Ribbon wrinkle often appears as a diagonal void that occurs intermittently on printed labels. This issue can be resolved by one or a combination of the suggestions listed in this article.
Media
Wrinkle can be caused by an excess of ribbon on the ribbon take-up spool. Remove excess ribbon from the take up spool. Test printing to confirm any change in print quality. Confirm that the ribbon is winding smoothly around the plastic ribbon take-up spindle.
Make sure you are using a ribbon as close to the width of the of the labels and liner as possible. A significantly wider ribbon requires more precise plunger pressure positioning to avoid wrinkle.
Ensure the platen roller is not too narrow for your media.
Mechanical Printer Adjustments
Mechanical adjustments can be performed with the included hex wrench.
Note: Do not attempt to adjust print head pressure or alignment as a first troubleshooting step. Over-tightening can easily damage the print head. Once alignment has been modified it can be very difficult to revert to original settings in the event something goes wrong.
Adjust Pressure Plungers
Position the two red/black tension plungers evenly over the printhead - about 3/4" over the label on both the left and right sides so pressure is applied evenly across your labels. If the wrinkle moves from lower right to upper left, there is more tension on the right side than on the left. If the wrinkles move from lower left to upper right, there is more tension pressing down on the left side.
Adjust the Ribbon Deflection Bar
Adjust the transfer ribbon deflection by using the Allen screw on the left-side above the printhead. Turn the screw a half turn in one direction and press the Feed button on the front panel. (Clockwise increases pressure, Counter Clockwise decreases pressure) If the wrinkle is decreasing, move it a bit more in the same direction. If it got worse, turn the screw one full rotation in the opposite direction - (half to go back to where you started and another half to go in the needed direction).
