How do i change the ribbon on my canon MP20D calculator

For accounting offices and stores, calculators that produce a printed paper are indispensable. Canon's desktop or commercial printing calculators use ribbon tape, and you'll need to change the ribbon when it is used up. All Canon desktop and commercial printing calculators use the same method for changing the ribbon.

• Turn off the calculator.
• Pull up on the tab on the far side of the printer cover to remove the cover.
• Pinch together the ribbon lock (the arrow shows you the direction to pinch). Lift the ribbon spools off the shafts and discard them.
• Separate the new ribbon spools. Guide the ribbon tape around the four guiding pegs and set the spools on the shafts. The spools should be peg side down.
• Rotate the spools so the peg at the bottom of the spool goes into the hole of the spool holder. Release the ribbon locks.
• Rotate the spools to make the ribbon taut, keeping the ribbon positioned around the guide pegs.
• Replace the printer cover and turn the calculator on.

Could it be you are using old ribbons? Are you using the correct ribbons?
did you put in the ribbon correct and is the ribbon transported, while it is printing, or is it stuck in the calculator. Just some questions to check out.

I did replace the ribbon correctly. I used a universal replacement. the black part of the ribbon in on the top and the red at the bottom but I am not able to print clearly on the tape. What would be my problem?

There is a lever between the two spools that will flip to one side or the other and change direction of ribbon spools.

remove the printer cover, insert one spool on the left side pin, guide the ribbon though printer and inset other spool on right pin. make sure the ribbon looks like a C with the ribbon coming around the outside of each spool.

Remove the paper tape by pulling it back out of the calculator.

Feel along the back of the calculator right below where you insert the paper tape for a ridge. Gently lift up on this ridge and a plate will lift out of the machine exposing the ribbon.

Make a note to yourself as to how the old ribbon is in the machine before removing the old ribbon. Just gently lift straight up on both of the spools and the ribbon will lift out of the machie.

When you insert the new ribbon make sure that the ribbon is feeding off of the back side of both spools. You can use a small screwdriver or toothpick etc to position he new ribbon to keep the ink off of your fingers. Make sure the new ribbon feeds around the plates on both sides of the machine and it fits behind the roller that has all the numbers on it and that the red portion of the ribbon is on the bottom.

Take the plastic plate that you removed first and insert the tabs in the front underneath edge of the case on the front and gently push the back side of the plate straight down till it smaps into place.

Refeed the paper tape back into the machine and you are finished!

Hope this helps.

Hi there, there are a couple possibilities. First, Remove the cover where the paper feeds out, if there is a ribbon or an ink roller in there it will need replacing. This you can get a staples. The other possibility is, if there is no ribbon or ink roll, it is probably a thermal printer which means is uses a special heat sensitive paper. If this started when you changed the paper, this is most likely the problem. This you can also get at staples!
