Site Requirements

CAUTION: To insure that the printer has proper ventilation and cooling,
do not place any padding or cushioning material under the unit, because
this restricts air flow.

This printer may be installed on any solid, level surface of sufficient size
and strength to accommodate the physical dimensions and weight of the
unit. The area enclosure in which the printer will operate must meet the
environmental conditions specified. Electrical power must be available and in
close proximity to the printer.

Since this printer was designed and is fabricated as an industrial-type unit, it
will function satisfactorily in areas such as warehouses, factory floors, and
office environments that conform to specified environmental and electrical
conditions.

Introduction to Printers

The first thing you want to do is identify your printer. This makes certain
tasks -- such as media loading -- much easier to do!

If your printer
looks like this
(Figure 1), it is
set up for
Tear-Off mode.
Tear-Off allows
you to tear away
each label, or a
strip of labels,
after it is
printed.

To load media,
refer to
“Loading the
Media -­Tear-Off Mode”
in Getting Ready
to Print.

Figure 1

Figure 2

S400 & S600 User’s Guide 3

Backing

Rewind Spindle

This printer
(Figure 2)
operates in
Peel-Off mode.
In Peel-Off,
backing material
is peeled away
from the label as
it is printed.
After this label is
removed from the
printer, the next
one is printed.

To load media,
refer to “Loading
the Media -­Peel-Off Mode”
in Getting Ready
to Print.

Cutter

Module

Printers like this
(Figure 3) are
equipped for
Cutter mode.
When in cutter
mode, the printer
automatically
cuts the label
after it is printed.
Then, the cutter
catch tray
“catches” the
label.

To load the
media, refer to
“Loading the
Media -- Cutter
Mode” in Getting
Ready to Print.

Removing the Label Backing Material

quired)

(Peel-Off Option Re-

When the amount of backing wound on the backing rewind spindle reaches
full capacity, the backing rewind spindle full sensor activates, the
paper/ribbon light flashes, and printing pauses.

To remove the backing material, follow these steps (you don’t need to
power off the printer for this procedure):

1. Unwind about 24" of backing from the backing rewind spindle and cut it

off at the spindle.

2. Pull out the hold down hook and slide the backing material off of the

spindle and discard.

3. Feed the new starting edge of the backing through the mechanism and

attach it to the backing rewind spindle as described in the loading proce­dure.

NOTE: While holding the media in position against the tear-off/peel-off
plate, open and close the printhead without disturbing the media position.
The printer is now ready to print more labels.

S400 & S600 User’s Guide 11

Cutter Mode (Optional)

To insure proper media loading, follow the directions for the Tear-Off
Mode with the exception that the end of the media must be positioned on
top of the platen roller. See Figure 10.

With the end of the media positioned directly on top of the platen roller (a),
close the head open lever. The printer will automatically calibrate, feed out,
and cut the label when the printer is powered on or the printhead is opened
and closed.

Loading the Ribbon

Before you load the ribbon, make sure the ribbon supply spindle is adjusted
properly.

Ribbon Supply Spindle: Normal Position

In the normal position, the “dual-tension” ribbon supply spindle provides
the desired amount of ribbon back tension for different ribbon widths.

To place the spindle in the normal position, firmly pull the spindle end cap
(a) until it clicks into place, as shown in Figure 11.

Ribbon Supply Spindle: Low-Tension Position

Low-tension position is used in limited applications to provide lower ribbon
back tension. Low-tension position is only recommended when normal
tension hampers the ribbon movement (for example, you will see scuffing
or image breakup on the label).

To put the spindle in the low-tension position, firmly push the spindle end
cap (a) until it clicks into place, as shown in Figure 11.

Ribbon Loading Instructions

NOTES:

n

Zebra recommends the use of ribbon that is wider than the media. The
smooth backing of the ribbon protects the printhead from wear and
premature failure due to excessive abrasion. (For the direct thermal
print method, ribbon is not used and should not be loaded in the
printer.)

n

Zebra recommends the use of ribbon that is outside wound (the ink side
is on the outside of the roll).

To load ribbon, see Figure 12 and follow the procedure below.

1. Adjust the ribbon supply spindle position for normal or low tension.

2. Align the blades (b) on the two sections of the spindle as shown in

Figure 11. (You do not need to do this if your ribbon width is 2.4"
[60 mm] or less.)

3. Place the ribbon roll on the ribbon supply spindle (a). Make sure the roll

is pushed in to the stop at the end of the spindle.

4. Open the printhead by moving the head open lever (b) counterclockwise

to the open position.

5. Thread the ribbon as shown. Wind the ribbon onto the ribbon takeup

spindle (c) for several turns in a clockwise direction until wrinkles and
creases disappear.

6. Close the printhead by moving the lever clockwise to the closed posi-

tion.

14 S400 & S600 User’s Guide

Ribbon Removal

Refer to Figure 12.

When it’s time to change the ribbon, cut the ribbon where it is stretched
between the upper ribbon guide arm and the takeup spindle. To remove
ribbon from the takeup spindle, press the release button (d) and slide the
ribbon off the spindle.

S400 & S600 User’s Guide 15

Adjusting the Media Sensor

This adjustment aligns the position of the light sensor with the notch or
edge of the label, so the printer can determine the correct label size.

See Figure 13. With the printhead open, look through the side of the print
mechanism and locate the media sensor adjustment lever (a). Reposition
the sensor until the top of the adjustment lever is in line with the notch or
web in the media or the edge of the label. Close the printhead by moving
the head open lever to the closed position.

When continuous media (no notch or opening to sense) is used, position the
media sensor anywhere over the media so that an “out-of-media” condition
will still be sensed.

Non-Continuous Media

This type of media has some type of physical characteristic (web, notch,
perforation, etc.) that indicates the start/end of each label.

The media sensor must be properly positioned to sense these indicators.
See “Adjusting the Media Sensor” (above). Then, turn on the printer. If the
printer will not auto calibrate, press the MODE button three times, and then
the FEED button once, to manually calibrate (a label will print that shows
the sensor profile).

Continuous Media

Since continuous media does not contain label start/end indicators, you
must tell the printer via software how long each label is. If you are using
ZPL or ZPL II, include a Label Length (^LL) instruction in each label
format you send to the printer (refer to your ZPL II Programming Guide).
If you are using other software to operate your printer, refer to the
instructions provided with that software.

a

Figure 13

16 S400 & S600 User’s Guide

Auto Calibration

This procedure occurs whenever the printer is turned on or the printhead is
opened and closed. During this procedure, the printer automatically
determines the media type, label length, media and ribbon sensor settings,
and printing method (direct thermal or thermal transfer). This procedure is
set at the factory but may be changed via ZPL II command.

NOTE: If the printer fails to auto calibrate when you are using pre-printed
labels or pre-printed label backing, or if the printer will not auto calibrate,
see “Manual Calibration” in Troubleshooting.

1. Load the media and ribbon (if used).

2. Turn on the printer power.

3. Two or three blank labels will feed, completing auto calibration.

AC Power ON/OFF Switch

This switch is located on the left side of the printer near the AC power cord
and fuse (see Figure 6). The AC power switch should be turned off before
connecting or disconnecting any cables.

Turning the switch on activates the printer and causes it to perform a Power
ON Self Test, which can take up to 30 seconds, as it begins operation.
Turning the printer power on while holding down certain front panel keys
will activate additional printer self tests following the Power ON Self Test.
See Troubleshooting.

External influences, such as lightning storms or unwanted noise on the
power or data cables, may cause erratic printer behavior. Turning the AC
power off and back on may re-establish proper printer operation.
Otherwise, see Troubleshooting.

Printing a Test Label

Before you connect the printer to your computer, make sure that the printer
is in proper working order. You can do this by printing a configuration
label (refer to the “CANCEL Key Self Test” in Troubleshooting.) If you
can’t get this label to print, refer to Troubleshooting.

To make print quality adjustments, refer to “Print Quality Adjustments” in
Routine Care and Adjustments.

Connecting the Printer and Computer

This printer comes with both a nine-pin Electronics Industries Association
(EIA) RS-232 serial data interface and an IEEE 1284 bi-directional parallel
data interface. In either case, you must supply the required interface cable
for your application.

