Why choose the genuine HP B3M78A maintenance kit
Genuine HP part B3M78A, designed for the printers listed below: dimensions, materials and lifetime as specified by HP, maintenance counter reset after installation. Preserves the printer's warranty and service contract.
When to replace it
The printer shows a maintenance message when the part's counter reaches end of life (Reports or Supplies status menu). Replacing it then avoids jams, marks and wear on other parts.

Check the exact reference of your printer (label at the back or Information menu); suffixes (dn, dw, fdw, n) are variants of the same series and use the same consumables.
