This usually occurs during a manual transmission or when an incorrect number was dialed. Call someone at the remote machine. T.1.4 The STOP button was pressed during transmission. T.2.1 CFR or FTT was not received from the remote machine. Either the phone line disconnected during fax communication or transmission became impossible due to bad phone line conditions. Try the call again. It may be necessary to increase the output levels on machine parameter A1. The receive machine may also have closed network or block junk fax enabled. T.2.2 The two fax machines were incompatible. No mailbox at receiver or security tx is enabled. T.2.3 FTT was received from the remote machine at 2400bps. Bad phone line conditions made fax communication impossible. Conditions can change rapidly, so try the call later. Turn on the echo protect tone on Memory Switch B0. Also adjust the interval between DCS and TCF on Memory Switch B1. If the problem persists, try increasing the output levels on machine parameter A1. T.3.1 Document feed error, maximum document length exceeded, or insufficient lamp brightness. T.4.1 No response to MPS/EOP/EOM. Poor phone lines caused the receiving unit to disconnect. Adjust the interval between CFR and data on Memory Switch B1. Try increasing the output levels on Machine Parameter A1. It may also be necessary to adjust the transmit speed on Memory Switch B0. T.4.2 RTN was received from the remote machine. After transmission began, poor line conditions developed. Try the call again. Attempt the solutions described for the T.4.1 error. T.4.4 Poor line conditions prevented transmission. PIP was received. The transmission was interrupted by the call mode. The receiving unit may be experiencing problems. Try the call again. T.5.1 No response to RR from the remote machine. Line noise or other problems prevented ECM transmission. Increase the ECM response time on Memory Switch B2. T.5.2 No response to CTC. Line noise or other problems prevented ECM transmission. Increase the ECM response time on Memory Switch B2. T.5.3 EOR was received from the remote unit but further transmission was not possible.
