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.

from electrostatic damage. Before performing this procedure, review
the antistatic caution “Antistatic Protection” on page 201. In addition,
always handle circuit boards by the edges only.

Turn off the printer and discon-
nect the power cord and inter-
face cables.

Using a coin, remove the screw.
Then, remove the left cover.
