NCU • To check the NCU sensor
sensitivity
• If the "2.2.1 NCU"(P. 48) was
replaced
• Sensor Chk: This is used to check the
NCU (clogging detection unit) sensor
sensitivity.
• Level Adj: Not currently implemented
(used for development)
• Nzl Check: Not currently implemented
(used for development)
• Nzl Chk Easing: Not currently
implemented (used for development)
• Parameter: Not currently implemented
(used for development)

BITMAP • To check bitmap (font) data
stored in the machine
• --- -
SD Card • Not currently implemented
(used for manufacturing)
• --- -
Valve Test • To leave valve open • Ink Valve: ON/OFF
DAS sensor • To check the DAS sensor
sensitivity
• Move the DAS sensor onto white
media and press the [ENTER] key to
confirm that the value is 600 or more.
– If it is not more than 600, clean the
DAS sensor.
