Check the error correction setting Usually, the product monitors the signals on the telephone line while it is sending or receiving a fax. If the product detects an error during the transmission and the error-correction setting is On, the product can request that the portion of the fax be resent. The factory-set default for error correction is On. You should turn off error correction only if you are having trouble sending or receiving a fax, and you are willing to accept the errors in the transmission. Turning off the setting might be useful when you are trying to send a fax overseas or receive one from overseas, or if you are using a satellite telephone connection. 1. From the Home screen on the product control panel, touch the Setup button. 2. Touch the Service menu. 3. Touch the Fax Service menu. 4. Touch the Error Correction button, and then touch the On button. Send to a different fax machine Send the fax job to a different fax machine to see if another machine will successfully receive the fax job. Clean the pickup rollers and separation pad in the document feeder If the product document feeder experiences paper-handling problems, such as jams or multiple-page feeds, clean the document-feeder rollers and separation pad. 1. Open the document-feeder cover. ENWW Improve fax quality 195
