Fusing Assemblies for HP Laser Printers

Does anyone have any used fusing assemblies or maintenace kits for the following HP laser printers?:

HP 5Si – 5000 – 4000/4050 – 4100 – 8000 -8100/8150
9000 – 2100 – 2200 – 1200

I rebuild these units and I am in critical need. We will negotiate a fair payment for them.

If you may have questions on fusing assembly replacement or maintenance kit replacement, please feel free to contact me.
