I tried taking some photos of our R3000 yesterday, but with the tight space, the fact that I'm right handed trying to work the camera and Q-tip myself, it was a bit difficult to get good photos...
I hope this helps~ Dana
The photo below shows the R3000 capping station, and wiper blade in the down position (labeled with red arrow)
Using two fingers, I used one to push the capping station over to the right (to give my other finger and wiper blade more room), then with the other finger pulled up on the white wiper blade frame and it easily rotated up as shown in the photo below. The top edge of the wipe blade has a slight curve towards the capping station, which is the side that wipes the bottom of the print head (so, will likely be dirtier). Don't touch the wiper blade with your bare hands, because the oils from your skin can cause damage to the print head. Gently wipe the sides of the wiper blade with a Q-tip moistened with PiezoFlush (pictured) or warm distilled water. After cleaning, use a dry Q-tip to absorb excess liquid before lowering the wiper blade back into place, and move the print head back to the right side of the printer.
