Review on 🖨️ High-Quality Smart Ink Replacement Cartridge for Canon PGI-280XXL CLI-281XXL PGI 280 CLI 281 - Compatible with Pixma ​TS9120 TS8320 TS8220 TS8120 (PGBK & BK/C/M/Y/PB) 6 Combo Pack by Andrew Gomez

Large and small black cartridges replaced with Smart Ink compatible cartridges. About the next twenty printed pages were just blank pages of text, there were one or more fuzzy lines, and sometimes it was even impossible to see what was printed. The few color pages that were printed caused no problems. I replaced those two black cartridges with Canon cartridges and the problem was gone. I plan to try them again, maybe they were just a little dirty and everything will be fine. Suppose I find out more later.
