[Check 2]
Check whether the multi sensor performance has degraded or whether the media is compatible.
When "Density gain" and "Density current value" are maximum values and "Density media output" is 168 or less, an error occurs.
Maximum value of "Density gain": 255
Maximum value of "Density current value": 245
When the multi sensor performance and media are normal, "Density gain" is about 5-100; "Density current value" is about 200.
10) NOZZLE CHECK
Checks for non-discharging nozzle with head management sensor.
11) NOZZLE INF
Displays the result of non-discharging nozzle check performed with "NOZZLE CHECK" by nozzle row of each ink color.
