ABSTRACT:
An office writing machine has sheets fed to the platen (10) from a supply stack and correctly aligned at the print point by feeding the leading edge of the sheet past the contact line between the pressure roller (17) and platen. The platen is then reversely fed at least until the sheet leaves this contact line, at which point its precise position is known. Subsequent forward rotation of the platen advances the sheet exactly to the print point.
