Using the Tear-off Function
When you have finished printing, you can use the tear-off
function to advance continuous paper on the tractor to the
tear-off edge of the printer and tear off the printed sheets. When
you resume printing, the printer automatically feeds paper back
to the loading position so you can save paper that would
normally be lost between documents.
You can use the tear-off function two ways:
❏ Press the Tear Off button on the control panel
It is best to select
Auto for all types of paper. This lets the
printer automatically adjust itself to match the thickness each
time it loads new paper. Note that printing time may be slowed.
If you use the same type of paper every time, you may want to
set the paper thickness lever to the appropriate manual position
as described in the following table. This speeds up printing.
8 - EPSON LQ-680Pro 11/00
❏ Use the default setting mode or the EPSON Remote! utility
to select auto tear-off. (See “Changing the Default Settings”
on page 14 for more information.)
If the perforation between pages is not aligned with the tear-off
edge, you can adjust the tear-off position using the micro adjust
feature. See “Adjusting the Tear-off Position” on page 12.
Never use the tear-off function to feed labels backward;
they may come off their backing and jam the printer.
Page 9
EPSON LQ-680Pro
Using the Tear Off Button
You can use the Tear Off/Special Paper button to advance
continuous paper to the tear-off position as follows:
1. Make sure printing has finished. Then press the
Tear Off
button until the two lights on the control panel start
flashing. The printer advances the paper to the tear-off edge.
2. Tear off all printed pages at the tear-off edge. If the
perforation is not aligned with the edge, adjust the tear-off
position using the micro adjust feature. See “Adjusting the
Tear-off Position” on page 12.
3. When you resume printing, the printer feeds the paper back
to the top-of-form position and begins printing. (You can
also manually feed the paper back to the top-of-form
position by pressing the same button used to advance the
paper.)
Using Auto Tear-off Mode
When you turn on the auto tear-off function in the printer’s
default-setting mode or the EPSON Remote! utility, the printer
advances continuous paper to the tear-off position when you
finish printing.
The printer advances paper to the tear-off position only when it
receives a full page of data or a form-feed command and then
receives no more data for three seconds.
For instructions on how to activate the auto tear-off function,
see “Changing the Default Settings” on page 14 or use the
EPSON Remote! utility (described in the User’s Guide). While
using the default setting mode or the utility, also make sure the
page length is set correctly for your continuous paper.
After the paper has been advanced, tear off all printed pages and
resume printing. You can leave the auto tear-off mode on even
when you are using single sheets; the mode is disabled while you
are using single sheets.
Removing Continuous Paper
1. After you finish printing, tear-off all printed pages using the
tear-off function.
2. Press the
Load/Eject button to feed the continuous paper
backward out of the printer and into the standby position.
3. To completely remove continuous paper from the printer,
open the sprocket covers. Remove the paper from the
tractor unit, and then close the sprocket covers.
Using Continuous Multipart Forms
Your printer can use continuous multipart forms with up to six
parts including the original. You can use carbonless or
carbon-backed multipart forms.
Do not use carbon-interleaved multipart forms.
Before printing, make sure the paper thickness lever is set to the
Auto position.
You can load continuous multipart forms the same way you
load ordinary continuous paper. For instructions, see the
User’s Guide.
When printing on multipart forms, make sure that your
software settings keep the printing entirely within the
printable area of the forms. Printing on the edge of a
multipart form can damage the print head. For more
information, see “Printable Area” on page 5.
Using Overlapping Multipart Forms
You can print on overlapping multipart forms backed with
continuous paper. The page length of the multipart forms is
longer than that of the backing continuous paper. So when
extended, one page’s multipart forms overlap the next page’s
multipart forms. The thickness of this overlapping area is
thicker than the printable area.
Before printing, set the paper thickness lever to the
position. Also turn on both the overlapping-forms and the
skip-over-perforation settings using the default setting mode.
See “Adjusting the Paper Thickness Lever” on page 8 and
“Changing the Default Settings” on page 14 for more
information.
You can load continuous multipart forms the same way you
load ordinary continuous paper. (For instructions, see the
User’s Guide.)

EPSON LQ-680Pro
When printing on overlapping multipart forms, make
sure that your software settings keep the printing
entirely within the printable area of the forms. Printing
on the edge of a multipart form can damage the print
head. For more information, see “Printable Area” on
page 5.
Never feed overlapping multipart forms backward with
the Load/Eject or Tear Off/Special Paper buttons. Doing
so may cause paper jams or damage to the printer.
To remove overlapping multipart forms from the paper
path after you finish printing, first tear off the paper at a
point before the paper slot. Then use the LF/FF button
to advance the remaining paper out of the printer.
Using Labels
When selecting labels for printing, always choose labels
mounted on continuous backing sheets with sprocket holes for
use with a tractor. Do not use labels on shiny single-sheet
backing, because the backing sheet tends to slip and may not
feed properly.
Load labels the same way you load ordinary continuous paper,
and set the paper thickness lever to the
manually to
2 for faster throughput. See “Adjusting the Paper
Thickness Lever” on page 8.
When pr inting on labels, make sure that your software
settings keep the printing entirely within the printable
area. Printing on the edge of a label can damage the
print head.
Never feed labels backward with the Tear Off/Special
Paper button. Labels can easily peel off their backing
and jam the printer.
To remove labels from the paper path after you finish
printing, first tear off the labels at a point before the
paper slot. Then use the LF/FF button to advance the
remaining labels out of the printer.
Because labels are especially sensitive to temperature
and humidity, use them only under normal operating
conditions.
Do not leave labels loaded in the printer between print
jobs; they tend to curl and may come off their backing
and jam the printer when you resume printing.

6. When you finish, turn off the printer to exit the default
setting mode. The current settings remain in effect until
you change them again.
Bidirectional Alignment
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.
To complete the steps below, you need 5 single sheets
or 5 pages of continuous paper that are at least
11 inches (279 mm) long and 9.5 inches (241 mm)
wide. If you use single sheets without a cut-sheet
feeder, you need to load a new sheet of paper each
time the printer ejects a printed sheet onto the paper
guide.
1. Make sure paper is loaded and the printer is turned off.
Whenever you turn off the printer, wait at least 5
seconds before turning it back on; otherwise you may
damage the printer.
2. While holding down the Pause button, turn on the printer.
It enters the bidirectional adjustment mode, 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.
Either self test can help you determine the source of your
printing problem; however, the draft test prints faster than
the letter-quality test.
After a few seconds, the printer loads the paper
automatically and begins printing the self test. A series of
characters is printed.
To temporarily stop the self test, press the P ause
button. To resume the test, press the Pause button
again.
3. To end the self test, press the Pause button to stop
printing. Then turn off the printer.
If 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.)
If the self test does not print properly, there is a problem with
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.
Use continuous paper that is at least 9.5 inches
(241 mm) wide (or A4 or letter-size single sheets).
Printing a Self Test
Running the self test helps you determine whether the printer
or the computer is causing a printing problem. You can print
the self test using either single sheets or continuous paper.
1. Make sure paper is loaded and the printer is turned off.
Whenever you turn off the printer, wait at least 5
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.
1. Make sure paper is loaded and the printer is turned off.
Whenever you turn off the printer, wait at least 5
seconds before turning it back on; otherwise you may
damage the printer.
2. To enter hex dump mode, hold down both the LF/FF and
Load/Eject buttons while you turn on the printer.
3. Open a software application and send a print job to the
printer. Your printer prints all the codes it receives in
hexadecimal format.

If characters are printable, they appear in the right column
as ASCII characters. Nonprintable codes, such as control
codes, are represented by dots. By comparing the characters
printed in the right column with the printout of the
hexadecimal codes, you can check the codes the printer is
receiving.
4. To exit hex dump mode, press the
Pause button to stop
printing. Then eject or tear off the printed page(s) and turn
off the printer.
Cleaning the Printer
1. Remove any paper loaded in the printer and turn it off.
2. Unplug the power cord from the electrical outlet; then
disconnect the interface cable from the printer.
3. Remove the paper guide. If a pull tractor or an optional
cut-sheet feeder is installed, remove it.
4. Use a soft brush to carefully brush away all dust and dirt
from the outer case and paper guide.
5. If the outer case or paper guide is still dirty, clean it with a
soft, clean cloth dampened with mild detergent dissolved in
water. Keep the printer cover closed to prevent water from
getting inside the printer.
Never use alcohols or thinners to clean the printer;
these chemicals can damage the printer components
as well as the case.
Be careful not to get water on the printer mechanism or
electronic components.
Do not use a hard or abrasive brush.
Do not spray the inside of the printer with lubricants;
unsuitable lubricants can damage the printer
mechanism. Contact an EPSON dealer if you think
lubrication is needed.
