My Pro-100, about two years old and running on MAC desktop, has suddendly begun printing magenta skies. This is a new problem within the past couple of days; other colors appears normal. I have been using
LD inks without issue for some time - at least three years. I have reinstalled the driver, set everything I can find to PS control over printing (as opposed to printer control), printed test pages, etc., but the issue continues. I suspect I am simply missing a setting somewhere, but perhaps someone has encountered and resolved a similar issue. Any help or siuggestions would be appreciated.

A printer cartridge may be underperforming. You could try determining which cartridge(s) affect this color. Then switch them out one by one to isolate the bad cartridge. The printer manufacturer may have help here. Consult it, too.

Thanks for the advise. I did change a couple of cartridges that were clearly low on ink, but not all of them, which might be the next step.

I'm not familiar with your make /model printer but---My money would be on an ink problem,, Either an empty or faulty cartridge or a plugged nozzle. There are a bunch of you tubes about how to clear clogged nozzles and built in nozzle/ink supply diagnostics in most printer's firmware. If printers are not used frequently enough the inks can dry out in a nozzle. How long had the primer been idle before the problem arose? Most printers have a head/nozzle cleaning cycle that you can run. It may take 4 or 5 cycles to clean the head

Have had the printer for several years - Canon inks - no problems so far.

Yes, a clogged nozzle could be the problem here. I've taken my printer to an authorized repair shop to have nozzles cleared. So also call an authorized repair shop for advice.

I also think this is what’s occurring. And an ink cartridge “underperforming” is a good way to put it.

At times when I get weird color results and check the ink levels it’ll say the levels are fine. However, if I swap out one cartridge at a time I find the culprit and the colors go back to normal.

Thanks for all the responses. Since all point in the same direction, I suspect my problem has been identified, and the fix pretty well defined. So I will go for the multiple cleaning, plus changing out the suspect cartridges. The printer is used all the time, so inactivity isn't the problem, I'm reasonably sure. But all the the responses are considered, sensible, and presented in a most helpful manner. Thanks again to all the hoggers - a great group of people!

Thanks, Fredrick; I will do just that, one at a time. Hopefully the problem isn't two that are underperforming. (New concept in printer ink - underperforming...). Failing all else I will just get a new
printer head and replace the whole deal. Thanks again.

Note: If parts start to fail, then you may wish to consider replacing the printer. I went through that scenario after consultation with a repair shop. Printers have a useful life.

The VERY first thing you should do is call Canon Customer Service. They are excellent.

I have been using the P100 printer for about 3 1/2 years with no problems I’m using after market ink and I have taken out and clean the printers head unit ones. If you follow cleanings instructions it’s very easy but a little massy. I run a “deep cleaning process” every few hundred prints. I’m very happy with my printer. Try it you like it.

I would guess the problem revolves around your use of LD inks. You may have run into an issue with non-oem inks. Best of luck.
