What can I do if the Cover Sensor isn't Working?

Before troubleshooting, make sure that you are not in Service Mode 1 because the Cover sensor is disabled and Printer will think that the cover is always closed. Power OFF the Printer and switch it back ON again and check if the Cover sensor works. Check if the cable for front4panel assembly is connected correctly to the electronics module. Replace the front4panel assembly.

What can I do if the Printer has problems with Media Loading?

Check that the Media Sensor is installed correctly. Check if the cable for Media Sensor is connected correctly. Check if the Pincharms are down (the Pincharm lever should be up). Make sure that the Line Sensor is installed correctly. If necessary, perform the Carriage Test. Perform the ￿ccuracy Calibration. Replace the Media Sensor (part of the overdrive assembly). Replace the Carriage ￿ssembly.

What can I do if the Bail Mechanism Fails?

Check that there are no obstructions in the way of the Bail ￿ssembly. The cam gear and engaging gear may not make correct contact with the left drive4roller gear even though the carriage is actuating the engaging lever. This can happen due to excessive wearing of parts. ￿nother problem may be that the bail cable has broken. The carriage may not properly locate the engagement lever, preventing the gears from engaging. ￿ny problems with the carriage4motor control system (for example, the encoder strip) or associated mechanics could cause this problem. ￿lso, if the carriage cannot find the true left stop during initialization (caused by interference), the engaging lever cannot be located. The bail may fall from the up position. This can happen if the cam is over or under4rotated. The notch on the cam, used to engage the left bail bracket, is not properly located for the •bail up" condition, and the bail falls abruptly. Perform a bail cycle test. If the carriage moves over the engaging lever without raising it, you may need to adjust the carriage angle on the slider rod. However, be careful not to jeopardize the print quality, which is very sensitive to the carriage angle.
