Positioning The Air Jets
When a printed label is being fed from the SLPA onto the applicator pad, it
must be held against the pad so that it can be properly positioned. The air jets
located on the air jet tube direct air at the label while it is being fed, so that it
does not bend or fall from the pad. Once proper positioning is achieved, the
vacuum of the applicator pad initiates and holds the label into place until
application.
For the air jets to work correctly, they must be directed at an angle specific to
the size of the label in use. Angle the air jets to a point which is approximately
1/3 the length of the current label length, as measured from the peel bar.
Wider or longer labels may approximate the air jet angle to a point beyond 1/3
the label length, where shorter or narrower labels may target inside the 1/3
length zone. Repeated adjustment may prove necessary for optimum
operation.

1. Loosen the socket head screw holding the air tube into place.
2. Ensure that the proper holes in the air jet are open. The standard tube
comes with #2-56NC threaded holes and some of the holes may be
plugged with a small set screw. Add or remove set screws as necessary.
3. Turn the air tube adjustment so that the air jets are directed at
approximately 1/3 the length of the current label length as measured from
the peel bar.
4. Tighten the socket head screw into place to hold this adjustment.

Calibrating The Printer
For printers not using smart labels, an Auto Calibrate should be sufficient to
properly calibrate the printer (see next section).
To calibrate printers that are using smart labels:
1. Run an Auto Calibrate to set up initial values (page 21).
2. Make a Media Profile printout.
3. Make any necessary adjustments to Threshold Range in the CALIBRATE
CTRL menu.
4. Run an Auto Calibrate again (page 21).
5. Make a Media Profile printout again to verify the Threshold Range you
selected in step 3 is correct.
6. Save the configuration, and then set the saved configuration as the
Power-Up configuration (page 37).
20
Running Auto Calibrate
Running Auto Calibrate
IMPORTANT
Since manufacturing differences in media and ribbon can decrease the
printer’s TOF (top-of-form) sensing reliability, you must run an Auto
Calibrate to provide optimum sensor threshold values for the installed
media and ribbon.
1. Set the printer power switch to | (On).
2. Press the
..
key to enter the QUICK SETUP menu.
NOTE: For a complete description of the QUICK SETUP menu, see page 30.
3. Press ↓ and ↵ together until ENTER SWITCH / UNLOCKED displays.
4. Press ↑ or ↓ until Label Length / 6 inch* displays (default).
5. Press + or – until the value that matches the physical length of the
installed media displays.
NOTE: Selecting the correct Label Length forces Auto Calibrate to increase
media advancement for long labels (to detect actual gaps, notches, or
marks) and decrease media advancement for short labels.
6. Press ↑ or ↓ until Gap/Mark Sensor / Disable* displays.
7. Press + or – until Gap displays.
NOTE: If you are using smart labels, see “Gap Sensing for Smart Labels” on
page 36.
8. Press ↵. An asterisk (*) displays next to the selected item.
9. Press ↓ until Auto Calibrate / Run Calibrate displays.
10. Press ↵. Media advances until it can accurately detect the label length
indicators and then stops at the top-of-form position. The Sensed
Distance value then displays for one second.
11. Auto Calibrate is successful when the Sensed Distance value correctly
matches that of the installed media. For Gap sensing, the Sensed
Distance value is the physical length of one label plus the length of one
gap.
12. If GAP NOT DETECTED or PAPER OUT displays:
a. Check the horizontal position of the media sensors.
b. Make a Media Profile printout to verify that the sensors are
performing properly.
c.
Press PAUSE and run Auto Calibrate again.
13. Press the PAUSE key to take the printer offline.
14. Press the FEED key several times. Each time you press FEED, the media
should advance one label length and stop.
15. Once the Sensed Distance value and performance is confirmed, save it to
the desired configuration menu as described on page 37 before powering
off the printer.

Pneumatic Control Valves And Gauges
Pneumatic Control Valves And Gauges
Air Cylinder Regulator
NOTE: You may also adjust the cylinder delay time through the Applicator
Delay menu. See “Applicator Delay Menu” on page 29.
The air cylinder regulator (CYLINDER valve) is used to regulate the air to the
applicator cylinder. The regulator setting affects how quickly the applicator
pad will extend (apply stroke) and return (return stroke) during the apply
cycle. This adjustment determines the force with which the applicator pad will
contact the product. If set too high, the applicator pad could contact the
product with enough force to cause damage. If set too low, the applicator pad
may not contact the product. The air pressure delivered for the apply stroke
and the return stroke is equal.
Monitor the setting of the air cylinder regulator using the PRESSURE gauge.
Air Jet Adjustment
The air jet adjustment (AIR JET) controls the air supply to the air jet tube. Air
is forced out the air jet tube allowing the labels to properly transfer over the
peel bar then to the applicator pad. If the adjustment is too low, the labels will
not properly transfer from the printer to the applicator pad. If set too high, the
label edge will be incorrectly positioned. The air jet is factory preset. Adjust
the air jet pressure by turning the AIR JET control clockwise to increase the
flow, counterclockwise to decrease the flow. See “Positioning The Air Jets” on
page 19.
Vacuum Adjustment
NOTE: You may also adjust the vacuum delay time through the Applicator
Delay Menu. See “Applicator Delay Menu” on page 29.
The vacuum adjustment (VACUUM) controls the amount of air flow through
the vacuum generator, thus determining the amount of vacuum holding the
label onto the applicator pad. A weak vacuum will cause labels to fall off of the
applicator pad prematurely. A vacuum that is too strong, however, can cause
difficulty when transferring the label onto the applicator pad and the product.
Vacuum is increased by rotating the valve clockwise and decreased by
rotating the valve counterclockwise.
NOTE: To get a vacuum on every label, every hole on the applicator pad
must be covered by the label surface.
Monitor the setting of the vacuum adjustment using the VACUUM gauge.

QUICK SETUP Menu Items
Print Intensity
This menu item specifies the level of thermal energy from the printhead to be
used for the type of media and ribbon installed.
Large numbers imply more heat (thermal energy) to be applied for each dot.
This has a significant effect on print quality. The print intensity and speed
must match the media and ribbon type to obtain the best possible print quality
and barcode grades.
The range is –15 through +15. The default is –3.
Print Speed
This menu item specifies the speed in inches per second (ips) at which the
media passes through the printer while printing.
The range is 2 through 10 ips (in increments of 1 ips).
The default is 6 ips.
NOTE: The maximum print speed varies based on maximum printer width
and dot per inch (dpi) resolution of the printhead installed (203 or 300
dpi).

Direct. Indicates direct thermal printing (no ribbon) and requires special
heat sensitive media.
The default is Transfer, unless your printer is shipped as direct thermal only
(no ribbon motors installed).
NOTE: The Print Mode menu item does not appear for direct thermal only
printers.
Media Handling
This menu item specifies how the printer will handle the media (labels or tag
stock).
•
Tear-Off Strip. Printer prints on the media and sends it out the front until
the print buffer is empty, then positions the last label over the tear bar for
removal.
•
Tear-Off. After each label is printed, the printer positions the label over
the tear bar and waits for you to tear off the label before printing the next
one (on-demand printing). A “Remove Label” message displays to remind
you to remove the label before the next one can be printed.
•
Peel-Off. When the optional rewinder is installed, prints and peels die cut
labels from the liner without assistance. The printer waits for you to
remove the label before printing the next one (on-demand printing). The
label liner is rewound on the internal rewinder. A “Remove Label”
message displays to remind you to remove the label before the next one
can be printed.
•
Cut. When the optional media cutter is installed, it automatically cuts
media after each label is printed or can cut after a specified number of
labels have been printed using a software cut command. It cuts
continuous roll paper, labels, or tag stock.
NOTE: The Cut option is hidden when RFID Reader is set to Enable in the
RFID CONTROL menu.
•
Continuous. Printer prints on the media and sends it out the front.
The default is Tear-Off Strip.
Paper Feed Shift
This menu item represents the distance to advance a label (+ shift) or pull
back (– shift) when the Tear-Off Strip, Tear-Off, Peel-Off, or Cut Media
Handling option is enabled. The allowable range is –0.50 inches to the current

Label Length
In most applications, the user-selected Label Length will match the physical
label length. Physical label length is the actual label length of the media
installed. Following is a list of different media types:
•
Die cut labels: measurable length of the removable label (leading
edge to trailing edge). This does not include the liner material or gap.
•
Tag stock with notches or holes: measurable length from the trailing
edge of one notch or hole to the trailing edge of the next notch or
hole.
•
Tag stock with black marks on the underside: measurable length from
the leading edge of one black mark to the leading edge of the next
black mark.
•
Continuous media (no label length indicators): measurable length
should be within + 1 to 2% of the Label Length value entered.
Label Width
This menu item specifies the label width. The allowable range in inches is
00.1 to the maximum print width of the printer. The allowable range in
millimeters is 2.5 to the maximum width of the printer.

die cut labels or when using tag stock with notches or holes as label
length indicators on white background media. The
top-of-form position is the leading edge of the die cut label (trailing edge
of the gap, notch, or hole).
•
Advanced Gap. Select when using media that has liner gaps between
die cut labels with black background. The top-of-form position is the
leading edge of the die cut label (trailing edge of the gap, notch, or hole).
•
Advanced Notch. Select when using media with notches or holes that
interrupt a black vertical line on the underside of the media. The top-ofform position is the leading edge of the die cut label (trailing edge of the
gap, notch, or hole).
The default is Disable.
Gap Sensing for Smart Labels
If your smart labels have a horizontal black bar located within each liner gap,
set Gap/Mark Sensor to Gap. When you examine a Media Profile printout,
you will see that the black bar provides a much higher amplitude pulse than
that of any antenna, which will provide excellent top-of-form reliability.
If your smart labels have no horizontal black bar located within each liner gap,
you must choose between Gap and Advanced Gap sensing. Run an Auto
Calibrate (page 21), then make a Media Profile printout. Choose the sensing
type that provides the highest liner gap amplitude compared to the amplitude
of the antenna line. If you select Gap sensing, and then see that the Media
Profile printout shows very little amplitude difference for the liner gap
compared to the amplitude of the antenna line, select Advanced Gap sensing
instead.
Advanced Gap sensing (often called transmissive) uses an LED array for the
upper sensor and a receiver in the lower sensor to detect infrared light
through the liner gap. This sensing has the advantage of detecting the liner
gap as a positive amplitude pulse and the antenna line as a smaller, negative
pulse.
Save Config.
Allows you to save up to eight unique configurations to meet different print job
requirements. This eliminates the need to change the parameter settings for
each new job. The configurations are stored in memory and will not be lost if

WARNING
Printronix has provided the necessary guards and warnings within the
confines of the SLPA, but cannot anticipate each customer’s individual
installation and operational environments. It is the customer’s
responsibility to provide in-house safety guards to provide adequate
worker safety for their respective production settings.
WARNING
An input signal from the product sensor will activate the SLPA when the
SLPA is online unless it is taken offline.
This section provides a brief overview of the print and apply process as well
as suggested steps preliminary to printing.
During power-up, the SLPA performs a self-diagnostic test and indicates if the
system has any existing fault or warning conditions.
Once the SLPA is online and configured (if necessary) for the desired
application, take the SLPA offline before downloading labels from the host
into the buffer. This will prevent any chance of having the system cycle before
you are prepared to begin print operations.
For information on the proper setup of the SLPA, see “Setup Procedures” on
page 7.
Label Application (Positioning) Adjustments
To apply the labels at the desired location on the product:
1. Mount the product sensor on the side of the conveyor, determining if the
sensor should be mounted upstream from the applicator pad (product
passes sensor before pad) or downstream from the applicator pad
(product passes pad before sensor), depending on the application.
IMPORTANT
Mount the product sensor as close as possible to the applicator pad. If
the spacing between the two is too wide, it may be to difficult to set the
product sensor delay to position the label properly.
It is easier to position the label onto the product using the sensor delay
when the sensor is mounted upstream from the applicator pad.

Valve
Figure 14. Return Speed Control Valve
2. Use the flow control valve (located on the air cylinder) to adjust the speed
of the return stroke. (Figure 14.) Increase the speed by rotating the valve
counterclockwise and decrease the speed by rotating the valve
clockwise.
3. Set the Cycle Delay time for the product sensor using the Applicator
Delay menu. (See “Applicator Delay Menu” on page 95.)
NOTE: The Cycle Delay setting determines the amount of delay from the
time that the product sensor detects the product to the time that the
applicator pad is online. Since the label prints first, be sure to account
for printing time. The longer the time entered, the farther back (closer
to the trailing edge) the label will be placed onto the product.
Conversely, if this value is set to zero, for example, the applicator pad
will launch as soon as the label is printed.
Begin by setting the Cylinder Extend time to 100 msec to begin this
adjustment procedure. (See “Applicator Delay Menu” on page 95.)
40
Adjusting The Cylinder Extend Time
4. Place the product sample on the conveyor and allow it move past the
SLPA. The label that is applied will be used as a reference point for
positioning the rest of the labels.
5. To move the label toward the leading edge of the product, decrease the
Cycle Delay time. Begin by decreasing the time in intervals of 10 msec,
then fine tune in intervals 1 msec. Repeat this procedure until the label is
positioned where desired.
6. To move the label toward the trailing edge of the product, increase the
Cycle Delay time. Begin by increasing the time in intervals of 10 msec,
then fine tune in intervals 1 msec. Repeat this procedure until the label is
positioned where desired.
If the label still cannot be positioned properly, remount the product sensor as
follows:
1. To position the label toward the leading edge of the product, move the
product sensor upstream.
2. To position the label toward the trailing edge of the product, move the
product sensor downstream.
3. Once the label is positioned in the desired location on the product, secure
the product sensor onto the conveyor.
If the SLPA cycles when a product is not in position, a background object may
be activating the sensor. To correct this problem, reposition the product
sensor or adjust the product sensor. See “Product Sensor” on page 197 for
more information on product sensor adjustments.
WARNING
Interrupting the signal on the product sensor will activate the SLPA.
Make certain that the path of the applicator path is clear.
Adjusting The Cylinder Extend Time
NOTE: Remember that the supply air pressure to the SLPA should be
80 to 100 psi (550 to 690 kPa).
1. Set the Cylinder Extend time using the Applicator Delay menu.
(“Applicator Delay Menu” on page 29.)
NOTE: The amount of time the applicator pad is energized through the
cylinder extend time, determines how far the pad travels during
application of the label. The longer the time entered, the farther the
distance the applicator pad travels. If this value is set to zero, for
example, the applicator pad will not launch.
Set the Cylinder Extend time to 110 msec to begin this adjustment
procedure.
•
If the applicator pad does not contact the product (if the stroke time is not
long enough):
Increase the Cylinder Extend time using the Applicator Delay menu.
Begin by increasing the time in intervals of 6 msec, then fine tune in
increments of 1 msec. A higher setting allows the applicator pad more
time to extend toward the product, therefore, increasing the stroke
length.
41
Chapter
Printing And Applying Labels
•
If the applicator pad remains on the product for too long (if the stroke time
is too long):
Decrease the Cylinder Extend time using the Applicator Delay menu.
Begin by increasing the time in intervals of 6 msec, then fine tune in
increments of 1 msec. A lower setting decreases the amount of time
that the applicator pad is extended (in contact with the product).
The Print And Apply Process
Before labels can be printed and applied:
1. Ensure that the protective guards are properly secured and that materials
are clear of the applicator pad and printhead assembly.
2. Ensure that you have input time values for Cycle Delay, Cylinder Extend,
and Vacuum Delay (if applicable). (See “Applicator Delay Menu” on
page 95.)
NOTE: The applicator will not move unless a value is entered for Cylinder
Extend.
3. Press the Pause key on the control panel to enable the product sensor, or
to allow remote signals received through the interface package option to
activate the SLPA.
NOTE: You may wish to cycle several labels onto product samples, to ensure
proper operation of the SLPA.

Printhead Cleaning
As you use your SLPA, the printhead may become dirty which can result in
poor print quality. Clean the printhead each time you install new ribbon
(thermal transfer print mode) or install new media (direct thermal print mode).
Clean the printhead with the cleaning pen supplied with the SLPA or with a
cotton swab moistened with alcohol.
By keeping your printhead clean, you will help maintain its life.
Platen Rollers Cleaning
Media dust and adhesive residue on the platen roller can degrade print quality
and cause voids in your label image. Clean the platen rollers at the same time
as the printhead. See Figure 15 on page 44.
Use a small amount of isopropyl alcohol on a cloth to clean the platen roller.
With the pivoting deck up the platen roller can be rotated forward by hand to
access and clean its entire surface area.
Media Sensor Cleaning
The Upper and Lower Media Sensors should be cleaned to ensure reliable
TOF and paper out sensing. Clean the media sensors at the same time as the
printhead.
The Upper Media Sensor (located in the horizontal slot of the printhead cover)
can be wiped clean using a soft cloth. The Lower Media Sensor, easily seen
by its visible red light, is located in the horizontal slot of the media guard.
Remove media dust by vacuuming or blowing air across the lens cover.
Cleaning Procedure
1. Set the power switch to O (Off) and let the SLPA cool for 5 minutes.
2. Rotate the deck lock lever clockwise to open the pivoting deck and
remove any media and ribbon (if loaded) to gain access to the printhead
assembly heating element area.
3. Gently rub the felt tip of the cleaning pen or a cotton swab moistened with
isopropyl alcohol across the printhead heating elements (light brown
area).
4. Allow the printhead to dry for one minute before reloading the media and
ribbon.
5. Clean the platen roller.
6. Clean the upper and lower media sensors.
CAUTION
Do not use sharp objects on the print surface of the printhead. Be aware
that the edges of the printhead may be sharp. Keep fingers away from
the edges.

Figure 16. The Applicator Pad Assembly
The applicator pad must be clean to ensure that labels will properly dispense.
Use isopropyl alcohol and a clean soft cloth. No other cleaning agent should
be used to clean the applicator pad.
Perform a maintenance check of the applicator pad vacuum chamber
approximately every three months, at minimum, using the following
procedures:
1. Remove the four (or six) hex screws found at the top of the applicator
pad, allowing the bottom pad to drop downward.
2. Check the holes of the applicator pad to make certain that there are no
large particles of dirt or dust clogging any of the holes.
3. Reassemble, making certain that the gasket (foam tape) is seated
properly before replacing the bottom pad.
4. Check for leaks by covering all the holes in the applicator pad with a piece
of paper. If there is a leak, the vacuum will not retain the paper on
underside of the applicator. Sealing compound may be used to isolate
leaks, but must dry thoroughly before the applicator may be used.
46
Cleaning/Replacing The Vacuum Generator
Cleaning/Replacing The Vacuum Generator
Air flow through the vacuum generator creates the vacuum for the applicator
pad, allowing the label to be held in place. If the label is not retained on the
pad and the pad has already been inspected for leaks, then the vacuum
generator should be cleaned as follows.
1. Locate the vacuum generator inside the electrical enclosure, on the
applicator side of the SLPA (see Figure 17). The vacuum generator
housing will mark the pressure connection with a P and the vacuum
connection with a V. Label the respective tubes before disconnecting
them, to ensure proper reassembly.

Calibrating The Media Sensors
Calibrating The Media Sensors
Due to manufacturing differences in media and ribbon, the media sensors
may have difficulty differentiating between the label and the liner or the label
and the black mark. When this occurs, the SLPA may intermittently skip a
label or display a fault message such as GAP NOT DETECTED / See Manual
or PAPER OUT / Load Paper.
Media sensor sensitivity and reliability can be improved by changing the
Gap/Mark Threshold and/or Paper Out Threshold values. You can change
these values automatically by performing the Auto Calibrate or Manual
Calibrate procedure in the CALIBRATE CTRL menu or change them manually
by entering your own Gap/Mark Threshold or Paper Out Threshold values.
(The changes take effect immediately within the current configuration menu.)
Auto or Manual Calibrate is completed successfully when the displayed
Sensed Distance value correctly matches that of the installed media. When
Gap is selected, the Sensed Distance value should match the length from the
trailing edge of one gap to the trailing edge of the next gap (or one label + one
gap). When Mark is selected, the Sensed Distance value should match the
length from the leading edge of one black mark to the leading edge of the next
black mark.
When you have completed Auto or Manual Calibrate, you can verify that the
new values are correct by pressing the Feed key several times. Each time you
press Feed, media advances one label and stops at the correct Top-of-Form
position of the next label.
Once you confirm the correct values, save them to the desired configuration
menu before powering off the SLPA. See “Saving A Configuration” on
page 67.
Running Auto Calibrate
You can initialize Auto Calibrate via the Apply key (described in detail below)
or via the CALIBRATE CTRL or DIAGNOSTIC menus in Menu mode.
NOTE: Verify that the Gap/Mark Sensor option (Disable, Mark, Gap,
Advanced Gap, or Advanced Notch) matches the installed media.
See “Sensing Different Media Types” on page 52.
Check that the media sensors are horizontally positioned to permit
sensing of the label length indicators. See “Positioning The Media
Sensors” on page 50.
If you try to do an Auto Calibrate when Peel-Off Media Handling is
enabled, the LCD will display CANNOT CALIBRATE / Disable PeelOff. Before you can do an Auto Calibrate, you must select another
media handling mode.
1. Press the Pause key until OFFLINE displays on the LCD.
2. Press ↓ and ↵ together until ENTER SWITCH UNLOCKED displays.
3. Press the Apply key until Printer Tests / Auto Calibrate displays.
4. Press ↵. Media advances until it can accurately detect the label length
indicators and then stops at the Top-of-Form position. The Sensed
Distance value will then display for one second.
57
Chapter
System Adjustments
5. Auto Calibrate is successful when the Sensed Distance value correctly
matches that of the installed media:
•
Gap/Mark Sensor = Gap, Advanced Gap, or Advanced Notch:
The Sensed Distance value is the physical length of one label plus
the length of one gap, notch, or hole.
•
Gap/Mark Sensor = Mark: The Sensed Distance value is the
physical distance from the leading edge of one black mark to the
leading edge of the next.
•
Gap/Mark Sensor = Disable: Not applicable. If Gap/Mark Sensor is
set to Disable, the Sensed Distance value will not be updated.
If GAP NOT DETECTED displays, run Auto Calibrate again.
If Auto Calibrate continues to end with an incorrect Sensed Distance
value displayed or a fault message displayed, run Manual Calibrate as
described on page 58.
NOTE: The amount of media sampled during Auto Calibrate is based on the
length of a label and transitions detected, without error, between a
label and its label length indicators.
6. Press the Pause key until OFFLINE displays.
7. Press the Feed key several times. Each time you press Feed, the media
advances one label length and stops.
NOTE: After a form feed, the position of the leading edge of the next label
depends on the type of Media Handling mode selected under the
QUICK SETUP menu. Tear-Off and Tear-Off Strip Media Handling
will position the label edge at the peel bar, while Continuous will
position the label edge under the printhead.
8. Press the Pause key until ONLINE displays.
9. Once the Sensed Distance value is confirmed, save it to the desired
configuration (page 67) before powering off the SLPA.
Running Manual Calibrate
Manual Calibrate should be performed only when the values derived from
Auto Calibrate fail to improve the media sensors’ ability to sense label length
indicators on the installed media. You must first enable Admin User in the
PRINTER CONTROL menu before accessing or initializing Manual Calibrate
in the CALIBRATE CTRL menu.
NOTE: Verify the Gap/Mark Sensor option (Gap, Mark, Advanced Gap,
Advanced Notch, or Disable) matches the installed media. See
“Sensing Different Media Types” on page 52.
Ensure the media sensors are horizontally positioned to permit
sensing of the label length indicators. See “Positioning The Media
Sensors” on page 50.
Ensure the Print Mode option selected in the QUICK SETUP menu
matches the media installed. Select Direct for heat sensitive media
(no ribbon required) or Transfer for thermal transfer media (ribbon
required).

Calibrating The Media Sensors
If you try to do a Manual Calibrate when Peel-Off Media Handling is
enabled, the LCD will display, CANNOT CALIBRATE / Disable PeelOff. Before you can do a Manual Calibrate, you must select another
media handling mode.
1. Press the Menu key to take the SLPA offline and into Menu mode.
2. Press the ↓ and ↵ keys together until ENTER SWITCH UNLOCKED
displays.
3. Press the Menu key until PRINTER CONTROL displays.
4. Press ↑ until Admin User displays.
5. Press + until Enable displays.
6. Press ↵ to select Enable. An asterisk (*) appears next to Enable.
7. Press the Menu key until CALIBRATE CTRL displays.
8. Press ↓ until Manual Calibrate / Run Calibrate displays, then press ↵.
9. Follow the instructions displayed on the LCD. Example: REMOVE
RBN&MEDIA / Press Enter indicates that you must open the pivoting
deck and remove the ribbon and media from under the printhead, close
and lock the pivoting deck, and press the ↵ key.
During the last step of Manual Calibrate, the SLPA will advance the media
and attempt to detect the label length indicators and stop at the Top-ofForm position. The Sensed Distance value will then display for one
second. The calibrate is successful when the Sensed Distance value
correctly matches that of the installed media.
If CALIBRATION FAIL / See Manual displays, run Manual Calibrate
again.
NOTE: The amount of media sampled during Manual Calibrate is based on
the length of a label and the transitions detected without error,
between a label and its label length indicators.
10. Press the Pause key until OFFLINE displays.
11. Press the Feed key several times. Each time you press Feed, the media
advances one label length and stops.
NOTE: After a form feed, the position of the leading edge of the next label
depends on the type of Media Handling mode selected under the
QUICK SETUP menu. Tear-Off and Tear-Off Strip Media Handling
positions the label edge at the peel bar, while Continuous positions
the label edge under the printhead.
12. Once the correct values are confirmed, save them to the desired
configuration (page 37) before powering off the SLPA.
