1, the installation of piezoelectric photo printer nozzle is critical, the main reason is that the nozzle is more expensive, more delicate nozzle, installation errors may affect the piezoelectric print head to the normal print state. That is to say a little carelessness will lead to your nozzle damage. Be sure to follow the instructions steps to operate, in order to avoid damage caused by improper operation nozzle unnecessary losses.
2, before installing the piezoelectric nozzle, first of all to ensure that the machine is moving normally, the machine is connected to the ground wire is perfect, the voltage on the car plate is normal, the nozzle power supply voltage is normal. The choice is to use a multimeter to measure whether there is static electricity on the machine, the voltage of the car plate, and the supply voltage of the nozzle, the general supply voltage Epson five generations of 42V DC.
3, the general nozzle are not less than two nozzle data plug, check the plug wire thread is tilted pins, is flat, with a new plug, insert the plug with the nozzle, plug firmly do not have any tilt. Sprinkler head line scale generally positive and negative sides, one side of the contact circuit, the other side does not touch the circuit, the direction of not wrong, must be inserted several times more checks, to confirm there is no problem in the nozzle mounted on a small frame.
