Epson WorkForce AL-M400DN User Manual page 72

Allocates additional printer memory for printing data, as opposed to receiving it. You may need to
turn this setting on if you are printing a very complex page. If a Print Overrun error message appears
on the LCD panel during printing, turn this setting on and reprint your data. This reduces the amount
of memory reserved for processing data so your computer may take longer to send the print job, but it
will allow you to print complex jobs. Page Protect usually works best when Auto is selected. You
will need to increase your printer's memory if memory errors continue to occur.
Note:
Changing the Page Protect setting reconfigures the printer's memory, which causes any downloaded
fonts to be deleted.
A4/LT Auto Switching
When A4 or Letter size paper is selected for printing and there is no paper source set to the selected
paper size, the printout is output in an alternate paper size (Letter for A4, or A4 for Letter).
Extended Mode
If On is selected, printing continues even after the Replace Toner Cartridge error message
appears on the LCD panel. However, the printing quality is not guaranteed, and the service life of the
photoconductor unit may be affected. When a new toner cartridge is installed, the setting
automatically returns to Off.
LCD Contrast
Adjusts the contrast of the LCD panel. Use the u Up and d Down buttons to set the contrast between
0 (lowest contrast) and 15 (highest contrast.)
LCD Backlight (For AL-M400 Series only)
If Auto is selected, the LCD backlight lights. Also, it turns off during Sleep or Deep Sleep mode. If Off
is selected, the LCD backlight is always off.
RAM Disk
Specifies the RAM disk size available for the Reserve Job function. See the table below for details.
