Inkjet Printer Forum / Ink Jet Refill Forum

What about the pollutants you introduce when refilling this way? The filter is one way only, now when you refill in the opposite direction the pollutants could clog the print head.

I always fill my CLI-8 using the air hole in a vacuum. The PGI is problem because it contains a bag inside?
Where could I see come photos how PGI-9 looks dissembled?

And if you're sloppy and introduce some particulate matter, say some lint from a tissue or paper towel, I believe the intake is probably a stainless steel fritted filter, so no worries.

The fritted filter is on the printhead inlet, not the cartridge.  At least I think it's a fritted filter, based on casual examination.  I'm not about to remove a cartridge to inspect it carefully.  I believe this is needed, because if you got some fibers or other particulate matter on the exterior of the cartridge outlet, you would not want it to pass through the head.  It's all pretty well protected, I think, unless perhaps someone is quite careless about dirt.

As the cartridge empties, there is no air left inside the bag, it collapses. So if you put the cartridge under a vacuum, there is no air to expand before and after vacuum. That means that the vacuum process will not work.

The only way for the vacuum to work with this cartridge, is to re expand the bag, somehow, hold the bag expanded,, submerge the inlet in ink and then cycle the vacuum process. This is far too much work for alternative simpler processes that will work equally well, if not better.

I just read like you do on this forum years ago that refilling through the inlet port is a mistake, you have to keep ink flowing in one direction only. Since PGI-9 is a bag cartridge why don't you seal the inlet port and refill using air hole under vacuum?

I used to argue this point many years ago when I was vacuum filling through the air vent on BCI type cartridges. I also was concerned that the filter in what I call the outlet port (I think it is what you are calling the inlet port) could not tolerate a high flow rate of ink. These still may be valid concerns but I've grown weary of worrying about such things and I violate my own previous recommendations, just because it's easier to fill using my Freedom method through the outlet port. Maybe some day I'll regret it.

EDIT: I guess I gave up on my concern because of the cartridge purging technique that forced water under pressure backwards up through the outlet port filter.
