Review on 🖨️ JetSir Compatible Ink Cartridges Replacement for Canon 270 271 XL 6 Color High Yield (PGBK/Black/Cyan/Magenta/Yellow/Gray) - Compatible with Canon Pixma MG7720 TS9020 TS8020 Printer by Matt Morgan

Two out of three black JetSir cartridges are defective. I bought four but haven't tried them yet. Print result is illegible. Edited: The printer was set up in two different ways: (1) Printing in color. (2) Black and white printing only. New JetSir ink cartridges installed in a two month old (new!) Canon TS9020 printer. Illegible results were the same for both black ink cartridges. Only the first of four black JetSir ink cartridges printed clearly. A fourth JetSir black ink cartridge was also tested and this cartridge was also unreadable. inkwell. You were right to leave a review for Revain. JetSir contacted me and offered to send a replacement or refund. I have accepted the return. From now on only original ink tanks for my Canon printer.
