Understand.
However, it all becomes a trade-off with respect to your time, effort, and money. I tend to push to far into DIY repairs/fixes/workarounds etc. to get something working again.
Unfortunately the world is going against us all with respect to such things. More products are now made to be cheaper to replace than repair. If repairable at all.
Your ROI (Return on Investment) goes down quite rapidly as you spend more time trying to fix the printer. If you happen to have access to another print head then a swap might be worth a try.
Yet, even if a swap works, something else goes wrong and you are back to looking at a new printer.....
Decide when to "write-off" the printer. Once you reach that point > New Printer.
