@rodbam: This type of failure does not seem like an electrical problem in the printhead, it appears to be a nozzle issue. Electrical failure produces a more erratic pattern, if you even get a print.
And "fixing" the printhead, I wouldn't even begin to think that. On Youtube search...
A pitch for Canon. There is a feature that is spoken of very little. It's the Preview.
This is not a preview that your desktop software generates. It's a preview that the "Canon print driver" generates.
With this I am "really" satisfied that the printer will get what "I thought I sent"...
I suspect the print head issue comes up when users try to get the last little bit of ink out of carts, and a channel runs dry. That's fatal. No chance to recover from that. If you are diligent and check the ink periodically, and especially when you print a lot, then I am inclined to say that...
Remember that the window cleaner should have "no additives", only Ammonia. The "D" version should be OK, it's deodorized. I can't vouch if there is anything "added" to the "D" version, but I have had no trouble. Sometimes it takes a couple of stores to find the plain version. Sometimes is is...
Rule #1 of Troubleshooting: Do "one" thing at a time, so know what works. Otherwise you might get a fix, but you won't know which step did the trick, and you will find yourself doing the individual steps somewhere in the future anyway. So spend the time the first time. Good luck.
Apologies for off topic, but @stratman I just love your avatar. I have a pair of scissors from my youth, from an incident with a cord. Thanks for the chuckle.
In the 80s and 90s I used to write print driver (modules they were called then) to access special print features, because back then even the lowly person (independent programmer) could get PLC language manuals, and from the printer manufactures "ALL" the setting available and accessible on "ANY"...
@Artur5, what I described above was only to set up the Wifi configuration in the printer with the Canon install program, but with a USB cable from a computer (or laptop if you have one). After the set up the USB cable is disconnected and the printer can then be accessed via WiFi, and by any...
@Artur5, I have also felt like an idiot regarding the WiFi install method. Since then, I have wondered if it isn't perhaps a software problem with the WiFi install program. I had not been able to get the connection correct via WiFi install. And that had been in about 5 or 6 locations and from...
What hasn't been said is that Ammonia in gaseous state is an extreme explosion hazard. In the right air/ammonia mix an explosion can be started by a simply static spark. There is no safe way to handle ammonia when air is present.
Thanks @stratman, yours is a very good explanation. So if I have the luxury I let the carts dry the 4 weeks, but in a pinch, if I need a refill earlier, I can shorted the time. Thanks again.
@stratman, you raise a good question. You say "should" not be a factor in creating Yellow Jello. So I do need to ask, do you mean certainty as in "is not" a factor? That I could live with, and would like very much. "Should" is a little ify for me.
I do have to admit that I have no...
Thanks @The Hat, I mentioned that the 4 weeks are arbitrary. Only sort of. I got started with refilling when I simply refilled an OEM cart, without any research. The resulting yellow jello forced me to study the subject. I found that the instruction are good for everything except the drying...
The only thing I would add is a cation about the Jello Jello. Make sure the cart is dry before you refill. Period. The yellow ink is simply not compatible with the flush water, or any hint of it. I suggest, so don't have disappointing results, plan well ahead, so you have lots of drying...
