the print head time to cool.

Ribbon Cassette

the counter spring In the ribbon cassette hole with the tip
of a ballpoint pen or other object Once the ribbon
cassette is mounted onto the carnage and printing Is
performed for a short time, the characters become
darker.

the ribbon has too much ink, the characters may
smear when printed.

such case the printer needs servicing.
