Resolving Problems
Using Hex Dump Mode
You can use the printer’s hex dump mode to identify problems if you know 
how to interpret hex code. Or, you can fax the hex printout to a technical 
support representative.
Make sure the printer has paper loaded and is turned off. Then follow these 
steps: 
1. Press and hold the 
Pause
 button while you press the 
Power
 button to 
turn on the printer. 
HEX DUMP=PRINT
 appears on the display.
2. Press the 
Enter
 button. 
3. Send your problem file to the printer.
The data in the print buffer is printed with 16-byte hex data in the left 
column and corresponding ASCII characters in the right column. If the 
last data is less than 16 bytes, you need to press the 
Pause
 button to 
print it. 
4. After you’re finished using hex dump mode, press the 
Power
 button to 
turn the printer off and exit maintenance mode.
Improving Print Quality
You can often improve print quality by doing the following:
Run a nozzle check and cleaning cycle. See page 3-1 for instructions.
Align the print head. See page 3-3 for instructions.
When you send a print job, make sure your print options are set 
correctly. For more information, see the RIP Station 5100 User Guide (if 
you have the RIP) or Appendix B or C (if you’re using the EPSON 
printer driver).
If none of these suggestions help, try the solutions on the following page.
