Operator ControlsPower SwitchPress up to turn ON or down to turn OFF the printer.CAUTION: The power should be turned off before connecting ordisconnecting the communications and power cables.Feed ButtonForces the printer to feed one blank label.Takes the printer out of a “pause” condition. (The printer is put into“pause” by either a ZPL II command or an error condition.) See “What theStatus Light is Telling You” on page .Used for printer setup and status (see “Feed Button Modes” on page ).Status LightFunctions as a printer operational indicator (see “What the Status Light isTelling You” on page ).
Printing a Test LabelBefore you connect the printer to your computer, make sure that the printeris in proper working order. You can do this by printing a configurationlabel1. Make sure the media is properly loaded and the top cover of the printeris closed. Then, turn the printer power on if you have not already doneso.2. When the status light is solid green, press and hold the feed button untilthe 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 ComputerThis printer comes with a bidirectional parallel data interface. You mustsupply the required interface cable for your application.CAUTIONS:Keep the power switch in the OFF position whenattaching the interface cable.The power supply barrel connector must be insertedinto the power supply receptacle on the back of theprinter before connecting or disconnecting the com-munications cables.This printer complies with FCC “Rules and Regula-tions,” Part 15, for Class B Equipment, using fullyshielded six-foot data cables. Use of longer cables orunshielded cables may increase radiated emissionsabove the Class B limits.Parallel Interface RequirementsThe required cable (IEEE 1284-compliant is recommended) must have astandard 36-pin parallel connector on one end, which is plugged into theparallel port located on the back of the printer. The other end of the parallelinterface cable connects to the printer connector at the host computer.For pinout information, refer to page .Interface Cable RequirementsData cables must be of fully shielded construction and fitted with metal ormetalized connector shells. Shielded cables and connectors are required toprevent 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 PrinterWhen using the parallel port, typically there is no setup is required once thecable is plugged in. If you should encounter any problems, consult theuser’s guide that came with your computer.Adjusting the Print WidthPrint 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 ButtonModes” (see page ) or refer to the Print Width (^PW) command (consultyour ZPL II Programming Guide).Adjusting the Print DarknessThe relative darkness setting is controlled by either the six-flash sequence in“Feed Button Modes” (see page ) or the Set Darkness (~SD) ZPL IIcommand (follow the instructions in the ZPL II Programming Guide).Adjusting the Print SpeedPrint quality is affected by print speed and the media you are using. Onlyby 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 & OptionsThis section helps you get the most from your printer.You must use programming to control many of the printer’s functions. Forexample, the ~JL command controls label length. For detailed informationabout creating labels using ZPL II, refer to the ZPL II Programming Guideor visit our web site at www.zebra.com.To improve print quality, changing both print speed and density may berequired to achieve the desired results. Your application’s printer driverprovides control of the speed and heat (density).Thermal PrintingThe print head becomes hot while printing. To protect from damaging theprint head and risk of personal injury, avoid touching the print head. Useonly the cleaning pen to perform maintenance.The discharge of electrostatic energy that accumulates on the surface of thehuman body or other surfaces can damage or destroy the print head orelectronic components used in this device. You must observe static-safeprocedures when working with the print head or the electronic componentsunder the top cover.You must use the correct media for the type of printing you require. Whenprinting without a ribbon, you must use direct thermal media. When usingribbon, you must use thermal transfer media. The printer’s ribbon sensordetects motion of the supply spindle.
Replacing SuppliesIf labels or ribbon run out while printing, leave the printer power on whilereloading (data loss results if you turn off the printer). The printerautomatically restarts after you load a new label or ribbon roll.Always use high quality, approved labels, tags and ribbons. If adhesivebacked labels are used that don’t lay flat on the backing liner, the exposededges may stick to the label guides and rollers inside the printer, causing thelabel to peel off from the liner and jam the printer. Permanent damage to theprint head may result if a non-approved ribbon is used as it may be woundincorrectly for the printer or contain chemicals corrosive to the print head.Approved supplies can be ordered from your dealer.Adding a New Transfer RibbonIf ribbon runs out in the middle of a print job, the indicator lights orangeand 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 thecores.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 RibbonTo 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 preventit from unwrapping.When reinstalling a partially used supply roll, tape the cut end onto theempty take-up roll.
