Solution
Make sure the paper in the
sheet feeder meets the
specifications given in Appendix
A.
Make a copy with your
FAX-L250. If the copy looks
alright, then your FAX-L250 is
operating properly. Contact the
sender and have them check their
fax machine.
If the sending fax does not
support ECM, then the FAX-L250
receives the fax in normal mode
without error checking.
Make sure the FAX-L250 has its
ECM RX setting turned on.
Make sure the toner cartridge is
installed correctly. See page 2-27.
