7. Printing
Nozzle Testing
Before starting with calibration tests, the Print Heads should be checked for blockage. Each Print Head
has multiple tiny nozzles through which ink drops emerge and get deposited onto the print medium.
Any nozzle blockage can compromise the print quality by forming discolored horizontal streaks or
bands.
The good and bad nozzle test results are shown in the image below:
Fig 26: Displaying the Good and Bad Nozzle Test Result
To check the nozzle, click on the Check Nozzle icon available on the Quick Access Toolbar, as shown
below:

Print Head Calibration
The Print Head calibration is categorized into the following types:
• Mechanical Check: Includes Vertical Check and Angle Check
• Software Calibration: Includes Horizontal Calibration and Step Calibration
Let’s discuss the above-mentioned checks and calibration one by one in details.
Note: Mechanical checks are performed by service engineer, thus these checks and their description
are not included in user manual.
Opening the Calibration Wizard
Print Heads should be calibrated to ensure good printing quality. To open the Calibration Wizard,
click on the Main MenuToolsCalibration Wizard path, as shown below:
Fig 28: Selecting the Calibration Wizard Option
This should bring up the Calibration Wizard which is shown below:
Fig 29: Displaying the Calibration Wizard
Page 22 of 41
VULCAN
When you press the Next button, we redirect to the software calibration screen, as shown in the
below images:
Fig 30: Displaying the Bidirectional Check in Calibration Wizard
Let’s discuss each test and their result one by one in upcoming section. Mechanical checks are
performed by Service Engineer, thus these checks are not discussed in the user manual.
Page 23 of 41
VULCAN
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 BiDirection offset, the Left to Right and Right to Left print would align at some other point on the scale.
The Bi-direction Calibration result is shown in the image below:
Fig 31: 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.
Page 24 of 41
VULCAN
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.
The Left Calibration Result is shown in the image below:
Fig 32: The Horizontal Left Check
The Right Calibration Result is shown in the image below:
Fig 33: The Horizontal Right Check
Page 25 of 41
VULCAN
Step Calibration
The printer step calibration is performed to verify and correct media feeding. The printer prints a
complete image pass by pass. A pass is the horizontal carriage sweep perpendicular to the media
movement. After each pass the printer moves the media forward for the next pass. This movement of
media is called a step. The distance by which the media is moved is called the step size and it has to
be accurate. Step size errors cause horizontal white or dark bands to appear in the print output. Step
size needs to be adjusted for multiple factors like thickness and roughness of the print media etc. Step
calibration should be used to fine adjust the step size and has to be done for each desired pass.
The Step Calibration result image is shown as below:
Fig 34: Displaying the Output of the Step Calibration
From the above figure, you get the accurate step adjust correction value. The correction value is either
positive or negative. If the value is positive, then add it in the current step adjust value for the Print
Head calibration. On the other hand, if the value is negative, then subtract the value from the current
step adjust value. From the above, you can conclude that the pattern is corrected at “0” position.
The Step Calibration and it’s parameters are shown in the image below:
Fig 35: The Step Calibration Parameters
Follow these steps to perform step calibration:
Step 1: Select the desired pass from the list and click on the Print button (Refer to Fig 35).
Step 2: Feed the correction value in the Revise field (the correction value up to two decimal places)
(Refer to Fig 35).
Step 3: Click on the => icon (Refer to Fig 35) on the Step Calibration window. The correction value
result will be reflected in the Step field (Refer to Fig 35). The same step value will also be displayed
in the Steps field on the Quick Access Toolbar.

Setting Print Origin
Print origin sets the print starting point with the left limit switch 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 36: 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:

Step 1: Multi-fold the tissue paper 3-4 times.
Step 2: Hold it from one end such that other end remains flexible and extra pressure is not getting
applied on the heads.
Step 3: Wet the other end of the tissue paper with solvent.
Step 4: Wipe it softly once, to soak all residue inks on the nozzle plate.
Now, the Print Head gets wiped.
Note: Please strictly follow the below mentioned instructions:
• Avoid using the same tissue paper to wipe the Print Head.
• Wiping with dry and inferior quality tissue paper will damage the nozzle film by making scars
(see image in next page).
• Strictly use recommended tissue paper (Contact your dealer for tissue paper).
• Always use wet tissue paper to absorb the residue ink.
• Don’t wipe hard, just absorb the residue inks on nozzle plate.
• Softly touch with a lint free bloating tissue paper (duly wet by cleaning solvent)by changing
the tissue paper position with respect to nozzle plate.
• Do not apply force while absorbing residue inks with tissue paper after purging.
• Leaving head plate uncapped while printer off, will block nozzles permanently due to ink
solidification.

• Color bar should always be enabled while printing and idle spray should always be enabled
for long life of the Print Head.
Head Purging
Head purging refers to the method in which heads are cleaned by forcing pressurized ink though the
nozzles.
Note: VULCAN must be ON always.
Follow these steps to start the head purging process:
Step 1: Turn ON the Negative Pressure knob of the color on which user wants to perform the purging,
as shown below:
Fig 54: Performing Head Purging
Please make sure that all other colors Negative Pressure knob must be turned OFF.
Step 2: Press the Cleaning button to start the purging process (Refers to Fig 54).
Now, the Print Heads get cleaned.
Head Spraying
Head spraying should be performed only when small percentage of nozzles are blocked. This method
is used to avoid mixing of colors. When heads are sprayed all the nozzles are actuated at a high rate
which helps in opening up dry nozzles of the printer. To perform head spraying, click on the Spray
button available under the Quick Access Toolbar, as shown below:
