Paper Handling
Printing on Continuous Paper
Your printer can handle continuous paper from 101.6 mm (4.0
inches) to 254 mm (10.0 inches) wide. Depending on where you
position the tractor, you can use it as a pull tractor or a push
tractor. The following guidelines can help you decide where to
position the tractor:
❏ Do you want to switch between printing on single sheets and
continuous paper without removing the paper supply? Will
you tear off continuous paper sheet-by-sheet? Use the tractor
in the push tractor position. (The printer comes with the
tractor installed in this position.) See the following section.
❏ Are you printing on labels, multipart forms, or other
documents that require a precise print position? Use the
tractor as a pull tractor. See “Printing with the pull tractor”
on page 20 for instructions.
Printing with the push tractor
When using the push tractor, it is a good idea to set the Auto tear
off feature in the Default Setting mode to On. See “About Your
Printer’s Default Settings” on page 88.
Follow these steps to load continuous paper using the push
tractor:
15
1. Make sure the printer is turned off. Remove the printer cover
and the paper guide and place the paper release lever in the
continuous paper position.
2. Release the sprocket units by pulling the sprocket locks
forward.
16
3. Slide the left sprocket unit using the scale on the printer as a
guide. The printer prints to the right of the position marked
0. Push the sprocket lock lever back to lock it in place. Then
slide the right sprocket unit to match the width of your paper,
but do not lock it. Move the paper support so it is midway
between the sprocket units.
4. Make sure your paper has a clean, straight leading edge. Open
the sprocket covers. Fit the first holes of the paper over the
sprocket pins and then close the sprocket covers. Slide the
right sprocket unit to remove any slack in the paper and lock
it in place. Now the paper is in the paper-park position.
Caution:
Use the paper feed knob on the right side of the printer only
c
to clear paper jams and only when the printer is turned off.
Otherwise, you may damage the printer or cause it to lose the
top-of-form position.
17
5. To separate the incoming paper from the printed paper, attach
the paper guide by holding it horizontally and fitting its
notches over the printer’s mounting posts as shown below.
Then slide the paper guide toward the front of the printer until
you feel it click and adjust the edge guides to the width of the
paper.
6. Turn on the printer.
7. Make sure the printer cover is closed. Press the LF/FF button
to feed the paper to the loading position. When the printer
receives data, it begins printing automatically.
8. After you finish printing, follow the steps in the next section
to tear off your printed document. If the first printed line on
your page appears too high or low, you can change its position
by using the Micro Adjust feature. See “Adjusting the
top-of-form position” on page 25.
Caution:
Never use the paper feed knob to adjust the top-of-form position;
c
this may damage the printer or cause it to lose the top-of-form
position.
When you send more data, the paper automatically feeds back to
the loading position.
18
Removing a printed document from the push
tractor
Follow these steps to remove the printed document:
1. Press the Tear Off (Font) button. Make sure the Tear Off(Font) lights are flashing. (This indicates that your paper is at
the current tear-off position.)
2. Open the paper guide cover, then tear off the printed
document using the tear-off edge of the paper tension unit.
Note:
If your paper’s perforation is not properly 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 28.
Caution:
Never use the paper feed knob to adjust the tear-off position;
c
this may damage the printer or cause it to lose the tear-off
position.
3. Close the paper guide cover.
When you resume printing, the printer automatically feeds
the paper back to the top-of-form position and starts printing.
19
To feed continuous paper to the standby position where you can
remove the paper, press the Load/Eject button. Then open the
sprocket covers of the tractor and remove the paper.
Caution:
Always tear off your printed document before you press the
c
Load/Eject button. Reverse feeding several pages at a time may
cause a paper jam.
Switching back to single sheets
To switch to single sheets, press the Load/Eject button; the
printer feeds the paper backwards into the standby position.
Then, follow the steps in “Loading single sheets” on page 31.
Caution:
Always tear off your printed document before you press the
c
Load/Eject button. Reverse feeding several pages at a time may
cause a paper jam.
Printing with the pull tractor
To load continuous paper using the pull tractor, you must move
the tractor to the pull tractor position, as described in steps 1
through 3 in this procedure. If your tractor is already installed in
this position, make sure the printer is turned off and skip to step 6.
Caution:
❏ Use the paper feed knob on the right side of the printer only
c
to clear paper jams and only when the printer is off.
Otherwise, you may damage the printer or cause it to lose the
top-of-form position.
❏ When using the pull tractor, set the Auto tear off feature in
the Default Setting mode to Off; otherwise, the paper may
jam.
20
1. Turn the printer off; then remove the printer cover and the
paper guide. Next, remove the paper tension unit by
squeezing the paper tension unit’s lock tabs gently and
pulling the paper tension unit away from the printer. Finally,
pull the paper release lever forward to the continuous paper
position.
2. Squeeze the tractor’s lock tabs gently on both sides, and then
rotate the tractor up to pull it away from the printer.
21
3. Move the tractor forward to the mounting slot at the top of
the printer and tilt it into place as shown below. When you
push the tractor onto the posts, you should feel the notches
snap into place.
4. Release the sprocket units by pulling the sprocket locks
forward.
22
5. Insert the paper into the bottom paper slot or into the rear
paper slot as shown below, and pull it up. Position the paper
using the scale on the printer as a guide. The printer prints to
the right of the position marked 0.
6. Slide the left sprocket unit so that its sprockets match the
position of the holes in the paper and lock the unit in place.
Then slide the right sprocket unit to match the width of your
paper, but do not lock it. Move the paper support midway
between the two sprocket units.
