The print head with the manufacturer product ID QY6-8002-020 is compatible with the Canon Pixma G6050. This is the black print head, not the colour print head. This corresponds to the description as a print head for the Canon G6050 and is specified as a black print head.

The printhead with Canon part number QY6-8018-000 is not compatible with the Canon PIXMA G6050. This print head model is suitable for other Canon Pixma G series such as G1000, G1010, G1400, G2400, G3000, G3400, G3800 and the like, but not for the G6050. For the Canon G6050, you should look for a specific printhead for that model, which does not correspond to QY6-8018-000. I advise you to consult the official Canon support or the printer manual to identify the exact code of the printhead compatible with the G6050.

The Canon printhead with product number QY6-8018-000 is not specifically listed as compatible with the Pixma G7050. Sources indicate that it is compatible with several Canon PIXMA models, including the G1400, G2400, G3400, G4400 series, but the G7050 is not explicitly listed among these compatible models. For the Pixma G7050, Canon generally offers specific printheads, such as the BH-20, which is compatible with several models in the G7000 series, but the QY6-8018-000 is not included in this list. It is therefore likely that this printhead is not compatible with the Pixma G7050. For confirmation, we recommend that you consult the Pixma G7050 manual or contact Canon support directly.

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.
