This SP code monitors and displays the progress of each print head unit during the ink
filling sequence. If the progress of ink filling is interrupted, the machine will know where
to resume filling (and at which unit) after normal operation has been restored. The
following actions can interrupt ink filling:
• Opening any cover that triggers a cover open alert
• Power failure on the power supply circuit
The ink filling operation resumes automatically upon restoration of normal operation
(after close the cover or resumption of normal power supply).
1 H1
Progress of H1 (K1) print head.
[0xFFFF FFFF/0/1]
2 H2
Progress of H2 (K2) print head.
[0xFFFF FFFF/0/1]
3 H3
Progress of H3 (C) print head.
[0xFFFF FFFF/0/1]
4 H4
Progress of H4 (YM) print head.
[0xFFFF FFFF/0/1]
2249 Set Air Detection Flag - Flag Continued Time
In previous GelJet machines there was a lot of bubble formation in the ink sub tanks, and
these bubbles were controlled by an air mixture flag that would trigger a print head
maintenance cycle.
• This flag release (24 hours for older machines) has been shortened to 6 hours after
the initial filling and timed by the RTC (Real Time Clock of the machine).
• Shortening the flag release time with this SP code improves maintenance operation.
However, this SP cannot be adjusted until 6 hours have elapsed after initial filling.
