The Image Quality of Received Faxes is Poor

The following causes can be considered.

ECM setting is disabled.

Solutions

Select Settings > Fax Settings > Basic Settings and enable the ECM setting on the printer's control panel. This may clear errors that occur due to connection problems. Note that the speed of sending and receiving faxes may be slower than when ECM is disabled.

The image quality setting is low on the sender's fax machine.

Solutions

Ask the sender to send faxes at a higher quality.
