1.7 Handling Precautions
1.7.1 Caution when there is a Power Failure
This printer is equipped internally with nonvolatile memory (E
2
PROM).
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 cannot be guaranteed, with the result that
when the power is turned on again, or when a Reset All is executed, the
panel setting values will return to the default settings, or a Service Call
Error will occur.
A HDD can also be connected to this printer, but if the power is cut during
writing to the HDD, the writing contents cannot be guaranteed, so a HDD
error may occur.
Accordingly, in the following cases, the power should not be cut while
writing to the nonvolatile memory or to the HDD.
1. From the time the power is turned on until the On Line LED lights up
continuously.
2. While the On Line LED is blinking.
3. While the printer is printing (while the paper feed motor is operating).
4. When stopping printing, either it should be made Off-line or the
printer should be reset.
5. While the Data LED is lighted up, or when it is blinking.
1.7.2 Caution Regarding High Temperature Parts
The temperature of the Fuser Unit inside the printer becomes high, so if
you are opening the printer to remove a paper jam, etc., care should be
taken not to touch the Fuser Unit.
