    Product Information Feeder setup Feeder setup Packing List The optional paper feeder package contains each of the following items in the indicated quanti- ties. Optional bulk paper feeder PF-8E, 1 Instruction manual, 1 Option The following option unit must be purchased separately in order to install the feeder with the printer.
  • Page 8 Product Information Feeder setup Choosing a Location The feeder will work best if it is installed in a location that is: Level and well-supported: Place the base on a sturdy table or desk. Not exposed to sunlight or other bright light (not next to an uncurtained window). Well ventilated, not too hot or cold, and not too damp or dry: Temperature should be 10 to 32.5°C, ideally about 23°C (50 to 90°F, ideally about 68°F).
  • Page 9 Product Information Feeder setup Pivot down the MP tray on the paper feed unit. Grasp and pull the MP tray upwards until it is removed from the paper feed unit. Retain the MP tray for future use. Installing the Base and the Printer The printer is mounted on the upper deck of the base.
  • Page 10 Product Information Feeder setup Note The table or desk must be larger than the base. Align the positioning pins on the top of the base with the holes in the base of the printer, then slowly and carefully lower the printer onto the base. Make sure that the connector on the base fits squarely into the corresponding connector in the base of the printer.
  • Page 11 Product Information Feeder setup Installing the Paper Feeder Mount the paper feeder onto the rail in the lower deck of the base. The rail is movable and must be pulled out before installing the paper feeder. Pull the rail fully out until it stops. Grasp the feeder by the two handles in the side covers.

    Product Information Paper specifications Paper specifications General Guidelines The paper feeder is designed for use with various special types of print media such as adhesive- backed label, thick paper, envelopes, and post cards, it may not be used to print on paper not sat- isfying the requirements below.
  • Page 20 Product Information Paper specifications of A4, B5, A5, letter size, etc. The legal size paper is not usable with the paper feeder. Since the printer does not recognize the size of the paper currently loaded in the option paper feeder, it assumes that all paper fed from the paper feeder have the legal size (8-1/2 by 14 inches).
  • Page 21 Product Information Paper specifications Envelopes should have the basis weight of 70 to 100g/m (0.16 to 0.22 lb./ream) and up to 4 plies of the paper that is used to construct the paper including all flaps and overlaps. Envelopes should have sharply-creased folds and accurately joined corner edges. Envelopes should have a smooth, uncoated surface.