7. Make sure your paper has a clean, straight leading edge. Open
the sprocket covers. Fit the first holes of the paper over the
sprocket pins and then close the sprocket covers. Slide the
right sprocket unit to remove any slack in the paper and then
lock it in place.
23
Note:
Remove any remaining slack by gently pulling the paper from the
rear or bottom.
8. To separate the incoming paper from the printed paper, attach
the paper guide. Hold it horizontally and fit its notches over
the printer’s mounting posts. Then slide the paper guide
toward the back of the printer until you feel it click and adjust
the edge guides to the width of the paper.
9. Attach the printer cover and adjust the paper position with
the paper feed knob. Turn the knob until the perforation
between pages is just above the print head. Then turn on the
printer.
10. Make sure the printer cover is closed, but with the paper guide
cover open. When the printer receives data, it begins printing
automatically.
If you want to change the position where printing begins on the
page, press LF/FF to advance the page to the next top-of-form
position, and then see Adjusting the top-of-form position in the
next section to adjust the loading position.
To eject the paper, tear off the paper entering the printer; then
press the LF/FF button to feed the paper forward.
24
Adjusting the top-of-form position
The top-of-form position is the position on the page where the
printer starts printing. If your printing appears too high or low
on the page, you can use the micro adjust feature to adjust the
top-of-form position. Follow these steps:
Caution:
Never use the paper feed knob to adjust the top-of-form position;
c
this may damage the printer or cause it to lose the top-of-form
position.
Note:
❏ Your top-of-form position setting remains in effect until you change
it, even if you turn off the printer.
❏ The top margin setting made in some application software overrides
the top-of-form position setting you make with the Micro Adjust
feature. If necessary, adjust the top-of-form position in your
software.
1. Make sure the printer is turned on.
2. If necessary, load paper as described in this chapter.
3. Remove the printer cover.
4. Hold down the Pause button for about three seconds. The
Pause light starts flashing and the printer enters the Micro
Adjust mode.
25
5. Press the LF/FF D button to move the top-of-form position up
on the page, or press the Load/Eject U button to move the
top-of-form position down on the page.
*
* plastic ribbon cover
Note:
❏ The printer has a minimum and a maximum top-of-form
position. If you try to adjust it beyond these limits, the printer
beeps and stops moving the paper.
26
❏ When the paper reaches the default top-of-form position, the
printer also beeps and stops moving the paper briefly. You can
use the default position as a reference point when adjusting the
top-of-form position.
To adjust the top-of-form position for continuous paper
loaded on the pull tractor, see the following example:
First mark a point 2.5 mm (0.1 inch) above the paper’s
perforation; then position the paper so that the mark is even
with the top edge of the plastic ribbon cover. This gives you
an 8.5 mm (0.33 inch) margin on the next page, meaning the
printer starts printing 8.5 mm (0.33 inch) below the
perforation. If you mark a point 2.5 mm (0.1 inch) above the
perforation, you get a 8.5 mm (0.33 inch) margin on the next
page.
A2.5 mm (0.1 inch)
B8.5 mm (0.33 inch)
6. After you set the top-of-form position, press the Pause button
to exit the Micro Adjust mode.
Advancing the paper to the tear-off edge
If you use the push tractor, you can use the tear-off feature to
advance your continuous paper to the printer’s tear-off edge
when you finish printing. You can then easily tear off the printed
document. When you resume printing, the printer automatically
feeds the paper back to the top-of-form position so that you can
save the paper normally lost between documents.
27
As described below, you can use the tear-off feature in two ways:
manually, by pressing the printer’s Tear Off (Font) button, or
automatically, by turning on the auto tear-off mode.
Caution:
Never use the tear-off feature (as described below) to feed
c
continuous paper with labels backwards; they may come off their
backing sheet and jam the printer.
Using the Tear Off button
After the printer finishes printing your document, check that the
Tear Off (Font) lights are not flashing. Then press the Tear Off
(Font) button. The printer advances the paper to the tear-off edge.
Note:
If the Tear Off (Font) lights are flashing, the paper is in the tear-off
position. If you press the Tear Off (Font) button again, the printer feeds
your paper to the next top-of-form position.
Advancing the paper to the tear-off position automatically
To automatically advance your printed documents to the tear-off
position, you need to turn on the auto tear-off mode and select
the appropriate page length for continuous paper in the Default
Setting mode. For instructions, see “Changing default settings”
on page 95.
When auto tear-off is on, the printer automatically advances the
paper to the tear-off position whenever it receives a full page of
data or a form feed command followed by no more data.
Adjusting the tear-off position
If your paper’s perforation is not aligned with the tear-off edge,
you can use the Micro Adjust feature to move the perforation to
the tear-off position.
Follow these steps to adjust the tear-off position:
28
Caution:
Never use the paper feed knob to adjust the tear-off position; this
c
may damage the printer or cause it to lose the tear-off position.
Note:
Your tear-off position setting remains in effect until you change it, even
if you turn off the printer.
1. Make sure the Tear Off (Font) lights are flashing (the paper
is at the current tear-off position). You may need to press the
Tear Off (Font) button to advance the paper to the tear-off
position.
2. Open the paper guide cover.
3. Hold down the Pause button for about three seconds. The
Pause light begins to flash and the printer enters the Micro
Adjust mode.
4. Press the LF/FF D button to feed the paper backwards, or press
the Load/Eject U button to feed the paper forwards, until the
paper perforation is aligned with the tear-off edge.
