SOURCE: Calculator is stuck in Binary mode

Try this. Press MODE and then number 1 ... This worked to me. And then with DRG you can change to DEG, RAD or GRAD ... I hope I helped :)

There is a tab button that controls the amount of decimal places you would like. press tab and it will change to 0-2-3-4-A-F showing on the bottom of the screen.

It works. :-)

Press the "calendar/clock" button to display the calendar. Then press the "=" sign to get the display to flash and you can enter the numbers for the date. Press the "=" sign again and you have set the date.

Press the "calendar/clock" button once or twice to display the clock. Then press the "=" sign to get the display to flash and you can enter the numbers for the time. Press the "X" button if you need to change the AM to PM or PM to AM. Press the "=" sign again and you have started the clock. Do this again if you need to start the clock again at zero seconds.

SOURCE: How do you load paper into the printing calculator?

Cut paper at a 45 degree angle and load into back slot with angle (apex) of paper to the right of machine when facing it. Be sure to push it thru when loading. You should see tip next to calculator number wheel. Hit the additon sign several times to advance. You may need tweezers to pull paper thru if it doesn't advance by itself.

Why does my Canon MP49D calculator print light?

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.

E shows on left of screen with 0 on right hand side. I can't get it to respond to any prompt.

sounds as if your calculator has registered a number to large to display. this can be done in either the normal calculating mode, or in the memory calculating mode. i will help with both scenarios.

for normal calculating mode:
try pressing the CE button and holding for about a half a second. the E should disappear and calculating function should resume.
if that doesn't work, try disconnecting power supply for a few seconds, then reestablishing power and hit CE

for memory calculating mode(there will be a M on the screen as well if this is the problem)
press either the CE or MC/MCE button for a half second. this should return normal function.
if that doesn't work, try the power reset as described above.

Calculation Wrong

Are you getting this wrong result both on the display and on the printout?

If it's just the display, I'd be tempted to suggest that you've got some bad display elements. Try multiplying 1111111.11 by 9. Do you get all nines, or do some threes show up?

I cannot find a manual for the MP49D, so am using that for a similar calculator.

With the calculator turned on, press the time/calendar button twice. Now press and hold the "time set" button for three seconds. The display should show hours and minutes with the first character blinking, followed by an A or a P. Key in the time (if necessary to change it) using the number buttons, and press the AM/PM button to select A or P. When done, press the "time set" button again, then press the On/Clear button to return to calculation mode.
