ABSTRACT:
A printhead cartridge and carriage assembly (10) for use with ink-jet printers is disclosed. The assembly is provided with means (56) for ensuring that an ink-jet cartridge (20) is securely locked in place in a cartridge carrier (12), means (78, 78a, 80, 80a, 82, 82a) for ensuring that cartridge is registered in a given, fixed, repeatable position each time, means (128) for ensuring that the cartridge is spaced from the printing medium (40) a minimum, fixed distance, means (100) on the carriage for maintaining this fixed distance, and interconnect means (84) for connecting a printhead assembly (34) on the cartridge with a microprocessor for controlling the pattern of ink drop ejection. The assembly further includes a preloader assembly (106) for preventing backward rotational pivoting of the carriage about a slider rod (44) associated with a platen (46) of the printer and for urging the carriage toward the medium on the platen. Finally, a dust barrier (132) protects the interconnect means at the contact to the printhead assembly.