Printing in Peel-ModeThe optional dispenser allows you to printin “peel-mode” where the label backingfollows a different path and the labels arepresented one at a time for subsequentplacement.1. Remove several labels from thebacking 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 peelbar and behind the peel roller.6. Close the dispenser door.7. Close the top cover.8. Press the Feed button to advance thelabel.During the print job, the printer will peeloff the backing and present a single label.Take the label from the printer so it willprint the next label.ON OFF
Printing on Fan-Fold MediaPrinting on fan-fold media requires you toset both the media hangers and the mediaguides in position.1. Open the top cover.2. With a sample of your media, adjustthe media hangers to the width of themedia. The hangers should just touch,but not restrict, the edges of themedia.3. Tighten the screw using a smallPhillips driver #1.4. With a sample of your media, adjustthe guides to the width of the media.The guides should just touch, but notrestrict, the edges of the media.5. Insert the media through the slot at therear of the printer.6. Run the media between the hangersand guides.7. Close the top cover.Lock-downScrew
RFID GuidelinesRFID is an abbreviation for radio frequency identification. To use theRFID capabilities of this printer, you will need the appropriate media whichhave 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 certaininformation regarding the status of the RFID subsystem. This printer has anantenna that encodes the transponder within the media. When a transponderlines up over the antenna, you are able to communicate to it to getinformation and write to the transponder.Following your Zebra Programming Language (ZPL) commands, theprinter first transfers data to the RFID transponder in the media, then printsbar code and human-readable data on the media.
Each transponder has blocks that are written and read through ZPLcommands. The ZPL commands allow you to adjust the number of retriesto get a successful execution of the command. If a block cannot be writtenwithin the number of retries, then the media is fed out with a VOID typeerror message.After the printer feeds the failed media, the printer attempts to write toanother transponder in the next label, tag, or ticket. The rewriting followsthe same series of commands, and the same number of retries for eachblock. If the printer fails to program this transponder, then the printer alsofeeds this media with a VOID message. The printer attempts one finalattempt time to write (encode), and if unsuccessful, prints a third VOIDmedia.No customer format information appears on media that fails to be written.After three VOID feeds, the printer removes the customer format from theprint queue, and proceeds with the next format (if one exists in the buffer).Supported TranspondersThe R402 supports several transponder types:■Tag-it■I•Code■Picotag 2K■ISO 15693
Tag-it TranspondersTag-it labels are high frequency (13.56MHz) devices. Tag-it is a read/writeRFID transponder with 256 bits of storage capacity for user data. Data isaddressed in eight blocks of 32 bits, each block containing four bytes.Tag-It BlocksBlock # Description Bytes0 User Data32 User1 User Data2 User Data3 User Data4 User Data5 User Data6 User Data7 User Data
I Code TranspondersI-Code transponders are high frequency (13.56MHz) devices but have 512bits of storage capacity. Data is addressed in sixteen blocks of 32 bits, eachblock containing four bytes. The first two blocks of data (block 0 and 1) areused 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 4is used for family or application identification and blocks 5 to 15 are freefor user application use.If you are using I-Code transponders for your own use, and don’t requireuniversal special function or family codes, then you can program blocks 3through 15.I-Code BlocksBlock # Description Bytes0 Serial Number (write protected)1 Serial Number (write protected)2 Write Protect Block (Caution*)3 Special Function Block 8 Optional4 Family Code5 User Data40 User6 User Data7 User Data8 User Data9 User Data10 User Data11 User Data12 User Data13 User Data14 User Data15 User Data* The bits in block 2 determine the write access conditions for itself andeach of the remaining blocks. You can leave blocks 2 through 15 open oryou can write-protect them. Write-protected blocks (included block 2) cannever be written to from the moment they are locked
Picotag TranspondersPicotag transponders use 13.56 MHz frequency.

ISO-15693 TranspondersYou can use up to 256 blocks or use one block size up to 256 bits (32bytes). There is no definite memory map organization as it depends onwhat you might implement.
ZPL II Commands for RFID^WT – Write TagThe format for the ^WT instruction is:^WTb,r,m,w,swhere^WT = Write Tag commandb = Block NumberDefault value: 0Other values: 1 to n, where n is the maximum number ofblocks for the tagThis is the starting block number. If the user sends more than a block ofdata it will overflow into the next block. If the user overflows the block andsubsequent blocks cause errors (write protects, beyond range, etc.), thewrite will be aborted, but blocks already written will not revert to originalcontents. It’s up to the caller to ensure blocks aren’t accidentallyoverwritten.r = RetriesDefault value: 0Other values: 1 to 10, number of retriesm = motionDefault value: 0 (Feed label after writing)Other value: 1 (No Feed after writing, other ZPL may causea feed)w = Write protectDefault value: 0 (NOT write protected)Other value: 1 (Write protect)s = Special modeReserved
