REMOVING THE FUSING UNIT

CAUTION
• To prevent electrical shock, switch off the main power switch and
disconnect the power cord from the power source.
• Disconnect all other cables (USB, network, etc.) if they are connected.
• The fusing unit becomes extremely hot during operation, so to prevent
minor burns, switch the machine off and allow it to cool for at least 30
minutes before you remove the fusing unit.
• The fusing unit weighs approximately 14 kg (30.9 lb.) so handle it
carefully when you remove it to avoid dropping it and causing damage or
minor injuries.
Important
• Confirm that the replacement fusing unit is the correct type for the machine.
• A fusing unit with a black top is for the B234/D101 (90 ppm) or B235/D102 (110
ppm).
• A fusing unit with a yellow top is for the B236/D103 (135 ppm only).
• If you install the incorrect fusing unit for the machine, the machine will display a
message and the machine will not operate until a correct fusing unit is installed.
