This genuine Canon 3785B002AA toner cartridge has been manufactured by the same folk who produced the Canon IR-C2225i and all other compatible printers. As such you can expect flawless comparability and performance from the moment the Canon 3785B002AA is installed. The yellow toner powder contained within the 3785B002AA has been formulated to fuse at the same temperature produced by your printer, to minimise waste and ensure that it is firmly fixed to the paper. Prints when using a Canon CEXV34 yellow toner cartridge are unmatched in quality and more than justify the cost of purchase.
