Removed and reinstall the Daisywheel. Inspect the ribbon and lift-off tape to eliminate interfering with Daisywheel spinning. Make certain the daisywheel has no bent spokes. Type slowly while carefully watching the hammer come to rest after printing. If you see the hammer moving towards the paper after a print cycle, the hammer is probably causing the Daisywheel to lose homing and will need to retimed or have the hammer cams assembly replaced.
