ABSTRACT:
The ink jet printer nozzle clogging-preventive device of the present invention is characterized in that the device prevents air from entering the nozzle part and prevents the ink in said nozzle from drying and solidifying when an ink jet printer is transported, when the printer power is turned off, or when the printer is stopped to perform no printing for a long time while the power remains turned on.
That is, the device is characterized in that only one cap adhering device is provided as a means to cover the nozzle surface of a printer and said cap adhering device is allowed to perform an appropriate nozzle clogging-preventive action according to said printer conditions (such as non-printing condition with said printer power on, power-off condition, said printer transportation or long-period storage condition, and nozzle recovery operation condition).
