General Information
GENERAL:
This bulletin is being published to provide a greater understanding of the Auto Color Calibration
(ACC) procedure. The following points must be understood prior to performing an ACC procedure:
1.
Adjustment of ACC changes gamma settings.
2.
ACC is intended to provide a "rough" adjustment or a "starting point" for the color calibration
process.
3. ACC is designed to allow a customer to automatically set gamma settings to a "reasonably
acceptable" level, however, manual adjustment of gamma settings by a Service Representative
will provide optimal copy quality.
4. In some cases, when copy quality is determined to be acceptable by the customer, ACC is not
required and should not be performed. If ACC is performed after manual adjustment of gamma
settings, the Service Representative settings will be lost if the previous settings are not selected
through ACC. Therefore, always save the Service Representative gamma settings in Permanent
memory as a back-up. For more information on Permanent and Temporary Memory, refer to the
5. The gamma settings stored in Permanent Memory for Printer Mode cannot be changed.
However, the gamma settings stored in Permanent Memory for Glass-top Copy Mode can be
changed.
6. ACC may not be required after a PM call.
7. The use of dry copy paper (~25% humidity) may result in "blasting" around text. If "blasting"
around text occurs, install fresh paper of greater than 25% humidity.
