1.10 Notes on Operation

1.10.1 Powering Off (EPL-5900)

EPL-5900 incorporates an internal non-volatile memory (EEPROM).
If the printer is powered off during the process of writing in non-volatile memory, the
writing operation to the non-volatile memory cannot be guaranteed. And therefore the
next time the printer is powered on or the "Reset All" is carried out, panel settings may
be initialized or a service call error may occur.
The non-volatile memory saves the function settings, and the following cases are those
in which the memory is rewritten, and therefore the printer should not be powered off:
After the printer is powered on, until the Ready LED lights up.
While the printer is printing.
(While the paper feed motor is operating.)
While the Data LED is flashing or lit.
To stop the printer, either put it off line or carry out All Print Data Cancel.

1.10.2 Caution About Hot Parts (EPL-5900/EPL-5900L)

The fuser unit inside the printer is heated to high temperatures, once the printer cover is
opened to clear paper jam or for some reasons, take care not to touch the fuser unit.
Product Description
1.10.3 About the Moist Environment Mode Select Jumper
(EPL-5900L)
Jumper switch "JP9" on the controller board is a jumper for selecting the moist
environment mode.
This is a switch to be operated to lower the print density in a high humidity
environment. Ordinarily it should not be operated.
Use this switch only in cases where the above special environmental conditions exist.
When the environment of use returns to normal environmental conditions, it is
necessary to return it to the original setting immediately. The following jumper setting
1-2 is excluded from the print quality guarantee in the normal environment.
If the user environment is special and it is difficult to handle environmental conditions
by any other method, this setting can be set by a service technician. This jumper is not
disclosed to the public and is not accessible to users.
Setting:
1-2 Set if the printer is used in a high humidity environment.
2-3 Set when the printer is used in a normal humidity environment (factory
default setting).
