• Code: 06-340
• Description: ROS Laser Failure RAP 06-340. The IOT PWB has not detected the ROS laser reaching the operating speed.
• Remedy: Go to Flag 3, connect a service meter to P/J 2 pin 7 and make a set of 5 copies. 0V is measured at P/J2 pin 7 on the IOT PWB during run. Y↓N→The xerographic module is fully home and the front door is fully closed or the front door interlock is cheated. Y↓N→Correct the condition. Go to Flag 1. Disconnect P/J18 from the LVPS. Check the following voltages on the LVPS: • +24V between pins 1 and 2. • +3.3V between pins 3 and 4. The voltages are good. Y↓N→Go to the relevant RAP: • 01B 0V Distribution RAP, refer to the 3.3V return and 24V return. • 01D +3.3V Distribution RAP. • 01G +24V Distribution RAP. Enter the dC330 output code 06-020. Go to Flag 2. The ROS motor gives a distinctive ascending frequency sound, of a short duration (5 to 6 seconds) during transition from standby to run. Y↓N→Go to the 06-020 ROS Motor Failure RAP. NOTE: The ROS must be removed from the machine, to disconnect P/J122 and P/J121. The ROS PWB where P/J122 and P/J121 are connected may not be marked with the correct PJ numbers. P/J122 can be identified as a four way power harness. P/J121 can be identified as a seven way signal harness. Check the wiring at Flag 1, Flag 2 and Flag 3. The wiring is good. Y↓N→Repair the wiring or install new harness PL 6.10 Item 5. Install a new ROS, PL 6.10 Item 4. Go to Flag 4. Check that P/J109 (32-55 ppm) or P/J228 (65-87 ppm) on the image processing PWB is securely connected. If the fault is still present, remove the ROS. Go to Flag 4 and ensure that PJ122 on the ROS is securely connected. If the fault is still present, go to Flag 4 and check the continuity of the ROS data cable ( P/J228 or P/J109 to PJ122). The ROS data cable is good Y↓N→Install a new ROS power distribution/communications harness, PL 6.10 Item 5. Install new parts in the following order: • ROS, PL 6.10 Item 4. • Image processing PWB (32-55 ppm), PL 3.20 Item 3. • Image processing PWB (65-87 ppm), PL 3.10 Item 3. • Perform OF7 IOT PWB Diagnostics RAP before a new IOT PWB is installed, PL 1.10 Item 2.
