Abstract:
There is provided a printer including: a liquid jetting head; a receiving section; a waste-liquid storing section; a connecting channel connecting the receiving section and the waste-liquid storing section; a pump; and a controller. The controller executes: printing; recovering nozzles; discharging the liquid, which is present in at least one of the receiving section and the connecting channel, to the waste-liquid storing section, after the recovering of the nozzles. Under a condition that there is no input of the print data before the discharging of the liquid, the controller executes the discharging of the liquid continuously after the recovering of the nozzles; under a condition that there is an input of the print data before the discharging of the liquid, the controller executes the printing after the recovering of the nozzles and then executes at least a part of the discharging of the liquid after the printing.

Claim (Index 14):
The printer according to  claim 1 , wherein the receiver includes a cap having a first recessed portion facing certain nozzles as a part of the plurality of nozzles and a second recessed portion facing other nozzles different from the certain nozzles as the part of the plurality of nozzles, the cap being contactable with the liquid jetting head to cover the plurality of nozzles;\n wherein the printer further comprises a switching valve which is provided at an intermediate portion, of the connection channel, located closer to the cap than the pump, wherein the connection channel includes:\n a first channel connecting the first recessed portion and the switching valve, \n a second channel connecting the second recessed portion and the switching valve, \n a third channel connecting the switching valve and the waste-liquid storing section, wherein the pump is arranged at an intermediate portion of the third channel, and \n a fourth channel connecting the switching valve and the waste-liquid storing section, wherein the fourth channel is open to atmosphere; \n wherein in a case that the recovering of the plurality of nozzles is executed, the controller controls the liquid jetting head, the pump and the switching valve to execute a first suction purge operation and a second suction purge operation, wherein the first suction purge operation includes:\n causing the cap to make contact with the liquid jetting head to cover the plurality of nozzles, \n controlling the switching valve and the pump to activate the pump in a state that the first channel and the third channel are communicated with each other to thereby execute sucking the liquid from the certain nozzles as the part of the plurality of nozzles, \n controlling the switching valve to communicate the second channel and the fourth channel with each other to thereby allow the second recessed portion to be in an atmosphere-open state in which the second recessed portion is open to the atmosphere; and \n wherein the second suction purge operation includes:\n causing the cap to make contact with the liquid jetting head to cover the plurality of nozzles, \n controlling the switching valve and the pump to activate the pump in a state that the second channel and the third channel are communicated with each other to thereby execute sucking the liquid from the other nozzles, and \n controlling the switching valve to communicate the first channel and the fourth channel with each other to thereby allow the first recessed portion to be in the atmosphere-open state in which the first recessed portion is open to the atmosphere; \n wherein in a case that the discharging of the liquid to the waste-liquid storing section is executed, the controller controls the switching valve and the pump to activate the pump in a state that the third channel and the fourth channel are communicated with each other to thereby execute discharging the liquid in the fourth channel to the waste-liquid storing section; and wherein under a condition that there is the input of the print data to the controller before the discharging of the liquid inside the fourth channel to the waste-liquid storing section, the controller controls the liquid jetting head, the pump and the switching valve to execute the first suction purge operation and the second suction purge operation before the printing and to execute at least a part of the discharging the liquid in the fourth channel to the waste-liquid storing section after the printing.
