Chapter 7
Maximum value of "GAP gain": 255
Maximum value of "GAP current value": 320
When the multi sensor and media are normal, "GAP gain" is about 30-250; "GAP current value" is about 200.
[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.
- Press the key or key to switch the ink color.
- AE:A-EVEN row, AO:A-ODD row, BE:B-EVEN row, BO:B-ODD row
12) MEMORY CHK
13) HEAD CNT CHK
Confirms the contact status of the printhead.
e) REPLACE
1) CUTTER
This mode is for replacing the cutter.
f) COUNTER
