If the toggles are not positioned correctly or adjusted to apply the correct pressure, you may see issues while printing. Use these steps to adjust the toggle pressure.
Open the printhead assembly by rotating the printhead-open lever to lessen the pressure on the toggles.
Loosen the locking nut at the top of the toggle you want to move.
Reposition the toggle as necessary to provide even pressure on the media. For extremely narrow media, position the inside toggle over the center of the media, and decrease the pressure on the outside toggle.
