Canon Yellow issue re: OctoInkjet stock

[mikling]

On this side, the initial problem when diagnosed was solved. I am totally free of these issues now since mid June 2011. ( my C0797D yellow was not affected and my 221yD ink is free of this issue as well .. ) I am no longer getting any issues and the methods I outlined have been 100% effective so far including the flushing of the cartridges when it occurs.

If the reaction occurs the first stage is that the viscosity increases. This has two effects. It will bind itself to the sponges very well. The second effect is that the porosity of the filter on the printhead is very low. This filter below the mesh essentially will block the new ink from entering the head because of the increased viscosity. So as soon as we break up the ink in the affected area, and extract it, the printhead is then good again. As for the cartridges, the recommended solution is best left in the cartridge overnight before flushing. The outlet felt in the cartridges is also of low porosity and will hold the affected ink very well too. Use the recommended solution of automatic dishwashing detergent to clear that up as well. Alcohol and Windex is not effective at all. The printhead should be flushed after using the Cascade dishwashing formula.

Once these steps are followed, the problem is resolved.

Thanks for the information Mike... Piecing together this puzzle is fairly tricky so I need to wait until a couple of clogged heads arrive here for me to check over and then test clean...

Interesting also about the OCP inks... That's going to be a whole other problem but certainly doesn't sound good if the supplier won't even get back to you.

I've just received 100ml of WJ797 yellow from Octoinkjet this week. As it happens I have only used it so far to top up a Durchstich'd-refilled OEM CLI-521Y cart (i.e. ink source unknown) after replacing a QY6-0072 print head that jammed after 12 months using ARC'd refillable carts.

I was going to use this ink to refill empty OEM CLI-521Y carts won at auction but if your latest batch of WJ797 may be affected by this problem what cart-purging method do you recommend? Will flushing with warm Still Table Water through the top filling hole until clear be enough? What drying methods do you recommend - how about storing the carts overnight in a cardboard box with a couple of hot water bottles?

Incidentally, with reference to your notes about purging carts before changing inks how does this affect the advice to use CLI-521C (IS ink WJ244) carts instead of trying to refill opaque CLI-526C (IS ink 2032) carts?

If you could PM me the batch reference I can give you a definitive answer as to whether it falls within a potential problem batch. My guess is that it's not but it'd be nice to confirm.

There's a couple of posts on the forums that pull together all the available methods for purging and drying so I'll list those here:

Flushing through the top fill hole will definitely work better, or rather quicker than most other methods although patience seems to be the key ingredient to getting the others done...

It doesn't... No other inks are affected and beyond wanting to avoid potential colour differences or similar from mixing inks you shouldn't have any problems...

The Full Set Flusher - as promised.

Just in case the pictures failed to explain, here's the instructions for the Full Set Flusher.

1. Starting with your set of carts to be flushed, drill the top filling holes , starting with the gimlet and finishing with the screw itself
2. Then create the die in the steel plate using the same gimlet and screw size.
3. Now create the 35mm spigots making sure that only the sizes that are tight in the die are used.
4, Place the required number of pierced Fat Plugs, flange side inside, in the holes in the reservoir, taking care not to split the plastic.
5. Seal any remaining holes with unpierced plugs.
6. Screw the spigots into the cartridge filling holes, making sure they are tightly in yet not so far in that they press against the bottom of the cart.,
7. Now coax the protruding ends of the spigots into the reservoir through the pierced Fat Plugs. (Note how using a slightly smaller drill than the actual plug size makes everything watertight).
8. Place the 50pc lid the right way up in the waste bowl. (Note that this lid should be pierced to allow waste to flow under it).
9. Place the reservoir on top of the 50pc lid so that the carts rest against its sides.
10. Now fill the reservoir with warm, clean water and ensure that waste is flowing from the output nozzles of all the carts and has not stuck because of a loose or blocked or bent spigot.
11. Keeping the waste bowl emptied; continue refilling the reservoir until the waste is clear.
12. Carry out your chosen procedure for drying out the carts.

Per post #15

I would like to complete the name to The Full Set Flusher: The OMG!!!* Full Set Flusher!!!!!!!

My thoughts:

1. I cannot image the stress level if you have only one printer and you have to flush using this system. Please get a back-up printer!!!!!!!!!!

2. Vise grips?!?! Hand drill?!?!?! Screws?!?!?! Are you working on an ancient clothes washer????? No, you are working on carts. Do you intend to refill the carts after you have installed the screws??? If the answer is yes, than you will have leaks**. Please replace the screws with silicone plugs or hot glue plugs. Hopefully the holes made for the screws are not too big for the silicone plugs. If the holes are too big for the plugs you will have to use the hot glue plugs. If you can use the silicone plugs please see if you need the regular cap plugs or the low cut cap plugs. The low cut cap plugs are for printers that have clearance problems.

In my mind using screws is like what they say about concretecrack or will crack. With screws it isleak or will leak!!!! Every time you remove a screw for flushing or refilling you are wearing down the opening/threads. Eventually you will have a leak(s).

3. How many holes do you make in each cart? It is hard to follow your instructions to see how many holes you make in each cart. You should make no more than two holesone hole if you are using the top-fill method and two holes if you are using the german method. In short, more holes, more leaks!!!!!

Thank you.
