7. Perform an Auto Gradation for Copy-Text, Copy-Photo, Print-Text and Print-Photo (For
DC3535, Copy Text, Copy-Photo, Print, Network Controller 1). Check for the following:
• Prints improved but copies did not - adjust Color Balance as described in step 6
above
• Copies improved but prints did not - Recheck all print driver settings. Calibrate the
controller (Auto Gradation, Auto-Cal, Color Wise Pro Tools).
• If both modes are still too light, go to
TRC adjustment values until output is acceptable to customer. Start the adjustment
with the settings in Table 3:
Table 3 TRC Settings
Low
Y: 128
M: 128
C: 128
K: 128
• Adjustment to dC924 will affect copies and prints. Check output of the prints and
copies in Photo modes; if the output is too dark, perform a Print-Text, Print-Photo,
and / or Copy-Photo Auto Gradation adjustment. (DC3535 perform Copy-Photo,
Print, Network Controller1)
NOTE: Performing a Copy-Text Auto Gradation will automatically reset the dc924
TRC adjustments for the walk-up mode copies back to 128. If an Auto Gradation is
performed after this point, the output prints and/or copies may be perceived "light" in
densities. Please instruct customer not to perform a Copy-Text Auto Gradation
adjustment, or disable the Copy mode (Copy-Text and Copy-Photo) Auto Gradation
LUTs by setting NVM 701-929 = 0
