Scope 

This Operators Guide covers the KODAK VERSAMARK DT2 Print Station. 

This Operators Guide describes all operator procedures that can be 

performed at the print stations. Included is an overview of the print station 

functions, detailed instructions for each operator procedure, image 

troubleshooting information of use to an operator, and information about 

messages that are not errors. The Printhead Maintenance Guide provides 

full image troubleshooting information, and online help provides full error 

message information. 

Note: Some DT2 print station documentation and equipment still carries references 

to SCITEX S2 print stations. The DT2 was formerly manufactured by 

Scitex as the S2 print station. Operators, field engineers, and service 

engineers should recognize that any references to SCITEX S2 print stations 

also apply to KODAK DT2 print stations. 

The DT2 print station receives data from a data station (CD120, CD130, 

CD132 or similar model) that prepares bit-mapped data sent over fiberoptic 

connection. The DT2 print station may be controlled, through the data 

station, by a KODAK System Controller (CS400 or similar model) that 

monitors print station status and availability of data. 

Note: Due to continuing improvement efforts for the DT2 print station, small differences 

between the actual software and the screen representations in 

this guide may be seen. 

Software version 3.054 was the current version of operating software in 

use when this Operators Guide was released. Revisions to the operating 

software are typically issued to provide updated information for inkdex 

files used to identify various KODAK inks for use in the print station. If 

substantial differences between procedures contained in this Operators 

Guide and options available on-screen are found, please contact KODAK 

Inkjet Printing Solutions for a resolution. 

Basic knowledge of ink-jet printing terminology along with an understanding 

of the parameters that must be defined for the print station are 

required for operators to effectively use this guide.

Chapter 1. 

Overview 

The KODAK VERSAMARK DT2 Print Station is a component of an ink-jet 

printing system that accepts data in bitmap format as input and produces 

printed images as output. The substrate can be a continuous web or 

separate pieces of material. Images can consist of fixed text, variable text, 

and graphics. 

The print station (Figure 1.1) includes a fluid cabinet, an umbilical, a 

printhead, and a monitor and keyboard. The printhead receives ink and 

control signals from the fluid cabinet through the umbilical. The umbilical 

is a flexible assembly of ink tubes and electric cables. Ink pressure and 

vacuum for the printhead are provided by components in the fluid cabinet. 

The monitor and keyboard, referred to as the control terminal, are the 

operator interface to the print station.

Image data in bitmap format is sent from a data station in the printing 

system directly to the printhead through a fiberoptic cable. Control and 

status signals between the data station and print station are carried on an 

electrical cable. The block diagram in Figure 1.2 shows how the print 

station fits into a typical ink-jet printing system. 

Operator’s Guide 1 - 1


Print Station Functions 

The typical printing system requires a system controller, which may 

accept input data in various formats from a variety of inputs, including but 

not limited to a Local Area Network (LAN) connection and/or computer 

disks. A typical format is Ink-Jet Printer Data Stream (IJPDS). The 

controller uses controls in the IJPDS data according to job setup 

instructions and operator commands. The controller sends the data and 

controls to a data station.

Umbilical 



In printing systems without a system controller, the IJPDS data goes 

directly to a data station. The data station changes the IJPDS data into 

bitmap format and sends the bit-mapped data to the printhead at the print 

station. A printing system can have more than one print station and, 

therefore, more than one printhead. The data station determines which 

part of the bit-mapped data goes to a specific printhead. 

Print Station Functions 

The print station responds to the control signals from the data station with 

a series of operations. As part of the work of printing images, the print 

station performs the following functions: 

• Monitors the amount of ink stored in the fluid cabinet and withdraws 

ink and replenisher from external containers when needed. 

• Monitors ink concentration and adds ink or replenisher fluid when 

needed. 

• Heats the ink while starting the printhead, which controls 

condensation on the charge plate. 

• Supplies a controlled pressure to the ink, which forces the ink through 

the umbilical to the resonator in the printhead. 

• Supplies a controlled voltage for charging the ink drops in the 

printhead. 

