ink path.
- the ink path 150 includes two tubes 106 and 108 and a tube 118 that connects these tubes 106 and 108.
- One end 106 c of the tube 106 is connected to the ink cartridge 102, and the other end 106 d is connected to the ink head 100.
- One end 108 c of the tube 108 is connected to the ink cartridge 104, and the other end 108 d is connected to the ink head 100.
- the tubes 106 and 108 are provided with valves 112 and 116, respectively.
- an operation of filling the tubes 106, 108, and 118 with ink is performed. Specifically, the valves 112 and 116 are opened, and suction is performed from the lower surface 100a of the ink head 100 by a pump (not shown).
- ink suction varies due to, for example, the arrangement or shape of the tubes 106, 108, 118, more ink may be sucked from the tube that is easier to suck. is there.
- the tube 106 is easier to suck than the tube 108
- the ink sucked from the ink cartridge 102 flows into the upstream region 106a of the tube 106 (FIG. 19A).
- the ink is diverted to the tube 118 and the downstream region 106b at the connection portion P1.
- the ink that has flowed into the tube 118 flows to the downstream region 108b of the tube 108 via the connection portion P2, and then flows to the ink head 100 (FIG. 19B).
- the ink that has flowed to the downstream area 106 b flows to the ink head 100. Thereafter, when the suction by the pump is continued, the ink is sucked little by little from the ink cartridge 104 connected to the tube 108 which is hard to suck. The sucked ink flows to the upstream region 108 a of the tube 108. During this time, ink is continuously sucked from the ink cartridge 102 connected to the tube 106 and is continuously discharged from the ink head 100.
- the conventional ink filling method has a problem that the amount of wasteful ink consumption increases.
- the ink remaining amount of the ink cartridges 102 and 104 is typically determined based on the assumption that the amount of ink discharged from both ink cartridges 102 and 104 is the same during the suction. Calculate based on time. For this reason, for example, when the wasteful ink consumption increases as described above, there is a problem that it is difficult to accurately grasp the remaining amount of ink.
- the ink sucked from the ink cartridge 102 flows in the order of the upstream area 106 a of the tube 106, the connecting portion P 1, and the downstream area 106 b and reaches the ink head 100.
- the ink sucked from the ink cartridge 104 flows in the order of the upstream area 108a of the tube 108, the connecting portion P2, and the downstream area 108b, and reaches the ink head 100.
- a region not filled with ink is formed in the central portion of the tube 118 (FIG. 19C). For this reason, an air layer (bubbles) is generated in the tube 118, and these bubbles may flow into the ink head 100 and cause problems such as printing defects.
- the ink cartridges 102 and 104 when the ink cartridges 102 and 104 are exchanged, an operation of extracting ink from the tubes 106, 108, and 118 is performed. Specifically, after removing the ink cartridges 102 and 104 from the tubes 106 and 108, respectively, the valves 112 and 116 are opened, and the ink in the tubes 106, 108, and 118 is pumped from the lower surface 100a of the ink head 100 (see FIG. (Not shown).
- suction between the tubes 106 and 108 there may be variations in suction between the tubes 106 and 108, and ink may not be completely removed from the tube that is difficult to suck.
- the suction by the pump is started from the state where the tubes 106, 108, 118 are filled with ink. Then, first, the ink in the downstream areas 106 b and 108 b flows into the ink head 100. Next, the ink in the tube 118 flows to the downstream region 108b.
- the ink in the upstream area 106a flows into the downstream area 106b and the tube 118, and air flows into the upstream area 106a (FIG. 20B). At this time, ink remains in the upstream area 108a. Thereafter, when the ink is further sucked by the pump, the ink in the downstream areas 106 b and 108 b flows into the ink head 100. Further, the ink in the tube 118 flows to the downstream area 108b. Then, the ink is extracted from the ink path other than the upstream region 108a (FIG. 20C). Even if the suction is continued by the pump in this state, the air continues to be sucked from the tube 106, and it is difficult to extract ink from the upstream region 108a of the tube 108.
- cleaning operations in the tubes 106, 108, and 118 are performed in advance. Specifically, first, the cartridges 120 and 122 storing the cleaning liquid are respectively attached to the positions where the ink cartridges 102 and 104 are attached (FIG. 21A). Next, the valve 112 and the valve 116 are opened, and suction is performed from the lower surface 100a of the ink head 100 by a pump (not shown). At this time, regardless of whether or not the ink path 150 is filled with ink, it is necessary to allow the cleaning liquid and air to alternately flow into the tube paths 106, 108, and 118, and finally to reliably extract the ink and cleaning liquid. There is.
- the ink in the downstream regions 106b and 108b flows into the ink head 100. Further, the ink in the tube 118 flows to the downstream region 108b. Then, the cleaning liquid in the upstream region 106a is divided into the downstream region 106b and the tube 118 at the connection portion P1 (FIG. 21C). At this time, air flows into the upstream region 106a where the cleaning liquid was located, and the upstream region 106a is cleaned.
- the ink in the downstream area 108 b flows to the ink head 100.
- the cleaning liquid in the downstream area 106 b flows to the ink head 100.
- the cleaning liquid in the tube 118 flows to the downstream region 108b.
- the air in the upstream region 106a is divided into the downstream region 106b and the tube 118 at the connection portion P1 (FIG. 21D). At this time, the cleaning liquid flows into the upstream area 106a from the cartridge 120, and the downstream area 106b and the portion of the tube 118 where the cleaning liquid was located are cleaned.
- the cleaning liquid layer and the air layer are alternately formed in the tubes 106, 108, and 118 by repeatedly performing the cleaning liquid suction process and the air suction process.
- the tubes 106, 108, and 118 are cleaned by moving the cleaning liquid layer and the air layer in the ink path 150. Then, after the cleaning is completed, the cleaning liquid is extracted from the ink path 150 in the same manner as the above-described ink extracting process.
- the cleaning liquid and air may not be sufficiently allowed to flow through the tube 108 as in the case of the ink filling or extraction.
- the upstream region 108a of the tube 108 may not be sufficiently cleaned.
- the present invention has been made in view of the above points, and an object of the present invention is to provide an ink path that connects a plurality of ink cartridges and an ink head, and to accurately flow fluids such as ink, cleaning liquid, and air into the ink path. It is an object to provide an inkjet printer capable of performing the above.

- a tube 50 connected to the head 20 may be provided.
- valves 22 and 26 when the cleaning liquid cartridges 52 and 54 are connected or when the cleaning liquid cartridges 52 and 54 are removed, one of the valves 22 and 26 is opened and the other is closed. However, for example, both the valves 22 and 26 may be closed.
- the first time and the second time are stored in the microcomputer 32 in advance. However, the first time and / or the second time may be input by the user or may be changed as appropriate.
