In the Print T30 Reports field, you can set the frequency with which T30 reports are printed. T30 reports are detailed reports about the fax communication that occurs during the most recent fax transaction. The reports are useful when diagnosing failed fax sessions and may be requested by a service technician should a support call be necessary. The report will be printed at the MFP either on request or in accordance with the setting you choose.

In the Signal Strength field, you can adjust the fax signal strength used to communicate on the phone line.

CAUTION The Signal Strength setting should not be adjusted unless you are advised to do so by a qualified service technician in order to correct malfunctioning fax communications.
