2.5.5 Performing a Density Reproduction Check
NOTE:
Performing this step is a verification method for step “Performing a Density
Reproduction CheckCalibration”. If the Density Reproduction Check is successful, the
internal densitometer calibration is OK.
(1) In the browser pages select menu "Service Engineer Tools - Enter Service
Command Session - 3 Print Image - 1 Test Image".
(2) Select the upper or lower tray.
(3) Print out LinCheck.zip and measure the density of the eleven 100 % to 0% fields
with a calibrated MacBeth TR-924, X-Rite 331, 341, X-Rite 301, X-Rite 310 or
Gretag D200-2 densitometer.
(4) To check linearity fill in measured values in the density reproduction check Excel
file. See Figure 16.

(5) After the measured values are filled in, the density reproduction is calculated
automatically.
At the right hand side of the table is shown, whether the Density
Reproduction is ok or not. In case it is not ok you are requested to carry out a
CDM calibration.
