1.2.7 Media Take-up Unit
0014-8824
Media take-up unit
The Media Take-up unit spools the 2 or 3 inch core, the roll media (17" to 44"), after it is printed by the host computer.
Take-up begins once the falling paper is detected by the Media take-up paper detection sensor, attached to the weight roller.
The roll media may also be manually spooled, using the button on the media take up unit.
The media take-up unit has an overload protection feature to prevent accidents while spooling rolls. (This feature will disable the motor automatically when an
overload occurs while spooling a roll.)
Additional features of the media take-up unit include:
- An adapter may be installed to support a 3-inch paper tube.
- Roll media can be unwound by feeding them backwards to visually check the images.
- Weight rollers varying in length to suit specific roll widths ensure added takeup efficiency.
- The printer detects errors in the media take-up unit as an independent function.
- Linked with the printer's sleep mode.
