I have tested two brand new machines. 1. After the brand new machine is initialized with a random original ink cartridge, everything is normal when printing photos. 2. After writing the chip free firmware, print the photo, half the way through, and report an error of 9d. All the lights on the machine began to flash. I would like to say that I have already tested two new xp 55, which cannot be a problem with the machine. This is the issue that occurred after writing your chipless firmware. After the problem occurred, I wrote the latest firmware on the XP55 official website and the printing was still normal without any issues. What I want to say is that as long as you write your chip free firmware, there will be an error. How to get resolved. Please provide me with a solution.
