Connecting to an External Device This instrument includes a USB connection terminal and a Bluetooth function (when the optional Bluetooth module is attached). The supplied USB cable (IF-A26) can be used to connect the instrument to a computer, or the Bluetooth communication function can be used to connect the instrument to a computer or a printer, allowing for data communication and printing.
z Connecting via USB Cable Connect the instrument to a computer with the supplied USB cable IF-A28 (2 m). Notes • To connect the instrument to a computer, the dedicated USB driver must be installed. The necessary drivers will be installed automatically. To install the drivers manually, use the drivers included with the software (such as the optional SpectraMagic NX software). • The instrument can be powered through the USB cable. (The battery must always be installed.) • When power is being supplied via USB, the charging lamp on the instrument’s panel will light up orange while charging.
z Connecting via Bluetooth Connect the instrument to a printer with Bluetooth communication functionality using the optional Bluetooth module. Notes • The instrument’s Bluetooth function enables data communication with a connected computer and printing from a Bluetooth printer. Connecting to both a computer and a printer/barcode reader at the same time, however, is not possible. • A simultaneous connection via the USB cable and the Bluetooth function is not possible. Should both connections be established at the same time, priority will be given to the connection via USB cable.
Communication setup Turn ON the Bluetooth function and configure the meter PIN code. Operating Procedure Start the procedure from the measurement screen. Press [MENU], and then use [◀] or [▶] to display the <Setting> screen. Memo To return to the previous screen, press [MENU] or [ESC]. Use [▲] or [▼] to move the cursor to “Communication setup”, and then press the [Confirmation] key.
Page 120
Use [▲] or [▼] to move the cursor to “ON”, and then press the [Confirmation] key. The instrument’s Bluetooth function is turned ON and the display will return to the <Communication setup> screen. The Bluetooth icon will be displayed in the status bar. To configure the Bluetooth PIN code, go to step 3 to continue.
{ Connecting to a Computer With the computer as a host, a connection to the instrument can be established using Bluetooth communication. Operating Procedure Verify that the instrument power has been turned Verify that the Bluetooth function on the instrument has been turned ON.
◎ Connecting to a Printer/Barcode Reader Connecting the instrument to a printer or barcode reader via the Bluetooth function enables printing of various data such as measurement results or scanning of names for data to save to the instrument. Notes • With the optional accessory CM-A219 Bluetooth module installed, the Bluetooth function of this instrument enables data communication to a computer, data printing to the bluetooth printer, and reading of data names from a barcode reader.
{ Instrument Preparation Connecting the Bluetooth module to the instrument, and turn ON the instrument’s Bluetooth function. (Refer to P.115.) Notes Until the instrument’s Bluetooth function is turned ON, registration and automatic printing configuration of the Bluetooth printer/reader is not possible. ...
PIN Code Configuration Enter the PIN set for the printer/barcode reader (already confirmed). Operating Procedure Start the procedure from the <Setting> - <Communication setup> screen. Use [▲] or [▼] to move the cursor to “Printer PIN code” or “Scanner PIN code”, and then press the [Confirmation] key.
Printing Data Print the sample or target data with the printer. Notes • The instrument must be connected to the printer in advance. • The instrument can only output text to the printer. Note that even if spectral graphs, color difference graphs, or other graphics are selected in the display type of the instrument, no graph will be printed. Operating Procedure Start the procedure from the <Target> or <Sample> screen. To print the target and sample display, press the [MENU] key with the data to be printed displayed.
Auto Print Measurement results can be automatically printed for every measurement. Notes • The instrument must be connected to the printer in advance. • The instrument can only output text to the printer. Note that even if spectral graphs, color difference graphs, or other graphics are selected in the display type of the instrument, no graph will be printed. Memo Auto print is set to “OFF” when the instrument is shipped from the factory. Operating Procedure Start the procedure from the <Setting>...

Calibration Interval Messages If the instrument has not been used for an extended period of time since the previous measurement, a message prompting white calibration will appear after start-up and before measurement. The time interval between the previous calibration and when the message is displayed can be configured. Memo The interval until the calibration is displayed is set to “8 hours”...
If the annual calibration notification message is set to ON, the annual calibration message will be displayed as the specified day nears. The date of the next calibration is specified upon initial startup or during KONICA MINOLTA calibration service (or maintenance) and cannot be changed. Press the [Confirmation] key.
User calibration You can perform calibration by using your own reference plate and calibration data instead of white calibration. The calibration data for user calibration can be specified by connecting the instrument to a computer and using the optional Color Management Software “SpectraMagic NX”. Users can select whether to use the user calibration data for measurement.
Zero calibration skip When shipped from the factory, the “Calibration (Excluding Zero Cal.)” button is enabled on the <Calibration> screen. If configuring to ensure that zero calibration is performed, disable this function. Memo Zero calculation skippable is set to “Disable (Perform zero calibration)” when the instrument is shipped from the factory.
Displaying Diagnosis Info. The results of the instrument status diagnosis using optional PC software are displayed. (* Support for this function is planned with optional PC software. It is not currently available.) Operating Procedure Start the procedure from the <Setting> screen. Use [▲] or [▼] to move the cursor to “Diagnosis info.”, and then press the [Confirmation] key.
Displaying the Instrument Information Display the product name, version, and serial number of the instrument. Operating Procedure Start the procedure from the <Setting> screen. Use [▲] or [▼] to move the cursor to “Instrument info.”, and then press the [Confirmation] key. The instrument information is displayed.
JOB Function Administrators can pre-register to the instrument workflows to be performed by the worker, allowing the worker to perform measurement according to the registered workflow. This selection screen is available when the job has been set in advance with the optional Color Management Software SpectraMagic NX.
Message List Error message: The operation is not correct. Follow the instructions displayed immediately. There is no xenon output. Restart and try measuring again. If the error occurs again, please contact the nearest service center. There was an error with color measurement device. Restart and try measuring again.
