EPSON EPL-5900/EPL-5900L

1.6 RAM Expansion

<EPL-5900>
When EPL-5900 runs out of memory, the Memory LED flashes or lights up.
NOTE: This indication corresponds to "Mem Overflow" or "Image Optimum"
or "Need Memory" or "Collate was disabled" displayed on the LCD of
an LCD-mounted model.
This problem may be solved by taking appropriate ones of the following measures:
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 (only for EPSON) SDRAM DIMMs for PCs: 90pins, 32-bit

Product Description
<EPL-5900L>
If a problem with insufficient memory occurs in EPL-5900L, an underrun error is
displayed on the host computer's screen. In this case, it is necessary to install additional
memory.
Depending on use conditions, the recommended RAM capacity is as shown below.
However, there are some cases where an underrun error is displayed even when
memory has been expanded if an image of an extremely low compression ratio is
handled. In such cases, not only should the memory be expanded, but the resolution
should be reduced to 300 dpi, EnhancedMicroGray should not be used or other
appropriate changes made in the settings.
