3. X-Rite Spectrophotometer Calibration
The X-Rite Spectrophotometer can be adjusted to its original accuracy
by calibrating it once a year. Calibration may be required when
calibration results exceed ∆E≤ 2.0 , or when there is a sudden shift of
∆E1.5 or more from the previous measurement.
Calibration may also be required after unsuccessful attempts to clean
the calibration white tile.
Spectrophotometer Color Sensor's measurable range has been
exceeded, and a "Sensor Error" message is displayed on the printer.
Canon recommends that an annual calibration of the X-Rite sensor be
performed in order to confirm its default value. When requesting
calibration, the authorized servicer, or end user, must contact the
Canon CITS hotline at 1-800-423-2366 to arrange for shipment of the
X-Rite Spectrophotometer Color Sensor and Calibration White Tile to
Canon. CITS will arrange for the X-Rite Spectrophotometer Color
Sensor and Calibration White Tile to be shipped to Canon. Within ten
(10) weeks, the calibrated items will be returned to the sender.
4. X-Rite Spectrophotometer Certificate of Conformance
The X-Rite Spectrophotometer is bundled with a Calibration Certificate
of Performance to confirm the measured accuracy of the X-Rite
Spectrophotometer Color Sensor calibration during the warranty period
and after subsequent calibrations. Canon USA recommends that the
installation date of the Spectrophotometer and other items are recorded
on the certificate.
