C4696Ć60002 Legs Hardware Kit 1
Situation
In the initial hardware kit for the legs assembly we had the following problems:
1 The screws of the legs get loose when moving the plotter. This makes the unit sway,
giving a perception of weakness.
2 When the units are shipped without disassembling the legs, the screws may come out and
the legs collapse due to the vibration. This problem is affecting mainly dealers and the
trade show units used in the Marketing Centers.
Solution
The screws have been replaced by longer ones and washers have been added. This solution
has been tested and the results show that the sway problem has been solved in customers'
units. However, it is not a good solution for units that are constantly moved or shipped
mounted, like the ones in marketing centers.
To install the new hardware kit (C4696Ć60002) follow this procedure:
1 Verify that the screws of the legs do not have washers installed. If they already have
washers, do not proceed with the following steps.
2 Without turning the plotter upside down, remove the old screws that attach the legs to
the plotter.
