2.2 Remedies for Maintenance Requests
This section describes the remedies for maintenance requests. Maintenance requests do not effect the printer’s operation; therefore, you can continue the current printing. 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 00000108” is displayed.
As “00000108” in hexadecimal means “0000000000000000 1 0000 1 000” in binary, you can find out the code is assigned to Bit-3 and Bit-8 referring to the above table. In
this case, two errors are occurring simultaneously. (Bit-3:
Out of battery
/ Bit-8: the date/time not set.)
