36OKIFAX 4500BASIC OPERATIONSPreparing Documents• Try to use good quality documents for your transmissions.Documents that are typed or created in felt-tip black ink onwhite (or light) paper work best.• Do not send documents which are not rectangular.• Never use documents that have wet or sticky surfaces,wrinkles, staples or paper clips. However, your fax machinecan transmit documents that have been subject to normalwear, such as documents with staple holes, letter folds andminor corner folds.• If you are not sure how a document will fax, try making acopy first on your fax machine (load the document facedown and press the COPY key).• If your documents are very creased, torn, or crinkled, makea copy on a photocopier and send the copy instead. Youcan also use a photocopier to enlarge or reduce documentsbefore sending.Document SizeAll documents must have a minimum width of 148 mm and aminimum length of 128 mm. Documents cannot be wider than216 mm or longer than 356 mm.Note: If you often have documents longer than 356 mm,your dealer may be able to adjust your fax machine toscan and transmit documents up to 1500 mm in length.Please be aware that adjusting the length setting to 1500mm cancels detection of multiple document misfeeds.Multiple Page DocumentsYour fax machine can scan paper with a base weight between50 gsm and 105 gsm. You can load up to 20 sheets of standard80 gsm paper (e.g. photocopier paper) at the same time. If youuse a heavier paper, you can load up to 15 sheets. For very heavypaper, manually load sheets and send pages sheet-by-sheet.When loading several pages for transmission, paper thickness shouldbe between 0.08 mm and 0.13 mm. For single page transmission,paper thickness can be between 0.06 mm and 0.15 mm.Loading DocumentsTo prevent paper jams and problems during scanning, neatlystack your documents, aligning their edges, before loading. Donot load documents of different sizes at the same time.Note: You can load and prepare to transmit a documentwhile your fax machine is still sending or receiving anothermessage (as long as the document feeder is clear). To dothis, load the document, select your location and press theSTART key. Your document will be scanned into memoryand sent when the current communication ends.
