Compatible Canon PGI9MBK Matte Black Ink Cartridge W/ Chip for the Pixma Pro9500
for Canon PIXMA Pro 9500 MKII
These replacement cartridges are compatible only if all the installed cartridges are of this type. A mixture of these replacements and the original Canon cartridges is not compatible. Nozzle check will not print correctly until all the cartridges are the same type . I assume that this is due to the difference in the design where the cartridge meets the print head. I can't say that this is true for all the printers that these cartridges work with , but I know for sure that this is true for the PIXMA Pro 9500 MkII.
