2 | Paper Lift | Check the lift plate assembly, release button, |
| Plate Assem- | button spring, release arm and all related hard- |
| bly | ware for proper operation. Be sure the lift plate |
|
| |
|
| not worn, contaminated or missing. Repair as |
|
| necessary. |
|

|
3 | Paper Empty | Check the paper sensor flag for damage and |
| Sensor Flag | proper operation. Repair or replace as neces- |
|
| sary. |
|
|
|
4 | Paper Empty | Be sure the voltage at |
| Sensor | board is between +4.5 V dc and +5.5 V dc. If |
|
| incorrect, replace the engine board. If correct, |
|
| check the voltage at |
|
| changes from approximately +2.00 V dc to 0 V |
|
| dc as you manually move the sensor flag in and |
|
| out of the sensor. If incorrect, be sure tray two |
|
| cable measures continuity. If incorrect, replace |
|
| the cable. If correct, replace the tray two sensor |
|
| board. |

5 | Second | Be sure the solenoid cable is connected to the |
| Paper Tray | paper sensor board cable and the cable is prop- |
| Solenoid/ | erly connected to the sensor board. |

| Board/Sole- | Disconnect CN9 at the engine board. The volt- |
| noid Cable/ | age measures approximately +24 V dc at |
| Tray Two | |
| Cable | correct, reconnect CN9 and measure the volt- |

|
| be incorrect, check the resistance of the sole- |
|
| noid at the solenoid cable connector which mea- |
|
| sures from 60 to 90 ohms. If incorrect, replace |
|
| the tray two solenoid. If correct, be sure the |
|
| solenoid to sensor board cable measures conti- |
|
| nuity. If incorrect, replace the sensor board and |
|
| cable assembly. If correct, be sure the tray two |
|
| to engine board cable measures continuity. If |
|
| incorrect, replace the cable. If correct, replace |
|
| the tray two sensor board. |
