Mechanical arms ("feelers" - attached to bellows on each print head
- one arm per color) are calibrated at first filling for full position.
Periodically, these feeler positions need to be recalibrated.
At these times (Air Purge, Ink Filling):
Ink and air are purged from head tanks
Air release valve is opened during filling until prescribed time
Air release valve closes
Ink pump motors run in reverse (momentarily) to create vacuum in
head tank
Optimal arm position is set.
» J017/J019/J021/J023 - Note that this operation is performed two times
each occurrence, not four times, as each pair of channels per dual-
channel head (for the two heads) is done together.
» J018 - Note that this operation is performed four times each occurrence,
not eight times, as each pair of tanks per dual-channel head (for the four
heads) is done together.
