If the single sheet delivery mode is selected, photocell 80, upon sensing the trailing edge TE of printed sheet PS together with the selection of this mode, operates platen drive motor 58 to rotate platen 54 upwardly to move printed sheet PS upwardly and rearwardly toward upper hopper plate 66, as best shown in FIGURE 10.
  • photocell 80 upon sensing the trailing edge TE of printed sheet PS together with the selection of this mode, operates platen drive motor 58 to move printed sheet PS first upwardly to move the trailing edge TE upwardly above lower platen feed guide 60 and then downwardly for sequential stacking in lower chamber hopper 30, as best shown in FIGURE 11.
  • printed sheet deflector guide 91 positioned between platen 54 and print wheel 56 guides the trailing edge TE of printed sheet PS toward narrow opening 32 of center wall 26 to prevent the trailing edge TEfrom being caught on print wheel 56, as best shown in FIGURE 11.
  • Printed sheet guide plate 51 guides printed sheet PS with its printed side down through narrow opening 32 of center wall 26 toward lower chamber hopper 30 to collate successive printed sheets of a multiple sheet document in their order of printing in lower chamber hopper 30, as best shown by the dotted lines in FIGURE 11.
  • Front wall aperture 44 provides easy access to the collated printed sheets PS in lower chamber hopper 30; and the generally downwardly and rearwardly extending recessed central portion 42 facilitates the removal of the stacked and collated printed sheets PS.
  • top cover 34 and side doors 38 and 40 are opened to provide easy access thereto.
  • Top cover 34, using detent 33, is pivoted back to lie atop upper hopper plate 66, as best shown by FIGURES 2 and 3.
  • Platen 54 and lower platen feed guide 60 and feed rollers 62 may be readily removed from frame 52 for servicing.
  • the print head and ribbon cartridge assembly may be tilted into the inoperative position for easy access to rotary print wheel 56 without having to remove ribbon cartridge 83.
  • the inoperative position places print wheel 56 approximately 90 degrees away from the operative position adjacent platen 54, as best shown in FIGURE 9.
