The media supply hub package can be dismantled by removing the #T20
Torx screw at the end of the shaft. Inside the outermost hub module, there
is a spring that presses the hub package towards a felt pad in order to break
the rotation. Else, the momentum of a large and heavy media roll might
cause excessive media to be unwound when the printing is stopped. The
brake torque should be 70 ±20 Nmm (see Appendix C).
The rotation of the code disc fi tted at the innermost part of the hub pack-
age is detected by the paper sensor.
Be careful to fi t the studs of the innermost hub module into the holes in
the code disc when the package is assembled.
