Body:

Step 4: Reset the Waste Ink Counter (The Main Task)

In the tool window, click the "Main" button under the "Waste Ink Pad Counter" section – this resets the primary waste ink counter.
If you also see a "Platen" or "Ink Absorber 2" option, click "Platen" as well (some printers have two pads).
A progress bar will appear briefly. When finished, you’ll see a confirmation message.
