s10: when it is detected that the ejection head 40 is not clogged.
S11: when the ink in the buffer bin 20 is less than the first preset value, the buffer bin 20 is vacuumized.
Specifically, a liquid level sensor is disposed in the buffer bin 20, and when the liquid level sensor senses that the liquid level of the ink in the buffer bin 20 is lower than a preset value, it indicates that the ink in the buffer bin 20 is less than a first preset value, and the ink needs to be replenished into the buffer bin 20. Before replenishing the ink, still carry out evacuation processing to surge bin 20, avoid remaining the air in surge bin 20, still make simultaneously in the surge bin 20 be the negative pressure state, make things convenient for surge bin 20 to absorb the ink.
S12: the first valve 11 is opened, and the ink tank 10 supplies ink to the surge tank 20.
The first valve 11 between the ink barrel 10 and the buffer bin 20 is opened, so that the pipeline between the ink barrel 10 and the buffer bin 20 is in a communication state, and the ink in the ink barrel 10 flows into the buffer bin 20 to be replenished into the buffer bin 20.

As shown in fig. 2 and 3, in another aspect, the printer further includes an ink flushing device 50, and the ink distribution rail 30 is provided with a flushing port, and the flushing port is connected to an outlet of the ink flushing device 50. The method for controlling an ink supply line of a printer further includes:
s20: when a blockage of the spray head 40 is detected.
After the nozzle 40 is blocked, the nozzle 40 cannot normally jet ink, which reduces the printing effect of the printer, and the nozzle 40 needs to be flushed at this time, so that the blocking substances in the nozzle 40 are flushed out, and the nozzle 40 can continue to normally work.
S21: the ink flushing device 50 injects ink into the ink distribution rail 30.
In the prior art, when the spray head 40 is blocked, one method is to take out the spray head 40, then clean the spray head 40, and complete the maintenance of the spray head 40; another method is to introduce a high-pressure gas into the head 40 so that the head 40 can smoothly eject ink. It is clear that the first method of treating the nozzles 40 is too complex and requires professional maintenance personnel to treat them, which greatly increases the maintenance cost, and the second method of treating the nozzles 40 causes air to enter the ink supply channels of the printer, which reduces the subsequent printing effect. In the invention, the pressure of the ink in the ink distribution rail 30 is increased by injecting the ink into the ink distribution rail 30, so that the ink in the ink distribution rail 30 washes the spray head 40, and the maintenance of the spray head 40 is completed.
