The
Bi-direction Calibration Result
is shown in the image below:
Fig 28: The Bi-Direction Calibration Output
Based on the above figure, you can notice that the Bi-direction calibration is good at
“0”
position. The correction
value is
“0”
which means you need not to correct the bi-direction value. Sometimes, the correction value can
either positive or negative. If the correction value is positive, then you need to add it in the current bi-direction
adjust value or subtract the same if negative.
Horizontal Calibration
Horizontal Calibration checks left and right alignment and corrects it by adding or subtracting the correction value
from the default set value. It has to be performed for each print mode, whichever is required.
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 dot 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 Head’s position 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.
