TI SR-52 card reader

My SR-52 card reader reads pre-recorded program cards OK, and they go all the way through the card reader. But cards that I write programs to always remain inside the calculator when inserted during the read or write operation. The motor stops short. I have to push them out with another card. The programs get properly recorded onto the card when writing, and properly read into the program memory when reading, but these cards always stop short inside the calculator, both on reading and writing. Any suggestions as to what I can do to fix this. I have already run the head and roller cleaner cards through the calculator. Thanks
