Flushing cover

Open this cover when cleaning around the print heads and when replacing the flushing sponge. Leave this cover closed when not cleaning around the print heads or replacing the flushing sponge.

Media clamp

This clamps the left and right edges of the media.

Each clamp holds down the left or right edge of the media, keeping the media from coming loose and preventing fuzz on the cut edge of the media from touching the print heads.
Grit roller Transports the media.
Pinch roller

Each pinch roller is lowered/raised according to the operation of the loading levers.

Lowering a loading lever lowers the pinch rollers, clamping the media.
