Epson printhead installation instructions
At present, Epson printheads are widely used in various piezoelectric printing machines. When purchasing a new printing machine or replacing the piezoelectric print head and installing the new print head, you must pay attention to these instructions:
1.The installation of the printhead is very important. The main reason is that it is more expensive and the installation error may greatly affect the normal printing state of the piezoelectric nozzle! In other words, a little carelessness will cause damage to your nozzle.
2.Before installing the piezoelectric print head, first make sure that the machine is in normal motion, the machine grounding wire is perfect, the voltage on the car board and printhead is normal.
3.It is normal to use software to test all aspects of fedar printer movement, the encoder strip reading is normal, and the indicator light is normal.The operator's hands must not be sweaty or vaporous.In addition, remember not to wear plastic cloths that tend to cause static electricity. It is best to have static rings on your hands when conditions permit. Be sure to turn off the power and unplug the power cord when installing!
4.Generally, there are no less than two nozzle data plugs. Check whether it is flat. It is better to use a new plug and plug it into the print head. The line scale of the nozzle line is generally divided into two sides, one side is in contact with the circuit, the other side is not in contact with the circuit, and the direction is not wrong.
5.The nozzle plug is connected to the car board: firstly, operate without power when the printer is turned off! The position of the line coming out of the nozzle must be clarified before you start. Take pictures before installing and mark each line!
6.After all installations, check three to five times, and turn on the power after confirming that there is no problem. It is best not to turn on the nozzle first. Use the ink pump to lead the ink first, and then turn on the power of the nozzle. If the whole machine has a power switch, First check whether the flash spray is normal. If the flash spray is normal, the installation is successful. If the flash spray is abnormal, please turn off the power immediately to check if there is any problem elsewhere. This is under the condition of confirming the new print head.
7.The printhead must be installed carefully, and the work before installation must be at least, and it must be organized.
8.Don't let the ink drip onto the data line when inserting the damper, because the ink flows down the data line and will directly enter the circuit, which may cause a short circuit and burn the head directly.
