• Code: 30.00.01
• Display: 30.00.01
• Description: Scanner communication error. The formatter is unable to communicate with the scanner.
• Remedy: 1. Reseat the 256 MB memory DIMM on the back side of the formatter. 2. Reseat the flat cable from the formatter to connector CN101 on the scanner controller PCB. 3. Replace the 256 MB memory DIMM on the back side of the formatter. 4. Replace the flat cable from the formatter to connector CN101 on the scanner controller PCB. 5. Replace the formatter. 6.

• Code: 30.01.01
• Display: 30.01.01
• Description: The flatbed scanner cover is open. This is a status message only.
• Remedy: 1. Ensure the flatbed cover is closed. 2. If the message persists, check that the scanner-open sensor at the left-rear of the scanner moves up and down correctly. If not, replace the scanneropen- sensor holder assembly. 3. Replace the scanner-open sensor.

• Code: 30.01.02
• Display: 30.01.02
• Description: A paper jam has occurred in the ADF paper path.
• Remedy: 1. Open the scanner jam-release cover and check all areas for jammed paper or labels that might be blocking a sensor. 2. Check that the mylar strip and holder are installed correctly. 3. Use the ADF sensor tests to ensure the ADF paper-present and ADF topof- page sensor flags move freely and the sensors are working properly. 4. If the jams persist, reseat the ADF pickup roller assembly. 5. Replace the ADF assembly.

• Code: 30.01.03
• Display: 30.01.03
• Description: The ADF could not pick up the paper. If the paper does not pass the paper-presence sensor, it will be reported as an ADF paperpick error.
• Remedy: 1. Check that the ADF jam-access door is fully seated. 2. Check the movement of the ADF driver gear on the ADF jam-access door to make sure it engages with the ADF input motor. A grinding noise can sometimes be heard when the paper is initially picked; this indicates the gear is not fully seated against the motor. In this case, replace the ADF pickup gear.
