5. Maintenance
5.1 Clean and Maintenance
To ensure the normal operation of FC53-Li/FC53-Lc/FC53-Ri/FC53-Rc, the entire unit should be
cleaned regularly.
Special attention should be paid to the inside of the printer body, especially if food residues
are able to fall into the printer unit.
Turn off the power to the controller.
Turn off and isolate the air supply to the printer body.
Remove the printer ribbon cassette and clean inside the printer body. Since there are
multiple electronic components in this device, do not use the water to clean the unit. Use
isopropanol cleaning wipes for this purpose.
In order to clean the residue inside the printer body, it is recommended to use a soft-
bristled brush for cleaning.
5.2 Maintenance Plan
5.2.1 Quick/Regular Checks
Check and clean the print head (daily check). Use isopropanol wipes to clean.
Check if the ribbon passes the ribbon cassette correctly. Pull the ribbon through by hand,
visually check to see if the ribbon is wrinkling across the entire ribbon width.
Check for any ink on the peel roller and use isopropanol wipes to clean it when necessary.
Check if the “Darkness/Speed” setting meets the site standards. This will ensure excellent
print quality, but it may also highlight any potential problems. For example, if the darkness
is unusually high, the print head may need cleaning. The darkness has probably been set
high to compensate.
Check that the air pressure is set to the recommended pressure.
Check the condition of the platen rubber (FC53-Lc/FC53-Rc continuous printer) / rubber
(FC53-Li/FC53-Ri intermittent printer). Clean or replace it if necessary. The platen rubber
needs to be smooth, flat and free of debris. To replace the platen rubber, first remove the
old platen roller. Remove any adhesive from the metal platen base. For best results,
replace with FC53 platen rubber.
