Initial issue
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 ADJ 9.5 TRC Adjust (dC924) and adjust the
TRC adjustment values until output is acceptable to customer. Start the adjustment
with the settings in Table 3:
• 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
8. After completing the above procedure print a new machine system settings list using the
UI. Store this new list in tray #1 with the machine service log.
