Check the one-touch or coded speed dialing button and be sure it is registered correctly.

Call the other party and ask them to make sure paper is installed.

Allow time for the current document to finish sending.

Make sure there is a dial tone when you lift the telephone. If not, contact the local telephone company.

Make sure the receiving fax machine is compatible with the MultiPASS (which is a G3 fax machine).

Check the MultiPASS by making a copy. If the copy is clear, the problem may be in the receiving fax machine.

Remove the document and feed it correctly into the ADF. See page 1-13.

Cannot send or receive using Error Correction Mode (ECM)

The other party’s fax may not support ECM.

Some fax units do not support ECM transmission. If the other party’s fax does not support ECM trans- mission, then the document is sent in the normal mode without error checking.

Lower the transmission speed. See the Advanced: Send Fax dialog box (page 8-5) and the Advanced: Receive Fax dialog box (page 8-9).

The sending fax machine usually determines the fax’s quality. Call the sender and have them make sure the top cover and scanning glass on their fax machine are clean.
