b) Wipers
The wipers are operated by the purge motor and perform the wiping of six nozzle
arrays simultaneously of the printhead. One pairs of wiper blades are used to
provide improved wiping performance. The wiping operation is performed in a "slide
wipe" style where the wiper blades slide based on the forward rotation of the purge
motor. This action is performed after the printing or suction operations using a
constant-speed movement in the front direction as viewed from the printer front.
The wiper cam raises the wiper unit to the wiping position. The wiper blade, which is
positioned perpendicular to the printhead, wipes the entire face plate of the
printhead, and then the narrow blade is used to wipe the nozzle array.
After wiping, the wiper blades are cleaned before they are set at the wiping position
so that maximum wiping performance can be maintained.
In the wiper blade cleaning, ink that was wiped from the head section is rubbed off
by an ink scrapping receptacle connected to the maintenance cartridge, and then the
blades are wiped off with a blade cleaner.
