Croma24 Service Manual
The “Current Heads (Y, M, C)” view represents the alignment of the
heads as they are currently entered. This is just an overview of all
heads and how they are aligned. Do not attempt to align the heads
using this view.
The “Color Horizontal Head-to-Head Calibration” checks the align-
ment of the nozzles horizontally and allows corrections when re-
quired. Just enter the value below the set of lines that are correctly
aligned. Be careful that you are aligning the correct color by observ-
ing the C (cyan), M (magenta), and Y (yellow) on the right side of the
plot.
The “Color Vertical Head-to-Head Calibration” checks the alignment
of the nozzles vertically and allows corrections when required. Just
enter the value below the set of lines that are correctly aligned. Be
careful that you are aligning the correct color by observing the C
(cyan), M (magenta), and Y (yellow) on the right side of the plot.
Deadband Alignment
Deadband calibration compensates for minute differences created
when bidirectional printing is used. Unidirectional printing is not
affected by deadband. There are four types of deadband tests: slow
deadband, fast deadband, fast deadband; vertical lines (all), and fast
deadband; vertical lines (one).
Figure 3-11. Deadband Slow/Fast.
Figure 3-11 shows what the display will look like when printing
either the fast or slow test if it is out of alignment. A correctly
aligned printer will appear as if there is only a series of vertical lines
printed. No difference between the three segments of lines would be
apparent.
The SLOW DEADBAND calibration is a precision test that checks
the firing time of the jets as related to the forward and reverse
direction.
