Adjusting the print head angle relative to carriage
For optimal image printing, the print head nozzle array must be perpendicular to the head/
carriage unit's line of travel. Manufacturing limitations, however, make perfect alignment
impossible during mass production. The angle must be adjusted at the individual machine level.
The following describes this adjustment mechanism's components and their roles.
Slider L, the slider, and the rib attach the head/carriage unit to the CR support chassis. The rib
acts as a pivot for the slider's damping springs pressing the head/carriage unit to the rear. Slider
L has a head skew adjuster knob that shifts the slider back and forth, adjusting the angle of this
backward pressure. Rotating the head skew adjuster knob tilts the entire head/carriage unit, thus
adjusting the head nozzle vertical angle relative to the carriage unit's line of travel.
This knob offers 11 settings, from -5 to +5.
For the adjustment procedure, refer to Chapter 7, Section 7.2, [ 4 ].
