Shave all clips and bumps off to make the bottom and sides flat. You don’t have to modify the tops. The plastic is soft enough that it's not too hard.

3m adhesive foam will stick well enough to print immediately. It will become stronger over time, but can still be peeled off (slowly) later, with no damage to the printer.

C. Itoh / Riteman / Amstrad ribbon hack

Preparing the ribbon:

When you buy the ribbons new, they have some clips formed into them that don't fit the DMP-100.
Shave all clips and bumps off to make the bottom and sides flat. You don’t have to modify the tops. The plastic is soft enough that it's not too hard. I use a multitool to break most parts off by grabbing them with the pliers, then clean up a little by shaving with the knife and maybe the file. The fat pin in the center of one of the housings is a bit tough to get with a knife alone, so you may have to use the saw on that.
Put about ¾ inch square of 3M automotive double stick foam tape on the bottom of each housing. Leave the red plastic film on for now.

Installing the ribbon:

Use some alcohol and paper towel to clean the top surface of the steel platforms where the normal ribbon housings go, so they are clean and dry.
Peel off the red plastic film from the housings.
Take the larger housing with the round shape and the bump on top in your Left hand, and the smaller housing with the flat blade on top in your Right hand, and stick them to the steel platforms, butted right up against the inside walls of the printer, and such that the ribbon closest to the front of the machine forms a straight line through the ribbon advance pincher behind the print head. The ribbon that touches the paper will not form a straight line. You should feel a ribbon tension spring compress a little in the right-hand housing, and the ribbon should have no slack. (route the ribbon in front of the print head and through the ribbon advance pincher the same as normal)
3m adhesive foam will stick well enough to print immediately. It will become stronger over time, but can still be peeled off (slowly) later, with no damage to the printer.
