Toshiba 6LK40608000 Drum Cleaning Blade BL-FC556D

Drum wiper blade for high-volume e-STUDIO chassis

The Toshiba 6LK40608000 drum blade is the cleaning wiper that scrapes residual toner from the photoconductor drum after transfer. It carries the Toshiba description BL-FC556D and fits the e-STUDIO 55X8, 65X8, 75X8 and 85X8 families. The blade seats in the drum cleaning unit and presses against the drum surface at a fixed angle.

The polymer edge removes untransferred toner before the charge corona recharges the drum. A clean drum surface prevents ghost images, background scatter and repeat marks on the printed page. The blade profile and mounting holes match the original part, so the cleaning unit keeps its designed contact pressure.

Service life reaches 520,000 pages on the e-STUDIO 55X8, 590,000 pages on the 65X8, 660,000 pages on the 75X8 and 720,000 pages on the 85X8. The same blade serves the 5506AC, 6506AC and 7506AC colour chassis and the 550X, 650X, 750X and 850X mono range. Yield figures assume standard coverage and media, so plan replacement against the machine counter.

Worn wiper blades leave toner streaks, background haze or repeating voids along the page. A hardened or chipped edge no longer contacts the drum evenly, and toner escapes into the cleaning unit. Replace the blade when print quality drops or when the maintenance counter calls for it. Check the drum surface at the same time, because a scored drum destroys a new blade quickly.

Fit the blade with the cleaning unit removed from the machine. Clean residual toner from the housing before seating the new part, and avoid touching the working edge with bare fingers. Confirm that the blade sits flat against the drum across its full width. Run a test print and inspect for streaks before returning the machine to service.
