3. Hopper mechanism3-4. Loading the documents
3-1. General view1) Make sure that the documents are of suitable size and thickness, and
free from creases, folds, curls, wet glue, wet ink, clips, staples and
pins.
2) Place documents face down in the hopper.
i) Adjust the document guides to the document size.
ii) Align the top edge of documents and gently place them into the
hopper. The first page under the stack will be taken up by the feed
roller to get ready for transmission.
NOTES: 1) Curled edge of documents, if any, must be straightened
out.
2) Do not load the documents of different sizes and/or
thicknesses together.
Fig. 2
The hopper section contains document guides that are used to adjust
the hopper to the width of the original document. This ensures that the
original feeds straight into the fax machine for scanning.
Document width: 148 mm to 216 mm (A5 longitudinal size to Letter
longitudinal size)
NOTE: Adjust the document guide after setting up the document.
