The Epson L455 is a popular all-in-one ink tank printer designed for high-volume, low-cost printing. Like all inkjet printers, it contains an internal waste ink pad that absorbs ink during cleaning cycles. To prevent overflow, Epson hard-codes a counter into the printer’s firmware. Once this counter reaches a predetermined limit (typically 70,000–80,000 purge strokes), the printer locks down and displays a "Service Required" error (e.g., "A printer’s ink pads are at the end of their service life" or error code 0x69). This paper examines the third-party software solution known as the for the L455, detailing its technical function, application procedure, legal implications, and risk assessment. epson resetter l455
The (often named AdjProg.exe or L455_Resetter.exe ) is a third-party adjustment program that communicates with the printer’s EEPROM via USB to reset the waste ink counter to zero. Warning: Using this tool voids your warranty
Connect your printer via USB (Wi-Fi resetting is often unstable). Open AdjProg.exe and select the model. Like all inkjet printers, it contains an internal
An (often generically called AdjProg or WIC Reset Utility ) is a small software program that communicates directly with the printer’s EEPROM (electrically erasable programmable read-only memory). It forces the waste ink counter back to zero.
When you see the alternating red lights and the "Service Required" alert, the printer is effectively saying, "My waste tanks are full." However, in many cases, the pads are not physically overflowing; the electronic counter has simply hit its pre-set limit.
