Replacing the Backup Battery
If the backup battery is dead, the printer’s date and time cannot be retained.
Follow the procedure described below to replace the backup battery.
Note
It’s very important to protect the printer controller board and any
associated circuit boards from electrostatic damage. Before performing
this procedure, review the antistatic caution on page 226. In addition,
always handle circuit boards by the edges only.
