Replacing the Backup Battery
When the backup battery is at its end of life, the printer’s date and time can-
not be retained. Follow the procedure described below to replace the backup 
battery.
Note
Only use the coin-shaped 3V lithium battery CR2032. 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 219. In addition, always handle circuit 
boards by the edges only.
1Turn off the printer and discon-
nect the power cord and inter-
face cables.
