How To Clear Contents Of Clipboard Before Tool Takes Screen Print In Excel VBA

I've have a tool/code that takes the screen prints of the active window (when I press F9) and pastes it in a word document.

But whenever I do copy some text or any other image and when I press F9 to take the screen print of the active window. I get the text pasted into the word, this is because the clipboard content has text first and then the screen print of the active window.

Instead When I press F9, I wanted the below to happen

1. Content from the Clipboard should be cleared

2. Take the screen print

3. Paste it in the word document.

Note: My tool/code already does 2 and 3. Looking for 1 alone, ,
