How to use

Turn off the printer and follow the manufacturer’s instructions for safe removal of the spent developer unit. Unpack the replacement developer carefully, avoid touching imaging surfaces, and install it into the designated bay until it seats securely. Power the printer back on and allow the device to recognise the new developer; the printer may perform an automatic initialisation cycle. After installation, run a test print or calibration procedure if recommended by the printer interface to verify correct alignment and colour output.

Usage recommendations

Use genuine Lexmark Unison toner and follow Lexmark’s maintenance schedules to preserve image quality and achieve the stated page yield. Return used developer units through the Lexmark Return Programme to comply with the single-use remanufacture restriction and to ensure proper recycling. Store replacement units in a cool, dry environment and avoid exposure to direct sunlight or extreme temperatures before installation.
