Setting Up Advanced Receive Fax Options
To change the following Advanced Receive Send Fax options, click
Advanced on the Receive Fax tab. You see this dialog box:
Speed
You can set the transmission speed used to receive faxes. The higher the
setting, the faster the fax is received. If you experience problems when
receiving faxes, try a lower speed setting.
Error Correction (ECM)
You can select this option to reduce system and line errors when
receiving a fax. With this option selected, the system checks each
incoming fax for lost data. If data has been lost from a portion of a page,
the system receives that portion again after confirming that all data
within that portion can be received successfully.
Ink/Toner Saver Mode
You can select this option if you want to print documents in the
Desktop Manager using a reduced amount of ink, thereby saving ink.
When using this option, the printed document may appear to be less
bright or contrasted.
