1.6 Handling Precautions

1.6.1 Caution when there is a Power Failure

AcuLaser C1900 / AcuLaser C900 is equipped internally with nonvolatile memory
(E2PROM). This nonvolatile memory preserves the settings for printer functions, and
if the power is cut during writing to the nonvolatile memory, the contents of the
nonvolatile memory can not be guaranteed, with the result that when the power is
turned on again, or when Reset All is executed, the panel setting values will return to
the default settings, or a Service call error will occur.
With AcuLaser C1900, HDD can also be connected to this printer, but if the power is
cut during writing to the HDD, the writing contents can not be guaranteed, so a HDD
error may occur. Accordingly, in the following cases, the power to AcuLaser C1900
should not be cut while writing to the nonvolatile memory or to the HDD.
From the time the power is turned on until the On Line LED lights up
continuously.
While the Ready LED is blinking.
While the printer is printing (while the paper feed motor is operating).
While the Data LED lights up, or when it is blinking.

1.6.2 Caution Regarding High Temperature Parts

Take care not to touch the Fuser unit while the printer, is being opened to remove a
paper jam, etc., since the temperature of the Fuser unit inside the printer becomes high.
