Abstract
A printing device has paper feed devices upstream and downstream of a printing station. The downstream paper feed devices uses pairs of pressure feed rolls which frictionally feed the paper when received. A tapered guide channel positioned in side by side relation with the pair of feed rolls comprises a stationary guide plate and pivotable guide plate with guide surfaces designed to collapse any curl in the leading edge of single or multilayer paper. A spring maintains the pivoted guide plate in operating position with a predetermined spring force which opposes deflection by the leading edge of the paper but allow deflection due to paper generated forces exceeding the predetermined spring force.
