Sending of documents is too slow.
Is the resolution set to <FINE>, <PHOTO>, <SUPER
FINE>, or <ULTRA FINE>?
Setting the resolution to <STANDARD> reduces the
sending time.
Is Error Correction Mode (ECM) set to <ON>?
Because ECM corrects errors during a transmission,
any problems on the line can mean that the
transmission will take extra time. Set <ECM TX> to
<OFF>. (See “TX/RX SETTINGS,” on p. 11-11.)
Cannot send using Error Correction Mode (ECM).
Does the recipient’s machine support ECM?
If the recipient’s machine does not support ECM,
the document is sent in normal mode without error
checking.
