This section includes instructions for calibrating the Kodak Professional LED
Printers 20P/20R, Generations l and ll.
Kodak provides calibration applications for Windows NT and Macintosh systems.
See “Installing the Calibration Software” on page 3-1 for installation instructions.
See Section 3, Using Additional Calibration Features, for details about the
windows and dialog boxes for the application software and for additional
procedures not performed with each calibration.
Calibration is the process for creating and maintaining a Look-Up Table (LUT) that
produces the correct color balance for all images printed on the Printer. There is
sufficient variation among printers that each printer must be calibrated separately.
Before calibrating, make sure that:
•the paper path is threaded
•the printer status is “Online and Ready”
•no other printer applications are active
•the calibration application is running
•within the Kodak Professional Device Calibration software:
— at least one device is defined (see “Adding, Updating, and Deleting
Devices” on page 3-9)
— any needed changes to the configuration file are in place (see “Editing the
Device Configuration” on page 3-25)
•the densitometer is connected and calibrated
•the paper processor is in control

Calibrating the Printer
You need to calibrate the printer when you start the system up each day. You also
need to calibrate the printer when
•you change paper
•print quality is questionable
•the temperature at the site changes more than 5° F (2.8° C)
•if running more than one shift, at the beginning of each shift
NOTE: Most windows displayed in this section are from the Windows NT version
of the software. The windows for the Macintosh version of the software are
similar.
For information about editing the calibration settings (for example, you may want
to display a calibration graph only if calibration is out of tolerance), see “Editing
the Device Configuration” on page 3-25.
Starting the Device Calibration Software
1. Open the KODAK PROFESSIONAL Device Calibration application.
The display shows the KODAK PROFESSIONAL Device Calibration window.
If the device you need to calibrate does not appear on the window, you need
to add a calibration device. See “Adding, Updating, and Deleting Devices” on

Calibrating the Printer
Obtaining Densities
There are three methods for obtaining densities:
•from a file
•from a densitometer
•from a centralized densitometer (NT only and if the Centralized Densitometer
application is installed on your network)
The contents of the calibration configuration file determine which method you use
(see “Editing the Device Configuration” on page 3-25).
Obtaining Densities from a File
If the configuration settings include obtaining the density data from a file, the
display shows the Waiting for Density File dialog box.
If the configuration settings do not include obtaining the density data from a file,
go to either:
•“Using the Densitometer to Read Densitie s” on page 1-7
•“Obtaining Densities from the Centralized Densitometer (NT Only)” on
page 1-8
NOTE: T o create a density file, see “Creating a Density File for Use with Calibration”
on page 3-36.
1. Click OK to continue with the calibration process.
2. Go to “Completing the Calibration” on page 1-10.
1-6March 2001
Calibrating the Printer
Using the Densitometer to Read Densities
NOTE: For LED Gen I devices, you read only one neutral strip.
Do the following to scan the neutral (gray) patches on the processed test print into
the densitometer (refer to your densitometer manual for detailed instructions on
using the densitometer):
1. Slide the lever on the densitometer to position 15. Align the edge of the test
print with the lever on the densitometer. Gently feed the test print through the
densitometer to scan the patches labeled “even”.
2. Slide the lever on the densitometer to position 20. Align the edge of the test
print with the lever on the densitometer. Gently feed the test print through the
densitometer to scan the patches labeled “odd”.
3. Slide the lever on the densitometer to position 30. Align the edge of the test
print with the lever on the densitometer. Gently feed the test print through the
densitometer to scan the patches labeled “both”.

Completing the Calibration
1. If calibration is in tolerance, the display shows the LUT Attributes dialog
box.
a. Type a name or comment in the dialog box. The comment you enter will
appear on the Send LUT to Printer dialog box to identify the LUT file with a
name that is meaningful to you (up to 75 characters).
b. Click OK.
The new printing LUT is calculated and downloaded. The status bar shows
“Calibration Complete.”
2. If calibration is out of tolerance, it may be necessary to run four or more
iterations of the calibration cycle to achieve a successful calibration.
1-10March 2001
Calibrating the Printer
If the print densities are out of tolerance, the display shows a graph that
allows you to select the type of data and planes that you want to see
displayed.
a. Click OK.
March 20011-11
Calibrating the Printer
If specified in the configuration file, the display shows a list of options.
Re-read the densitometer values is most useful when the graphs show
an unusual plot. Rereading the test print lets you validate the graph, then
returns you to the Out of Tolerance dialog box.
Iterate again using a newly calculated calibration LUT allows you to
keep printing test prints with the newly created LUT without having to save
the LUT table.
Calculate and download a printing LUT and s top: When you select this
option, the LUT is calculated and the file is saved with the creation date
and time as its name.
Cancel and return the printer to its original state saves nothing. Any
corrupted data created after you saved the last time is thrown away.

