HP 1022n Paper Tray Repairer

When the paper tray of your laser printer breaks, you can use this model or modify it slightly to ensure that your printer can control the margins normally. This model is modeled using SolidWorks, and the length of the model is just right to allow the door to close. The file also has a PDF file that can be used to detect the margins. However, I changed the file to a txt suffix in order to upload it. Please change the txt file to a .pdf suffix yourself. (I'm sorry, this website does not allow me to upload PDF files, so I have no choice but to do this.)
