After replacing the Flash-Memory IC on a 42xx series library, close the Drive
Access Hatch, then fasten it by turning the two 1/4-turn fasteners clockwise. On
44xx and 46xx series libraries align the Drive Access Panels three or four (model
dependent) 1/4-turn fasteners with the corresponding receptacles on the rear
panel, then fasten it by turning the 1/4-turn fasteners clockwise.
