Original Modes
The machine has 10 original modes. There are two text modes, three photo modes, and five
"special" modes.
The original mode key on the operation panel has two settings, text and photo. With the
default settings, the machine uses "Normal Text (Text 1)" when the Text indicator is lit, and
uses "Photo Priority (Photo 1)" when the Photo indicator is lit.
The customer can allocate different modes to the Text and Photo indicators with User Tools –
Copier Features – Image Adjustment. Note that the Text indicator does not have to be
allocated to a Text mode and the Photo key does not have to be allocated to a Photo mode.
For example, the Text indicator can be allocated to Photo 3, and the Photo indicator can be
allocated to Special 4.
If the user wishes to customize one of the original modes, the technician can change the
settings using SP 4922 to SP 4942. Refer to "SP Modes for Each Image Processing Step".
However, only one of the original modes can be customized at any one time.
SP Modes for Each Image Processing Step
The table on the next page shows which SP modes are used for each step of image
processing.
4921: Selects which original mode the settings from SP 4922 to SP 4932 will be
applied to.

fax, and scanner/printer mode with these SPs.
