Data Dump Mode; Optimizing Print Quality; Adjusting The Ritech Setting - Epson EPL-5000 Guide De L'utilisateur

Data Dump Mode

The data dump mode is a special feature that makes it easy
for experienced users to find the cause of problems in
communications between the printer and computer. In the data dump
mode, the printer produces an exact printout of the codes it receives.
1. Make sure that A4 paper is loaded and the printer is off.
2. Hold down the Level 2 button while you turn on the printer. Make
sure you hold down the button until the message READY: X
DUMP appears on the display. X indicates the channel being used.
3. Run any program that causes the printer to print. The printer prints
out all of the codes it receives in hexadecimal format.
4. To turn off the data dump mode, turn off the printer or press
the Reset button until INITIALIZE appears on the display.

Optimizing Print Quality

Adjusting the RITech setting

Resolution Improvement Technology (RITech) is EPSON's printer
technology that produces smoother and crisper lines, text, and
graphics.
RITech has four settings: LIGHT, MEDIUM (default), DARK, and
OFF. The default setting produces the best text and graphics in most
cases and should not normally have to be changed. However,
adjusting the RITech setting can sometimes improve print quality.
Note:
RITech may not improve graphics that include gray shading or a
screen pattern. If you are printing gray shading or screen patterns,
you might want to change the RITech setting to OFF.
