The Epson R300 delivers reliable printing, but periodic maintenance routines can increase the waste ink counter and eventually trigger a ‘Service Required’ lock.

During head cleaning and maintenance cycles, excess ink is routed to internal absorber pads. The Epson R300 uses a software counter to estimate pad saturation and locks printing at a set threshold.

Understanding the Epson R300 Waste Ink Counter

With Wic Reset Connect, you can reset the Epson R300 waste ink counter quickly using a Windows PC, USB connection, and a valid reset key.

1. Step 1: Prepare a Windows PC + USB cable and connect Epson R300 directly. Keep Internet enabled for validation.
2. Step 2: Open Wic Reset Connect with admin privileges and verify device recognition for Epson R300.
3. Step 3: Paste the reset key, click Reset, and after completion power-cycle Epson R300.