CAUTION: This printer complies with FCC “Rules and Regulations,”
Part 15, for Class B Equipment, using fully shielded six-foot data cables.
Use of longer cables or unshielded cables may increase radiated emis­sions above the Class B limits.

RS-232 Interface Requirements

Refer to Figure 6.

The required cable must have a 9-pin “D” type (DB-9P) connector (male)
on one end, which is plugged into the mating (DB-9S) connector (female)
located inside the access opening on the left side of the printer.

The other end of the signal interface cable connects to a serial port at the
host computer. This cable will be one of two types -- standard or null
modem -- depending on the specific interface requirements.

S400 & S600 User’s Guide 19

For pinout information, as well as information on how to interconnect to
either a DTE or DCE device, refer to the Appendix.

Parallel Interface Requirements

Refer to Figure 6.

An IEEE 1284 compatible bi-directional parallel data cable is required
when this communication method is selected. The required cable must have
a standard 36-pin parallel connector on one end, which is plugged into the
mating connector located inside the access opening on the left side of the
printer. The parallel interface cable is connected using bail clips instead of
screws.

The other end of the parallel interface cable connects to the printer
connector at the host computer.

For pinout information, refer to the Appendix.

Serial and Parallel Cabling Requirements

Data cables must be fully shielded and fitted with metal or metallized
connector shells. Shielded cables and connectors are required to prevent
radiation and reception of electrical noise.

To minimize electrical noise pickup in the cable:

1. Keep data cables as short as possible.

2. Do not bundle the data cables tightly with power cords.

3. Do not tie the data cables to power wire conduits.

Communicating with the Printer

Via the Parallel Port

n

Set the parallel connection on the host computer. For instructions, refer
to your computer’s user’s guide.

Via the Serial Port

n

Set the host computer to the factory defaults of the printer: 9600 baud, 8
bit word length, no parity, 1 stop bit, and XON/XOFF. For instructions,
refer to your computer’s user’s guide.

NOTE: If you can’t reset the host computer communications settings, then
you must establish a temporary parallel connection to send down the Set

buttons when the CALIBRATE LED goes out. All of the LEDs will go on,
while the DARKEN, POSITION, and CALIBRATE LEDs will flash. Press
and hold the MODE button until all of the lights go out, then release the
MODE button. The factory defaults have now been reset. Next, set the
communications parameters on your computer to match this.

NOTE: To save the default settings, press the MODE button four times.
Otherwise, the previous settings will be restored the next time the printer is
turned on.

AUTOBAUD: To automatically detect the communications parameters,
press and hold the PAUSE, FEED, and MODE buttons while turning on the
printer, then release the buttons when the CALIBRATE LED goes out. All
of the LEDs will go on, while DARKEN, POSITION, and CALIBRATE
LEDs will flash. Send a label format using the host computer settings. If
the printer accepts the host parameters, all of the LEDs will go off (except
for the POWER LED) and the printer will restart with the host
communication settings. If the printer does not accept the host
communications parameters, the printer will not restart and the LEDs will
flash on and off. If this should happen, turn the printer off and then on, and
try again.

NOTES: Label formats sent to the printer at this time only help the printer
determine the host settings. No label will print until settings are recognized.

In order for autobaud to work, your label must start with either a ^XA or
~XA ZPL II command. If all the LEDs are on, send another label format.

Save the new communication settings by pressing MODE four times.

Autobaud only works for 9600 baud and higher.

^SC: Use the Set Communications (^SC) command to change the
communications settings on the printer. 1) With the host computer set at
the same communications settings as the printer, send the ^SC command to
change the printer to the desired settings. 2) Then, change the host
computer settings to match the printer settings.

Setting Up the Software

In order to create labels, you must decide whether you will use ZPL II or
commercial label preparation software. To use ZPL II, refer to the ZPL II
Programming Guide. If you choose to use a label preparation software,
follow the installation instructions included in the package.

Cleaning the Exterior

The exterior surfaces of the printer may be cleaned with a lint-free cloth.
Do not use harsh or abrasive cleaning agents or solvents. If necessary, a
mild detergent solution or desktop cleaner may be used sparingly.

Cleaning the Interior

Remove any accumulated dirt and lint from the interior of the printer using
a soft bristle brush and/or vacuum cleaner. Inspect this area after every roll
of media.

Cleaning the Printhead and Platen Roller

Inconsistent print quality, such as voids in the bar code or graphics, may
indicate a dirty printhead. For optimum performance, perform the
following cleaning procedure after every roll of ribbon.

NOTE: It is not necessary to turn the printer off before cleaning the
printhead. If power is turned off, all label formats and images, as well as
any temporarily saved parameter settings stored in the printer’s DRAM
memory, will be lost. When power is turned back on, it will be necessary to
reload these items.

To clean the printhead, refer to Figure 16 and follow these steps:

1. Open the media access cover and the front cover (see Figure 4).

b

d

Figure 16

a

24 S400 & S600 User’s Guide

2. Open the printhead (a) by moving the head open lever (b) to the open

position.

3. Remove the media and ribbon (if present).

4. With a swab, wipe the print elements (c) from end to end (the print ele-

ments are the grayish/black strip just behind the chrome strip.) Allow a
few seconds for the solvent to evaporate.

5. Rotate the platen roller (d) and clean thoroughly with alcohol.

6. Brush/vacuum any accumulated paper lint and dust away from the roll-

ers and media sensors.

7. Reload ribbon and/or media, close and latch the printhead, close the

front cover and the media access cover, and continue printing.

If print quality has not improved after performing this procedure, try
cleaning the printhead with Save-a-Printhead cleaning film. This specially
coated material removes contamination buildup without damaging the
printhead. Call your authorized Zebra distributor for more information.

Cleaning the Cutter Module (for Printers
Equipped with the Optional Cutter)

The cutter module requires periodic cleaning to remove paper dust and
gummed label residue. The procedure on the following pages should be
performed by the operator according to the cleaning schedule table.
However, depending on your application and media type, you may need to
clean the cutter more or less frequently.

NOTE: In the figures shown, media and ribbon have been removed for
clarity. It is not necessary to remove media or ribbon before performing the
maintenance procedures described.

IMPORTANT: Do not exchange cutter modules between different
printers. The cutter module adjustments are optimized during installation to
work with a particular printer and may not perform correctly if the module
is placed on a different printer.

I. Removing the cutter module from the printer.

S400 & S600 User’s Guide 31

Mechanical Adjustments

This printer has been designed with minimal operator adjustments required.

Print Quality Adjustments

When changing from one media/ribbon combination to another, only slight
changes in print darkness or toggle pressure may be required. For these
situations, refer to the toggle pressure adjustment in this chapter.

I. Checking the initial print quality.

Open the media access cover and front cover on the printer (see

1.
Figure 4).

Load the recommended media and ribbon for your application and adjust the

2.
media sensor position.

Send a label format to the printer or activate the PAUSE key self test (see

3.

Troubleshooting), print a few labels, and press the PAUSE button to stop
printing.

Observe the print quality of the test labels. If it is satisfactory, exit the PAUSE

4.

key self test by pressing and holding the CANCEL button until the DATA LED
goes off. Otherwise, continue to step II.

II. Adjusting the print darkness (burn temperature).

Press the MODE button once (DARKEN and PAUSE LEDs turn on) to permit

1.
darkness adjustment.

2.

Press the PAUSE button to begin printing test labels.

While observing the print darkness, repeatedly press the UP (FEED) button to

3.

make the printing darker, or the DOWN (CANCEL) button to make the printing
lighter, until the desired darkness is achieved.

Briefly press the MODE button three times. The MODE LEDs will flash on and

4.
off to indicate that the settings have been saved in memory.

5.

Press the PAUSE button to stop printing.

NOTE: To confirm the change, turn off the printer. Then, turn on the printer
while holding the CANCEL button.

If you are still experiencing poor print quality, perform the following toggle
pressure adjustment. Otherwise, exit the PAUSE key self test by pressing
and holding the CANCEL button until the DATA LED goes off.

Toggle Pressure Adjustment

The toggle assembly presses the printhead against the ribbon (if used), the
media, and the platen.

32 S400 & S600 User’s Guide

The pressure applied by the toggle assembly may need to be increased or
reduced when different thicknesses or widths of media are used in the
printer.

NOTE: Before increasing toggle pressure to achieve darker print darkness,
perform the print quality adjustments.

Refer to Figure 23. Turn the two knurled toggle pressure adjust knobs (a)
on top of the toggle assembly to adjust the pressure. Turning clockwise will
increase the pressure, and turning counterclockwise will decrease the
pressure.

Always use the lowest toggle pressure necessary to provide the desired print
darkness on the label.

NOTE: When using media narrower than 4.5" wide (full media width),
reduce the pressure on the right hand toggle until print quality is affected,
then increase pressure just to the point where good print quality is achieved.
This reduces the wear on those areas of the printhead and the platen where
ribbon and media are not present. (For very narrow media, zero pressure
from the right toggle may be required.)

Backing Rewind Power Roller Adjustment

(PEEL-OFF OPTION REQUIRED)

NOTE: This roller is only present on printers with the Peel-Off option.
Zebra presets this roller during manufacture for proper operation with most
applications. Only adjust this roller when necessary.

In the Peel-Off mode, proper media tracking is critical. The rewind power
roller automatically turns along with the movement of media, to insure
continuous rewind of the label backing material. When adjusting this roller,
the operating position may vary due to the type, width, and thickness of the
backing material.

Before performing this adjustment, review the media loading procedure in
Getting Ready to Print. Insure minimal sideways movement during the
printing process by positioning the left edge of the label backing even with
the edge guide mark on the tear-off/peel-off plate. Position the media
guides against the outside (right) edge of the media, but not so tight as to
bind the material.

When the power roller is properly adjusted, the backing material should
have even tension across its entire width and be wrapped snugly around all
guides and rollers. If the tension is not even, the media/backing material
may slide (walk) to the left or to the right as printing occurs. This can cause
print registration problems on the labels.

S400 & S600 User’s Guide 35

Figure 24 illustrates an improperly adjusted backing rewind power
roller (a). On the left side, the backing material (b) is not contacting the
power roller. The backing has more tension on the right edge (c) than on
the left edge (d).

Use a coin or screwdriver to turn the power roller adjustment (e). The
adjustment mechanism changes the position of the right end of the roller,
while the left end is stationary. The right end moves up and down for
tension balance.

Turning this adjustment in a counterclockwise direction causes the right end
of the power roller to move down and increases the tension on the right side
of the backing material. (Turning the adjustment in a clockwise direction
moves the right end of the power roller up and decreases the tension on the
right side.)

Balancing the tension increases the reliability of the printer to provide
properly printed labels by preventing the label backing from walking.

Use the FEED key self test (see Troubleshooting) or your own label format
to print several labels to insure tracking is maintained and tension on both
edges of the backing material remains consistent. Remember to remove
each label as it is automatically peeled away from the backing.

Manual Calibration

Perform a manual calibration whenever you are using pre-printed
media, if the printer is in manual calibration mode, or when the printer
will not auto calibrate.

During this procedure, the media type, label length, media and ribbon
sensor settings, and printing method are determined. Media type is
determined by sensing either continuous or non-continuous media as blank
labels move through the printer. If non-continuous media is sensed, label
length is also calibrated. If ribbon is sensed, the thermal transfer print
method is configured; otherwise, the direct thermal print method is
configured.

The results of this calibration are stored in the printer’s memory and are
retained even if printer power is removed. These parameters remain in
effect until the next calibration is performed.

NOTES: This procedure should only be done once to put the printer into
manual calibration. After that, press the MODE button three times and the
FEED button once when you change media (a label will print that shows the
sensor profile).

If the printer is in the Peel-Off mode, the operator must “catch” the labels as
they are peeled away from the backing during this procedure.

1. Place the head open lever in the open position.

2. Remove the ribbon.

3. Remove approximately 6” of labels from the media roll, enough so that
only the backing material is threaded under the media sensor when the
media is loaded.

4. Reload the media.

5. Press and hold down the PAUSE, FEED, and CANCEL buttons.

6. Turn on the power switch.

7. After the CALIBRATE LED goes out, release the PAUSE, FEED, and
CANCEL buttons.

8. When the PRINTHEAD LED flashes, reload the ribbon.

9. Make sure the media sensor is properly positioned.

10.Close the printhead.

11.A media and ribbon sensor profile will print.

NOTE: To return to Auto Calibration, press and hold the PAUSE,
CANCEL, and MODE buttons when you turn on the printer.

Printer Diagnostics

Power-On Self Test

A Power-On Self Test (POST) is performed automatically each time the printer
is turned on. This test checks for proper initialization of various electronic
circuits and establishes starting parameters as those stored in the printer’s
memory. During this test sequence, the front panel lights will turn on and off to
insure proper operation.

At the end of this self test, only the POWER LED will remain lit. If other
LEDs are also lit, refer to the troubleshooting table.

Additional Printer Self Tests

These self tests produce sample labels and provide specific information that
help the operator determine the operating conditions for the printer.

Each self test is enabled by holding in a specific front panel button while
turning the power switch on. Keep the button depressed until the
CALIBRATE LED goes out. When the Power-On Self Test is complete,
the selected printer self test will automatically start. To return to printing
mode, turn off and then turn on the printer.

NOTES:

n

When performing self tests, disconnect all communications interface
cables from the printer.

n

When canceling a self test before its actual completion, always turn the
printer power switch off and back on.

n

When performing these self tests while in the Peel-Off mode, the
operator must remove the labels as they become available.

n

When the cutter option is installed and enabled, the labels printed in
these self tests should be automatically cut as they are printed.

48 S400 & S600 User’s Guide

CANCEL Key Self Test

pauses the printer. Each time the PAUSE button is pressed, an
additional 15 labels will print, up to 9999 labels.

n

While the printer is paused, pressing the CANCEL button once alters the
self test. Now each time the PAUSE button is pressed, the printer prints
15 labels at maximum speed, up to 9999 labels.

n

While the printer is paused, pressing the CANCEL button a second time
alters the self test again. Now each time the PAUSE button is pressed,
the printer prints 50 labels at 2.4”/second, up to 9999 labels.

n

While the printer is paused, pressing the CANCEL button alters the self
test a third time. Now each time the PAUSE button is pressed, the
printer prints 50 labels at maximum speed, up to 9999 labels.

The FEED key self test
labels will print at
various plus or minus
darkness settings relative
to the current darkness
setting. Inspect these
printouts and determine
which printout has the
best darkness setting.

n

The value on that
printout is added to
(plus) or subtracted from
(minus) the current
darkness value. (For
example, relative
darkness is “5,” so add
that to the number on the
current configuration
label [see the next step]
for the new darkness
setting.)

n

Increments to the actual
darkness value can be
programmed into the
label formats sent to the
printer. To see the actual
value of the current
darkness setting, perform a CANCEL key self test: the value will print
on the configuration printout.

To adjust print darkness, refer to “Print Quality Adjustments” in Routine
Care and Adjustments.

Storage and Reshipping

If you are not placing the printer into operation immediately, repackage it
using the original packing materials. The printer may be stored under the
following conditions:

n

Temperature: -40° to 140° F (-40 to 60° C)

n

Relative humidity: 5% to 85% non-condensing

To ship the printer, carefully pack it in a suitable container to avoid damage
during transit. Whenever possible, use the original container from the
factory. A shipping container can be purchased from Zebra Technologies
Corporation, if the original one has been lost or destroyed.

If you use a different container, package the printer carefully to avoid
damage.

CAUTION: When packaging the printer in a rigid container, use shock
mounts or shock-absorbing packing material. A rigid container will allow
shock on the outside to be transmitted undamped to the printer which may
cause damage. Also, before packing, remove all ribbon and media from the
supply and take-up spindles to prevent damage to the printer.

S400 & S600 User’s Guide 63

Glossary

alphanumeric Indicating letters, numerals, and characters such as punctuation

marks.

backfeed Backfeed is when the printer pulls the media and ribbon (if used)

backward into the printer so that the beginning of the label to be printed is
properly positioned behind the printhead. Backfeed occurs when you’re
operating the printer in tear-off, peel-off, or cutter mode.

bar code A code by which alphanumeric characters can be represented by a series

of adjacent stripes of different widths. Many different code schemes exist,
such as the universal product code (UPC) or Code 39.

calibration (of a printer) A process in which the printer determines some basic

information needed to print accurately with a particular media/ribbon
combination. To do this, the printer feeds some media and ribbon (if used)
through the printer and senses whether to use the direct thermal or thermal
transfer print method, whether continuous or non-continuous media will be
used, and (if non-continuous media) the length of individual labels/tags.

character set The set of all letters, numerals, punctuation marks, and other

characters that can be expressed by a particular barcode.

check digit A character added to a barcode symbol that indicates to the scanner

that it has read the symbol correctly.

continuous media Label or tagstock that has no web (space between labels),

notch, or gap to separate each label/tag, but rather the media is one long piece
of material.

core diameter The inside diameter of the cardboard core at the center of a roll of

media/ribbon.

cutter A device that can cut each label/tag immediately after it is printed.

diagnostics Information about what printer functions are not working. This

information is used for troubleshooting problems.

direct thermal printing Printing in which direct thermal media is used. No

ribbon is used. Instead, the media is coated with a substance that reacts to
heat to produce an image.

fanfold media Media that comes folded in a rectangular stack, rather than on a

roll.

64 S400 & S600 User’s Guide

font A complete set of alphanumeric characters in one style of type. Example:

Times, Helvetica.

ips “inches-per-second” The speed at which the label or tag is printed. Zebra

offers printers that can print from 2 ips to 12 ips.

label An adhesive-backed piece of paper, plastic, or other material on which

information is printed.

label available sensor For printers equipped with the Peel-Off option, this sensor

detects a printed label waiting to be taken or “picked” by the operator. While
it detects this label, the printer will not print additional labels. Once the label
has been taken, printing resumes. Also called “take-label sensor.”

label backing (label liner) The material on which labels are affixed during

manufacture and which is discarded or recycled by the end-users. Label
backing (or liner) has a non-stick surface that allows the label to be easily
removed by the end-user and placed in the desired location.

media Material onto which data is printed by the printer. Types of media include:

tagstock, continuous, fanfold, roll, etc.

media sensor This sensor is located behind the printhead to detect the presence of

media and, for non-continuous media, the position of the web, hole, or notch
that separates each label.

media supply spindle The rotating arm that supports media rolls and provides

consistent media feed to the printhead.

non-volatile memory Electronic memory that retains data even when power is

removed.

print speed The speed at which printing occurs. For thermal transfer printers,

this speed is expressed in terms of ips (inches per second).

printhead wear The degradation of the surface of the printhead and/or the print

elements over time. Heat and abrasion can cause printhead wear. Therefore,
to maximize the life of your printhead use the lowest print darkness setting
(sometimes called “burn temperature” or “head temperature”) and the lowest
printhead/toggle pressure necessary. Also, use ribbon that is as wide or wider
than the media, to protect the printhead from the rougher media.

registration Alignment of printing with respect to the top of a label/tag.

ribbon A band of inked material that is pressed by the printhead against the

media to transfer an image onto the media, which in turn is pressed against the
platen. A ribbon consists of a base film coated with wax or resin “ink.” Zebra

S400 & S600 User’s Guide 65

ribbons also have a back coating that protects the printhead from damage.
The ribbon transfers ink onto the media when heated by the printhead.

ribbon wrinkle A wrinkling of the ribbon caused by improper alignment of the

strip plate and/or printhead pressure. This wrinkle can be seen just above the
strip plate. Ribbon wrinkle can cause voids in the print and/or the spent
ribbon to rewind unevenly. This is a condition that should be corrected by
performing adjustment procedures.

roll media Media that comes supplied rolled up on a core (usually cardboard).

Contrast this with fanfold media, which comes folded in a rectangular stack.

Supplies Supplies is a general term for ribbon and media.

Tag A type of media having no adhesive backing but featuring a hole or notch by

which the tag can be hung on something. Usually tags are made of cardboard
or other durable material.

take label sensor See “label available sensor.”

thermal direct printing See “direct thermal printing.”

thermal transfer printing A printing method in which the printhead heats an

ink- or resin-coated ribbon against the media, causing the ink/resin to transfer
onto the media. By selectively heating the ribbon, you can form an image on
the media. See also “ribbon.”

void A space where printing should have occurred but, due to some error

condition, it did not occur. A void can cause a bar code symbol to be read
incorrectly or to not be read at all.
