Amano NS5100 and CP3000 time clock ribbon
Ink color: Indego Black.
This is the only ribbon that will work with the Amano CP3000/5000 clocks.
The standard PIX ribbon is not designed for that much use, at those speeds.
The ribbon is all BLACK.
There are differences in the wearability of the plastic bearings, and also, the most obvious difference:
4x more prints than a standard PIX ribbon.
Another difference is that the ink is different.
A PIX ribbon's ink will not be recognized by a CP3000 or CP5000.
The NS5100 - CP3000 ribbons have an ink resevoir.
This is the raised area in the cartridge.
