PT-E300 labels come out blank after removal of stuck cartridge

The printer has a stuck cartridge, I removed it. A spring and a roller were found dislodged. I pushed the roller back into its bracket but the spring didn’t go back all the way. I couldn’t see how to stow the tail of the spring. As the head still moved in and out; I trimmed the spring so the cartridge wouldn’t get stuck again. Now the PT-E300 will see the cartridge and will “act” like it’s working. The label comes out blank. I have tried a new cartridge with the same results.