• Supplies a controlled vacuum to the ink, which draws the ink from the 

catcher to the ink reservoir in the fluid cabinet. 

• Controls the stimulator amplitude, which determines the size of drops 

and exactly when the drops are formed. 

• Controls the timing of the charge voltage in relationship to the drop 

formation. 

• Orders the sequence and times of the states used to bring up, shut 

down, and clean the printhead. 

1 - 2 DT2 Print Station


Ink and Replenisher 

Ink and Replenisher 

The print station uses external supply containers for ink and replenisher. 

The following sizes of external supply containers are available: 

• 5.2 gal (20 L) cubitainer 

• 55 gal (209 L) drum 

• 275 gal (1045 L) tote 

The control terminal displays the level of ink stored in the internal tank, 

which is automatically filled from the external supply as ink is used. 

Replacing the external supplies can occur without stopping a job. The 

operator should check and, if necessary, replace the external ink or 

replenisher container after noticing a “check external fluid containers” 

message. 

Print Station Operations 

The print station performs different functions in accordance with a 

software routine contained in the on-board computer. Each major 

function, such as Clean, Printhead Ready, or Shut down, is divided into 

smaller segments referred to as states. These states are performed 

sequentially to accomplish the function. 

Operator Functions 

The operator can perform the following procedures at the print station. 

• Print station start 

• Printhead cleaning 

• Ink and replenisher container replacement 

• Charge voltage adjustment 

• Phase setting adjustment 

• Ink pressure adjustment 

• Print station shut down 

Refer to Chapter 3, “Print Station Operation” for detailed instructions. 


Chapter 2. 

Operator Controls

Ink or Replenisher Container Replacement 

The print station keeps about 2.6 L (2.75 qt) in the ink tank. Ink is 

constantly recirculated during operation at a rate of 0.5 L (0.53 qt) per 

minute. 

The print station regularly replaces ink that has been used for printing, 

drawing ink from an external supply container. Ink is drawn from the 

external supply only when the print station is in the Ready mode of 

operation. How frequently ink is drawn from the external supply depends 

on substrate speed, print density, and evaporation. The amount drawn is 

typically about 50 ml (1.5 fl oz). If the ink is too concentrated, the print 

station draws replenisher fluid instead of ink. 

The external ink supply container may be a 20 L (5.2 gal) cubitainer, 209 

L (55 gal) drum, or a 1045 L (275 gal) tote. Check and, if necessary, 

replace the external supply container when the print station constantly 

displays Check external fluid containers message. (The 

message may indicate a problem with the external lines or internal parts 

of the print station. Refer to Chapter 4, “Messages” for more information.) 

The containers can be replaced while printing. 

1. Disconnect ink or replenisher tubes at each print station (Figure 3.2). 

2. At the external ink or replenisher container, close the valve if the 

container is a drum (Figure 3.3) or tote. 

3. Remove the adapter and its nozzles from the container. 

Note: A spanner wrench may be required. 

4. Open the new container and remove its cap. 

5. Insert the adapter and its nozzles into the new container. 

6. Connect the supply tubing into the appropriate connectors at each 

print station. 

7. Open the valve at the external container if the container is a drum or 

tote.

Print Quality Maintenance 


Note: Test patterns are selected at the system controller. They are not selected 

from print station menus. 

Test Pattern 

The test pattern (Figure 3.4) is used to determine print quality. A variety of 

elements such as a dark bar, chevrons, and sample text are provided to 

allow the operator to look at all aspects of print quality. Figure 3.5 through 

Figure 3.7 show examples of print defects.

Charge Voltage Adjustment 

A charge voltage that is set too low causes dark defect (Figure 3.5). A 

charge voltage that is set too high causes pickout (Figure 3.6). In some 

cases, a charge voltage that is too low may cause trailing. 

Note: The charge voltage adjustment determines how much charge each drop 

is given. Charge voltage can be changed in 0.4-volt increments within a 

20 VDC range (±10 VDC of printhead charge voltage value set via the 

PARAMETERS ADJUSTMENT screen). 

