| FRU | Action |
|---|---|
| Operator panel (LCD) Controller card Warning: Do not replace the operator panel and controller card at the same time. Each card contains the printer settings. When either of these cards is new, it obtains the settings from the other card. Settings are lost when both are new and replaced at the same time. |
Lights If the LCD does not come on, open the controller card cage and locate the operator panel connector at J3. Make sure the cable is properly connected to the controller card and the controller card has input voltage to it. With the printer on, verify the following without disconnecting the cable: • Pins 1, 3, 5, and 6—3.3 v • Pin 2—5 v • Pins 4 and 7—GND If these are correct and the operator panel is not functioning, replace the operator panel. If any are incorrect, see “Controller card service check”. |
| Buttons If the buttons do not respond, replace the operator panel. There is no test or repair for the faulty switches. |
Paper feed service checks
Paper jam error indication during POST
| FRU | Action |
|---|---|
| Fuser (exit sensor) | If the exit sensor flag, which is visible at the back of the fuser, is in any position other than vertical, the printer will display a paper jam. Make sure the flag is operating freely. Replace the fuser if the sensor is damaged. |
| Input/duplex sensor Manual feed sensor |
Make sure the input paper feed sensors are working properly. A stuck or incorrectly installed sensor causes a paper jam indication. |
Media picks during POST and/or continuously
| FRU | Action |
|---|---|
| ACM Manual feed clutch |
Check the ACM clutch for wear. The solenoid interacts with the clutch to control the motion of the pick tires. If the ratchet teeth of the ACM clutch assembly are worn or broken, the solenoid may not stop the ACM from rotating. Replace the ACM clutch assembly if necessary. Check the manual feed clutch for damage. |
