ABSTRACT:
A segmented flexible heater disposed adjacently to a paper path in a printing machine for heating a recording medium before printing and during printing. The segmented flexible heater includes a curved first portion for preheating the paper and a substantially planar second portion for heating the paper in a print zone wherein the second portion generates heat energy having a temperature greater than the heat energy generated by the first portion. The first portion includes apertures for accommodating drive rollers for moving the recording medium into the print zone area heated by the second portion. The apertures in the flexible heater provide for continuous heating of the recording medium before and during heating. The second portion is preferably at least two printing swaths wide to prevent thermal shock to the portion of the printing medium being printed on.
