Troubleshooting
If an abnormality has occurred with the instrument, take the necessary actions as given in the table below. If the
instrument still does not work properly, turn the power OFF and temporarily disconnect the battery. Reinsert the
battery and turn the power back ON. If the symptom remains, contact a KONICA MINOLTA-authorized service
facility.
Symptom Check Point Action
The instrument does not
start up even though the
power is ON, or it turns
o immediately.
Has the battery been inserted
correctly?
Is the battery dead?
Insert the battery correctly, or use the AC adapter or
USB bus power to charge the battery.
Measurement cannot be
performed even by
pressing the
measurement button.
Is measurement still in
progress?
Wait until the beep indicates that measurement is
complete, or verify that the LCD has changed before
performing the operation.
No beep can be heard.P.108 “Beep”, and check the
beep settings.
Is a screen where
measurement is possible
displayed?
The measurement button must be pressed while a
screen that allows measurement (e.g. Calibration,
Target, or Sample screen) is shown.
Is the viewfinder open?
Use the viewfinder lever to securely close the viewfinder.
If the inside of the integrating sphere is illuminated and
shining, the viewfinder lever is not closed.
Remove any foreign matter, etc. caught in the viewfinder
lever components.
Measurement results are
abnormal.
Is the specimen placed
properly?
The measurement results may be aected if
measurement light leaks. Set the instrument so that the
sample is as close to the target mask surface as possible.
Is there any foreign material on
the surface of the target mask
or around the specimen
measuring surface?
Measurement results may be aected if foreign matter
becomes caught between the specimen and the target
mask surface. Clean the specimen surface or the target
mask measurement surface according to the specified
method.
Are there marks on the surface
of the target mask around the
specimen measuring port?
If the sample and the target mask surface are not in
contact due to a dent or the like, the measurement results
may be aected. To replace the target mask, please
contact a KONICA MINOLTA-authorized service facility.
Is there foreign matter or other
dirt adhering to the inside of
the integrating sphere?
Foreign matter or dirt larger than several mm may
aect the measurement results. Foreign matter and
dust inside the integrating sphere can easily scratch
the barium sulfate paint on the inside of the sphere.
Use a blower to blow o those objects. If such objects
cannot be removed with the blower, zero calibration
and white calibration may improve performance.
Is the target mask attached
correctly? (CM-26d, CM-25d)
P.33Read “Replacing the Target Mask”, and attach
the target mask correctly.
Is proper calibration data
used?
Calibration data is written to the instrument using the
standard accessory spectrophotometer configuration
tool CM-CT1. Verify that the calibration plate is correct
for the input calibration data before performing white
calibration, gloss calibration, or user calibration.
Was white calibration
performed correctly?
P.37Read “White Calibration and Gloss Calibration” to
perform white calibration or gloss calibration properly.
Was gloss calibration
performed correctly?
Was zero calibration
performed correctly?
P.35 “Zero calibration” and perform zero calibration
properly.
