HP 181A Black Original Laser Imaging Drum (W1816A)
HP 181A (W1816A) is a black imaging drum designed to work with HP Laser 300 and Laser MFP 300 series devices, such as HP Laser 303d/303dw and Laser MFP 323d/323dnw/323sdnw (model lists vary by region). Rated for an average of 10,000 pages under ISO/IEC 19752 continuous printing conditions, the drum provides a significantly longer service life than the corresponding 181A toner cartridge, which is swapped more frequently. As part of the imaging system, the drum ensures that every page receives consistent, sharp black text and graphics, maintaining print clarity and density over thousands of impressions.
Being an original HP part, the 181A drum is tuned to work precisely with HP toner formulations and device firmware, helping to minimize background shading, ghosting, and other print defects that can arise from worn or third‑party components. The unit is user‑replaceable: once the printer indicates that the drum is near end‑of‑life, it can be removed and replaced with a new W1816A without special tools, keeping downtime low in busy office environments. HP backs the drum with its Premium Protection Warranty, warranting it to be free from material and workmanship defects for the life of the cartridge.
