2.12.1. Wiper station
The printhead must be wiped to remove ink cross-contamination and particulates. The
cylindrical wiper rotates to wipe the entire width of the printhead. The roller rotates for the
duration of the lift-dwell-lower cycle. The intent is not to merely blot the nozzles but to have
functionally translational wiping. The wiper is programmable and can be rotated numerous
times to perform multiple wiping operations. Once wiping is complete the station drops back
down. A metal transfer roller cleaned by a doctor blade helps remove ink from the wiper. The
removed ink dries or evaporates within the wiper station. When the wiper becomes
contaminated to such an extent that it is no longer effective, the wiper must be replaced by
unlatching the two wiper retaining clips. These clips can be released while the maintenance
module is in the wipe position.
2.12.2. Printing platen
The platen provides a smooth writing surface and the correct spacing between the
media and the printhead. During printing, the paper below the printhead is maintained at a
fixed dive angle from the drive roller nip and platen below the nozzles to ensure print quality.
Along the center of the platen there are four Porex (tm) micro sponges to collect ink
overspray.
