Cleaning The Print Head, Platen And Rollers; Cleaning The Print Head With Cleaning Sheet - SATO LC400e Series Operator's Manual

Section 4: Cleaning and Maintenance

4.1 CLEANING THE PRINT HEAD, PLATEN AND ROLLERS

The print head not only generates printouts of barcodes, but also graphics and text. To produce optimal
printing, it must be kept clean despite the dirt and adhesive that constantly accumulates on its print surface.
Furthermore, dirt can accumulate along the label path, affecting parts like sensors and guides, and reducing
their performance.
Therefore, it is important to clean these important components periodically. The printer cleaning kit and
cleaning sheets can be purchased from your authorized SATO representative.
When to clean with the cleaning sheet

For print head: clean after using every six rolls of media, or when you find any burned glaze on the surface
of the print head.

4.2 CLEANING THE PRINT HEAD WITH CLEANING SHEET

If certain stains on the print head cannot be removed easily with cotton swabs dabbed in cleaning solution, the
cleaning sheet is used for clearing such stubborn debris on the print head.
1. Make sure the printer is powered off and remove the
power cord.
2. Lift up the top cover.
3. Release the print head lock lever by turning counter-
clockwise.
The print head is now accessible.
4. Remove the media and the ribbon.
5. Put the head cleaning sheet between the print head
and the platen roller. The coarse side of the cleaning
sheet should face the surface of the print head
elements.
6. Now remount the print head by turning the head lock
lever clockwise until it latch on. The print head should
lock into place firmly.
7. Using both hands, pull the cleaning sheet outwards,
toward your body. This will remove any dirt stuck to the
print head.
8. When the cleaning sheet has been removed, perform
steps 5 to 7 to repeat the cleaning procedure one or two
more times.
9. When no more additional dirt appears on the cleaning
sheet after it has been pulled out, you can stop cleaning
with the sheet.
