Questions about Canon MC-G01 Maintenance cartridge

The part in picture 2 is certainly not the maintenance cartridge, but a toner!!!

Hello DIGITEC My Canon Maxify GX6050dn purchased on 04.04.2022 reports that the maintenance cartridge Canon MC-G01 is almost full and I should order a new cartridge. That's exactly what I wanted to do now, but this item is not available at all! The printer printed about 5'160 pages with the old cartridge. I can print maybe another 2-300 pages and then it's over. But the printer's warranty runs until 04.04.2024. Because I'm afraid that the print heads will dry out if you don't print for a long time, can become a warranty case. I need this "Canon MC-G01 Maintenance cardridge" as soon as possible! When will the cartridge be available? Would buy 2 or more as a reserve so I can print (5'000 to approx. 7'000 pages/year). Please let me know: When will the Canon MC-G01 Maintenance cardridge be available? Or where can I find such an item? Thanks for the information! Kind regards M. Bracher

Good day How do I dispose of this cassette correctly? It says: Do not throw in the rubbish. It says: Hand in at the shop. How do I dispose of this cassette correctly?
