3.5 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 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.)
Note *1: This call occurs only to Epson Stylus Pro 7900/7910/9900/9910/WT7900/WT7910/9890/9908/7890/7908.
