Yes, there are different ways of reseting the states of the capsules in the eInk panel.
There is a faster way, which can leave more ghosts behind, but works fairly well for text as the eInk is usually left mostly white or mostly black.
Images though tend to use all those intensities between white and black. Gathering the eInk back to a known state tends to require the slower collection method that looks like a double erase.