Troubleshooting
CodeMessageExplanation
<11>LAMP_FAILUREThe lamp is either burned out or its output is at a level too low for
acceptable readi ngs. The densitome ter will not read strip s until the lam p is
replaced and the densitometer is re-calibrated.
<12>STRIP_RESTRAINEDDuring calibration, the calibration s trip was hel d or restrai ned as it pas sed
through the unit. Do not hold the strip as it is reading and make sure the
read path is clear of any foreign matter.
<13>BAD_CAL_STRIPDuring calibration, the calibrat ion stri p was un recogn izabl e. The s trip ma y
have been inserted backwards, upside down, or held so that it slipped on
the internal rollers. This also may be an indication that the strip needs to
be replaced.
<14>MOTOR_ERRORDuring calibration, a problem was detected with the drive motor. This can
occur if the strip is held back while reading.
<20>INVALID_READINGThe strip just read was not recognized by the densitometer.
<21>WRONG_COLORAfter a strip reading, the step wedge just read was not the color specified
for that pass or strip as defined in the densitometer editor menu.
<23>NEEDS_CALIBRATIONThe calibration check that was done immediately after reading a strip
indicated that the unit needs calibration. This occurs when the reading
taken from the opal glass after the strip exits the unit differs from the
reading taken during calibration by more than the internal tolerance
(default is 0.1 X, Y, or Z). The tolerance can also be changed by the RCI
command CC (Check Cal tolerance).
<26>NO_VALID_DATAThe measure type is set to CONT and the strip that was read contained
nothing but base material. Base material is defined as measuring less
than 0.5D in the visual channel. For negative (black) based materials,
base material is defined as me asurin g less than twice the reflect anc e of a
measurement taken near the trailing edge of the strip. the densitometer
uses a measurement taken at about 0.25 inches from the trailing edge of
the strip to determine i f it is posi tive o r negati ve bas ed. Any m easu rement
greater than 10% reflectance is considered positive based; anything else
is considered negative based.
March 20012-13
Troubleshooting
CodeMessageExplanation
<27>BAD_PATCHIf the Pattern Recognition comparison window is set to 0 or 1, this error
may result when a single patch on the strip is bad due to dirt, smears,
creases, etc. (See expl anation of CW command for more informat ion.)
<30>BAD_STRING_LENGTHA strip definition string received as part of the DS (Define Strip) R CI
command did not contain the correct number of characters.
<31>BAD_CHARACTERA non-printable character was received in one of the name fields (strip
name or pass name). Print abl e cha rac ters are in the range 0x20 to 0x7E,
inclusive.
<32>BAD_MEAS_TYPEThe value for the measure type field was greater than 3. Valid values are
0 through 3.
<33>BAD_COLORThe value for the color field was greater than 9.
<34>BAD_STEPSThe value for the number of steps was greater than 72.
<35>BAD_STOP_LOCATIONThe value for t he guide setting was less than 4 or greater than 30.
<36>BAD_OUTPUT_TYPEThe value for the output type was greater than 5.
<37>MEMORY_ERRORThe definition could not be stored.
<38>BAD_N_FACTORThe n-factor (used in Dot calculations) is either less than 0500 (0.500) or
greater than 4500 (4.500).
<39>STRIP_DOESNT_EXISTThe SD command was issued and the requested strip does not exist.
<3A>BAD_MIN_MAX_VALUEThe value for the min/max field was greater than 4.

Advanced Features of the LED II Calibration Software
The Calibration Software for the KODAK PROFESSIONAL LED II Printer
20P/20R provides automated neutral density printer calibration and is designed to
be used without assistance from technical experts. The advanced calibr ati on
features provided by this product enable you to customize the calibration of the
printer. To use the advanced features, you should understand image science
technology and the implications of manipulating neutral density calibrations.
IMPORTANT: Printer calibration should not be mistaken for color management.
Color management is provided by software applications that are
independent of the printer and the calibration software.
Viewing Graphs
The View Graphs feature provides access to the available graphs from the most

Using Additional Calibration Features
Creating a Density File for Use with Calibration
During calibration, you have the option of obtaining density data from a file or by
scanning a processed test target through an X-RITE DTP 36 densitometer. The
option is determined by the entry in the device configuration file. If the
configuration file is set up to receive density data from a file and you are creating
the file:
1. Scan the print into your densitometer.
2. Save the data to file using the density data file format specification (see “File
Formats” below). The Kodak Device Calibration Software does not perform
this function.
3. Move the density data file that you just saved to the “Dens” folder within the
device folder for your specific device. The filename should match the Density
Source File selected on the Density Source tab of the Edit Configuration
window (see “Editing Information on the Density Source Tab” on page 3-28).
File Formats
NOTE: If a file contains data in a tabular format, each entry may be separated by
multiple spaces and tabs; however, when the file is saved by the application,
each group of multiple spaces and tabs is automatically converted to a
single tab.
This section describes how to install the X-RITE DTP 36 Densitometer, including
changing some of the attributes on the Edit Configuration window to
accommodate the densitometer.
IMPORTANT: The supported densitometers use a RS-232 interface for
communication to the host. Each platform uses different
designations to identify the RS-232 ports.
To install the densitometer:
1. Connect the appropriate cable (provided by the user, supplier or with the
densitometer) between the densitometer and the host computer.
NOTE:For the X-RITE DTP 36 Densitometer:
•Remove the protective strip (for shipping) from the densitometer.
•Verify that the densitometer is configured with the factory defaults. (Refer
to the densitometer manual for this information.)
•Perform an initial calibration of the densitometer. (Refer to the
densitometer manual.)
2. Run the calibration software for the printer and click the Edit icon to access
the Edit Configuration window; see “Editing the Device Configuration”
beginning on page 3-25.
