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 00001800” is displayed.
As “00001800” in hexadecimal means “000000000000 11 00000000000” in binary, you can find out the code is assigned to Bit-11 and Bit-12 referring to the above table. In
this case, two errors are occurring simultaneously. (Bit-11: out of battery/ Bit-12: the date/time not set.)
