Dspl prmry trns current(Bk):full clr mod
To display the decuple value of the current flown to the Primary Transfer Roller (Bk) by the primary
transfer ATVC control in full color mode.
When the two values are out of the target value range (50 to 700), clear the log information for the
appropriate control (COPIER> FUNCTION> CLEAR> 1TR-CLR).
If the two values are both small, the Primary Transfer Roller may have reached the end of life.
