Expansion Ram; Powering Off - Epson EPL-5800 Service Manual

EPSON EPL-5800
1.8 Notes for Operation

1.8.1 Expansion RAM

When EPL-5800 runs out of memory, the Memory LED flashes or lights.
(Corresponds to "Mem Overflow", "Image Optimum", "Need Memory" or "Collate
was disabled"on the machines with LCD.)
In this case, any of the following measures may be taken;
"
Reducing the resolution.
"
Select "Halftone" when using Enhanced MicroGray.
"
Reducing the receiving buffer size to "Minimum".
"
Use only one interface and set "Off" for other interfaces.
The only way to definitely avoid memory shortages is to install more memory.
(Commercially available SDRAM DIMMs for PCs: 168 pins, 64-bit with SPD)

1.8.2 Powering Off

EPL-5800 includes an internal non-volatile memory (EEPROM).
If the printer is powered off during the process of writing to 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 OnLine LED lights.
"
While the printer is printing.
(While the paper feed motor is operating.)
"
While the Data LED is flashing or lights.
To stop the printer, either put it off line or carry out a Reset.
1.8.3 High-Temperature Components
The fuser unit inside the printer becomes hot, and therefore care must be taken not to
touch the fuser unit while opening the printer to clear a paper jam.
