Setup, Compatibility & Care
To install the cartridge, power off the printer and open the front access panel. Carefully remove the existing cartridge and insert the Alpa-Cartridge unit, ensuring it clicks firmly into the slot. For best results, gently shake the new cartridge horizontally before installation to distribute the toner evenly. Always store unused toner in a cool, dark environment away from direct sunlight and extreme humidity, which can affect the toner powder consistency. Ensure that your printer model (B4400, B4500, B4550, or B4600) matches the compatibility list before attempting installation.
