3020503 Ink Leakage Sensor
- Press [Start].
- Check the following items displayed.
Check Point / チェックポイントDepending on whether the installed Ink Supply Unit is an old type or a new type, the screen showing the detection status of the ink leakage sensors will differ as described below.
Whether the Ink Supply Unit is an old type or a new type can be determined by the number of ink leakage sensor connectors connected to the relay board.
For more information, see step 37 of the disassembly and assembly instructions for the unit (Ink Supply Unit (EM-C800 Series)Ink Supply Unit (EP-C800 Series))
For new type Ink Supply Unit
If the following screen appears, all sensor connections and the ink leakage sensors are normal
| Display indicating Normal State | Criteria | |
|---|---|---|
| Sensor Connection 1 | NG | Always displayed as “NG” |
| Sensor Connection 2 | OK | OK: There is no problem with the connection of Sensor 2 NG: There is a problem with the connection of Sensor 2 |
| Sensor Connection 3 | OK |
OK: There is no problem with the connection of Sensor 1, 3, and 4 NG: There is a problem with the connection of Sensor 1, 3, and 4 |
| Sensor Connection 4 | NG | Always displayed as “NG” |
| Sensor 1 | - | Always displayed as “-” |
| Sensor 2 | OK | OK: Sensor 2 is not detecting ink leakage NG: Sensor 2 is detecting ink leakage |
| Sensor 3 | OK | OK: Sensor 1, 3, and 4 are not detecting ink leakage NG: Sensor 1, 3, and 4 are detecting ink leakage |
| Sensor 4 | - | Always displayed as “-” |
| Check Point / チェックポイント |
Sensor 1 and Sensor 4 of the new type unit are connected to the relay board via Sensor 3. |
For old type Ink Supply Unit
If the following screen appears, all sensor connections and the ink leakage sensors are normal
| Display indicating Normal State | Criteria | |
|---|---|---|
| Sensor Connection 1 | OK | OK: There is no problem with the connection of Sensor 1 NG: There is a problem with the connection of Sensor 1 |
| Sensor Connection 2 | OK | OK: There is no problem with the connection of Sensor 2 NG: There is a problem with the connection of Sensor 2 |
| Sensor Connection 3 | OK |
OK: There is no problem with the connection of Sensor 3 NG: There is a problem with the connection of Sensor 3 |
| Sensor Connection 4 | OK | OK: There is no problem with the connection of Sensor 4 NG: There is a problem with the connection of Sensor 4 |
| Sensor 1 | OK | OK: Sensor 1 is not detecting ink leakage NG: Sensor 1 is detecting ink leakage |
| Sensor 2 | OK | OK: Sensor 2 is not detecting ink leakage NG: Sensor 2 is detecting ink leakage |
| Sensor 3 | OK | OK: Sensor 3 is not detecting ink leakage NG: Sensor 3 is detecting ink leakage |
| Sensor 4 | OK | OK: Sensor 4 is not detecting ink leakage NG: Sensor 4 is detecting ink leakage |
| Check Point / チェックポイント |
Sensors 1, 3, and 4 of the old unit are each connected to the relay board. |
