W1110, 1E40, 1E35, 1E41, or 1E45 label printer feeds incorrect label size when printing a label in SendPro Online

Products affected: SendPro® Online, W1110 (1E40, 1E35, 1E41, 1E45) label printer


When printing a shipping label in SendPro Online, a W1110, 1E40, 1E35, 1E41, or 1E45 printer feeds more than one label's worth of paper.


The printer may need to be recalibrated.


  1. Reboot the printer:
    1. Turn the printer off.
    2. Wait 1 minute.
    3. Turn the printer back on.
  2. If the issue is not resolved, perform a media calibration:
    1. Open the printer’s top cover and feed the label so that it is ¼ inch out of the printer.
    2. Press and hold the Stop/Resume and the Feed/Cancel buttons simultaneously just until the rollers begin to move the labels. Immediately release both buttons when the label roll begins to move. The roll should advance one label and the left LED should be solid green.
