Spectrocam TIPs and Troubleshooting
Calibrating the Spectocam
Color critical jobs should have each media calibrated separately using the
recommended Xerox media. If the user checks the “Apply this calibration to
all media types,” the same calibration will be applied to all supported media
types. This is not recommended for users with color critical jobs.
all media types,” the same calibration will be applied to all supported media
types. This is not recommended for users with color critical jobs.
Make sure the Spectrocam is calibrated with the white target reference that
was shipped with your Spectrocam. The serial numbers on the bottom of the
white target reference target and the Spectrocam must match. Setting the
white target reference target and the Spectrocam must match. Setting the
white reference to a different target can result in inaccurate printed color.
When measuring on the white target reference, be sure the device is seated
correctly.
Scanning the Test Form
Make sure the printed test form is properly aligned to the black scan plate.
The Spectrocam must start inside the first patch directly in the center.
Otherwise, patches will be read incorrectly.
Otherwise, patches will be read incorrectly.
Make sure the Spectrocam is securely seated in the guide ruler and not tipped
while you read patches. Tipping or miss-aligning the Spectrocam while on the
guide ruler will cause errors.
The green sensor on top of the Spectrocam responds to transitions from light
to dark. The sensor must be activated to measure each row. Inadvertently
covering the sensor can prematurely initiate the measurement sequence.
Listen for the flashlamp before you move off the first patch. Sometimes there
is a slight delay before it begins to measure.
Reading patches too rapidly is a common error. Scanning one row should take
about 6 to 8 seconds.
