Description
Compatible Models: HP Color Laser 150a, 150nw, MFP 178nw, MFP 179fnw, MFP 179fwg.
What It Is: The Drum Unit Reset Chip - the small memory chip mounted on a drum unit/OPC cartridge that tracks its page count and resets it after replacement, distinct from a toner cartridge's own reset chip. Without resetting this chip, the printer keeps reporting the drum as at end-of-life even with a fresh drum unit installed.
Part Number: 119A (source listing states this as both "120A" and "119A" in different parts of its own title - written here as 119A, HP's drum unit number for this exact model family, with the discrepancy flagged for the user to double-check against the physical part before listing)
