Magenta problems Pro9500

[mikling]

A cool place is always better because it slows down chemical breakdown which is always happening. So the coolest place short of a refrigerator is probably ideal.

The other thing is that I would actually stick with 2oz squeeze bottles for Canon pigment as it is becoming clear that these Canon pigment printers are more sensitive to pigment ink physical properties than previously thought. With the smaller bottles there is less air volume for the ink to vaporize into and become thicker so it will slow it down.

The above photo I previously submitted is what happens when you attempt to use ink with the properties of the 9500 in the Pro-10. Ink delivery issues. It gets worse if you use PGI-9 carts. indicating that the internal properties of the spring might have shifted as well. This necessitated a totally new inkset for the Pro-10 from the ground up and hence the delay in the inks for that printer. Since I am funding the development, those new inks to be made by IS will be exclusive to myself.

Rod I would like to obtain the old ink. Please check your PM.

I wouldn’t have taught the ink would have been a major contributor to this print problem unless it was not shaken before use or stored constantly above 25 Celsius, so my money is still on the cartridge because it hasn’t been ruled out yet.

When you bought the new Magenta cartridge you only half solve the current issue, you still don’t know for sure what exactly caused the print problem, was it the Ink/Cartridge ? So because of the uncertainty this same issue can easily manifest itself again.

In all the time I’ve had the 9500 I've never had a clog in the print head, I still have some ink that’s over 4 years old and the only print problems that I‘ve had were directly related to the cartridges, I was to ignorant to think the cartridges could actually possibly clog up..

Hi Rodbam,

Why are you using those paper spilling large patches for your Colormunki profiles? You can print 4 targets on a single sheet, which saves paper and ink .

Thanks Mike, Hat & Pharmacist. Yes I remember how you printed four patches on one sheet & used a ruler to guide the munki.I will have to try it one day.
Hat, don't forget that I tried two different cartridges before buying the OEM so my money is on the ink but who knows. The daytime temps here in Brisbane are 30c up to 40c in summer & normally 20c to 25c in winter so it would be a bit hotter in the west facing room where I store my ink.

Wow!... Ok, that'd do it...

You may have to remove a tinny or two from the beer fridge and pop your inks in there to keep them cooler. No need to remove the bulb in the fridge though, unless of course, you're using a UV bulb to top up your tan each time you get a beer

It would be unaustralian to make room in the beer fridge but our east facing garage stays a lot cooler than anywhere in the house so I might store the inks in there.
I will leave the light in the fridge so I can see my look of anticipation reflected in the bottle I'm reaching for

Well it looks like I owe The Hat a beer, I put my money on the ink being bad causing my strange looking magenta problems because I couldn't believe both magenta carts going bad on me. I have now received my new ink from Precision Colors & the problem remains with both old cartridges, so even with the high storage temps down here the ink must still bOK. The final proof of everything will be when I refill my new OEM cart with IS ink after the OEM ink has run out.
My carts would have only been refilled 10 or less times so does this suggest they have a short life? I also wonder if I'm overfilling them because the new OEM carts weigh just over 30g & I have been refilling to 31g to 32g.
The Colormunki patches are not improved with the new ink in the old cart but the nozzle check looks a bit better but it still has a magenta bleed off the vertical black lines.

Any follow up on this Rod?

Always curious to see how things progressed (or didn't)... Hoping for the former naturally!

Gday Martin, It looks like both my Pgi9 cartridges were at fault. The new Canon magenta cart has been refilled twice with no problems. I don't know if I damaged the spring mechanisms in the old carts when cleaning & flushing them out, the outlet sponges on both have lost that grid or honeycomb pattern on the surface from forcing water through them when cleaning but I wouldn't have thought that would cause problems.
I'm getting some great looking colour prints with the 9500 pigment inks on Kodak metallic paper, I can't see any gimmicky metallic look but the bronzing/gloss differential is very minimal for such a glossy paper.

Thanks for the update Rod... I guess the lesson in this is not to assume that lightening can't strike twice so worth keeping in mind.

Might add a "watch out" to the flushing process in case that's the vector here, although thankfully flushing shouldn't be required in most cases...

Did you flush out other cartridges/colours as well btw?
