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
1. Make sure the media is properly loaded and the top cover of the printer
is closed. Then, turn the printer power on if you have not already done
so.
2. When the status light is solid green, press and hold the feed button until
the status light flashes once.
3. Release the feed button. A configuration label will print.
If you cannot get this label to print, refer to Troubleshooting.
Hooking Up the Printer and Computer
This printer comes with a bidirectional parallel data interface. You must
supply the required interface cable for your application.
CAUTIONS:Keep the power switch in the OFF position when
attaching the interface cable.
The power supply barrel connector must be inserted
into the power supply receptacle on the back of the
printer before connecting or disconnecting the communications cables.
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.
Parallel Interface Requirements
The required cable (IEEE 1284-compliant is recommended) must have a
standard 36-pin parallel connector on one end, which is plugged into the
parallel port located on the back of the printer. The other end of the parallel
interface cable connects to the printer connector at the host computer.
For pinout information, refer to page .
Interface Cable Requirements
Data cables must be of fully shielded construction and fitted with metal or
metalized connector shells. Shielded cables and connectors are required to
prevent radiation and reception of electrical noise.
To minimize electrical noise pickup in the cable:
Keep data cables as short as possible (6’ [1.83 m] recommended).
Do not tightly bundle the data cables with power cords.
Do not tie the data cables to power wire conduits.
Communicating with the Printer
When using the parallel port, typically there is no setup is required once the
cable is plugged in. If you should encounter any problems, consult the
user’s guide that came with your computer.
Adjusting the Print Width
Print width must be calibrated when:
■
You are using the printer for the first time.
■
There is a change in the width of the media.
Print width may be set by way of the five-flash sequence in “Feed Button
Modes” (see page ) or refer to the Print Width (^PW) command (consult
your ZPL II Programming Guide).
Adjusting the Print Darkness
The relative darkness setting is controlled by either the six-flash sequence in
“Feed Button Modes” (see page ) or the Set Darkness (~SD) ZPL II
command (follow the instructions in the ZPL II Programming Guide).
Adjusting the Print Speed
Print quality is affected by print speed and the media you are using. Only
by experimenting will you find the optimal mix for your application.
If you find that the print speed needs to be adjusted, refer to the Print Rate
(^PR) command in the ZPL II Programming Guide.
Operation & Options
This section helps you get the most from your printer.
You must use programming to control many of the printer’s functions. For
example, the ~JL command controls label length. For detailed information
about creating labels using ZPL II, refer to the ZPL II Programming Guide
or visit our web site at www.zebra.com.
To improve print quality, changing both print speed and density may be
required to achieve the desired results. Your application’s printer driver
provides control of the speed and heat (density).
Thermal Printing
The print head becomes hot while printing. To protect from damaging the
print head and risk of personal injury, avoid touching the print head. Use
only the cleaning pen to perform maintenance.
The discharge of electrostatic energy that accumulates on the surface of the
human body or other surfaces can damage or destroy the print head or
electronic components used in this device. You must observe static-safe
procedures when working with the print head or the electronic components
under the top cover.
You must use the correct media for the type of printing you require. When
printing without a ribbon, you must use direct thermal media. When using
ribbon, you must use thermal transfer media. The printer’s ribbon sensor
detects motion of the supply spindle.
Replacing Supplies
If labels or ribbon run out while printing, leave the printer power on while
reloading (data loss results if you turn off the printer). The printer
automatically restarts after you load a new label or ribbon roll.
Always use high quality, approved labels, tags and ribbons. If adhesive
backed labels are used that don’t lay flat on the backing liner, the exposed
edges may stick to the label guides and rollers inside the printer, causing the
label to peel off from the liner and jam the printer. Permanent damage to the
print head may result if a non-approved ribbon is used as it may be wound
incorrectly for the printer or contain chemicals corrosive to the print head.
Approved supplies can be ordered from your dealer.
Adding a New Transfer Ribbon
If ribbon runs out in the middle of a print job, the indicator lights orange
and the printer waits for you to add a fresh roll.
1. Keep the power on as you change ribbon.
2. Open the top cover, then cut the used ribbon so you can remove the
cores.
3. Load a new ribbon roll. Refer to page for this procedure.
4. Close the top cover.
5. Press the Feed button to restart printing.
Replacing a Partially Used Transfer Ribbon
To remove used transfer ribbon, perform the following steps.
1. Cut the ribbon from the take-up roll.
2. Remove the take-up roll and discard used ribbon.
3. Remove the supply roll and tape the end of any fresh ribbon to prevent
it from unwrapping.
When reinstalling a partially used supply roll, tape the cut end onto the
empty take-up roll.
Printing in Peel-Mode
ON
OFF
The optional dispenser allows you to print
in “peel-mode” where the label backing
follows a different path and the labels are
presented one at a time for subsequent
placement.
1. Remove several labels from the
backing material.
2. Open the top cover.
3. Open the dispenser door.
4. Switch on the label-taken sensor.
5. Insert the backing in front of the peel
bar and behind the peel roller.
6. Close the dispenser door.
7. Close the top cover.
8. Press the Feed button to advance the
label.
During the print job, the printer will peel
off the backing and present a single label.
Take the label from the printer so it will
print the next label.
Printing on Fan-Fold Media
Printing on fan-fold media requires you to
set both the media hangers and the media
guides in position.
Lock-down
Screw
1. Open the top cover.
2. With a sample of your media, adjust
the media hangers to the width of the
media. The hangers should just touch,
but not restrict, the edges of the
media.
3. Tighten the screw using a small
Phillips driver #1.
4. With a sample of your media, adjust
the guides to the width of the media.
The guides should just touch, but not
restrict, the edges of the media.
5. Insert the media through the slot at the
rear of the printer.
6. Run the media between the hangers
and guides.
7. Close the top cover.
RFID Guidelines
RFID is an abbreviation for radio frequency identification. To use the
RFID capabilities of this printer, you will need the appropriate media which
have incorporated into them a transponder.
These RFID transponders have coils built into them. You can write data to
(encode) and read data from the transponder’s memory, and obtain certain
information regarding the status of the RFID subsystem. This printer has an
antenna that encodes the transponder within the media. When a transponder
lines up over the antenna, you are able to communicate to it to get
information and write to the transponder.
Following your Zebra Programming Language (ZPL) commands, the
printer first transfers data to the RFID transponder in the media, then prints
bar code and human-readable data on the media.
Each transponder has blocks that are written and read through ZPL
commands. The ZPL commands allow you to adjust the number of retries
to get a successful execution of the command. If a block cannot be written
within the number of retries, then the media is fed out with a VOID type
error message.
After the printer feeds the failed media, the printer attempts to write to
another transponder in the next label, tag, or ticket. The rewriting follows
the same series of commands, and the same number of retries for each
block. If the printer fails to program this transponder, then the printer also
feeds this media with a VOID message. The printer attempts one final
attempt time to write (encode), and if unsuccessful, prints a third VOID
media.
No customer format information appears on media that fails to be written.
After three VOID feeds, the printer removes the customer format from the
print queue, and proceeds with the next format (if one exists in the buffer).
Supported Transponders
The R402 supports several transponder types:
■
Tag-it
■
I•Code
■
Picotag 2K
■
ISO 15693
Tag-it Transponders
Tag-it labels are high frequency (13.56MHz) devices. Tag-it is a read/write
RFID transponder with 256 bits of storage capacity for user data. Data is
addressed in eight blocks of 32 bits, each block containing four bytes.

I Code Transponders
I-Code transponders are high frequency (13.56MHz) devices but have 512
bits of storage capacity. Data is addressed in sixteen blocks of 32 bits, each
block containing four bytes. The first two blocks of data (block 0 and 1) are
used for storage of a unique 64 bit serial number. The next two blocks
(blocks 2 and 3) are used for storage of configuration information; block 4
is used for family or application identification and blocks 5 to 15 are free
for user application use.
If you are using I-Code transponders for your own use, and don’t require
universal special function or family codes, then you can program blocks 3
through 15.

ZPL II Commands for RFID
^WT – Write Tag
The format for the ^WT instruction is: ^WTb,r,m,w,s
where
^WT = Write Tag command
b = Block Number
Default value: 0
Other values: 1 to n, where n is the maximum number of
blocks for the tag
This is the starting block number. If the user sends more than a block of
data it will overflow into the next block. If the user overflows the block and
subsequent blocks cause errors (write protects, beyond range, etc.), the
write will be aborted, but blocks already written will not revert to original
contents. It’s up to the caller to ensure blocks aren’t accidentally
overwritten.
r = Retries
Default value: 0
Other values: 1 to 10, number of retries
m = motion
Default value: 0 (Feed label after writing)
Other value: 1 (No Feed after writing, other ZPL may cause
a feed)
w = Write protect
Default value: 0 (NOT write protected)
Other value: 1 (Write protect)
s = Special mode
Reserved
^RT – Read Tag
The format for the ^RT instruction is: ^RT#,b,n,f,r,m,s
where
^RT = Read Tag command
# = Number to be assigned to the Field
Default value: 0
Other Values: 1 to 9999
b = Starting Block Number
Default value: 0
Other values: 1 to n, where n is the maximum number of
blocks for the tag
n = Number of blocks to read
Default value: 1
Other values: 2 to n, where n is maximum number of blocks
minus starting block number. In other words, if the tag has 8
blocks (starting with block 0) and you’re starting with block 6,
n can be 2. This would give you block 6 and block 7
information.
f = Format
Default value: 0 ASCII
Other values: 1 Hexadecimal
r = Retries
Default value: 0
Other values: 1 to 10, number of retries
m = motion
Default value: 0 (Feed label after writing)
Other value: 1 (No Feed after writing, other ZPL may cause
a feed)
s = Special Mode
Default value: 0
Other values: 1 to 255, to specify more detailed mode control.
^RT – Read Tag (continued)
Example: This reads a block from a tag, and prints it on a label:
^XA
^FO20,120^A0N,60^FN1^FS
^FO20,100^A0N,20^FN2^FS
^RT1,0,7,3,0,5,0,0^FS
^RT2,0,2,2,0,5,0,0^FS
^XZ
The first ^RT command automatically detects the tag type, starting at block
7, reads three blocks of data in ASCII format. It will retry the command 5
times if necessary. A “void” label will be generated if the read is
unsuccessful after ‘r’ retries. The data read will go into the ^FN1 location
of the recalled format.
The second ^RT command automatically detects the tag type, string at
block 2, reads two blocks of data in ASCII format. It retries up to 5 times.
The data read will go into the ^FN2 location of the recalled format.
The data can be sent back to the host via the ^HV command.
^RS – RFID Setup
The format for the ^RS instruction is: ^RSt
where
t = tag type
Default value: 0 –NONE (No tags available)
Other values:
1- Auto detect (automatically determine the
tag type, by querying the tag)
2- Tag-it (Texas Instruments Tag-it tags)
3- I •Code (Philips I·Code tags)
^RI – RFID Get Tag Unique ID
The format for the ^RI instruction is: ^RIn
where
n = field number to store the unique ID
The unique ID will be read from the tag and available to
print or return to the host computer.
Example: This reads a block from a tag, and prints it on a label:
^XA
^FO100,100^A0N, 60^FN0^FS
^RI0^FS
^XZ
Sample of RFID Programming
TM
ZPL II is Zebra Technologies Corporation’s Zebra Programming
Language II label design language. ZPL II lets you create a wide variety of
labels from the simple to the very complex, including text, bar codes, and
graphics.
This section is not intended as an introduction to ZPL II. If you are a new
ZPL II user, order a copy of the ZPL II Programming Guide (part# 46530L)
or go to the internet address http://support.zebra.com and select the
Documentation Button to download the guide.
For your programming, do the following:
1. Set up the printer and turn the power on.
2. Use any word processor or text editor capable of creating ASCII-only
files (ex: Microsoft Word® and save as a .txt file) and type in the label
format exactly as shown in the sample label format that follow.
3. Save the file in a directory for future use. Use the “.zpl” extension.
4. Copy the file to the printer.
From the DOS command window, use the “COPY” command to send a
file to the Zebra printer. For example, if your file name is format1.zpl
then type, “COPY FORMAT 1.ZPL XXXX”, where “XXXX” is the
port to which your Zebra printer is connected, for example, “COM1” or
“LPT1.”
5. Compare your results with those shown. If your printout does not look
like the one shown, confirm that the file you created is identical to the
format shown, then repeat the printing procedure. If nothing prints,
refer to the “Getting Started” section to make sure your system is set up
correctly, otherwise refer to the “Troubleshooting and Diagnostics”
section.

Aluminum and other metals within tag may interfere with read/write.
Make sure media meet requirements.
Increase the number of retries in the ZPL II commands.
Time out may have occurred during internal communication. Cycle
power and try printing label again.
Call a service technician if you have been unsuccessful in getting your
expected print out and data.
Manual Calibration
Manual calibration is recommended whenever you are using pre-printed
labels (or label backing) or if the printer will not correctly auto calibrate.
1. Turn on the printer power.
2. Remove approximately 4" (102 mm) of labels from a section of backing
material. Load the media so that only the backing material is threaded
through the printer and under the print Head.
3. Press and hold the feed button until the green status LED flashes once,
then twice. Release the feed button.
4. The printer will set the media sensor for the label backing being used.
After it is done making this adjustment, the roll will automatically feed
until a label is positioned at the print Head.
5. A profile of the media sensor settings (similar to the example below)
will print. Upon completion, the printer will save the new settings in
memory and the printer is ready for normal operation.
6. Press the feed button. One entire blank label will feed. If this does not
happen, try defaulting (refer to the four-flash sequence in “Feed Button
Modes” on page 50) and recalibrating the printer.
NOTE: Performing a manual calibration disables the auto calibration
function. To return to auto calibration, default the printer (see the
four-flash sequence in “Feed Button Modes” on page 50).
Troubleshooting Tests
Printing a Configuration Label
To print out a listing of the printer’s current configuration, refer to the
one-flash sequence in “Feed Button Modes” on page 50.
Recalibration
Recalibrate the printer if it starts to display unusual symptoms, such as
skipping labels. See “Auto Calibration” on page .
Resetting the Factory Default Values
Sometimes, resetting the printer to the factory defaults solves some of the
problems. Follow the four-flash sequence instructions in “Feed Button
Modes” on page 50.
Communications Diagnostics
If there is a problem transferring data between the computer and printer, try
putting the printer in the communications diagnostics mode. The printer
will print the ASCII characters and their respective hexadecimal values (a
sample is shown in Figure 23) for any data received from the host
computer. To find out how, refer to the power off mode procedure in “Feed
Button Modes” on page 50.
Feed Button Modes
Power Off Mode (Communications Diagnostics Mode)
With the printer power off, press and hold the feed button while you turn on the power. The printer
prints out a listing of its current configuration (see Figure 22). After printing the label, the printer will
automatically enter a diagnostic mode in which the printer prints out a literal representation (see Figure
23) of all data subsequently received. To exit the diagnostic mode and resume printing, turn off and then
turn on the printer.
Power On Modes
With the printer power on and top cover closed, press and hold the feed button for several seconds. The
green status LED will flash a number of times in sequence. The explanation at the right (Action) shows
what happens when you release the key after the specific number of flashes.

To reset the communication parameters: Press and release the feed button while
the LED rapidly flashes yellow and green. The serial communication parameters
reset to 9600 baud, 8 bits per character, no parity, 1 stop bit, and XON/XOFF.
For autobaud synchronization: Send a ZPL II format to the printer while the LED
rapidly flashes yellow and green. When the printer and host are synchronized, the
LED changes to solid green. NOTE: No labels will print during autobaud
synchronization.

The print width calibrates. While the status LED alternately flashes green and
yellow, a series of stacking rectangles print on the label. When the rectangle prints
to the outer edges of the label, press and release the feed button. The label width
and current communication parameters will be saved into memory.

The print darkness calibrates. A series of nine samples print, starting with the
lightest and ending with the darkest image. When the desired print darkness is
achieved, press and release the feed button. The print darkness will be saved into
memory.
If the feed button remains pressed after a 7-flash sequence, the printer will ignore the button when it
is released.
