6. Printer Software Operations
Setting the Print Origin
Print origin sets the print starting point with right most print head position as the reference point. It
can be set by two ways; moving and positioning the carriage and typing the offset value directly in the
given field.
Follow these steps to change the print origin:
Step 1: Move the carriage at the position from where you want to start the printing by clicking on
the left and right buttons on the Quick Access Toolbar, as shown below:
Fig 23: Adjusting the Carriage Position
Step 2: After positioning the carriage, click on the Set print origin icon on the Quick Access Toolbar,
as shown below:
Fig 24: Selecting the Set Print Origin Option
On clicking the Set print origin icon, the current position of the carriage gets updated in the Origin X
text box, as shown below:
Fig 25: Displaying the Origin Value
Now, the printing origin gets set. Additionally, you can also enter the print origin value manually in
the Origin X field under the Print Parameter section.

Calibrating Wizard
Print Heads should be calibrated to ensure good printing quality. To open the Calibration Wizard, click
on the Main Menu→Tools→Calibration Wizard path, as shown below:
Fig 26: Selecting the Calibration Wizard Option
This should bring up the calibration wizard which is shown below:
Fig 27: Displaying the Calibration Wizard

When you press the Next button, we redirect to the software calibration screen, as shown in the below
images:
Fig 28: Displaying the Printer Calibration Options
Let’s discuss each user related test and their result one by one in upcoming section.
Horizontal Calibration
Horizontal Calibration checks the bi-directional, 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. Let’s discuss each type of horizontal test one by one.
Bi-direction Calibration
Bi-directional calibration is performed to achieve dot placement accuracy between the “Left to Right”
and “Right to Left” print sweeps. If the bi-direction offset value is correct, the Left to Right test print
would align accurately with the Right to Left test print at“0” position. In case of error in the Bi-
Direction offset, the Left to Right and Right to Left print would align at some other point on the scale.

Page 19 of 40
FABJET GRAND
The Bi-direction Calibration result is shown in the image below:
Fig 29: 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.
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.
