a) Cap unit
The cap unit is used to cap the print head nozzles during capping and cleaning. The portion that touches the face
plate is made from rubber. Two left caps are arranged for the printhead (six arrays of nozzles) installed in the
carriage.
During cleaning, the caps used for both suction and capping are used to suck ink from the printhead using the
suction pump.
Each of the right caps is used to cap the six arrays of nozzles.
This cap is used only for capping.
During capping, the caps are raised by the cap cams operated by the purge motor to cover the arrays when the
carriage has moved to the home position, thus protecting the nozzles.
