Aligning Vertical Lines in Your Printout 
If you notice that the vertical lines in your printout are not 
properly aligned, you can use the printer’s bidirectional 
adjustment mode to correct this problem.
Note:
o
To complete the steps below, you need four sheets of A4 or letter size 
single-sheet paper or four pages of continuous paper that are at least 
279 mm (11 inches) long and 241 mm (9.5 inches) wide.
o
If you use single sheets without an optional cut-sheet feeder, you 
need to load a new sheet of paper each time the printer ejects a printed 
sheet onto the paper guide. 
Follow these steps to perform the bidirectional adjustment:
1. Make sure paper is loaded and the printer is turned off.
 
c
Caution:
Whenever you turn off the printer, wait at least five seconds 
before turning it back on; otherwise you may damage the 
printer.
2. While holding down the Pause
 button, turn on the printer. 
The printer enters the bidirectional adjustment mode and 
then prints instructions and the first set of alignment patterns.
3. As described in the instructions, compare the alignment 
patterns and select the pattern with the best alignment.
4. Follow the instructions to print the remaining sets of 
alignment patterns and select the pattern with the best 
alignment in each set.
5. After you select the best pattern in the final set of alignment 
patterns, turn off the printer and exit the bidirectional 
adjustment mode. Your selections are saved automatically.

Printing a Self Test 
Running the printer’s self test helps you determine whether the 
printer or the computer is causing the problem:
oIf the self test results are satisfactory, the printer is working 
properly and the problem probably results from your printer 
driver settings, application settings, computer, or interface 
cable. (Be sure to use a shielded interface cable.)
oIf the self test does not print properly, there is a problem with 
the printer. See “Problems and Solutions” for possible causes 
and solutions to the problem.
You can print a self test using either single sheets or continuous 
paper.
Note:
Self test prints characters on the full width of the printable area. Use 
paper that is at least 297 mm (11.6 inches) wide, such as an A3-size sheet.
To perform a self test, follow these steps:
1. Make sure paper is loaded and the printer is turned off.
 
c
Caution:
Whenever you turn off the printer, wait at least five seconds 
before turning it back on; otherwise you may damage the 
printer.

2. To run the test using the Draft font, hold down the LF/FF
 
button while you turn on the printer. To run the test using the 
printer’s letter-quality fonts, hold down the Load/Eject
 
button while you turn on the printer.
After a few seconds, the printer loads the paper automatically 
and begins printing a self test. A series of characters is printed.
3. To end the self test, press the Pause
 button to stop printing. 
Then eject or tear off the printed page(s) and turn off the 
printer.
Printing a Hex Dump 
If you are an experienced user or a programmer, you can print a 
hexadecimal dump to isolate communication problems between 
the printer and your software program. In hex dump mode, the 
printer prints all data received from the computer as hexadecimal 
values.
You can print a hex dump using either single sheets or continuous 
paper.
Note:
Use continuous paper that is at least 241 mm (9.5 inches) wide or A4 or 
letter size single-sheet paper.

4. To turn off hex dump mode, press the Pause
 button to stop 
printing. Then eject or tear off the printed page(s) and turn off 
the printer.

Cut-Sheet Feeders
Two cut-sheet feeders are available for use with your printer:
The asterisk (
]) is a substitute for the last digit, which varies by country. Contact 
your local EPSON dealer for the part number in your country.
You can install the high-capacity cut-sheet feeder by itself, 
or you can assemble and install a double-bin cut-sheet feeder by 
combining the high-capacity and second-bin feeders. When the 
double-bin cut-sheet feeder is installed, the high-capacity cut-
sheet feeder is used as bin 1 and the second-bin feeder is used as 
bin 2.
Note:
o
The second-bin feeder can be used only in combination with the high-
capacity feeder.
o
The second-bin feeder can not be detached from the high-capacity 
feeder after you have combined them. 
Before you install a cut-sheet feeder, read the manual that comes 
with it. The cut-sheet feeder manual provides instructions on how 
to combine the two cut-sheet feeders to create the double-bin cut-
sheet feeder.
You can load up to 150 single sheets of paper, 40 single-sheet 
multipart forms, 25 envelopes, or 50 postcards in the high-
capacity cut-sheet feeder (bin 1 of the double-bin feeder). You can 
load an additional 50 single sheets in the second-bin cut-sheet 
feeder (bin 2 of the double-bin feeder). With the double-bin cut-
sheet feeder, you can load two different types or sizes of paper at 
one time.
Note:
For detailed paper specifications, see Appendix C.

Installing the cut-sheet feeder
The cut-sheet feeder comes with a paper guide for stacking 
printed sheets. To install the cut-sheet feeder, you need to attach 
both the cut-sheet feeder and the paper guide. Follow the steps 
below.
Note:
o
The second-bin feeder can be used only in combination with the high-
capacity feeder.
o
Install both the high capacity cut-sheet feeder and the double-bin 
cut-sheet feeder the same way, as described below. Before you install 
the double-bin cut-sheet feeder, assemble it as described in the cut-
sheet feeder manual.
1. Make sure the printer is turned off.
2. Close the sprocket covers if they are open, and lock the 
sprocket units by pushing down the lock levers if necessary.
Note:
You do not need to remove your continuous paper from the tractor 
to use the cut-sheet feeder. For information on switching between 
the cut-sheet feeder and continuous paper, see Chapter 2, 
“Switching Between Continuous Paper and Single Sheets.”

printer.
4. Remove the paper guide from the front of the printer. Then 
slide the paper guide for the cut-sheet feeder all the way onto 
the mounting pegs.
5. Slide the edge guide all the way to the left.
