Hello! This is going to be one of three problems.
It is either going to be that the print head needs to be reseated, cleaned, or replaced.
Have you performed a head cleaning at all?
All you need to do to is pull each cartridge out and put them back in. Reseating is just a fancy word LOL! You have already done 99% of the troubleshooting I would do.
Now, if reinstalling the cartridge doesn't work, you should be able to get a replacement cartridge if it is new. That may be your best bet.
There are a few things that we need to make absolutely sure has been checked:
Are the print head nozzles clogged? If the magenta print head is clogged, it just won't print.
Did you perform a head alignment?
Did you try a Feed Adjustment?
Is the chip unit going bad?
The following parts are the usual parts that go bad on your printer:
Ink supply tank
I would check those as well.
Let me know if you need any documentation or anything of that sort. Also let me know if you were able to resolve this issue.
Yes, the exact same one. I have the manual. It has instructions on how to troubleshoot as well. Here is the link.
As far as my personal knowledge of printers in general, I immediately thought it was the print head or cartridge, and I have been doing this for 15 years. I would say follow the manual, and if that doesn't resolve it, it may need some physical service done on the machine beyond what you and I can do together. I certainly hope this resolves it but this is about as far as we can go without actually getting our hands on it.
