This calculator often types positive numbers in red plus puts weird symbols at the ends of lines that make no sense. I have searched and searched for a way to correct this and nothing explains how to fix this. I am unable to use this machine. I would never never never buy this again. It is a horrible product. I have been using printing calculators for decades and this is the worst one I've ever had. I will see if it can be returned.

This sounded like exactly what I needed. But the calculator was not in a factory box. In fact the only box was the shipping box. Then the ink cartridge was used since it didn't print very boldly on the paper as you would expect from a new cartridge. The black while faint you could read, but the red is very faint. Looks like they sent me a refurbished calculator at the new price. Of course it's going back. This seller should be ashamed of themselves.

Best calculator ever. I have had one of these for ten years, but mine finally went bad. They last almost forever, and are still available, amazingly enough, so no learning curve when replacing mine! Also, the two-color ink wheels last a long time as well and replacements are still readily available. Recommended machine!

I am changing my review on this calculator. Whether it is the "ink" roller problem or, the calculator problem, this was my 2nd Sharp printer that did the same thing. Would not print clear numbers on tape. I am an accountant and need to run tapes and this does not do the trick for me. I ended up with a Cannon with a spool for the ink and Love it! Canon MP11DX bought off Amazon.

The machine arrived very quickly via free shipping. I bought this to replace an older model Sharp calculator, on which I had accidentally spilled cranberry juice drink. I cleaned it off right away, but this drink has a lot of sugar and/or corn syrup, and some fell down between the keys and gummed up the works. I took the machine apart to see if I could clean under the keys, but it would have been a major undertaking and I don't think I would have been successful. With all that being said, this machine is quieter than my older one, and it has all the same virtues that made me like my old one so much. Particularly desirable is that fact that the display of this machine is brightly illuminated, and the numerals are big enough to be read from a distance. In our office, the calculator sits in a dark valley between a large computer installation and a large printer. If the calculator had a display of black numerals against a gray background we would need an additional lamp just to use the calculator. As an unexpected and very welcome bonus, the machine comes with a rigid transparent plastic bubble that allows a customer to see the machine while it is still in its packaging. Since my wife and I often drink coffee, tea, juice, or wine while working at the computer, I have saved this bubble and will keep it on top of the calculator to protect it from any spills that might occur while it is not being used.
