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: When extending the fingers manually, to check the sensors, the home sensor operatesfirst, followed by the init sensor. The away sensor operates when the fingers are fully extended.Figure 1 shows the component locations.Enter dC330 code 11-192, support finger home sensor. Note the position of the support fingersat rest. Using a screwdriver, or with a finger, turn the gear wheel shown in Figure 1, down-wards. The support fingers extend to the right as the gear is turned. When the support fingershave extended by about six millimetres, the support finger home sensor changes state. Thedisplay changes from High to Low.Y NGo to Flag 1 and check the support finger home sensor, Q11-192. Refer to:• GP 11 How to Check a Sensor.• P/J402, HVF control PWB.• 11A-171, HVF Power Distribution RAP.Install new components as necessary:• Support finger home sensor, Q11-192, PL 11.140.• HVF control PWB, PL 11.157 Item 2.Enter the dC330 code 11-191 and continue turning the gear wheel. When the support fingershave extended by about 25 mm, the support finger init sensor changes state. The displaychanges from High to Low.Y NGo to Flag 2 and check the support finger init sensor, Q11-191. Refer to:• GP 11 How to Check a Sensor.• P/J402, HVF control PWB.• 11A-171, HVF Power Distribution RAP.Install new components as necessary:• Support finger init sensor, Q11-191, PL 11.140.• HVF control PWB, PL 11.157 Item 2.Enter the dC330 code 11-193, support finger out sensor, Q11-193 and continue turning thegear wheel. When the support fingers have extended by about 105 mm, the support finger outsensor changes state. The display changes from High to Low.Y NGo to Flag 3 and check the support finger out sensor, Q11-193. Refer to:• GP 11 How to Check a Sensor.• P/J402, HVF control PWB.• 11A-171, HVF Power Distribution RAP.Install new components as necessary:• Support finger out sensor, Q11-193, PL 11.140.• HVF control PWB, PL 11.157 Item 2.Make several small sets of prints and observe that the support fingers are extended betweeneach set. The support fingers are extended.Y NRemove the HVF top cover and rear cover, REP 11.1-171. Enter the dC330 code 11-172,support finger motor encoder. Figure 1. Manually turn the support motor encoder disc.The encoder sensor changes state.Y NGo to Flag 4 and check the support finger motor encoder sensor, Q11-172. Refer to:• GP 11 How to Check a Sensor.• P/J402, HVF control PWB.• 11A-171, HVF Power Distribution RAP.Install new components as necessary:• Support finger motor encoder sensor, Q11-172, PL 11.140.• HVF control PWB, PL 11.157 Item 2.Go to Flag 5 and check the wiring and repair as necessary, REP 1.2. Install new compo-nents as necessary:• Support finger motor, PL 11.140 Item 9.• HVF control PWB, PL 11.157 Item 2.Perform SCP 6 Final Actions.AA
