How much soaking liquid?

[flippin]

Hello all, Many thanks for the vast amount of information which has been shared here. I have several Canon printers i850, i9100 and I recently purchased an almost new i9900. Unfortunately despite the amazingly new-like condition of the i9900, it has sat for a couple of years unused. The carriage had 4 cartridges with ink and the other spots were vacant. No surprise, there is a stubborn clogging issue. I have attempted to read through as many posts in the interests of not embarrassing myself asking for information which has already been posted yet I have been unsuccessful in my quest. I have some experience cleaning the heads with the various concoctions posted here and elsewhere but my question is how much solution do you use to soak a printhead. Should the fluid level exceed the electrical contacts on the back of the printhead module or do you only use enough to "wet" the actual heads on the bottom of the part. If there is no damage anticipated from an almost complete submersion, I could see some benefits in also soaking the screens.


Many thanks in advance for your answers to my question about submerging the entire printhead.

Cheers

You may receive every answer imaginable. There is no one way. I think most would advocate that the screens of the print head that are adjacent to the inserted cartridge need to have fluid introduced in some manner, whether it be squirting liquid into them with a syringe, a stream of water from a faucet, or submerged in solution. I have had no issues with completely submerging all electronic areas of the print head with whatever solution I was using. I also blew out the print head with compressed air and let it dry completely before placing it back in the printer.

Others have postulated or maybe even had a problem caused by full submersion, but these are few and far between reports. Obviously there is a risk using chemicals that might be harmful to the electronics, so think before using exotic concoctions. Water with high mineral content might be an issue, but you could rinse with distilled water after the soak to remove potential electrical conductants.

Recently, there were a few posts about people's flushing practices. Search around in threads form the last week or so to find them.

Thank you for your reply. I had also included a detailed description of my flushing practises complete with photos but given my newbie status I am not currently allowed to post pictures. I will share them once I have achieved the privilege of posting images.

Thanks again.
