This is a new compatible paper feed roll for Canon printer MG series.

For other models, some can be easily replaced → Please search online. I am selling this hoping to be helpful to those who can disassemble/replace/assemble it themselves. Since the paper feed roll is made of rubber, paper feeding becomes unstable due to aging deterioration, regardless of the cumulative number of printed sheets. I have purchased a large quantity for recycling, so it is offered at a low price. I have been using both the flat type and this radial type for about 2 years. ＜My personal opinion on the performance of this compatible roll＞ The paper feeding performance is equal to or higher than the genuine product. The conveying power of the radial type is almost the same as the flat type, and the grip is slightly better. There is no specific direction to install this roll. ＜Reference: How to identify paper feed problems due to roll deterioration or wear＞ Set a single sheet of paper in the paper feed tray, and while slightly pushing the back end of the paper in the feeding direction with your hand, instruct to copy or print. If you can copy or print without any problems, it is almost "paper feed failure due to roll deterioration or wear" → If you can feed the paper with manual assistance, it is almost "paper feed failure due to roll deterioration or wear". There are various other causes of paper feed problems, but about 90% of the ones I have recycled have "paper feed failure due to roll deterioration or wear". If you hear a "crack" sound like plastic breaking or a scratching sound during the initial operation when the power is turned on, it is a paper feed failure due to mechanical damage. In this case, it will not be fixed by replacing the roll. ※ Various parts must be removed and installed to replace the roll. ※ Support via text messages for disassembly, replacement, and assembly is difficult, and I basically do not provide support. I intend to answer questions to the extent possible... To keep the price down, it will be shipped by regular mail.
