Troubleshoot substrate If the problem remains after removing the substrate jam, unload the take-up reel from the front panel and load it again. Take-up reel does not wind Predictably, if the take-up reel is not winding as anticipated, the printed output is likely to end up on the floor. If the printer recognizes a problem with the take-up reel, it interrupts the print job until the issue is corrected. If the printer does not recognize a problem, the job continues to print. The following table highlights possible issues and solutions. Take-up reel LED status Blinking quickly Issue Take-up reel is not winding Print job interrupted? Yes Blinking slowly Solid red Take-up reel is not No winding Take-up reel is not No winding Solid green Solid green Take-up reel is not No winding Take-up reel is winding No in the wrong direction Possible cause Possible solution The sensor beam was blocked for more than 3 seconds. Make sure that the take-up reel sensors are not blocked by a strip of substrate or any objects. See the following graphic. Make sure that the collection bin is placed behind the foot brace. Also ensure that the take-up reel power switch is in the On position. The sensor cables are loose or unplugged. Ensure that the sensor cables are correctly secured. There is too much resistance on the takeup reel motor. Ensure that the substrate is not winding too tightly. A loopshaping core should be inserted and hanging as shown in the User's guide. The take-up reel power switch is in the Off position Ensure that the take-up reel power switch is in the On position. The take-up reel winddirection switch is in the wrong winding position. Flip the take-up reel wind-direction switch to the correct position. After 3 seconds, the printer recognizes the problem and interrupts the print job. See the first error listed in this table. The following graphic shows the take-up reel sensors and cable. 70 Chapter 7 Troubleshoot substrate issues ENWW
