Servicing Canon i850
 

Anyone know how to get the i850 apart ? ..
no obvious screws.
....mines in need of a good clean , dust and ink.

The printer is held together with molded plastic clips that are part
of the casing.

Look closely at the back and sides, and you'll notice four little
slots with arrows above them. Use a small screwdriver to GENTLY push
into the slots and push the little plastic clips back. This will let
you lift up a bit on the top casing, but you can't remove it just yet
so don't lift too much.

Now while the top casing is loose, lift it a bit and gently pry the
two white plastic trim pieces on the sides away from the casing. You
can't do this until you loosen the top though. Then gently push the
side pieces towards the front and out to release them from the side
casing.

Now use the screwdriver in the two front slots that were hidden by the
white trim pieces, and the top casing will come off quite easily.

If you apply power, the printhead assembly will move to the center,
and you can then clean around the parking station.

Brilliant, thanks Bill. easy when you know how.
Is it normal for the reservoir waste pad at the bottom to be saturated
with ink ? can't see a way to access it so just mopped up excess ink
by pushing some tissues down the gaps.

I don't recommend it to others, but if you're mechanically inclined, it
is quite possible to remove the entire printer mechanism and clean up
the waste ink area. Although it's not really necessary since the ink
dries and settles into the padding, and there is no sensor there to
govern the waste ink volume. It's a messy job too.

If you want to brave the procedure, let me know and I'll post more
details, but remember that it's not at all necessary.

Bill,

I'd love the details - I think the waste area might the cause of my ink
tank contamination problem (I just made a posting describing the problem
in detail).

Thanks,

Mike

A 'Waste Ink' pad even if it did need replacing would not cause
cross-contamination of your tanks. This printer will also give a waste ink
warning indication when the pad needs service. Generally this is several
years of average use before this happens.

Your issue would more likely be bad ink, bad printhead, or encoder issue
causing the head not to park in the proper area over the purge station.
