Replacing the Print Head Caps

The print head caps (in two locations on the ER-642 and in one location on the ER-641) seal the nozzle surfaces of the print heads, preventing these surfaces from drying out and preventing dust from adhering to them.

When the following screen is displayed, it is time to replace the wiper.
