Changing back up battery in Canon MP830 fax/printer

[Gel]

This unit is few years old and the fax doesn't retain it's date etc.
Anyone ever attempted fitting new back up battery?

I guess it wouldn't be a simple disc type as used in PC Towers

There might not be a battery. If there is, you should find a cover for
it somewhere. There might be a single screw holding the cover. I would
expect it to be something like a quarter-sized disk lithium cell.

According to Canon, the printer gets its date from your computer if the
"MP Drivers" are installed.

Interesting!

It is certainly true that (all?) the PIXMA/PIXUS, and many of the BJC
and other series receive the date & time from the computer as part of
the printjob, in fact in the first line of the printjob data, which when
parsed looks like this (this is the start of a MP830 printjob taken
earlier this year, on plain media (A4 paper size) using highest-quality
printing). As you can see, the time is set in the initial control block:

------- parsing the printjob -------
ESC [K go to command mode
BJLSTART
ControlMode=Common
SetTime=20110405115630
BJLEND
ESC [K go to command mode
BJLSTART
ControlMode=Common
SetSilent=OFF
BJLEND
ESC [K go to command mode
BJLSTART
ControlMode=Common
PEdgeDetection=ON
BJLEND
ESC [K reset printer
ESC (r printer specific command (len=1): 0x64
ESC (b set data compression (len=1): 1
ESC (c set media (len=3):
model id 3 bw 0 media 0 direction 0 quality 3
ESC (d set raster resolution (len=4): 600 x 600
....
