Stripes in Print Test, Deep Cleaning and Head alignment doesn't help

[stratman]

That said, I wonder if we have discovered a "PM ink gelling" issue, similar to the yellow? Is Canon adding something to the CL42 carts to foil our refilling efforts?

If this were so then why isn't the 'additive' in all of the colors? It is far more likely that Yellow required something different for the performance Canon wanted.

In the USA, manufacturers cannot subvert the consumer use of non-OEM replacement parts when it comes to warranty. For instance, you may use any brand oil filter and oil in your car. As long as these meets spec then your engine is still covered under warranty. Manufacturers would pay a heavy price in court for adding a substance to purposefully cause non-OEM oil to malfunction. Same would hold for Canon purposefully causing gelling and destroying the print head and/or purge unit. Of course proving malicious intent is another thing.

PS - Lee Harvey really did it by himself.

Perhaps the additive is being rotated through the colors...

If Canon can (and does) refuse to stand behind a warranty because non-OEM "compatible" carts were used, then what's the distinction between that and a non-OEM oil filter?

Dunno, but if you have lots of money and obtain scientific evidence that the non-OEM ink, cartridge and chip pose zero risk for malfunction, THEN you have a case to litigate. By the time the dust settles, Canon will no longer have the parts or printer left to sell you. But, you will have the satisfaction of taking on an evil corporation and, like Charlie Sheen says, "winning"!

Just a quick update—I've had my printhead soaking for the last 24 hours, and am going to leave it to soak until I get home this evening. Once home, I will let it dry out and then try another. In the meantime, I also completely flushed out my PM cartridge.

@turbguy, thanks for the advice on the warranty.

@martin0reg, thanks for your suggestions. If I'm still having problems after tonight, I will try them. I don't particularly want to use up my Canon ink for diagnosing this issue though, so I probably won't try that. (Note: I did use the Canon ink for several prints when I first got the printer). Could you explain a little more what you mean about internal cleaning? What kind of cleaning solution would I use for that, and how would I go about it?

@martin0reg, ..Could you explain a little more what you mean about internal cleaning? What kind of cleaning solution would I use for that, and how would I go about it?

Before external cleaning (what you are doing now) you have tried normal and deep cleaning in the printer menu, which is internal cleaning with ink. Instead of ink you can use cleaning cartridges (don't know if there are cli-42 available) or you can make your own. For this purpose you can use one of the many ready-made cleaning fluids or you can search for pharmacist's solution here in the forum. Ammonia is said to be efective on bubble-jet printers. Internal you may clean the whole ink path from cartridge to the ink pads of the printer.

With external cleaning you can handle the process more individual .. warm water or cleaning solution on the inlets, soaking from underneath with wet paper towels, blowing -carefully- compressed air in the inlets and other special tricks..
..honestly my success rate here is under 50% because often there are nozzles already burnt. Canon print heads should not be considered as permanent as "cold" piezo print heads from epson..

I dont really understand why there is so much fuzz about the stripes on a BubbleJet Printhead.
If these nozzle dont unclog within a few cycles and maybe manually by steeping it into a shallow plate with a little bit of destilled water the nozzle a cleary burned out or there is a eletronical malfunction
Canon does NOT use piezo based printhead its thermalbased by heating up the ink and bursting it out this will lead into steady deterioration

If a epson printhead is clogged? give it the BEST ammonia based fluid with firm pressure and let it soak for at least 4 hours, inkjet waterfall again an voila done

Canon Printheads are ALL "customer friendly" to insert and eject
ALL printhead are even aviable at stores for popluar printers.

I once had it with the "good old canons" without the Chips and stuff but now adays I switched from BubbleJet > Piezo Printhead
Epson owns the patent on the technology and they have some license agreement with Brother and Ricoh, since booth of themn adapted the Core technology and use it on their on product line, but Its not really comparable to the Epson printheads

Just tested the printer again after 36 hours of soaking the printhead in cleaner, and flushing the PM cartridge. Sadly, there was no improvement. I think at this point I'm going to look into getting my printhead replaced under warranty. Thanks for all the help, guys!

Please find me a qy6-0049 (ip4000) for a reasonable price...apparently it is out of production, latest price was ca. 70euro, good as new it costs 150euro on amzon, refurbished from ebay means risk of bad nozzles..
A new prinhead for pro-100 (8 channels) is expensive too, because of 8 color channels.
So a little fuss with cleaning COULD save a lot of money...
