Is the cable damaged? Replace the paper path cable. See “Paper path cables”. Go to step 4. 4 Remove the staging deflector assembly, and check the sensor cable connection. See “Staging deflector assembly removal”. A—Input sensor B—S1 sensor C—Narrow media sensor D—Near narrow media sensor Is the cable properly connected? Go to step 5. Reseat the cable. 5 Replace the sensor. “Sensor (input, S1, narrow media, near narrow media) removal” Does the error reoccur? Replace the system board. See “System board removal”. Problem solved.

• Code: 200.02
• Description: Paper hit the input sensor too soon. Possible causes: • Damaged input sensor flag or input sensor • Loose input sensor
• Remedy: 1 Open the left access door. Check the input flag (A) for damage. Is the input flag damaged? Replace the input sensor. See “Sensor (input, S1, narrow media, near narrow media) removal”. Go to step 2. 2 Remove the staging deflector assembly. See “Staging deflector assembly removal”. Is the input sensor (A) in the staging deflector assembly loose? Reseat the sensor and add a sensor retainer. See “Sensor (input, S1, narrow media, near narrow media) removal”. Contact your next level of support.

• Code: 200.03, 200.08
• Description: Input sensor is never made or made late. Possible causes: • Faulty input sensor • Faulty staging deflector assembly • Faulty autocomp assembly
• Remedy: 1 Remove the input tray. Are the pick tires worn? Replace the pick tires. See “Pick rolls removal”. Go to step 2. 2 Open the left access door. Check the input sensor flag (A) for damage. Is the input sensor flag damaged? Replace the input sensor. See “Sensor (input, S1, narrow media, near narrow media) removal”. Go to step 3. 3 Is the staging deflector assembly damaged? Replace the staging deflector assembly. See “Staging deflector assembly removal”. Go to step 4. 4 Turn the printer off, and open the system board shield. Check the cable in connector JPP2 for proper connection to the system board. Is the cable properly connected? Go to step 5. Reseat the cable. 5 Check the cable in connector JPP2 for any other damage. Is the cable damaged? Replace the paper path cable. See “Paper path cables”. Go to step 6. 6 Remove the staging deflector assembly. See “Staging deflector assembly removal”. Is the cable connected correctly? Go to step 7. Reseat the cable. 7 Replace the input sensor. See “Sensor (input, S1, narrow media, near narrow media) removal”. Does the error reoccur? Replace the System Board. See “System board removal”. Problem solved

• Code: 200.04
• Description: Input sensor flag broke early. Possible cause: • Incorrect paper settings • Faulty input sensor • Faulty system board
• Remedy: 1 Open the left access door. Check the sensor flag for damage. A—Input sensor B—S1 sensor C—Narrow media sensor D—Near narrow media sensor Is the sensor flag damaged? Replace the input sensor. See “Sensor (input, S1, narrow media, near narrow media) removal”. Go to step 2. 2 Turn the printer off, and open the system board shield. Check the cable in connector JPP2 for proper connection to the system board. Is the cable properly connected? Go to step 3. Reseat the cable. 3 Check the cable in connector JPP2 for damage. Is the cable damaged? Replace the paper path cable. See “Paper path cables”. Go to step 4. 4 Remove the staging deflector assembly, and check the sensor cable connection. See “Staging deflector assembly removal”. A—Input sensor B—S1 sensor C—Narrow media sensor D—Near narrow media sensor Is the cable properly connected? Go to step 5. Reseat the cable. 5 Replace the sensor. “Sensor (input, S1, narrow media, near narrow media) removal” Does the error reoccur? Replace the system board. See “System board removal”. Problem solved.

• Code: 200.05, 200.07
• Description: Input sensor does not break or breaks late. Possible causes: • Incorrect paper settings • Incorrect paper loading • Incorrect paper guide setting • ITU module failure • Lower guide failure • Paper pick mechanism failure • Input sensor failure
• Remedy: 1 Reseat the ITU. Did the error clear? Problem solved. Go to step 2. 2 Open the left access door. Check the input sensor flag (A) for damage. Is the input sensor flag damaged?
