Review on GPC Image Compatible Ink Cartridges for Canon PGI-1200XL: Ultimate replacement pack for MAXIFY MB series printers (5-Pack, Black, Cyan, Magenta, Yellow) by Roberto Strumer

Before ordering from this supplier I have used ink cartridges from other manufacturers with no problems. But there are issues with the very low quality ink supplied by this supplier. Details. Ordered twice from this seller. I put one in the car and set the other aside as a reserve. And the first set seemed to work fine. at the beginning. When the first set ran out, the cyan (C) color suddenly stopped printing completely despite the presence of ink. Cleaning and deep cleaning failed several times and the black cartridge also started to clog the corresponding nozzle. After pulling out the second set of cartridges I replaced the cyan and black cartridges but to no avail as both were badly clogged and a thorough cleaning didn't help. Cartridges and cleaned in hot water. After cleaning, I reinstalled the jet nozzle assembly and ink cartridges and started the deep cleaning. The blue color worked now, but the black remained clogged, and continued use of black only made the situation worse. Now there were large white streaks that should have been black. One observation: when cleaning the separate jet nozzle assembly, I noticed large black particles (of black ink) in the water. It was bad. Well made ink should not have large visible particles in the ink. And it quickly became clear that it is these particles that clog the nozzles of inkjet printers. I do not recommend using these cartridges. And now I need to replace either the printer or the jet nozzle assembly.
