I print my own art prints using my printer on the Instant Ink service. It got to a point where my colour cartridge was 'low' but not enough to replace, but I was wasting tons of pages of my monthly allowance working out why my prints were not printing enough blue. No re-alignment, cleaning, adjusting colour management, or manually checking the cartridge fixed the issue at all - it just stopped printing with enough blue. Eventually a new cartridge arrived and I replaced it. Blue was fixed!
This time, I printed quite a few yellow-heavy prints and now this cartridge is low, but specifically low on yellow. I once again wasted even more pages trying to troubleshoot the issue. I think I have wasted around 30 of my pages trying to troubleshoot the issue, and I have only had 100 since the start of my subscription. This has been very frustrating- I feel like the only solution is to replace the whole cartridge whenever a colour runs dry. However, I also received an email from the Instant Ink Service pointing out that I shouldn't replace my ink cartridges until I am told to do so, and I think it implied that there would be a cost if I did. I don't know what to do as I saved up for this printer specifically to do this job. The bigger solution would be to get a printer that uses separate colour cartridges but I couldn't afford any of those, so what next? Will I really be charged for changing my cartridges early? Is there something else I can do to make my printer as efficient as possible?
