contrast of documents that you are sending.

change resolution

Resolution affects the transmission speed and quality of faxed documents. The

HP Fax only sends faxes at the highest resolution supported by the receiving fax.

You can change the resolution between pages only when receiving faxes. Follow

these steps to change the resolution:
1

Press Resolution.
Tip — You can also press Fax to access the Resolution setting.

Press to scroll through the following resolution settings:
– Fine: This is the default setting. It provides high-quality text suitable for

faxing most documents.

– Very Fine: Use this setting when you are faxing documents with very

fine detail. Very Fine only works if the receiving fax machine also has

the Very Fine setting. If you choose this option, be aware that the

faxing process takes longer to complete.

– Photo: This setting provides the best quality fax when sending

photographs. If you choose Photo, be aware that the faxing process

takes longer to complete. When faxing photographs, we recommend

that you choose Photo.

– Standard: This setting provides the fastest possible transmission with the

lowest quality of fax.

Note: Very Fine mode is not used when sending documents that are

scanned into memory, such as when you are broadcasting to multiple

recipients or scheduling a fax for later. If you are sending documents using

one of these methods, Very Fine will be changed to Fine even if Very Fine

was selected.

When the resolution setting you want appears, press Enter.

change contrast

Change this setting if you want a black-and-white fax to be darker or lighter than

the original. Follow these steps to change contrast:
1

Press Fax until Lighter/Darker appears.
The range of Lighter/Darker values appears as a circle on a scale on the

front-panel display.

Press to lighten the fax or to darken it. The circle moves to the left or

right, depending on the button you press. Press Enter to select the setting.
Note: The Lighter/Darker settings reset to the default two minutes after the

fax job is complete. You can change the default setting, see set new defaults

on page 20.
