Ink-jet printer for printing on cards

摘要

An ink-jet printer includes a printing station for ink-jet printing on a thermoplastic card includes a printhead coupled to a reservoir containing an ink comprising: a medium of a low-boiling organic solvent, an auxiliary solvent of a high-boiling organic solvent, and a coloring component soluble in the medium. A support carriage supports the card and is drivable between a first position in which the carriage does not face the printhead and a second position in which the carriage faces the printhead. A driving motor moves the carriage between the first and second positions along a guide member interposed between the printhead and a reference member to prevent ink ejected by the printhead from reaching the reference member. A detection device mounted on the carriage detects the reference member and generates a signal used by a control unit to regulate the driving motor.

1. An ink-jet printer for printing on cards, comprising:
a printing station for ink-jet printing on a card made of thermoplastic material, said printing station including at least a printhead and a reservoir coupled to the printhead and containing an ink comprising: a medium consisting of a low-boiling organic solvent, an auxiliary solvent consisting of a high-boiling organic solvent, and a coloring component soluble in said medium; a support carriage adapted to support said card, said carriage being drivable between a first position in which said carriage does not face said printhead and a second position in which said carriage faces said printhead; a driving motor active on said carriage for moving the said carriage between said first and second positions; a guide member for said carriage, the carriage being movable along said guide member between said first and second positions; one or more reference members associated with said guide member, the guide member being interposed between said printhead and said one or more reference members to prevent ink ejected by the printhead from reaching the reference member; a detection device mounted on said carriage, said detection device being adapted to detect said one or more reference members and generate a corresponding main signal; and a control unit, connected with said detection device for receiving said main signal and regulating said driving motor according to said main signal.
