If this is not the case, then check the input trays to make sure that the media is centered and not closer to either front or back. 5 Make sure that the media is not touching the plastic arms (wings) in the accumulator. 6 Make sure that customers are not blocking the exit of the accumulator when waiting for their print jobs. 7 Check for interference at the exit of the accumulator. NOTE: Media with excessive curl can block the exit. 8 Make sure that the paper stopper clips are in their correct position. 9 Make sure that the accumulator exit roller cover is installed correctly. 10 Replace the accumulator as needed. 13.12.20 Jam in left accessory 13.12.14 13.12.14 13.12.20 Amber blinking Yellow (3 blinks) Media is present in the accumulator at power-on (the ACEXIT sensor is activated when the bearing bracket is closed).
