The solution is usually very simple, join the ribbon with a small piece of sellotape and wind some of the ribbon onto the take up spool. The take up spool is where the used ribbon is stored. You may lose a print or two but when the printer has acclimatised to the normal ambient temperature your printer will continue to work. Drying the paper roll may accelerate this process which usually takes 30-60 minutes. The simple solution is not to leave the printer in a cold place before using it.
