August 20072-109WorkCentre 5687 Family 05-300Status Indicator RAPs05-300 DADH Open RAP05-300 The DADH closed switch detects that the DADH is open during run.Initial ActionsCheck that the DADH magnet is installed and aligned correctly. Refer to Figure 1 (32-55 ppm)or Figure 2 (65-87 ppm).NOTE: The DADH has two magnets. On 32-55 ppm machines, the center magnet activatesthe DADH closed switch, refer to Figure 1. On 65-87 ppm machines, the left magnet activatesthe DADH closed switch, refer to Figure 2.ProcedureWARNINGSwitch off the electricity to the machine, GP 14. Disconnect the power cord from thecustomer supply while performing tasks that do not need electricity. Electricity cancause death or injury. Moving parts can cause injury.NOTE: (32-55 ppm) To get access to the bulkhead connector, remove the user interfaceassembly, PL 2.15 Item 1. To get access to the DADH closed switch, remove the top cover, PL14.20 Item 3, from the scanner module. To get access to the scanner PWB, remove the docu-ment glass, PL 14.20 Item 5 and the scanner PWB cover, PL 14.25 Item 1.NOTE: (65-87 ppm) To get access to the bulkhead connector, remove the user interfaceassembly, PL 2.10 Item 1. To get access to the DADH closed switch, remove the top cover, PL14.10 Item 3, from the scanner module.
