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 6-1 for instructions.
•
Align the print head. See page 6-4 for instructions.
•
When you send a print job, make sure your print options are set
correctly. For more information, see Chapter 3 (Macintosh) or 4
(Windows).
