GREENCYCLE 4-Pack Compatible HP 134A (W1340A) Black Toner — Fits M209dw M209d M234dw M234sdn M234sdw (Not for M209dwe/M234dwe/M234sdne/M234sdwe)

Item: GREENCYCLE 4-Pack compatible toner cartridges — replacement for HP W1340A (134A) Black. Compatibility: Designed for use in HP M209dw, M209d MFP, M234dw, M234sdn and M234sdw printers. Do NOT buy this product if your printer model is M209dwe, M234dwe, M234sdne or M234sdwe — these models are incompatible. Important setup notes: To use these non-OEM cartridges correctly, disable the printer’s "Automatic Update" feature. Updating the printer firmware to the latest version can cause the cartridge chip to stop being recognized, rendering the cartridge unusable. Also note that printers activated with HP+ service should use genuine HP toner cartridges. Chip and toner-level behavior: The cartridge chip does not report remaining toner, so you may receive a "cartridge low" message on your computer after installation; select skip/continue to keep printing. Because the chip does not display toner level, the indicated remaining pages may not reflect the actual number of prints. Yield and quality: Each W1340A cartridge yields up to 1,100 pages (based on 5% coverage of Letter size Paper). All cartridges go through rigorous quality checks to ensure printer compatibility and consistent print results. Performance: Easy to install and formulated to resist fading, smudging, and blurring for dependable black output. After-sales support: We maintain a professional, reliable customer service team — if you have any questions or encounter problems, contact us and we will respond promptly to help.
