New Spring in Mothra’s Step, the arrival of Monster Zero, and DIY Composer Ribbons munk July 3, 2015 From the Desk of Reverend Munk, Typewriter Repair 101, Typewriter Typestyles/Fonts, Typewriters In The Corral 4 Comments almost out of ribbon – the horror! what will I do? LIES! SII Carts do not fit in a Composer! SII cartridge, way too big, and full of too much tape. Also, feed core is just wrong enough to not work. Too unevenly wrapped. The ribbon develops folds. Solved the problem by cutting up thr snap-on part of the cartridge to rovide a flat surface at the bottom end of the spool core. That worked perfectly.
