My IP 4200 Cannon printer shows both black cartridges CLI 5 & CLI8 as
being empty although both are still 3/4 full.
The black is hardly ever used because i only use this printer for
color
photos. What can i do ?

How do you know the cartridges are 3/4 full? If you remove one of the
cartridges you will see it consists of two compartments, one of them
is foam
filled and one has only ink in it. If the one that is not foam filled
is empty
then the cartridge is empty regardless of the amount of ink in the
foam filled
compartment.
Even if you don't print text the large cartridge will be used up
during
automatic routine head cleaning cycles and the small black is used in
photos
added to the other colours to make up the correct colour composition.

The one not foam filled are both 3/4 full.


Well there is something amiss. The way the printer knows when the
cartridge is
empty is by using a prism (part of the cartridge) and it physically
detects the
ink is firstly "low" and then "empty". The chip on the cartridge is in
addition
to this and I guess you are using OEM inks otherwise the printer would not
report ink levels at all.
The only way you are going to find out is to replace one of the cartridges
that
is reported as empty.

I have read a few posts of these printers misreading the chipped OEM
cartridges. Canon's brilliant move to try to thwart refilling has backfired
in some cases! I don't know if it was the cart/chip that was defective or
if it was the printer. As Tony said, you will find out if you change the
cart.
