Telescoping or damaged side edges in loose winding

Introduction

Solve issues of telescoping media or damaged side edges by adjusting the winder settings for loose winding. This is only applicable when you print with the settings [No tension bar] or [Locked tension bar].

Damaged side edges

Telescoping media

Air between media layers

Before you begin

If telescoping and/or damaged side edges occur while using loose winding, first do the following:

  • Set the winding strategy for the media to [0] in the RIP.

  • Set the side guides tight to the media, less than 1 mm (0.04 inch).

  • Gently push the media guides to check if they move. If the side guides can be moved easily, they must be replaced. You can temporarily secure them with tape until they are replaced.

  • Make sure the media has a straight cut leading edge feeding into the machine.

  • Make sure that the media is fed straight into the machine from the input side.

  • Make sure that the input roll in the drawer is not telescoped and that the side edges are not damaged.

  • Make sure that the media is taped correctly to an empty take-up roll core. See Print and wind without a tension bar or Print and wind with a locked tension bar.

Procedure

  1. In the settings editor, enable the setting [Increased winder slack].

    This setting takes effect immediately. You do not need to pause the job.

  2. Wind the media at least 15 m (49 ft) to check the winding quality.
    • If damage to side edges continues to occur, call your local service representative.

    • If no side edge damage, and no telescoping occurs, no further action is required.

    • If telescoping continues to occur, follow the next steps of the procedure.

  3. If air between media layers occurs, go to [Media manager]  → [Select material]  → [Edit]  → [Basic media profile settings]  → [Media options]  → [Winding strategy] to increase the winding strategy with 1 step at a time, up to a maximum of 5 in total.
    NOTE

    This procedure shows the steps in ONYX.

    Heavier media benefit the most from this setting. Winding strategy alterations are only visible to jobs that you send and tape after you change this setting.

  4. If telescoping still occurs, without air between media layers, call your local service representative.
