Media Damper Cleaning
The media damper and its width guides can accumulate parts of labels,
adhesive and paper dust residue that can prevent the proper guiding of
labels.
• Cleaning Agent - Use an isopropyl alcohol wipe or isopropyl alcohol on a
clean cloth.
• Schedule - Clean the media damper and its width guides each time you
clean the printhead.
6. Clean the media damper by rotating it counterclockwise and remove any
label parts from its bottom surface. Then use an isopropyl alcohol wipe or
clean cloth moistened with isopropyl alcohol to remove all remaining
debris and adhesive from the damper and its inboard and outboard
guides.
IMPORTANT All adhesive must be completely removed to prevent future die cut
labels from being accidently peeled away from their liner.
Cutter Option Cleaning
The cutter requires only periodic cleaning.
WARNING Keep your fingers away from the cutter blade. It is sharp.
Perform the following procedure whenever too much dust or debris is visible.
1. Set the printer power switch to O (Off).
2. Rotate the deck lock lever fully counterclockwise until the pivoting deck
swings upward.
3. Open the cutter cover by sliding the cutter cover release lever to the right.
4. Use a cloth with a light amount of WD-40 oil to clean adhesive from the
cutter guides. Adhesive oil must be cleaned from the guides with a dry
cloth to prevent dust attraction.
5. Loosen the thumbscrew on the right side of the front panel and swing it
open.
6. Use a vacuum or can of compressed air with a nozzle around the area of
the cutter blade to remove any dust or debris.
7. Use a cloth with a light amount of WD-40 oil to clean adhesive from the
cutter blade. Adhesive oil must be cleaned from the blade and guides with
a dry cloth to prevent dust attraction.
CAUTION Do not use isopropyl alcohol to clean the cutter blade – it dissolves oils
required for lubrication.
8. Close the front panel and tighten the screw.
9. Properly route the media through the printer and cutter.
10. Close the cutter cover.
11. Close the pivoting deck by rotating the deck lock lever fully clockwise.
