One nugget to add to this as I've spent a few months working on this... If one or more of the printhead labels are left in place they can create a tiny air gap that allows air in between the ink outlet in the lid and the printhead receiver. That showed up here with a G6050 that had a very slow...
I've never done it on a Pro-xxx printers, only G series units but no, I don't think there are any other values you'd want to play with without knowing what you're doing.
Just as an aside, if you get a Printer Potty and take a metric ton of photos and/or video of the disassembly, fitting and...
@pharmacist as you can imagine I agree wholeheartedly.
It's beyond frustrating though that Canon continue to create an artificial end of life scenario with their consumables policy on printheads. Granted the waste ink pad limits automatically reduce the potential market for replacements but...
Hey folks... it's been a hot minute (read: months!) since my last confession/post and I could use the collective brain trusts help in seeing if there's a way to reset the waste counter via the control panel on these Canon megatank printers.
Now, I should note that I have successfully identified...
Going to ask the question... Has anyone actually pulled a Pro300 apart to work out how to change the pads or fit an external waste ink tank?
Alternatively has anyone done the same on a Pro200? Asking as I may have the opportunity to do just that but I'd rather follow in someone elses footsteps...
It it's stupid and it works (or is helpful), it ain't stupid..
That and we all do "embarrassing" here... Some are more "experienced" than others... :hu :fl
Some good news on this... It seems Amazon are archiving rather than completely wiping the site.
https://www.dpreview.com/news/0507902613/dpreview-closure-an-update
So, at least the site will still remain available for some time at least. Just not as an active concern.
The one thing I would recommend is watching a few youtube videos that show to remove the scanner lid and access the printhead carriage so you can remove the ink feed buffers (the bits that take over from cartridges) and then check how much ink is actually in them.
NB: Watch the videos through...
Aye... and what makes zero sense is why would a company that has literally gigatons of server capacity not just put the site out to seed as a static archive rather than delete the whole thing?! As one Youtuber put it recently, it's like burning the library of Alexandria. Pure myopic stupidity at...
Little surprised that nobody else has posted about this but, for anyone that has used DPReview in the past or relied on it as a reference for photo or printing issues, you might want to be aware of this.
DPReview is being shut down by Amazon (the parent company) without a great deal of fanfare...
I can't help but wince as I read through all of that Mike. You've learned far more than I knew about these models and shared that information willingly so thanks for that.
I can't offer much in the way of encouragement except to say that were I in the same situation I'd probably be looking...
Ah, apologies... PC in this context is my shorthand for "Precision Colors", not "personal computer". The REdSETTER unit will work with any USB power source but generally we recommend using the Pictbridge socket in the front of the printer (assuming yours has one)
I would inject a small amount of air into the dampers so they're roughly 50-70%full of ink and then, holding the damper so the outlet is facing down, draw a small amount of ink through the outlet to ensure there's no bubbles in the damper outlet itself. That should do the job fine.
Chip resetters are pretty stable for the 250/251 and while we sell one at OctoInkjet we offer them more for folk who've imported their North American printer with them so there's little point in purchasing from us given the shipping cost and time.
Assuming the PC chip resetters are the ones...
Probably not wise... Canon inks need to be able to thermally expand when heated by the nozzles heating element to form a bubble that both bursts (to jet the ink on to the page) and dissipates the heat in the element. Epson inks are not formulated to do that so you'd likely stress the elements...
Just to add that when it comes to fading on pigments, I remember a time when early compatible pigments for the Epson K1 and K2 ink sets were known to have fading issues, particularly with regards to uneven fade resistance when some colours would fade far quicker than others. It still took years...
Yeah, Canon haven't incorporated a one way valve into their design which is a bit annoying.
Was just about to suggest that last. I used that approach on a G4511 but as it doesn't have a maintenance/ship clamp I used some plastic forceps to crimp the tubes. Was able to remove the black printhead...
The thing with the air ingestion is that if air is getting in it's because there's an air leak somewhere between the printhead and the reservoir ink outlet. It's incredibly unlikely that the issue is being caused by an air leak at the reservoir end and Occam's razor being a thing my bet is that...
More of an observation than concrete advise but I noticed that the ink connection system between the lid/tube-feed and the printhead tops was potentially prone to problems caused by lint, dust and other detritus getting into the connection point and creating an air channel that reduces ink flow...
