OUTPUT 5
MEMO:
- Displays all "?" if "GAP CALIB" is not performed.
- If the value exceeds 1000, 999 is displayed.
1. Checking "OUTPUT 0" and "OUTPUT 1" when media (excluding clear film) is fed
[Check 1]
Check whether the multi sensor performance has degraded or whether the media is compatible with the multi sensor.
When "Media edge (diffuse reflection) gain" is maximum values and "Media edge (diffuse reflection) media output" is 186 or less, an error occurs.
Maximum value of "Media edge (diffuse reflection)" gain: 255
When the multi sensor and media are normal, the following values are displayed:
[Check 2]
Check whether the multi sensor performance has degraded or whether the media is compatible with the multi sensor.
When the difference between "Media edge (diffuse reflection) gain" and "Media edge (diffuse reflection) platen output" is 100 or less, an error occurs.
When the multi sensor and media are normal, the difference is about 300-600.
[Check 3]
Check the effect of external diffuse light.
