A Z-fold paper elongated guide having a width approximately the with of Z-fold computer paper is positioned at the exit of a platen/printer carriage interface in a keyboard-operated computer printer or integrator. The guide not only guides printed-on paper sheets to a printed-on paper storage bin or surface but allows Z-fold paper sheets to be hand directed forwardly toward the computer keyboard for floor storage of the paper in front of the printer. A pair of hump-like rails extend on the top surface of the guide to open up the angle of repose between adjacent Z-fold sheets when the sheets are being reversed in driven direction so as to be transported back through the platen/printer carriage interface. The rails are sloped upwardly in a rearward direction at about 13 DEG and extend to a position juxtaposed to but not touching a transverse rear tear edge of the guide. The rails open up the angle between the folded sheets as they approach the tear bar edge so that a sharp acute angle crease is not formed which would otherwise would tend to hand-up on the guide tear edge causing jamming or unwanted tearing of the Z-fold sheets.
