How to use

Switch off the printer and allow it to cool according to the printer manufacturer’s guidance. Open the printer cover and remove the spent drum/toner unit following the printer’s removal instructions. Unpack the replacement unit, remove any protective seals or packaging, and insert it into the printer until it clicks into place. Close the printer cover and follow any on-screen prompts or reset procedures recommended by the printer to register the new unit. Perform a test print to confirm correct installation and consistent black output.

Usage recommendations
