Header Info

Reason for Change

The existing dampers become loose,as either the glue gets unglued
or the thin layer of the blue rubber comes off with the glue.
Typically the problem seems as patterns or lines on the film.

Description of Change

Replace the lead screw and the stepper motor dampers with the
supplied damper.

Change Procedure

Use the procedure below for the damper replacement.

1. Open the right and left side doors.
2. Loosen the two screws on the stepper motor damper and pull out the damper.
3. Loosen the two screws on the lead screw damper adaptor and pull out the damper together with the adaptor.
4. Install the new damper on the lead screw axis at the End Position side by tightening the two screws (no adaptor is needed).

Only one new damper replaces the two old ones.

Test Procedure

Move the carriage from Home Position to End Position and back, a few times and check if the new damper sits properly.
Expose a file and check for patterns.