Use the following steps from the PRINTHEAD READY status display to 

adjust the printhead charge voltage: 

1. Press ESC to display the CONTROL MENU screen. 

2. Select function 6 Adjust to display the PARAMETER 

ADJUSTMENTS screen. 

3. Note the current charge voltage setting for future reference. 

4. Press PAGE UP or PAGE DOWN to highlight the charge voltage 

adjustment function. 

Note: Extreme cases of pickout or dark defect may need changes of 5 to 10 

VDC to correct printhead performance. Small changes of about 2 VDC 

can correct minor cases of pickout or dark defect. 

Note: Increasing the charge voltage removes dark defects. Decreasing the 

charge voltage removes pickout defects. 

5. Remove print defects as follows: 

a. Press UP ARROW to adjust the charge voltage setting. Continue 

pressing until the test pattern displays pickout defect. Record the 

value. 

b. Press DOWN ARROW to adjust the charge voltage setting. Continue 

pressing until the test pattern displays dark defect. Record the 

value. 




c. If charge voltage setting cannot be set high or low enough to 

remove defect, the operating range must be changed. Refer to 

Appendix A, “Parameters Adjustment Screen Functions” for 

additional details. 

6. Return to PRINTHEAD READY status screen as follows: 

a. Press ESC 

b. Select function 1 Ready. 

Stimulation (Stim) Phase Setting Adjustment 

An improper stim phase setting results in ghosting (Figure 3.7). 

Note: The stim phase adjustment determines when a charge is given to the 

drops as they form. Phase settings are numbered 0 through 15. 

Use the following steps from the PRINTHEAD READY status display to 

adjust the stim phase: 




3. Note the current stim phase setting for future reference. 

4. Press PAGE UP or PAGE DOWN to highlight the stim phase adjustment 

function. 

5. Press UP ARROW or DOWN ARROW to adjust the stim phase setting. 

6. Check the printing to see the results of the adjustment. 

7. Continue to change the stim phase setting through all 16 different 

phase (0-15) settings. Record all phase settings that print test 

patterns of good quality. These settings are the phase window. 

8. Use the UP ARROW or DOWN ARROW to select a phase one value above 

the center of the phase window. Keep in mind that if the center point 

is 0, the value below 0 may be 15. Also, if the center point is 15, the 

value above the setting may be 0. 


a. Press ESC 


Ink Pressure Adjustment 

Changing the ink pressure can make the print darker or lighter by a very 

small amount. The Printhead Maintenance Guide describes the 

symptoms of improper pressure adjustment. 

Note: Printhead operation depends on the correct relationship of ink pressure, 

charge voltage, and stimulation phase. Changes to ink pressure usually 

require changes to the charge voltage and stimulation phase. Ink 

pressure can be changed in 0.066-psi increments within a range of 2.0 

psi. 




Use the following steps from the printhead ready status display to adjust 

the pressure: 




3. Note the current ink pressure setting for future reference. 

4. Press PAGE UP or PAGE DOWN to highlight the ink pressure adjustment 

function. 

Note: Even the small changes in ink pressure allowed here affect the 

printhead's response to charge voltage and phase settings. Try to limit the 

change to 0.25 psi. Do not set the pressure lower than 14 psi or higher 

than 16 psi. 

5. Press UP ARROW or DOWN ARROW to adjust the ink pressure setting. 

6. Check the printing to see the results of the adjustment. 

7. Continue to change the ink pressure until printing is same darkness 

as adjacent printheads. 

8. Adjust the charge voltage if the printing shows pickout, dark defect, or 

trailing. Adjust the phase if the printing shows ghosting. 


a. Press ESC.

image, but it may be concentrated at the ends or near the center of the 

image. 

dark line A narrow line of ink that appears in half-tone images and 

under certain conditions in text printing. The symptom results from an ink 

jet that releases drops when it should not. The extra drops are released 

when an adjacent ink jet is on, which indicates the charge circuits are 

shorted together.
