Hi,In order to subtract, you input the number you're subtracting from followed by the plus sign. Then put in the number you are subtracting followed by the minus sign.

I'm not so sure what your doing. With mine you put in the large number and hit the + key then put in your lower number had hit the - key and to get he answer hit the * key. Example: 500 plus key, 250 minus key, star key to get the answer = 250 I hope this helps you.

Look at it like a piece of paper. For instance, if you want to subtract 20 from 100, you have to write down 100 first - right? The same principle applies here. First clear anything you have in there, then: enter 100 > hit plus sign > enter 20 > hit the red button above the plus sign. Youe screen should now read 80. Hope this helps!

I have not had that problem maybe it is how you key in data. Example: put in $45.00 hit + hit 20.00 (number you want to subtract) hit - and answer $25.00 will appear on screen. I use the print option, middle slide on right (4/5) and +023F on + (left position)

I have printed in only black and white. Just now, I removed the 3 color cartridges, and it would not print. May be missing something, but I think all the cartridge slots must be filled.

When I bought mine, it was included with the calculator. Canon doesn't supply one with their calculator anymore? That is not good. Especially for that machine with over 600 functions.

No it does not. The rate of conversion changes daily so I doubt any calculator will do this. You need a computer program.

The one that i have is not working either, the paper is not rotating at all, i still have it but purchased a canon, that ive had no issues with!

It's surprisingly easy: slide off the cover (in front of the aperture roll, on top), pop out the used cartridge, press in the new one until it clicks. Here's a link to the instructions, look on page 4: http://www.manualslib.com/manual/405512/Canon-P170dh-Desktop-Calculator-12-Digit-Fluorescent.html?page=4#manual

No, print is standard size... not sure if there is anything out there with a bigger print size, but the calculator is great.

Mine did that at first but it said continue I think and when I pressed that it went ahead and left me use it. Good luck, my printer is a Epson XP310, if it gives you a warning and offers any other answer click on that and see what happens. Linda

Sorry, I don't know. I have a PC.. BUT I also did not keep the CANON Pixma. I had been looking for an all-in-one printer, and this didn't have a fax.

It most certainly is NOT multi functional. I ended up returning mine as the toner cartridges would not register. They have supposedly fixed this issue but a heads up in case you have that same probelm, just call the customer service people. Other than that, great printing, very clear and love the duplexing.

I haven't used a 170 in a while, but I think most Canons are the same. Pinch the two sides of the roller holder slightly and slide the roller toward the back of the calculator. Doesn't look like it will pinch, but it does - just enough. You WILL get ink on your fingers, can't be avoided. Take the old one out the same way, just grab the outermost sides of the ink unit, squeeze GENTLY and pull up and toward you.

It will but not automatically. If you select duplex printing it will print the odd numbered pages then ask you to put the paper back in upside down to print the even numbers on the back.

There is a fix, I found it on another site here is linkhttp://www.fixya.com/support/t5863024-printer_canon.I tried it and it worked. The two white tabs had one a little more in than the other so I had to just slightly pull a little on the shorter one which came in line with the other.

My Canon does everything and it does not say print anywhere, I just hit the black or color button.

Yeah, they don't do that, you have to go to this link http://www.printshop.com/user-guide/35.aspx and it must be said... they are STILL working out bugs on that piece of... software

It uses tape that is half red and half black in colors. It uses a standard type tape, and if I understand what would be a 2-ply tape, I have to say that it does not use a 2-ply tape. But I have to say that I am no expert in this area. My only problem with this calculator is that I have not discovered a way to change the print-out to a standard [ $1,2345.67 ] readout. If anybody knows of a way I would love to know how to do it. It isn't covered in the owner's manual.

I never found out as I could not get it to print at all. In addition to not printing, it would not scan or fax and the software/instructions were unintelligible. After fighting with it for three days, I returned it and replaced it with a Brother MFC-7860 DW. The Brother is more expensive, but it took only seven minutes to set up (wirelessly, too!) and it works perfectly. Maybe it was me and not the Canon, but the Brother was so easy......
