Hello,
Yesterday I did a PK->MK ink swap on my 7900 printer. My MK cartridge was showing 1% so the printer told me to insert a new MK cartridge to perform the swapping.
I did that, and put back the old cartridge back in the printer afterwards in order to use every last drop of it for printing.
So now I have an almost empty cartridge in my printer, and an almost full one on my hands. What should I do about it to store it safely so that it doesn't dry or something ?
Are there any recommandations you could share about this ? Is there some kind of risk that my cartridge might be unusable because I have not kept it in mint condition ?
Thank you !
