Guideline to Replace the Linerless Platen Roller (CL4NX Only)

The linerless platen roller has a blue striped marking
on the left side. When the blue striped marking started
to fade off, it indicates that you should replace the
linerless platen roller.
This is only a general guideline, the condition of the
platen roller wears out varies depending on the used
media. In any cases, replace the worn platen roller
when it affected the printing quality of the printer.
