HP Officejet Pro 6835 6230 6830 6812 6815 6820 CIS Install 934/935

[@demented12]

I went to every link in your site, and couldn't find this CIS, very confusing.

So i kinda have the same setup its a 6978 with the 902 cartridges though, so with the cis system and that type of cartridge and printer, you have the feed line to the tank to the cartridge, and what about the cartridge vents? Do you need to air tight the cartridge for the cis setup?

Just a thought: During installation it might be helpful to place the ink tanks on the floor so that its lower than the cartridges. You might get less backflow during installation because you've eliminated downward pressure from gravity.

That's a great idea! Thanks Devvyn! =]

How do you get the ink into the cartridge at first

[@eclipse5393]

I bought mine off ebay. I also used a Dremel to clear out extra plastic guards that were in the way and make a slot on the side for the tubes. Now I can close the printer. My printer is HP c309a.

What cartridge did you use on that, Sir? My printer is an HP Officejet 6820 and my cartridge should be 934/935 same as the one you have. It seems that the cartridge you used on the video is a refillable cartridge 564/920 type. Can I also use that one? Please reply ASAP. Thank you. Have a nice day
