Abstract
An electrophotographic printer in which toner is printed and fused and the paper thereafter folded and stacked. To avoid toner stick a blower blows cooling air between adjacent folded sheets. The blower may be mounted on a horizotnally slidable paper guide. The stacker table may be lowered so that the top of the stack is maintained at the same height or the blower may be moved vertically in response to the output of a sensor detecting the top of the folded stack.
