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
You can select this option if you want to print documents in the Desktop Manager using a
reduced amount of ink, thereby saving printer ink. When using this option, the printed
document may appear to be less bright or contrasted.
Listen Time Before Ringing
When a call is received, the MultiPASS checks to see if the call is from a fax machine or a
telephone. If the MultiPASS does not have enough time to detect the fax tone, it assumes
the call is from a telephone. You use this option to set the appropriate amount of time to
allow the MultiPASS to check for the type of call.