^RT – Read TagThe format for the ^RT instruction is:^RT#,b,n,f,r,m,swhere^RT = Read Tag command# = Number to be assigned to the FieldDefault value: 0Other Values: 1 to 9999b = Starting Block NumberDefault value: 0Other values: 1 to n, where n is the maximum number ofblocks for the tagn = Number of blocks to readDefault value: 1Other values: 2 to n, where n is maximum number of blocksminus starting block number. In other words, if the tag has 8blocks (starting with block 0) and you’re starting with block 6,n can be 2. This would give you block 6 and block 7information.f = FormatDefault value: 0 ASCIIOther values: 1 Hexadecimalr = RetriesDefault value: 0Other values: 1 to 10, number of retriesm = motionDefault value: 0 (Feed label after writing)Other value: 1 (No Feed after writing, other ZPL may causea feed)s = Special ModeDefault value: 0Other 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^XZThe first ^RT command automatically detects the tag type, starting at block7, reads three blocks of data in ASCII format. It will retry the command 5times if necessary. A “void” label will be generated if the read isunsuccessful after ‘r’ retries. The data read will go into the ^FN1 locationof the recalled format.The second ^RT command automatically detects the tag type, string atblock 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 SetupThe format for the ^RS instruction is:^RStwheret = tag typeDefault value: 0 –NONE (No tags available)Other values:1- Auto detect (automatically determine thetag 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 IDThe format for the ^RI instruction is:^RInwheren = field number to store the unique IDThe unique ID will be read from the tag and available toprint 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 ProgrammingZPL IITM is Zebra Technologies Corporation’s Zebra ProgrammingLanguage II label design language. ZPL II lets you create a wide variety oflabels from the simple to the very complex, including text, bar codes, andgraphics.This section is not intended as an introduction to ZPL II. If you are a newZPL 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 theDocumentation 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-onlyfiles (ex: Microsoft Word® and save as a .txt file) and type in the labelformat 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 afile to the Zebra printer. For example, if your file name isformat1.zplthen type, “COPY FORMAT 1.ZPL XXXX”, where “XXXX” is theport to which your Zebra printer is connected, for example, “COM1” or“LPT1.”5. Compare your results with those shown. If your printout does not looklike the one shown, confirm that the file you created is identical to theformat shown, then repeat the printing procedure. If nothing prints,refer to the “Getting Started” section to make sure your system is set upcorrectly, otherwise refer to the “Troubleshooting and Diagnostics”section.

Manual CalibrationManual calibration is recommended whenever you are using pre-printedlabels (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 backingmaterial. Load the media so that only the backing material is threadedthrough 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 feeduntil 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 inmemory and the printer is ready for normal operation.6. Press the feed button. One entire blank label will feed. If this does nothappen, try defaulting (refer to the four-flash sequence in “Feed ButtonModes” on page 50) and recalibrating the printer.NOTE: Performing a manual calibration disables the auto calibrationfunction. To return to auto calibration, default the printer (see thefour-flash sequence in “Feed Button Modes” on page 50).
Troubleshooting TestsPrinting a Configuration LabelTo print out a listing of the printer’s current configuration, refer to theone-flash sequence in “Feed Button Modes” on page 50.RecalibrationRecalibrate the printer if it starts to display unusual symptoms, such asskipping labels. See “Auto Calibration” on page .
Resetting the Factory Default ValuesSometimes, resetting the printer to the factory defaults solves some of theproblems. Follow the four-flash sequence instructions in “Feed ButtonModes” on page 50.Communications DiagnosticsIf there is a problem transferring data between the computer and printer, tryputting the printer in the communications diagnostics mode. The printerwill print the ASCII characters and their respective hexadecimal values (asample is shown in Figure 23) for any data received from the hostcomputer. To find out how, refer to the power off mode procedure in “FeedButton Modes” on page 50.
Feed Button ModesPower Off Mode (Communications Diagnostics Mode)With the printer power off, press and hold the feed button while you turn on the power. The printerprints out a listing of its current configuration (see Figure 22). After printing the label, the printer willautomatically enter a diagnostic mode in which the printer prints out a literal representation (see Figure23) of all data subsequently received. To exit the diagnostic mode and resume printing, turn off and thenturn on the printer.Power On ModesWith the printer power on and top cover closed, press and hold the feed button for several seconds. Thegreen status LED will flash a number of times in sequence. The explanation at the right (Action) showswhat happens when you release the key after the specific number of flashes.FlashSequence Action* A configuration label prints.***The media sensor calibrates and a media sensor profile prints (see “ManualCalibration” on page 47).******To reset the communication parameters: Press and release the feed button whilethe LED rapidly flashes yellow and green. The serial communication parametersreset 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 LEDrapidly flashes yellow and green. When the printer and host are synchronized, theLED changes to solid green. NOTE: No labels will print during autobaudsynchronization.**********Resets the factory defaults, auto calibrates, and saves settings into memory.***************The print width calibrates. While the status LED alternately flashes green andyellow, a series of stacking rectangles print on the label. When the rectangle printsto the outer edges of the label, press and release the feed button. The label widthand current communication parameters will be saved into memory.*********************The print darkness calibrates. A series of nine samples print, starting with thelightest and ending with the darkest image. When the desired print darkness isachieved, press and release the feed button. The print darkness will be saved intomemory.If the feed button remains pressed after a 7-flash sequence, the printer will ignore the button when itis released.
