Thanks for the info. I guess I misunderstood the purpose of those clamps. I thought you were filling the cartridges, re-clamping the feed lines and isolating the cartridges, resetting the chips. Then they should behave as normal cartridge. That would work unless I'm not understanding the process clearly.

Hadn't thought about that but no I wouldn't recommend using it like that, mainly because there's always a certain amount of air gets in the cartridges and if you locked off the clamp air would eventually find it's way to the printhead as it ran out.

Anyhow, looking forward to your final results - Jack

I'll PM them to you... It's a bit awkward but I'm a little miffed that I had to do all the testing to work out the chips would work and the supplier wouldn't actually compensate me for the ink, time, etc... I have to put in to find out myself. So I'm not about to publish the results for them to use for nought.

Hey Martin, sorry that I have gotten back to you, but I was relying on my email notifying me of thread responses and apparently. I know I must have gotten it, but somehow missed it.

I understand what you mean by air getting into the system. I sometimes joke about how physics always seem to get in the way sometimes. I went ahead and replaced my black cartridge with a HP 88XL size for the moment, so I have time. I know it doesn't matter for a CIS system, but are the auto-reset chips made for standard or XL size cartridges?

Also, We won't have to pull the cartridges out of the printer to reset them, correct? Anyhow, let me know when your finished testing.

Thanks - Jack

You can get both types of chip... Needless to say because I'm planning on using them with a CIS the XL/High-capacity chips are the ones I've got coming (later today as it happens).

Testing was completed a few days back now. There was some good news and some bad.

The good is that you can reset the chips enough that they will continue to work with the K8600.

The bad news however is that the printer is not recognising them as "originals" so you end up with a couple of work-arounds you need to do.
1. To reset an "empty" cartridge you need to:

Wait until the cartridge is really reported as faulty and/or empty
Open the cartridge bay door
Pull the cartridge out by an inch or so (to allow it to disconnect the chip from the printer)
Turn off the power
Push the cartridge back in
Turn on the power again

2. Once you've done that reset it will recognise the printer doesn't have a valid HP cartridge but will continue to print.. However it will disable the ink monitor for that cartridge
3. If you ever lift the printer lid to clear a paper jam you'll need to turn the printer off and then on again to get it working because it trips something that creates an error for all your colour cartridges. The power cycle clears this easily enough though.

Obviously this isn't ideal but it's workable and with a CIS it's fine... I've kept the supplier aware of the issues and my ink supplier is following another possible source so I should be getting some alternative samples in the next month if all goes well.

Good info on resetting both cartridge sizes. Apparently the cartridges that come with the printer are a hybrid size that's a bit larger than the standard size. The large have the advantage in that I could simply refill the XLs and that would delay me getting around to the CIS solution.

Currently my black cartridge's chip reported that it ran out of ink and I'm using the Image Specialists ink I refilled it with. It's all new to me and I didn't know what it was going to do when it ran out completely.

I'm assuming the the color cartridges will behave differently and the printer will stop printing when their smart chips say they are out. Is that right? Otherwise I could just use my current cartridges that came with the printer in my DIY CIS system.

I agree with you that the reset process isn't ideal. Hopefully you'll find better reset chips, but if a good chip isn't available yet we'll have to make do.

The XL cartridges (especially the black) are good value for money so for less frequent printers they're a good option.

So, you refilled and then just plugged it back in? or have you been able to handle a reset?

It depends on the kind of chips you have...

There are dependent chips where the colour chips all rely on the black chip to handle resetting, or the independent/individual ones that will work regardless of the black chip status.. The latter tend to be more expensive. If you have the dependent ones they will act differently but to date I've found 4 different chip types all reacting differently to different printers and different situations... Documenting them makes my head spin.

I'm starting to have my doubts... the way things are going is making it look more and more like the best you can hope for are chips that basically refuse to reset, get marked as non-HP but allow the printer to continue to print. That's a more realistic goal and one I'm hoping to pursue.
