Display Content
In SIM44-36, the toner
patch density is read by
three kinds of LED
currents with the primary
LED current adjustment
value as the center value
in order to obtain PCS C
LED ADJ value. This is
the deflection range of
the current value in the
above case. (Color image

Operation test/check
Used to forcibly execute the image forming section
correction (high density process correction) (process
correction).
Process (Photoconductor, developing, transfer,
cleaning)
Operation
1. Press the [EXECUTE] key, and the image
forming section correction is started.
Correction is normally completed.
An error occurred during correction.
(The previous correction result is
maintained.)
