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.

If you had posted what Country you are located in, I could have ran a search to locate someone local to you that has this product in stock. I am located in California. I could give you information on compatible ribbons which are available in my area, but they may not be available in yours and that would not solve your problem.

I would suggest that you stick with the ribbon that is made for your typewriter if at all possible? If you are unable to locate stock in your Country, try ordering the ribbons online instead.

The ribbons are available at Office Depot. They sell the product online and have your ribbon in stock. Here is a link to your ribbon on their website:

Here is a link to a website that sells both the generic and brand name ribbon for your typewriter:

okay; it sounds like you are having trouble with the order of operations. A simple way to fix this and to ensure that you get the right answer is to multiply the 1.8 times 1.8, write it down, clear the calculator, and then do the division using the number you've written down. Sol your new equation will be 70/3.24 = 21.6049

Paper loads into slot at end of machine. After inserting end into the slot (at rear, near power cord connection) press feed button until paper advance thru top.

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.
