LOADING THE PAPER TRAY

Raise the handle of the paper tray

and pull the paper tray out until it stops.

Adjust the paper guides on the paper tray to the copy paper

width and length. Squeeze the lever of paper guide and slide the guide to match with the width of the paper. Move paper guide to the appropriate slot as marked on the tray.

Paper guide B

Fan the paper and insert it into the tray. Make sure the edges go

under the corner hooks.

Do not load paper above the maximum height line ( ). Exceeding the line will cause a paper misfeed.

Paper guide A

Gently push the paper tray back into the unit.

• After loading paper, to cancel the blinking without restarting copying, press the clear ( ) key. The in the display will go out and the start ( ) indicator will light up. Be sure that paper is free of rips, dust, wrinkles, and curled or bent edges.

•

• Make sure all the paper in the stack is the same size and type.

• When loading paper, ensure there is no space between the paper and

the guide, and check if the guide is not set too narrow causing the paper to bend. Loading paper in these ways will result in document skew or a paper jam.

• When not using the unit for an extended period, remove all paper from the paper tray and store it in a dry place. If paper is left in the unit for an extended period, the paper will absorb moisture from the air, resulting in paper jams. When adding new paper to the paper tray, remove the old paper already

•

contained in the tray. Placing new paper on top of the paper already contained in the tray may result in feeding two sheets at one time.

BYPASS FEED (including special paper)

The multi-bypass tray can be used to feed standard paper, transparency film, labels, envelopes, and other special purpose paper. Paper measuring from A6 to A4 and in the weight range of 56g/m from 105g/m2 to 128g/m2), A4 is the maximum size.)

• The multi-bypass tray can hold maximum of 50 sheets of paper.

(Capacity will vary depending on the type of paper loaded.)

• The original image must be smaller than the paper or media for copying. If the original image is bigger than the paper or media, this may cause smudges on the edges of the copies.

Press the tray select ( ) key to select the multi-bypass tray.

Note for loading envelopes

• Envelopes must be fed narrow side into the feed slot at a time.

• Do not use non-standard envelopes, and envelopes that have metal clasps, plastic snappers, string closures, windows, linings, self-adhesive, patches or synthetic materials. Do not use envelopes that are filled with air or envelopes that have labels or stamps attached.

• Envelopes of which the surface is not flat because of embossing may cause the copies/prints to become smudged.

• Under high humidity and temperature conditions the glue flaps on some envelopes may become sticky and be sealed when copied.

• Use only envelopes which are flat and crisply folded. Curled or poorly formed envelopes may cause misfeeds.

• It is recommended that you perform a test print before performing the actual copy job.

Note for loading thick paper

Copying on thick paper requires higher fusing temperature setting. Set the user program 29 to "2 (High)" when using thick paper. (See page 20 and 21.)

This chapter explains basic and other copying functions. The unit is equipped with a one-page memory buffer. This memory allows the unit to scan an original once only and make up to 99 copies. This feature improves workflow, reduces operation noise from the copier, and provides higher reliability by reducing wear and tear on the scanning mechanism.

If the unit does not function properly during use, or if a function cannot be used, see "TROUBLESHOOTING THE UNIT" (p.27).
