Couldn't find a manual or user guide. The closest I got were two pages, one with the calculator, and one with the group of calculators that explains some of the functions.

If you have a specific questions, please ask.

How do you change ink on a canon p20-dh 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.

When I print the numbers come out faded, I changed the ribbon is there a way to fix this?

Your ribbon is not seated properly. I would look to make sure you have fed it through all of the guides properly. If this is not a snap in cartridge then I would make sure that the ribbon is feeding the right way and is not upside down.

Printing is very faint. How to change or add ink printer device.

This is most likely a ribbon impact system. Any office supply store should have the ribbon you need, with information on compaitability on the package.

Remove the paper roll and gently but firmly pry on the bezel surrounding the paper exit path. Examine the sides of the ribbon casing for any clips or fasteners.

Replacing inking roller/ribbon?

i had a problem with this as well and found a user manual online. I thought the whole thing came out but it doesn't. If you pull up on the little red thing on right and then the black one on the right you have it. Imagine that! That's all that you change. Then just put some new ones in and your good to go.
