Guide device for guiding a printed medium onto a take-up roll in a printing system

A method for guiding print a medium onto a take-up roll in a printing system, the method comprising the steps:

• sensing a lateral position of the medium on a transport path of the printing system for generating lateral position data;
• a controller receiving the lateral position data and determining from the lateral position data a position of a first guide member, the first guide member comprising a contact surface for contacting a side edge of a printed medium output from the printing system as the medium moves along the transport path towards a take-up roll for winding up a length of the medium;
• and
• setting the first guide member to the determined position to prevent lateral deviation of the medium along the transport path.

A method for detecting skew of a web medium, the method comprising the steps:

• a sensor sensing a first lateral position of the medium on the transport path;
• transporting the medium from the sensor along a contact surface of a first guide member positioned along the transport path to prevent lateral deviation of the medium, the first guide member comprising a contact surface for contacting a side edge of a printed medium output from the printing system as the medium moves along the transport path towards a take-up roll for winding up a length of the medium;
• determining a second lateral position of the medium from a position of a first guide member;
• and
• comparing the first lateral position and the second lateral position to determine skewing of the medium.
