“The bypass key concept filled the gap left by Xerox in its sales of solid inks. Professor Color identified the gap and created an enterprise to provide value where Xerox couldn't. Their entrepreneurial/engineering skills are right up there with Elon Musk and Steve Jobs.
LOVE the bypass key. The individual ink blocks were all original and in perfect shape (no chips or chunks broken off). This is not an accident, it is a direct result of their care in packaging (see photo).”
“I have been using Professor Color for my replacement Color Qube inks since I purchased my printer. You just can't beat the quality and price, the bypass key can be a bit tricky, but support is available if you need it.”
“We found professor color after we purchased the COLOR QUBE 8580. The ink cubes are half the price of the Xerox originals.
They work great. This time I had a 13% off offer which made the cost even less. Customer service was great,. Order shipped fast. One draw back is the bypass key, sometimes it takes many tries for it to work. I have even occasionally turned off the printer and just loaded everything up and it has finally worked Will keep purchasing from professor color.”
“The ordering process is wonderful. Very easy and quick.
Good shopping cart process.
None of this would matter if it wasn't a really good product. It is.”
“Your products are so awesome they are ridiculous!! I have cycled through 8 sticks EACH of Cyan, Magenta, Yellow, and maybe 11 or 12 sticks of Black, and the printer continuously functions with NO hiccup whatsoever. The bypass key is a breeze to work with! The only thing better than the ink sticks would be your customer service, just plain FAST & FRIENDLY! Please do not discontinue making these ink sticks and keep your STAFF awesome!”
