Ip3000 PGB spotty again

[The Hat]

is it the internal structure of the cart itself, or is it both?

I don’t really know the answer to that question, but the reason I switched was to have only one type of cartridge for several printers, lees chance of problems and mistakes, same with the inks.

The older Canon printers were much more accommodating, forgiving and easier to work with..

Much less locked down, too. These days, Canon (like most printer manufacturers) seem to view their customers somewhat as adversaries. :-(

I foresee a future where the new generation of printers will explode or electrocute the user who tries to install a non-original cartridge. Third party ink suppliers will sell also insulating gloves, protective glasses and bullet-proof jackets.

Mikling is testing a line of products and JToolman is making videos. The Hat doesn't give a crap and does as he always does and it works.

Oh, absolutely, the printer makers see most printer users as suckers.

But not us, I suspect. We're more adversaries, because we're actively subverting their business model by doing our best to pay them less (or nothing) for their ink.

That said, I'm sure they see commercial refillers as fire-breathing demon-spawn.

Obviously they're combatting refillers. Otherwise why would Canon have spent R&D money on chipping, opaque-ing, redesigning and shrinking their ink carts? If they weren't worried about refillers, they'd still be using nice big transparent unchipped carts, don't you think?

IMO, the printer makers chose the wrong business model. IIRC, the very early inkjet printers had big tanks that you had to refill, and there's been a little movement back to that in the last few years. I don't get the impression that "eco-tank" and its cousins have caught on that well, though. Who knows, maybe printer buyers would actually prefer to pay $40 for the printer and $4000 for the ink over its lifetime, cart by cart, instead of slapping down $400 up front for a printer with a near-lifetime ink supply.

In any case, I'm keeping my IP3000 as long as I possibly can. :-\

To that end, I did an hour-long printhead soak in ammoniated Pharmacist's solution last night, following PeterBJ's instructions. The printhead is now drying in front of a fan. (The weather's been too warm here to use a heat lamp.) I'll leave it there until tonight, close to 24 hours of drying time, before reinstalling it.

If that helps, but doesn't entirely fix the problem, I'll try a 24 hour soak.

Fingers crossed that I didn't do something wrong to wreck the printhead or printer.

Well, this has been an adventure.

When I put the cleaned and blow-dried printhead back in, it had no pgb at all. Colors were barely there.

After 2 purge cycles, I had streaky color, but no black.

At 5 purges I put about 8-10 drops of Windex on the outlet of the PGB cart, which I think may have helped. On the 6th purge, I started to see hints of PGB.



By purge #10, I had all but 4 pgb black segments back.



I'm now up to purge #14, with no further improvement. In fact, now I have FIVE missing black segments.



What worries even more is the tiny gap in the light magenta. That wasn't there before I did the manual head cleaning.

Here it is in the service test print.



So far, repeated purges aren't shifting either the pgb or the magenta clogs -- if that's what they are.

I'm at a loss, and now hesitant to use the printer at all, concerned about causing further printhead damage by printing with clogged nozzles.

Any suggestions? Yet another out-of-printer manual cleaning, this time letting it soak a full 24 hours?

If I'm careful to keep the liquid it's sitting in no deeper than 1-2mm, do I dare put the printhead back in the printer without too much drying time? I think that long dry-out may have contributed to the need for so many purges before I started getting output.

Am I likely to lose more than I gain with another manual cleaning?

PS (edit): The magenta seems to have come back.

However, black got worse again. Running a purge got me back to 5 missing segments.

Pharmacist writes here https://www.printerknowledge.com/threads/cleaning-solution-the-ultimate-test.5296/ of using his solution in cleaning carts, but he's talking about Epson printers. Do you think it would it be safe to use that solution in a BCI3e-BK cart? Or maybe straight Windex? Purging only? Printing or purging?

@kanonvater, From what I can see, your going to kill your print head with all this purging and external cleaning, just leave the Feckin thing along and get on with your printing, the head will settle down once you do that.

Putting a dry head back into your printer will always give you a poor nozzle check at first, you should have put a couple of drops of water onto the ink inlets before inserting the carts or if you prefer pharmacist’s solution, both will work..

Thank you.

Maybe I'm too cautious. I'm a relative Canon newbie. Until early 2017, I'd owned only HP and Epson inkjets. The HP seldom clogged. The Epson was partly clogged most of the time, but printing in that state didn't damage its piezo printhead.

My first Canon in 2017 was a nice low-page-count IP5000 that had been sitting on a shelf in the previous owner's office for years. Out of ignorance, I didn't recognize ink starvation, and had no clue what the yellow light and pauses during printing meant. So I killed the printhead, and QY6-0057 printheads are scarce and expensive. :-(

That's why I'm careful with the 3000. And it does seem to have residual clogs in PGB. The "floating clogs" seem to be pretty well gone now, but so far 5 segments are consistently absent in nozzle checks and service test prints.

Are you saying it's OK to print with the head in this state?

Sorry about that. I wasn't deleting the names. I just didn't know how to include them. Now I do.
