4.5) Install the printer ribbon
Remove the lid, then:
1 Rotate the media guide completely downwards.
2 Extract both feed (rear) and take up (front) spindles by carefully pulling them upwards.
3 Fit the printer ribbon on to the feed spindle (rear), locating the slot in the ribbon spool fully on to the key on the spindle.
When viewed from the front of MG3, the key should be on the right hand side with the lead of the ribbon underneath, facing
forward.
4 Relocate the loaded feed spindle firmly into its seatings in MG3. Unroll sufficient ribbon to pass under the rear guide bar under
the sensor card and over the template.
5 Continue unrolling the ribbon until it has passed under the front lower guide bar and is protruding through the carriage
aperture.
6 Fit the ribbon take up spool provided with MG3 onto the take up spindle (front), locating the slot in the spool fully on to the
key on the spindle.
7 Using the carriage/template as a convenient base, position the take up spool at the end of the protruding printer ribbon such
that the white cog is on the left hand side (viewed from the front). Ensure the ribbon is square to the spool and attach the
end of it to the spool with adhesive tape.
• Carefully and accurately wind a few turns of ribbon around the spool.
8 While carefully pulling ribbon through MG3, relocate the loaded take up spindle into its seatings in MG3. Ensure the ribbon
is correctly aligned on the front guide bars, without, tears, folds or creases.
9 IMPORTANT: Rotate the media guide completely upwards, then replace the lid.
Do not operate MG3 without the lid in place.
• We recommend cleaning the print head at each ribbon replacement, using only the genuine CEMBRE MG2-CKP 991670
