Why does my Canon MP49D calculator print light?

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.

How to Change the Ribbon in Canon Calculator eHow

may have print ribbon installed upside down. what happens if you try printing a negative number? if that number prints in black, try turning ink ribbon over

If one of the colors is not printing, it's time to change the twin spool ribbon.

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?

Hi mkline519,

The new ink roller types are EA-781R-BK (Black) and, EA-781R-RD (Red).

To change the ink rollers.
1). Set the power switch to off.
2). Remove the printer cover. The little paper guard or, flap on top.
3). Remove ink rollers by turning each one counterclockwise and, pulling upwards. With the calculator facing you. Red is on the left and, black is on the right.
4). Install the new ink rollers in there correct position's. Simply press them in one at a time and, make sure they are secure.
5).Put the print cover back on.

If calculator prints blurry, the rollers may not be not secure. If you have any questions about this calculator simply post a comment and, I'll respond quickly.

turn it off & back on & that should fix it. the ribbon lift needs to reset.

if you calculkator does not print at all try to move a switch to p or print, and you have a ink roller on the printer

Hi...it appears that the ribbon is on upside down..The black has to be on the top and the red on the bottom. Just switch spools and turn the ribbon over..either that or there is a spring off the ribbon platform solenoid on the right side of the printer just below where the ribbon comes off the spool. If the spring is off or broken the ribbon platform will rise too high and print in red. Remotely the solenoid (little blue thing) could be bad or out of adjustment.
Hope this helps..this is usually all it can be.
