Abstract

A liquid ejecting apparatus includes a scanner unit, a scanner drive section that drives the scanner unit, a head unit that is provided with an ejection section, a drive signal generation section that generates a drive signal driving the ejection section, a casing in which the head unit is disposed, a temperature information output section that outputs temperature information indicating a value corresponding to a temperature in the casing, and a stop control section that decides a time length of the stop period in which generation of the drive signal is stopped based on the temperature information, in which the time length is longer when the scanner unit is driven than when the scanner unit is not driven.

Claims9

Dependent claims

A liquid ejecting apparatus comprising:

a scanner unit that reads an image formed on a medium;
a scanner drive section that drives the scanner unit;
a head unit that is provided with an ejection section that ejects a liquid;
a drive signal generation section that generates a drive signal for driving the ejection section;
a casing in which the head unit is disposed;
a temperature information output section that outputs temperature information indicating a value corresponding to a temperature of a predetermined portion in the casing;
and
a stop control section that decides a time length of a stop period in which the drive signal generation section stops generating the drive signal based on the temperature information,
wherein the time length is longer when the scanner unit is driven than when the scanner unit is not driven.
