Pro 10s magenta

[palombian]

Correlation does not imply causation. More information not yet revealed required. None know the batch identification or the particulars of each refilling behavior or condition of the cartridges.

Again, how does the overspray/whatever of Magenta in Palombian's nozzle check relate to the ink starvation appearance he also suffers from? These seem to be distinct issues.

....

This magenta issue remembers me of comparable observations with the 9500 magenta (IS formula 6162).
I replaced this with Prodinks magenta (with the MBK the only ones who had no clogging ) and afterwards with the PC new 9500 formula magenta.
It was mostly a banding pattern, do not remember nozzle pattern issues.
But it was cartridge related, I sorted them out bad or good.

Will rinse a PGI-72M cart and refill again with Octoinkjet magenta. You never know.
As already suggested alternating with OEM could keep the nozzles clean.

Since @mikling warned about using PRO-9500 inks in the PRO-10, I will not go this way at the moment.

PS: I try not to read too much in nozzle checks.

This Magenta ink issue may or may not be Canons doing, they could have changed something that makes using 3rd party magenta a particular problem in the Pro 10’s, similar to the yellow in the Pro 100.

Ink suppliers get there bulk inks in batches, they don’t mix the raw materials themselves, so if there is an issue out there with 1 end user then it stands to reason all will have the same problem, as this is not the case then we shouldn’t over react and panic.

Using any 3rd party inks in your printer (Especially Canon) is a gamble and should be used cautiously when switching to new batches of ink from whatever source, issues can sometimes arise when an ink supplier mixes two different inks together to get a better formulation and calls it their own brand..

As I have said on many occasions 99% of the time it is the end used that makes the mistakes and are not aware of it, resulting in output issues, I refill my own carts and am as much to blame for all my own poor results, and its painful to undo something to get back to normal printing.

P.S. my OctoInkjet Magenta batch number is PGl- 6162…

Just to note we're exploring what's happening...

I'm leaning towards a batch issue but can folk please contact me via PM or email with the batch references on the bottles so I can aggregate the information to determine whether it is a batch issue or something out of left field.

Should note this is not going to be the same with the Pro-9500 as the inks are different from the two magenta's we have for that printer.

Right... @Artur5 @palombian @Borut... One key additional bit of info' to check.

What is the state of the original Magenta cartridge you've had problems with... Critically...

1. Has it been marked as empty?
2. Did you drain the cartridge of any remaining OEM ink before use?
3. Did the cartridge sponge dry out or was it kept in a "wet" condition?
4. Is the cartridge your own or have you purchased/obtained it as an "empty" with unknown history?

Reason for asking is that I have some info back and two of the three had cartridges that were effectively empty and may have had some drying action. We've noted that cartridges that dry out really suffer from a heavily stained outlet sponge that is near impossible to clean out properly (Still working some suggested approaches on that point).

In terms of ink batches I need to double check the references against our stock log to see if the inks are all from the same batch or not. Interestingly enough it seems that purging the cartridges appears to clear the issue and installing an OEM cartridge immediately restores the nozzle function so it's not presenting as a clog within the printhead and/or nozzles.

Given the remedial action that seems to resolve things, the work-around (fix if you will) is to flush out the OEM cart using a little of the refill ink and then refill properly, using the flush clip to push/pull ink through the sponge... Use of a re-manufactured cart may well achieve the same thing but further testing needed.

Of course, timing wise, this could come at a better time... what with Christmas and all, but thanks for the feedback so far... I'll report back when I get new info'.

...

Oh and couple of pointers to avoid confusion/false-positives.

• PGI-9 Octoink inks are not same as our PGI-72 inks for magenta's or red
• PGI-9 Octoink inks have two versions... the older Image Specialists inks and our newer set. Each are distinct formulations
• PGI-72 M,Y and PBK carts all gunk up when left open to air and are difficult to clean
• PGI-9 all carts clean up easy even when left open to air

Maybe the answer is to switch to a PGl-9 cart to rectify or relievate the ongoing magenta concerns that have arisen..

Thanks for the detailed information Martin. I'll try to answer your questions.

- Has it been marked as empty? -
I couldn’t say as I replace all the carts where one of them reaches empty. According to the probabilities, it’s very likely that it was one of the other colors. Even if the cart is declared empty, there’s always some ink inside. An empty PGI-72 weights around 18gr, and none of them has been less than 20g when refilling.

- Did you drain the cartridge of any remaining OEM ink before use?
Yes. As I intended to make a custom profile for Octoinkjet inks, I tried to clean well any residue of OEM before refilling with your ink.

- Did the cartridge sponge dry out or was it kept in a "wet" condition?.
I don't think it could have been dry. After replacing a cart (empty or partially full) I reset, refill again and put the orange clip. Sometimes I don’t refill immediatey but after a few hours, always keeping the orange clip installed. Anyway, except the first refill from OEM ink to Octoinkjet, the carts were never really empty.

- Is the cartridge your own or have you purchased/obtained it as an "empty" with unknown history?
I own two set of carts. One is the OEM that came with the printer and the other set are empty OEMs purchased from you.

As additional information, the smear/banding issues in the nozzle check didn’t start in the first refill with Octoinkjet but after the carts have been refilled two or three times.

Has to be seen.
When reading between the lines both @mikling and @websnail warn PGI-72 carts are not the same as PGI-9.
Canon had to do something to make refilling more difficult .

To haw no problems is must to flush the magenta cart out whit cleaning solution 10 times in and out.Then 2 ml magenta ink to refresh and then dump that ink and fresh refil.This is the best way.

Thanks for the info' @Artur5 ...
@Borut, @palombian... If you have any record on your carts with regards to the above that would still be appreciated.

I think the first port of call is going to be to send out a re-manufactured cart for each of you to test out... I have some PGI-72M's that are undergoing a new pre-cleaning process that I devised recently so I'll get those cleaned, dried and then refilled in the early New Year and sent out to you to play with... Long term I'll be interested to see if the issue is more refill count or time sensitive...

..

One key thing that I've noted recently is that I'm becoming less and less comfortable with the state of used carts for PGI-72's. Unless they are thoroughly flushed out the gunk sub-set are likely to be more problematic than good refill candidates. But that's a side issue for another day...
