About the FI-1000
HP FI-1000 Print Engine
”Bar in Box” (BNB)
The 1170 printer utilizes an HP FI-1000 print engine. The printbar and ink delivery system in this engine are contained in an assembly known as the Bar in Box as shown below:
The Printbar is made up of 14 individual dies as shown below:
Each one of these dies are made up of 4,224 nozzles or 1,056 for each color channel.
The average drop volume is 10pl for black and 8.5pl for cyan, magenta, and yellow. For pigmented based ink a larger nozzle size is usually required so that blockages do not occur at the nozzle.
When the print bar reaches its end of life, the entire Bar in Box is replaced. It is not possible to replace the print bar or individual dies on the print bar or any other parts in the Bar in Box assembly.

What Is Thermal Inkjet?
From Wikipedia:
To eject a droplet from each chamber, a pulse of current is passed through the heating element causing a rapid vaporization of the ink in the chamber and forming a bubble, which causes a large pressure increase, propelling a droplet of ink onto the paper . The ink's surface tension, as well as the condensation and resultant contraction of the vapor bubble, pulls a further charge of ink into the chamber through a narrow channel attached to an ink reservoir. The inks involved are usually water-based and use either pigments or dyes as the colorant. The inks must have a volatile component to form the vapor bubble; otherwise droplet ejection cannot occur. As no special materials are required, the print head is generally cheaper to produce than in other inkjet technologies.
