Adjustments and Tests18313. Install the ribbon cartridge. (Refer to the User’s Manual.)14. Return the printer to normal operation (page 155).Hammer Bank Power Cable Shorts TestThis test determines if the hammer bank power cable is shorted.1. Prepare the printer for maintenance (page 154).2. Cabinet Models: Remove the paper path (page 222).Pedestal Models: Remove the top cover assembly (page 204).3. Disconnect hammer bank power cable connector P105 from J105 on thecontroller board. (See Figure 46, page 262, item 10.)4. Attach or hold the common lead (usually black) of an Ohmmeter to theshuttle frame.5. At the hammer bank power cable plug (P05) on the shuttle terminatorboard, touch each of the 10 pins with the positive (usually red) meter leadand test for shorts to ground. If you find any shorts to ground, replace thehammer bank power cable.6. Disconnect the common meter lead from the shuttle frame.7. Check the hammer bank power cable for shorts by checking pin-to-pin:touch pin 1 with one meter lead and pin 2 with the other meter lead. Ifthere is continuity, it means there is a short. (Continuity is defined as areading of less than 1 Ohm; in other words, very low resistance.) Repeatthis process until you have tested all the pins in the cable. If you find anyshorts, replace the cable.8. Connect hammer bank power cable connector P105 to J105 on thecontroller board. (See Figure 46, page 262, item 10.)9. Cabinet Models: Install the paper path (page 222).Pedestal Models: Install the top cover assembly (page 204).10. Return the printer to normal operation (page 155).
