Canon's QY6-8018-000 printhead is compatible with several models in the Canon PIXMA G series, including the G1400, G2400, G3400, and other similar models. However, there is no explicit information confirming its direct compatibility with the Canon PIXMA G7050. For the PIXMA G7050, Canon usually offers specific printheads such as the BH-20 model, which is listed for several MegaTank G-series printers, but the G7050 is not explicitly listed in the available sources.

It is therefore likely that the QY6-8018-000 printhead is not compatible with the PIXMA G7050. For certain compatibility, it is recommended to use the print head specifically designed for the G7050, or to check directly with Canon support or in the printer manual.
