• Up to 50 sheets of standard copy paper can be set in the bypass tray.
• Be sure to place A6, B6 or 5-1/2" x 8-1/2" size paper or envelopes horizontally as shown in the following diagram. 

(When using the printer: Same as the direction for the A4 size paper, etc)

• When loading envelopes, make sure that they are straight and flat and do not have loosely glued construction flaps 

(not the closure flap).

• Special papers except SHARP recommended transparency film, labels, and envelopes must be fed one sheet at a 

time through the bypass tray.

• When adding paper, first remove any paper remaining in the tray, combine it with the paper to be added and then 

reload as a single stack. The paper to be added must be the same size and type as the paper already in the tray.

• Use SHARP-recommended transparency film.
• Do not use paper that is smaller than the original. This may cause smudges or unclean images.
• Do not use paper that has already been printed on by a laser printer or plain paper fax machine. This may cause 

smudges or unclean images. 

Do not use the following envelopes. Envelopes misfeed, and smudges may result.
• Envelopes with metal clasps, plastic hooks, or ribbon 

hooks

• Envelopes closed with string
• Envelopes with windows or backing
• Envelopes with an uneven front surface due to 

embossing

• Double-layer envelopes
• Envelopes with an adhesive for sealing
• Hand-made envelopes
• Envelopes with air inside
• Envelopes with creases, fold marks, torn or 

damaged envelopes

• Envelopes with an incorrectly aligned corner gluing 

position on the back cannot be used as creasing 
may result.

• Print quality is not guaranteed in the area 10 mm (13/32") around the edges of the envelope.
• Print quality is not guaranteed on parts of envelopes where there is a large step-like change of thickness, such as 

on four-layer parts or parts less than three layers.

• Print quality is not guaranteed on envelopes with adhesive for sealing.
