Epson DX7 Printhead First coded - F189010

The Epson F189010 printhead "first coded" (also known as 1st coded) is an original Epson DX7 solvent-resistant printhead model designed for certain solvent-based Chinese DX7 printers manufactured after the end of 2013. It features 8 channels with 180 nozzles each, supporting a native resolution of 1440 dpi, a droplet size range from 1.5 to 21 picoliters, and firing frequency of 8 kHz. The 1st coded version is locked to specific printer control boards installed post-2013, and is one of three versions available: not coded, 1st coded, and 2nd coded.

The first coded heads have circuit board IDs that start with the letter G or letters following G, and the first four digits on the board are under 1530, indicating the older coding compared to the 2nd coded version. It is important to confirm that the printer’s existing printhead is 1st coded before installing this model, and changing head cables along with the printhead is recommended for optimal compatibility and performance. This Epson DX7 Printhead First coded - F189010 is compatible with eco-solvent and mild solvent inks and serves printer models such as those by Sanyi Tech, MeiTu MT-StarJet series, and others made post-2013.​
