ABSTRACT:
An apparatus for adjusting the printhead-to-media spacing in an inkjet printer is disclosed. The apparatus includes a carriage rod that is fixed in position relative to a media support and a carriage for supporting at least one printhead. The carriage has a contact surface that abuts the carriage rod to allow the carriage to be supported thereon and moveable laterally along the length of the carriage rod. The apparatus further includes an actuating means that moves the carriage relative to the carriage rod along an axis transverse to a longitudinal axis of the carriage rod. During the movement, the contact surface of the carriage remains in abutment with the carriage rod to thereby allow the carriage to continue to be supported on the carriage rod. A method of printhead-to-media spacing adjustment, implementable using the apparatus, is also disclosed.
