About 3 weeks ago my fax here using LexMark X7170 will not fax to another number up at the business office up the street. I can successfully fax to any other fax number/fax but the sister office up the street. What I get is the message that it will resend in 3 mins and goes through trying to Re-Fax the document, but it never goes. The receiving Fax is fine, nothing modified. Is there an updated driver I should be loading? Any suggestions would be greatly welcomed. Thanks. Jim Kerrigan
