Xerox DC250 Style Component Control Codes Xerox Docucolor 240, 250, 242, 252, 260 WorkCentre 7655, 7665, 7675, 7755, 7765, 7775 In Part II of this series, we got into the Diagnostic Mode ("CE Mode"). Lots of good stuff in there, but to use the Component Codes to test motors, sensor, etc, you need to know what each code is. In this month's article, we'll begin to list them… starting with the Input Component Codes. It makes for rather bland reading, but it is one of the keys to being able to troubleshoot & solve problems on these machines… so here goes. With the full Service Manual in hand, you'd be able to read all about getting into the "UI" (User Interface) Diagnostics from the Control Console… and you can read about how to get to the Component Control screen. Unfortunately the service manual stops short of including a list of which codes do what. If you happen to be blessed with access to one of the PWS (Portable Work Stations) with this machine's diagnostic program on it, and you went into the Component Control screen, you would be treated to a full list of codes to scroll through (complete with descriptions). This is not the case if you're in the UI (User Interface) diagnostics from the control console. You need to know the codes to be able to test anything. The process for getting into the UI Diagnostic Mode depends on exactly which model you're working on. For DC240/242/250/252/260: Hold down the '0' button for 5 full seconds and then, while still holding the '0', press 'Start'. A prompt for a password will show up (the "CE Access Number" screen). Use the default password '6789' followed by 'Confirm'. For most WC-7655/7665/7675's (some early ones work like the DC250 above… also probably true for the 7755/7765/7775): Hold down together '*', '#', & 'Stop' until the password prompt shows up. Then use the '6789' default password followed by 'Confirm'. Next press the "Log-in / Log-out' button. Once you're in UI Diagnostic Mode, choose 'System Settings', then choose 'Common Settings', followed by 'Maintenance / Diagnostics'. Scroll down & select: "Component Control". From the Component Control screen, you'll enter the "Chain" (the first 3 digits of the code) followed by the "Function" (the second 3 digits of the code). Press 'Start' to activate the test. For these Input Component Tests, you will be able to see on-screen the status of the component (H for high or L for low)… you can toggle the actuator or otherwise activate the switch or sensor you're trying out and see if the status of the component changes on-screen. Press 'Stop' button to stop the current test. When you're done, press 'Close' to leave the Component Control screen. Below is an abbreviated list of the component codes. There were simply too many codes to include in a magazine article. The ones that are missing were either relating to peripherals such as the finishers, or the description for the component was too ambiguous to be of use. The list is followed by a quick run-down of what some of the acronyms stand for.

Next month, we'll revisit the subject and list the Output Component Codes. Sometime after that the final piece in the puzzle will be the NVM (Non Volatile Memory) settings.
