: We have a similar model at home that was working well until one day my son put a piece of paper scrap into the paper tray. We didn't know and went ahead to print, and then it showed a paper jam error. However, we couldn't find any paper jam with the front and back covers opened. Is there still hope? I couldn't find any answers on Google or any disassembly videos... 我家有一台类似型号，本来用的挺好的，有一天儿子放进去一个纸屑在纸盒里，我们不知道直接打印，然后就提示卡纸，但是前后盖打开都找不到卡纸，请问还有救吗？谷歌找不到答案，也找不到拆机视频……
