Table 15. MAP 0190: Forms Feed Problems (continued) Step Questions/Actions Yes 36. Run T&D 14 to determine the microcode levels in the Go to step 37. printer. The controller code must be at least at the levels indicated in "Reference Table 12, Minimum Microcode" on page 158, to have the latest sensor threshold algorithms. Is the code level at or above these minimums? 37. Run T&D 11 to tune the sensors. Run T&D 21 to verify correct sensor operation. Go to step 38 on page 126. Does running T&D 11 correct the problem only for a brief time? 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. You have completed this procedure. Chapter 1. Diagnosing Problems 125
