When replacing the print head cartridge, work on a desk or other flat surface to avoid scratching the light-sensitive print head and transfer roll.

Avoid removing the print head cartridge from the printer before it is time to replace it. Removing and replacing the print head cartridge can cause dirt to stick to the cartridge and deteriorate print quality.

Avoid tilting or shaking the print head cartridge when removing it, as toner may spill inside the printer and cause damage.

To ensure good print quality, keep the print head cartridge level when handling it.

Only use print head cartridges recommended by Brother. Using a print head cartridge that is not recommended may result in lower print quality and unsatisfactory printer performance.

Storage Precautions

Do not unpack new print head cartridges until you are ready to install them. If a print head cartridge is unpacked, put it in its aluminum package for storage.

Store print head cartridges away from direct sunlight under the following conditions:

Ambient temperature range, 0 to 35°C. Humidity range 15 to 80% RH (no condensation). Avoid hot and humid areas.

Avoid storing near magnetic objects such as CRT screens, disk drives, or floppy disks.

Keep out of reach of children.
