Yes, but such a large label sounds fiddly to apply on a consistent basis. Not to mention significant added expense if you do it any more than occasionally.

I get what you mean, but easier said than done goes without saying. A used DL6 is relatively cheap but a pain to ship and takes up a ton of space. Space I don't have, 14 printers later...

It seems pretty instant in my experience. The biggest single factor in air uptake has always been disuse for all three of my tanks. Right out of the box up till after 1000 pages and onward

Perhaps. I would just like to minimize the amount of extra workflow needed to accomplish a good backprint, especially minimizing additional materials required.

My only concern is it might smear more while in shipment or be affected by temperature/other variables. While it may work, it doesn't seem like a bulletproof solution and it leaves more to be desired for long-term/archival purposes. Just thought, I'll have to try laser backprint before...

I don't have to do much for power cleaning. Once every few weeks maybe. Which is low enough to write off as regular cleaning imo. Daily maintenance prints stop me needing to do any cleaning most of the time, including the automatic idle timer cleanings. But I get what you mean.

I've also had this idea. Unfortunately (only in this context) Canon paper uses this lining and that prevents inkjet adhesion. Something I will say is that at work, we have a Fuji (Epson) drylab which prints backprint info (order number and whatnot) onto the lined backs of roll paper using a...

Had this issue on a P6000 at work and this turned out to be the issue. Years of use, daily cleaning cycles, and a wiper that's probably the original... led to a lot of crud on the print head. I widened the platen gap to band-aid the issue and discovered shortly after when I stumbled into an...

Also, your printer will composite color ink into the black in order to correct dull and biased color on the paper. Black ink tends to look duller, "greyish," more than true deep black. And, the ink tends to be biased, at least on color printers. Pigment black has a green bias and dye black has a...

In theory that print head shouldn't be at risk of dying, because anytime air does get in the line, I do a heavy cleaning cycle until it's out. And I never wind up with air in the lines if I keep doing that maintenance print regularly. Same behavior across the board, all the way up to my pro...

I agree air ingress is bad, don't get me wrong. I'm just saying that for me personally, my maintenance routine solves it enough where head replacements aren't worth the expense (and I don't think it would ultimately fix it). You could be right on that gasket comment. My guess is either that or...

I'm skeptical that it's some kind of damage that's causing this issue. All three of my Canon tanks have done it. Different models, different heads, different ink processes, etc. And they all do it. I'm inclined to believe it's a design flaw. Canon's bad about stocking replacement heads in their...

A dead nozzle, at least in my experience, is when a thermal print head nozzle has been electrically destroyed (usually by overheating, or running it dry which is just extreme overheating speedrun). I suppose yeah it would probably still pass ink during a cleaning cycle since the purge plate is...

No change -- Only a couple days later and my black line was full of air again on my G7020.

Interesting you suggest diluting them. What ratios?

If you get one from eBay or a similar source, make sure to get one that's still sealed in its plastic packaging. There's a storage fluid inside the print head to prime it for charging, which you don't want dried out or clogged. If the print head is opened, it's probably been used in another...

Second on this. As great as Epson ink can be, it's essentially designed without heat in mind since PrecisionCore print heads are cold-firing and don't need robust cooling. Canon and any other OEM that doesn't license Epson's PrecisionCore (cold-firing piezo nozzle) tech* uses thermal print heads...

Now that you mention it, that rang a bell... I remember seeing labels on the print heads for all of my tank printers and being under the impression that they were permanent-type ones not meant to be removed. I just peeled them off both my G620 and G7020 printheads, reinstalled and did a...

160 and 330 ml carts are just an empty case with a tube in them. No sponges to be found. You can see inside one here: I have not seen inside the 700 ml carts but I assume it's the same deal.

Canon ought to overhaul their design to be CISS to begin with. I suspect it's the overall theme of "retrofitted CISS" that's the cause of the issues. Canon having also done essentially an OEM retrofit falls in line with that. I agree that refilling is, in a way, more reliable/less fiddly...
