Abstract:
The present invention provides a simple high-capacity ink supply device as an ink supply system comprising two ink tanks, that is, an on-carriage ink tank integrated with a print head and a replaceable supplementary ink tank. The center value of the supplementary ink tank in the height direction is disposed H mm below the print head. When the width in the height direction thereof is ±h mm from the center value, that is, 2h mm, if the allowed negative pressure variation of a liquid chamber connected to the print head is -(P±p) mmH20, h ≤ p and |P-H| ≤ p are set so that the ink can be sucked up from the supplementary ink tank into the on-carriage ink tank just with the allowed negative pressure.
