Buyers please take note!
Please check that your printer is an original Epson printer before purchasing.
Before purchasing, please check whether your printer uses single-encryption or secondary encryption. If your device and decryption card use single-encryption (C7/C8), this printhead can be used with your printer. If your printer uses secondary encryption, please do not purchase this item. This printhead cannot be used with secondary encryption printers.

Note:
1. Please switch off the printer after entering a print value, otherwise the mainboard chip will burn out.
After inserting the printhead, please do not install a ribbon on more than 10 A4 documents.
This allows the new needle to break in, and then insert the ribbon. I hope you can operate carefully.

2. If the original printhead was broken and, in particular, ink leaked out, the mainboard may have burned out.
Therefore, please resolve the mainboard issue before replacing the printhead. Additionally,
The ignition cable F1, F2 of the mainboard can only be replaced by the original ignition unit, which has the same current rating and model.
If the detonator is replaced with one that has a higher current value and a different model, both the printhead and the mainboard may be damaged.

3. The printhead requires careful attention. It is easy to cause damage if a layperson replaces the printhead blindly.
There is a regulation stating that the printhead has no warranty and is delicate and expensive.
Please do not attempt to start up the machine and please handle it with care.

4. If you are not familiar with the device, it is recommended that you send the printhead to a repair station.
or find professionals to replace the nozzle to avoid unnecessary losses and hassle.
