摘要:
An ink-jet printer includes an ink-jet cartridge having a flexible circuit connecting to a carriage in a relatively movable but movably constrained relationship. The carriage and the flexible circuit cooperatively define an instant center so that an array of electrical contact pads of the flexible circuit is reliably and repeatably positioned relative to the carriage, while manufacturing variabilities and thermal differential expansions between the carriage and flexible circuit, for example, are accommodated without loss of relative positional control of the array of contact pads and the carriage.

A process for start up of a thermal ink-jet printhead cartridge that includes a sequence of nozzle clearing procedures of increasing severity which are performed in sequence so long as some of the nozzles of the printhead fail to fire ink drops pursuant to ink firing pulses provided to the printhead or until all of the procedures have been performed.
