3.1 PC Loading upon Memory Error Occurrence
3.1.1 Explanation on Procedure
The PC loading procedure when the LCD on the MFP displays “MEMORY ERROR” for a hash
NG state due to one reason or another is explained below.
(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 proce-
dure from step 2 after turning the MFP power off once and to on again.
