Failure
Possible Cause
Solutions
The paper
feeds slowly
and unevenly.
As the paper-feeding device has been
used for a long time, its transmission
ability is degraded by worn gear or loose
connector.
Tighten the transmission unit,
and apply some lubricating oil on
the gear and both ends of paper
shaft.
As the paper-feeding device has been
used for a long time, its transmission
resistance increases.
Contact our service department
for maintenance or replacement.
The recorder is deformed by external
force collision, thus affecting the paper
speed.
Contact our service department
for maintenance or replacement.
The paper is out of specification, thus
the resistance becomes over-large.
Select and use the specified
paper.
The paper has been installed for a long
time, it gets heated or moistened, which
makes local viscosity increase, thus
affecting the paper speed.
Replace the paper
ECG machine is not well cleaned and
maintained. The recorder’s transmission
unit is dusty, thus degrading the
transmission ability.
Inspect and clean the ECG
machine to remove moisture and
dust.
