I could argue that if the purge unit were not hampered by drying ink, the cleaning cycles might have been completely effective. But my concern is that priming a dry printhead after removing it for cleaning can take multiple attempts due to trapped air. Cleaning the capping surface of any dried...

Cone's marketing info on their pigment ink claims to use "osmosis" (read membrane microfiltration) to sort pigment particle size. This might also remove microbial contaminants. Then again, they might have microfiltered the final product. That might explain the excellent storage life.

Thanks for the info. This snippet is apparently compiled from http://www.pall.com/main/graphic-arts/ink-jet-ink-formulation-54615.page The Pall Corporation apparently markets filtration equipment to inkjet ink and inkjet printer oems. The use of such filtration technology by inkjet ink oems...

@western , You might want to do a blot test on the printhead before cleaning it. This should show that the cyan nozzles are blocked. If it doesn't, well ... http://www.printerknowledge.com/threads/canon-i960-issue-recommended-purge-unit-testing-may-not-be-adequate.4665/ post #3. You may have...

Thanks for the update. So, it sounds like the syringe filter pretty much plugged up completely when you tried to filter the bad magenta. Probably a very good thing. Did you notice any accumulated deposits in the filters with the other inks? The .22 um filters should stop anything larger than...

@western , I hope that when you write "test print" you mean "nozzle check". Trying to print ink from a clogged nozzle tends to burn out the clogged nozzle. (The boiling water in the ink nozzle keeps the nozzle temperature under control.) When you remove the head, check for a pattern of dried...

@peter D , I'd like to humbly suggest that you get your fading issue under control before trying to fix your magenta cast problem. The fading may be rapid enough to confound getting custom profiles. In any event, you probably don't want your custom profiles to be based on faded samples. I'm also...

This applies to ancient 16 bit drivers written for the likes of Win95 and DOS. It refers to 16 bit addresses, not 16 bit (colors?). You can safely ignore it.

@Gaby11 , Your partial success in alleviating the print problem suggests that the problem lies in the parts associated with the timing strip. These include the carriage encoder sensor located on the carriage, the carriage wiring harness, and the logic board(s?). (The timing strip is also called...

@Gaby11 , Did you try to clean the optical sensor in the carriage assembly as @Pentode suggested? Did you do a printhead alignment after replacing the timing strip? You didn't mention how many pages you managed print with your current printers. Do you think that you may have worn them out? I'm...

@danuk76 , have you considered the possibility that your CISS systems are worn out and need to be replaced? The back and forth movement of the carriage causes cyclic tension and compression forces on the ink tubes and associated parts. The stretched out parts could conceivably act as a pump...

Bad, bad, bad idea. The electrical components inside your printer are not waterproof The only way to reliably dry out electrical connections is to disassemble them. Spray residue may also contaminate optical sensors. Spray cleaners may also remove lubricants. If you're going to try to clean...

@peter D , Do you live close to the Taupo Volcanic Zone? Your fading problem might be due to sulfur dioxide or other volcanic gases. I see pigment inks in your future ...

I mostly agree, except what I suggested could hardly be called an invention. It may be as trivial as an ink tube holder secured to the printhead clamp assembly with mounting tape and velcro. It sounds to me like the OP wants to keep his current setup. I'd at least replace the ink tubes and the...

How about none? The glue joints would probably fail before long due the very rocking motion you are trying to prevent. There are other possibilities for air leaks besides the joints between the carts and printhead. The ink tube assembly is subjected to oscillating bending and tension loads and...

Did you have the electrical ground checked at your new location? Surge protectors are only effective if they are connected to a good ground at the outlet.

I wouldn't intentionally freeze my inks if I were you. A high quality water resistant ink treads a balance between components that are readily water soluble and components that aren't. Those components may or may not separate upon freezing or even refrigeration. They may not readily recombine on...

A minor nit on Joe's last post. It may be possible to run some pigment inks through a ,48 um filter or even a .22 um filter. I understand that some pigment manufacturers mill their pigments down to less than 100 nm in order to improve glossiness. (or at least that's how this old fart remembers...

@Samuel Laycock , Have you had any luck with Maetone? I just received my first set of OEM PGI-29 carts and cringe with sticker shock. Believe it or not, the Canon pricing is actually competitive when compared against the corresponding Epson R3000. But still, ... I'm very pleased with the...

(I'm neither a microbiologist nor an ink chemist but I'm about to play one on the Internet. Well, I spent 10 years as a professional student so I suppose that qualifies me as some sort of a general purpose expert.) I didn't mean to suggest that either heat sterilization or microfiltration be...
