I wonder if we approach this issue of long term non-use of the printer like a denture when out of the mouth. Take the cartridges out, remove the print head, place the print head in a container that can be sealed that has enough liquid to cover the ink inlets. The liquid can be pharmacist's solution or a constituent(s) of that solution. The idea is to recreate similar conditions and fluid Canon uses when they pack and ship a new sealed print head.

While this may waste ink when you reassemble the print head and cartridges back in the printer, at least your print head may remain viable.

As i may not be able to print everyweek i am going to give this method a go.
I've bought a few extra heads, but really think this advice may be worth a try instead of burning thru spares.
Once i run through this i'll report back..........thx

I don't know if it will work but I appreciate your willingness to try.

The following are recipe's for Pharmacist's Solution as well as substitutes for the various ingredients:

Pharmacist's cartridge flush solution recipe:

-3 % propylene glycol (or 2 % glycerin)
-20 % isopropyl alcohol
-distilled water up to 100 %


========================================================================


Substitutions For Pharmacist's Solution

Propypelene glycol can be substituted with glycerol (100%) or glycerine (70% glycerol mixed with water). Isopropyl alcohol can be substituted with normal alcohol (ethanol).

Formula Substitutes:

Denaturated Ethanol/Alcohol 96% (denaturated with 3% ether) 20 parts
glycerol 2 parts or glycerine 3 parts (reason: glycerine is slightly diluted glycerol)
concentrated ammonia 1 part
distilled water up to 100 parts

I have just noticed something similar to that shown in image #5 in post #21. It was found in the ink reservoir. I noticed it in the CLI-8BK cartridge from this post after flushing and reconditioning. I noticed this small thing around 2.5 mm or 0.1" in length when I attached a piece of kitchen paper to the ink outlet to dry the cartridge.

Using a USB inspection camera, I shot this image through the refill hole:

I managed to make the thing stick to a wooden cocktail stick, so I could remove and scan it. Here is a 1200 dpi scan, the thing broke into two when I removed it from the cartridge:

The cartridge appeared to never having been refilled, but the the history and age of the cartridge is unknown, as it is from a salvaged printer.

All of them! LOL
Ear Wax?

Sorry, seriously that is really strange though it looks fibrous to me. But what it might be is a good question.

At the risk of attracting attention from the NSA...

We have to collect and store our own water on the farm as we are not connected to a water supply system. Contaminated water is to be avoided so we installed water filters that extract masses of junk that end up suspended in our water in storage. As a result of the quantity and appearanceof the 'floaties' appearing in the water we installed similar water filtration in our home in the City too........Shock horror!!! there is as much floatig junk collected from the City supply as we extract from our stored rain water.

We were truly shocked at the volume of particles removed from the domestic water supply system, the Authorities assure us its normal and safe?

Isn't that what Aussies call "flavor"? :eek:

You're getting soft, 3puppies! Dysentery is a national pastime in the Outback. :sick Buck up, man! :gig

Honestly, that sounds disgusting. Filters sound like a smart choice.

Yesterday I cleaned some PGI-520/CLI-521 cartridges to restore full capacity before refill. I can normally get the ink outlet and what can be seen of the sponges white by using 200 ml of de-mineralized water and Octoinkjet's flusher. One magenta cartridge was not properly clean after this flushing, so I filled the cartridge with pharmacist's cleaning solution using the flusher for a Freedom fill. I then noticed some magenta debris floating around in the ink chamber. I think this cartridge should not be reused.

Here is a scan of the debris, it looks similar to that in post #21:

And here is the not so clean ink outlet:

I don't know if this is of biological or chemical origin, the cartridge had been run almost dry so maybe this is formed by evaporation of water and solvents?
