2.2.6 Cap Mechanism
The cap mechanism prevents the printhead nozzles from drying or keeps bubbles horn forming
inside the nozzle while the printer is not in use. The pMter perfimns this operation automatically
when print data is not received or when the printer power is turned off during the printing or ink
system operations. (Since the power switch is equipped with a semndary circuit, this operation cart
be performed.) Also this printer has 2 caps, 1 for the blackhead and 1 for the color head.
2.2.7
Wiping Mechanism
The wiping mechanism cleans the surface of the printhead nose when the printer is in the ink
system sequence. The wiper drive gear transmits @wer from the paper feed motor via the clutch
gear. When the wiper is raised up (against the printhead surt%ce), the hook for securing the
carriage to the home position is raised, too. When the wiper goes down toward the bottom frame,
the hook goes down, too. Both the black head and the color head are cleaned by this wiper.
