I have has this problem from day one on a 932c printer and I finally got around to write to HP about it. They responded and acknowledge the problem in the e-mail with a link to a document on this issue:

Also here is the text that was sent back:
 
According to your e-mails, there is ink in the capping station of your
HP Deskjet 932C printer and you believe that the ink from the cartridges
is leaking into the capping station.
 
It is normal for a little ink to be present in the capping station or
the small rectangle containing absorbent material at the home position.
There are multiple uses of the capping station. Some of these uses are:
 
1. Cleaning the nozzles.
This will clear any dust particles that may have been stuck on the
nozzles during the printing process.
 
2. Cleaning excessive ink.
The often times excessive ink may be sprayed and some of it will
remain at the nozzles and may cause ink smearing. The absorbent
material will absorb this excessive ink and keep the nozzles clean.
Hence, the ink being observed in the capping station.
 
3. The wet material in the capping station caps the nozzles and
prevents the ink from drying at the nozzles.
 
This "little ink" would be a mountain if I havving been cleaning it everytime I refill the cartridges! As far as I am concerned it is a real problem, probably due to their 'negitive pressure' black cartridge design.
 
I haven't seen any other posts anywhere on this and I can't believe no one else has brought this up. I estamate at least 25% of the ink is wasted just dripping out! Of course HP is feverishly working on the problem since they have to sell more cartridges to make up for the wasted ink!................
 
How many others see this and what are your opinons on this? BTW, this is even with HP cartridges, not just refills!
