Now I can also see the problems with the cyan nozzles. It looks like a worn printhead to me. But it is very difficult for me to see. I think it is the limits of what your scanner, my monitor and also my eyesight can resolve. I also think the paper structure is of importance. High resolution paper or photo paper might show the defects more clearly.

Here is cyan nozzle check from an MP980 scanned at 1200 dpi on an Epson V33 CCD scanner, click to enlarge. Notice vertical division.

And here is photo black from the same printer in 600 dpi. Notice defects and the larger droplet size, click to enlarge.

A nozzle check on photo paper might show possible defects more clearly in a high magnification/resolution.

I reckon everyone is taking these prints completely out of context, they look fine as they are, come on guys, what do you expect when running with 3rd party inks, you might have a point if we all were using OEM inks, and I’m certainly not, and my printer works fine..:eek:

On photo paper it seems the Lucia inks are not very well suited for the Maxify :(.

When you print on plain paper, using standard quality settings, have you noticed ink starving on images containing large areas of cyan(ish) color ?

There is some banding in standard quality (as shown beneath) , high quality is flawless

FYI I had error B504 today.
This is triggered by the ink sensor in the bottom of the printhead as @Artur5 showed in detail.
I didn't fill enough ink, so the carts were empty before the chips.
To the average user this is presented as unrecoverable, since it is impossible to change the carts with the normal procedure (although some googling learns how to unlock the printhead by turning the wheels at the left).
I removed all carts and the 3 colors where 47g, same as an empty OEM.
Refilled all, Y again with octopus.de.
Nozzle check OK after one additional cleaning.
Will follow up, maybe there is nothing wrong with the octopus.de ink.

Canon announced 2 Maxify printers with ink tanks, the GX6050 and GX7050
https://www.canon.co.uk/printers/maxify-gx6050/

The printhead is the same, and the maintenance cartridge is user replaceable.
Refill ink bottles GI-56 BK,C,M and Y cost about €30 for BK and €25 for colours (less online).

Volume information has been removed on most sites but I have seen 135ml.
Since for C,M,Y Canon claims 14.000 pages, almost 10x a 2500XL of 19ml, the gain is substantial.

Since I continue to have problems with the cyan, I ordered a GI-56 C to refill my MB5150, but the item cannot be delivered at this moment.

PS: volumes have been confirmed as 135ml for colour and 170 for BK

I received the cyan bottle.

According to the first line Canon does not give the illusion it can be used to refill existing Maxify cartridges :(.

We have to take @PeterBJ 's suggestion about tricks into account.
I was thinking about rinsing a cart several times, first with water and afterwards with isopropanol to avoid yello gello situations.
I could eventually use transparent Chinese refillables.
I will use an old printer with a not optimal but useable printhead to test.

Any suggestions welcome.

Yes, just refill and print. No fancy maneuvers.

I read the first line and also thought about Yello Gello. And plain old color shifts as well. Our paranoia as refillers familiar with Yello Gello is showing.

Maybe mikling will tell you his secret Yello Gello testing method and you can experiment before refilling your cartridge.

Isn't Yello Gello correctable?

If, and it is a very big "if", the ink causes a type of "Yello Gello" then you can clean and flush just like with the old Yello Gello issue.

BTW, if Canon is so nefarious then why don't the other inks form a Gello as well? Yes, there have been isolated reports of one other color having alleged issues, but why not MORE or ALL colors affected?

More likely explanation is that Yello Gello is an unintended byproduct of a formulation change without intent to screw refillers.
