Keep in mind that ip4500 is a printer made much earlier than Pro9000 with 2 picoliter nozzles. If Canon indeed has a much improved design for 1 picoliter nozzles why the Pro9000 did not use the technology? In my opinion 1 picoliter nozzles are more pron to clogging for a simple reason. An 1...

Let me try it again with the word "please". Mikling could you please explain why the grey ink is a crucial element fro printing color photos? I want my yellows and reds more saturated. How would the grey ink help me to achieve that? I know the grey ink helps my greys in my color photos. But I...

The OIG thing by Koichiro Kawaguchi from Canon may be a good study/research but have you wondered why MP980/990 got poor reviews by professionals and end users? I am one with a challenge attitude too especially toward something like OIG that is suspicious to be a marketing hype. If you believe...

What I desire from a good photo printer is having totally saturated bright red and stunning rich yellow that are never achievable from inkjet printers with dye based ink. By adding a grey and several levels of grey/black ink it will not or never make the red and yellow more saturated. There is...

Great. Canon does make good printers. What I should have said is a 1 picoliter print head is more pron to clogging than 2 picoliter or larger ones. It will certainly be more reliable for a wide format printer to be on a safer design with a 2 picoliter printer head that PRo9000 uses. The nozzle...

Interesting. How did you determine it was the deep cleaning that burnt the print head and not the printing after the deep cleaning? Well, the nozzle check is not likely to burn the print head so I guess the deep cleaning did burn it.

Great post, Stratman. I can tell that you spent a lot of effort in putting it up. It is the best answer to this type of problems. I had a same problem before when I refilled and installed a BCI-3ebk into my mp780. It printed blank on the nozzle check initially. I had to do two cleaning cycles...

I wonder how many have followed your suggestion and made a false diagnosis of their purge units as a result. Nevertheless it is never too late to make a correction. A much precise way to test the purge unit is to fill up a set of cartridges with isopropryl alcohol or simply water. Plug in the...

Same here. I tried the German method on only a few cartridges. It can only be considered a hack. Never worked well for me. All you need is to find good silicone plugs and drill the top of the cartridges.

Probably not until Canon reaches some volume of sales of these printers. 3rd party ink manufacturers will not produce the new ink until there is a volume demand. Now the problem is if there are no refill inks and no resetters available who will buy these printers?

The reason k3 ink has multi level of bk or grey is because the ink is pigment based that has a narrow gamut. Unlike like dye black ink, small droplets of black pigment ink can not produce light grey satisfactorily on paper. The dye black ink with the help of 1 pico liter droplets can produce...

I just refilled an IP4000 this morning. It uses unchipped BCI cartridges. I refilled the BCI-3ebk. After I resinstalled the cartridges I waited for a couple of minutes then ran a nozzle check. It printed all colors fine still but the black grid on the top was completely blank including the...

You are absolutely right. Lack of cyan will make the print reddish. Thanks for the correction. Lack of magenta will cause greenish tint. The important point is if the printer is lack of cyan (or magenta) it is telling that the cyan (or magenta) cartridge is not flowing well. This requires...

If you have a Canon printer with chipped cartridges you can observe the behavior of cleaning cycles. Just refill your cartridges without resetting. You will see ink level monitor disabled. Print something a few times. You can see if starting up a print job will cause the printer to run a...

I don't use HP printers so I don't know if they will run cleaning cycles if you remove a cartridge and reinstall it back. If doing so allows air to get into the print head a cleaning cycle will be needed to get the air out before printing. For Canon printers removing ink cartridges will cause...

Just do what lashdudette did by refilling your PGI-5 with a photo black ink. It is a tip posted on this forum before and it worked for me. After refilling with photo black ink just use it to print some text. Not a whole page but a few lines to begin with. Print larger font. Somehow by printing...

Had been flagged? Why? I thought the Hat needed some entertainment. He made an inappropriate generalization of Canon printers. The Pro 1 according to his description is apparently very different from all other Canon printers I have used in terms of how much ink is wasted by the cleaning cycles...

Hat, I have been one who debated in threads related to the subject before. You missed an important point in his words. This is Dave's words according to turbguy: "I have never heard of any complaints from anyone about clogged purge unit." Now let's look at your words: "what I said was for...

This is just your own opinion. If your photos are all with low contrast, low dynamic range of light, low quality snap shots you naturally will not need the extra photo black. You won't need Pro9000, nor Pro 1. All the extra inks and colors would be a waste of money. If you print images with a...

Hum... I think this is wrong too. Waste more ink? Do you mean more than 5 ml? I guess not. Waste more ink when using non-OEM ink? Sorry, I am in a bad mood. I am picking words from the HAT and your posts. Seriously, there is no more waste of ink regardless the ink is OEM or non OEM. If a...
