| Description: | Fuser Error |
| Remedy: | Fuser is too hot during printing or when printer is idle. 1 Fuser lamp (incorrect lamp/ 925 Service Error) Install the correct voltage and wattage lamp or fuser assembly. See “Fuser assembly removal”. If the correct fuser lamp is installed and the 925 error remains, the fuser may have reached standby temperature too quickly. Check that the line voltage is not exceeding the maximum rating for the printer. 2 Fuser lamp fuser top cover assembly Observe the lamp through the left side frame. If the lamp does not come on, do the following: • Remove the redrive assembly. • Remove the fuser assembly, disconnect the LVPS to fuser AC cable from the fuser assembly, and remove the fuser. See “Fuser assembly removal” • Verify that the lamp is installed correctly. If correct, check the continuity of the fuser top cover assembly by verifying the lamp contacts on the right contact assembly. If incorrect, check continuity of the fuser lamp. If incorrect, replace the lamp. If correct, replace the fuser top cover assembly. 3 LVPS LVPS to fuser AC cable CAUTION: When taking measurements for AC power, observe all safety precautions. Measure the AC line voltage between the two connectors on the fuser end of the LVPS to fuser AC cable. If the voltage is incorrect, turn the power off, and remove the LVPS. Measure the AC line voltage between pins CN1-1 and CN1-3 on the board. If correct, check the continuity of the LVPS to fuser AC cable. If incorrect, replace the cable. If the AC line voltage at CN1 is incorrect, check fuse F2. If the fuse is blown, replace the fuse. If the fuse is not blown, replace the LVPS assembly. |
