Epson L6490 Adjustment Program Here

The Epson L6490 Adjustment Program is a specialized, proprietary utility used by official service center technicians. It interfaces directly with the printer’s EEPROM (Electrically Erasable Programmable Read-Only Memory) chip via a USB connection.

Ensure there are no pending print jobs stuck in your Windows print spooler.
