Table 15. MAP 0190: Forms Feed Problems (continued) Step Questions/Actions 34. As a platen becomes worn from use, the surface can become shiny and more reflective. This shine can be interpreted by the sensors as paper present on the platen. Check the platen for a shiny surface and for cuts and bruises. Is the platen surface OK? Yes Go to step 35 on page 124. No a. Install a new platen. b. If the upper feed roller has not been replaced recently, you should replace it. c. Also replace the bail assembly if it does NOT have 2 blue dots on the right side end cap. d. Run T&D14 (Model A00) or Firmware Information (Models 001, 002, 003) to determine the microcode levels in the printer. Replace if not at or above the levels indicated in "Reference Table 12, Minimum Microcode" on page 158. Run T&D11 to run the sensor tuning algorithm on the new platen surface. If the problem persists, go to step 35 on page 124. Chapter 1. Diagnosing Problems 123
