Abstract
In order to reduce thermal coupling between diodes in a light emitting diode array for a printing or imaging system which has the undesirable effect of wavelength shift and output reductions, rows (12, 14) of diodes are provided which are separated and inclined to the direction (Y) of scanning movement during a print operation, wherein current pulses applied to the diodes of each row for energization are delayed with respect to one another such that energization and printing occurs in a line perpendicular to the direction of scanning movement.
