Abstract:
An ink-jet recording apparatus that performs recording by causing an ink-jet recording head, for performing recording by discharging ink, to perform scanning on a recording medium, said apparatus comprising:temperature acquisition means for acquiring a temperature of the recording head; discharge heaters, provided within the recording head, for generating thermal energy for heating ink; driving means for driving said discharge heaters in accordance with predetermined parameters; a first motor for causing the recording head to perform scanning; a second motor for conveying the recording medium; determining means for determining whether at least one of said first and second motors is being driven; driving control means for controlling said driving means in accordance with an output from said temperature detection means; and parameter changing means for changing the parameters of said driving means in accordance with a determination by said determining means as to whether at least one of said first and second motors is being driven, wherein the parameters are set such that the thermal energy generated by each of said discharge heaters is within a range such that ink will not be discharged, and wherein the change of the parameters comprises changing a driving frequency for generating the thermal energy within the range.
