3. When [NEXT] key is pressed repeatedly, the display changes
from Coefficient to Reference Value then to Correction Value in
this sequence.
• When the displayed item is not yet executed, "-" is displayed. In
case of an error, "ERR" is displayed.
• For the reference value and the correction value, an error
display is not made, but the previous value is displayed.
3. Enter the set value with the 10-key and press the [OK] key to
store the set value.
Note: Do not set to other value than the default.

∗
In the case of abnormal completion, ERROR is displayed and
the correction data are not stored.

Purpose Adjustment/Setting/Operation data output, check
(display, print)
Function
(Purpose) Used to check each color toner patch image density
UITU in half tone image forming section correction
(process correction). (This simulation allows to
check if correction operation is performed normally.)
Section Process (Photoconductor, developing, transfer,
cleaning)
Item Data Operation data (Machine conditions)
Operation/
Procedure The toner image patch density data in half-tone
correction are displayed.
[1ST STEP]: The toner image patch density
sampling data in the 1ST STEP are displayed.
[2ND STEP]: The toner image patch density
sampling data in the 2ND STEP are displayed.
