MAINTENANCE REQUEST XXXX
When a Maintenance Request error occurs, the printer displays on the LCD a hexadecimal code of “NNNN” which correspond to the bit numbers assigned to error statuses as shown
in the table below.
NOTE : Ex): When “Maintenance Request 0088” is displayed.
As “0088” in hexadecimal means “1000 1000” in binary, you can find out the code is assigned to Bit-3 and Bit-7 referring to the above table. In this case, two
errors are occurring simultaneously. (Bit-3: battery exhaustion/ Bit-7: the date and time has not been set.)
