※ This is a new compatible paper feed roll. ＜My personal opinion on the performance of this compatible roll＞ The paper feed performance is equal to or higher than the genuine product. ※ Note: There is a correct orientation for installing the paper feed roll. I will enclose a memo with instructions. ※ Replacing the roll requires removing and installing various parts. I will also include a handwritten, rough disassembly/replacement procedure for the MG3630/3530. ＜How to identify paper feed problems caused by roll deterioration or wear＞ If the problem is "paper feed failure due to roll deterioration or wear," it can be fixed by replacing the roll. Place a single sheet of paper in the paper tray, and while gently pushing the back edge of the paper in the feeding direction, give the copy or print command. If it copies or prints without any problems, it's almost certainly "paper feed failure due to roll deterioration or wear." In other words, if you can assist the paper feed by hand, it's likely "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've recycled have "paper feed failure due to roll deterioration or wear." If you hear a "crack" or "scratching" sound like plastic breaking during the initial power-on operation, it's a paper feed failure due to mechanical damage. Replacing the roll will not fix this. ※ To reiterate, replacing the roll requires removing and installing various parts. ※ I will not provide text-based support for disassembly, replacement, or assembly, as it is difficult. I will try to answer questions to the best of my ability, though... The item will be sent via regular mail to reduce the price.
