GREENCYCLE 134A Black Toner Cartridge 4-Pack 1100 Pages

Greencycle 134A Four-Pack Black Toner

This four-pack of compatible black toner cartridges replaces HP 134A W1340A supplies for LaserJet M209dw and MFP M234 series printers. Each cartridge is new and includes a smart chip for printer recognition. The set suits offices or home users who print regularly and want a ready stock of black toner. Buyers who need colour output or higher-capacity cartridges should look elsewhere.

Consistent Output Over Long Runs

Every cartridge is rated at up to 1100 pages at .05 coverage on Letter paper, and the chip monitors depletion steadily across the full yield. The toner powder, OPC drum and roller are built to maintain sharp text and graphics from the first page to the last without sudden density drops. Actual yield will vary with graphics density and environmental conditions, but the design avoids the early fade common in lower-grade refills.

Straightforward Installation With One Common Pitfall

Installation follows three steps: shake the cartridge horizontally to distribute toner, remove the transparent or orange seal completely, then insert the cartridge into the printer. The most frequent issue is leaving a fragment of the seal on the cartridge, which blocks toner flow and causes light or blank pages. Ensuring the seal is fully removed before insertion prevents this problem.
