Maintenance: Disassembly Guidelines

Writer Roller/Carriage Assembly

Removal

Remove the power supply assembly following procedures above.

Inside the power supply compartment, disconnect the cable that connects to the
writer assembly.

Open the unit to access the paper compartment. Move the paper size bracket to
the A4 position to expose one of the writer assembly mounting screws.

Remove the screw and return the paper size bracket to the



8.5 x 11 position.

Close the unit and turn it over so the bottom side is up.

Remove the four screws located on the underside of the writer roller/carriage
assembly and lift the writer from the bottom of the unit.

Reassembly

Reassemble the writer roller/carriage assembly by reversing the above procedures.

Trolley Casters

Removal

Remove the MAC 5500 and all loose items from the trolley and then place the
trolley on its side.

Locate the slot under the arrow on the bearing dust cap and using a small blade
screwdriver, pry the cap from the caster to be removed.

Using an Allen wrench, remove the wheel shaft and wheel from the caster.
