Left to Right and Right to Left Calibrations
Left to Right Calibration is performed to achieve dot placement accuracy of all colors (Black, Cyan, and
Yellow) with respect to Magenta during the carriage’s left to right print sweep. Similarly, Right to Left
calibration is used to achieve d
ot placement accuracy during the carriage’s right to left sweep.
When the position of the test head is correct, then it would align perfectly with the reference color at
“0”
position, indicating that the error position is
“0”
. If the test Print H
ead’s pos
ition saved in the system is
inaccurate then it would not align at
“0”
position, but at some other point on the calibration scale. The
position at which the test head aligns perfectly with the reference head, indicates the error in position.
The
Left Calibration
Result is shown in the image below:
