3.2 PC Loading by Manual Operation
3.2.1 Explanation on Procedure
Loading shall be performed as shown below when the PC loading function is selected by key operation
by a service man.
(1) Activate the MS(PC)-DOS with the host PC and the MFP connected via the Centro cable.
(2) Input the copy command from the MS(PC)-DOS on the PC to output the loading data file in binary
specification to the LPT1 in order to transfer the loading data to the MFP.
Example:
>copy/b xxx.x LPT1
(xxx.x is the loading data file name.)
(3) The user shall judge the normal end of data loading by checking the normal end of file output on
the PC and sounding of the buzzer indicating the normal end on the MFP. If the MFP displays
an error on the LCD, sounds the buzzer for an error or lights up the alarm LED, the user shall
judge abnormal end of data loading from the PC and repeat the procedure from step 2 after
turning the MFP power off once and to on again. (See “6. List of Error Causes and Corresponding
Codes” for the error cause.)
