Hi,

283 and 232 communication errors are usually caused by excessive line noise.  Sometimes a retry will transmit the fax successfully.  Try turning off ECM and V.34 to V.14 from the Control Panel of the CLJ 2840.  This will turn off the Error Correction Mode (ECM) and also slow the modem speed down.  Toggling these settings will sometimes allow faxes to transmit properly if comm errors are seen. 

 Since comm errors are legitimate transmission errors- turning off ECM will allow faxes to transmit- but the data on the received or sent printed fax may not be as good a quality as a fax sent or received with ECM turned on.  From the Control Panel on the CLJ2840 print out a Menu Map to find these two Settings for ECM and V.34.  Try toggling ECM to OFF and turn V.34 to the V.17.
