So why? Why should one color be the biggest problem? Perhaps the formulation of Canon's cyan for CLI-8 cartridges is different in some property or properties that makes it more subject to some form of clogging. What do you know? Here is what happens: With my CIS primed and doing fine nozzle...

Both Refillers and CIS users may make use of these plastic syringes. After a time, they seem to degrade somehow, becoming sticky or difficult to operate, with distinctly greater operating friction. I know that I should just trash the syringe that becomes a drag, but I can't help wondering...

PREPARATION OF INKJET INK SAMPLES FOR METHOD TO MEASURE INK COLORS BY SPECTROSCOPIC ANALYSIS. See also: "Method to measure ink colors" by Grandad35 at: http://www.nifty-stuff.com/forum/viewtopic.php?id=2681 The...

If you want to have a CIS operate with a Canon printer that normally uses sponged cartridges, like the iP4200, iP4300, and similar, then get a CIS that produces a constant effective ink elevation and set that elevation correctly for your particular printer. It is preferable that the replacement...

Narmenia is having some problem with his printer and CIS. What I am reporting here concerns the particular commercial CIS which he is using. This CIS is quite interesting in that someone has figured out how to use a Marriottes Bottle in a system which will definitely provide a constant ink...

First, know that the Canon Pixma printers must have a negative ink pressure at the point of ink input to the print head. The print head operation depends on that negative pressure. The needed negative pressure is why the ink cartridges have sponge material just above the ink output port. The...

Someone said in a post or reply that this method had produced many refills without the cartridge blocking up or needing a purge. Can any members confirm this? I think I remember something like "20 refills with no problem". Anyone who has used this method a lot, please comment on your...

Since I don't own HP printers, I don't understand this exactly, but I think I get the general idea. "Hi & Bestech" is a company in Taiwan which has made various inkjet related electronic items. Amongst others, they worked out the first resetter for Canon CLI-8 chips. They also produce other...

My iP4200 isn't really that old, but it is no longer in production. That qualifys it for being called old by some. I find that this printer truly is the most clog free that I have owned. It has never failed a nozzle check test print. It has withstood a couple of 5 week idle periods and...

I am doing some research on the workings of the Pixma series printers, such as iP4200, iP4300, and others in the same category which use the CLI-8 cartridges. I want to dig into the print head and see exactly what is inside. I can't afford to wreck a new one. If someone has already torn one of...

Has anyone cut open a Pixma series print head? I would like to know what is inside. Most all on this forum know that there are print head input ports where the cartridge exit ports connect. On a new or clean print head it is easy to see that the input ports have an extremely fine screen...

A RESETTER MAY EXIST! I AM MOVING WITH CAUTION. THERE HAVE BEEN FAKES. I have been communicating for some time with a company in Taiwan. They specialize in making replacement chips for toner carts and inkjet carts. I was interested in them as they claimed to be making progress on a resetter...

WARNING: This may be an FNO Post. The Canon Sponged carts are really very special. They represent an invention that may be simple in its manufacture, but it embodies very shrewd engineering and probably is the best inkjet ink cartridge that has been made. Over the past few months I have...

:o I'll start this out with my startling report concerning last night's operation. It has become a FNO post. Sorry :( I have been refilling CLI-8 color carts in my Canon iP4200 for a while now. In their turn, each cart was declared as empty and I did the "continue printing" command with the...

Rob, I realize that the number of posts on the forum determine what title a person gets. In my case, I don't feel I deserve the title "Inkjet Guru" as yet, no matter how many posts I have posted. Perhaps you could have a "title reduction-by-request" rule. For instance, if I reached the...

Please tell us, with complete details, any clogging or other printing problems you have experienced during long-term usage of your CIS system. Be sure to list all the details. CIS Maker, Printer Model, Ink brand and type, the Problem, and about how much printing or time before it showed...

This may be a FNO message. In the search for more understanding of Canon's chipped CLI-8 cartridges, I wonder if anyone has considered just how the ink information is really managed. Knowing the whole story could be very interesting. It has been suggested that the count of ink jet commands is...
