Could anyone suggest why the Status Monitor of my Canon ip4000 does not
show the current ink level? It always shows all the tanks as full. The
printer is not very old and the ink tanks are the original ones supplied
with the printer, some are more than half empty.

Cheer up. There's nothing wrong with your printer or the ink level it
shows. The printer will only show you the following settings - Full -
Low and Empty. In other words, the "meter" won't move until the sensor
senses that your ink level is "low". I know, it's a big step from "full"
to "low", but Canon has decided on this rather primitive method. It does
work rather well. Since I refill the cartridges myself, I change all the
color ones as soon as any one indicates low. That way all 4 start at the
same point and I don't have to stop every few minutes/hours to change
another cartridge separately. The large black is twice the size so it's
changed independently. Hope this helps! . . .

Canon employs the better than not having a sensor at all approach.

The above link is to a nice illistration of the technology. Basicly it
uses a prism, when the reservoir is 100% empty the sensor is triggered,
but you still have 20% of ink in the sponge. This should cover 5 full
pages of color text, or there and abouts of 100 pages of text.

Given that a 1/2 empty reservoir when taking into account 20% of ink
is in the sponge side, your really at 60%. 1/4 full and your really at
40%.

Thanks! I am happier now. It would have been a real pain to have to
return the printer for repair.

THAT IS WHAT THEY HAVE MANUALS FOR

THAT IS PROBABLY THE CASE BECAUSE OF AFTERMARKT INK
