Overview
Overview
The R4Mplus “smart” label printer-encoder serves as a dynamic tool for both printing and
encoding RFID labels, tickets, and tags. The printer encodes information on ultra-thin UHF
RFID transponders embedded in “smart” labels. It then immediately verifies proper encoding
and prints bar codes, graphics, and/or text on the label’s surface. For more information about
RFID media, see RFID “Smart” Labels on page 17.
Function of an encoded “smart” label depends on factors such as where the label is placed on
an item as well as on the contents of the item (such as metals or liquids). Contact the supplier
of your RFID reader for assistance with these types of issues.
Transponder Placement
Communication between the “smart” label and the printer is established when the transponder
lines up with the printer’s antenna. The optimal transponder position varies with the
transponder size, its configuration, and the type of RFID IC chip used.
Print quality may be affected by printing directly over the transponder. In particular, there is an
area on each label immediately around the location of the IC chip where the printer may print
with low quality. Design your printed label around the location of the chip in the type of
approved “smart” label that you select. For the list of approved transponders and related
placement specifications, go to http://www.rfid.zebra.com/r4m.htm.
!Important • It is important to use transponders that have been specifically approved
for use in the R4Mplus printer. Failure to do so may result in the inability to read or
write to the embedded RFID tags. As new transponders become commercially
available, Zebra will evaluate them for compatibility with this printer. For the list of
approved transponders, go to http://www.rfid.zebra.com/r4m.htm.

ZPL II Commands for RFID
R4Mplus User Guide 73
ZPL II Commands for RFID
Printing and encoding (writing) of “smart” labels is handled through the use of Zebra
Programming Language (ZPL). Each transponder has memory that can be read from through
ZPL commands, and most transponders have memory that can be written to. The printer
divides the ZPL commands that it receives into two categories: RFID and non-RFID (such as
the printing commands for bar codes or human-readable text). RFID commands are executed
first.
ZPL commands also provide for exception handling, such as setting the number of read/write
retries before declaring a transponder defective. For example, if an RFID transponder fails to
program correctly or cannot be detected, the printer ejects it and prints the word “void” across
the label. This process continues for the number of RFID tags specified by the ^RS command
using the same data and format. If the problems persist, after the specified number of tags are
ejected, the printer removes the customer format from the print queue and proceeds with the
next format (if one exists in the buffer).
The following pages provide the ZPL II commands that can be used for RFID applications.
!Important • If a parameter is designated as not applicable, any value entered for the
parameter will be ignored, but the place holder for the field is required.

Sample of RFID Programming
ZPL II is Zebra’s 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
the ZPL II Programming Guide (part number 46530L) or go to http://support.zebra.com to
download the guide.
For your programming, do the following:
1. Set up the printer and turn the power On (I).
2. Use any word processor or text editor capable of creating ASCII-only files (for example,
use Microsoft® Word and save as a .txt file) and type in the label format exactly as shown
in the sample label format that follows.
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 (such as 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
•Printer Setup on page 7
•Printer Operation on page 21
•Configuration on page 45
•Troubleshooting on page 93
to make sure that your system is set up correctly.

Clean the Interior
Remove any accumulated dirt and lint from the interior of the printer using a soft bristle brush
or vacuum cleaner.
Clean the Printhead and Platen Roller
You can minimize printhead wear and maintain print quality with regular preventive measures.
Over time, the movement of media/ribbon across the printhead wears through the protective
ceramic coating, exposing and eventually damaging the print elements (dots). In order to avoid
abrasion:
• Clean your printhead frequently and use well-lubricated thermal transfer ribbons with
packagings optimized to reduce friction.
• Minimize printhead pressure and burn temperature settings by optimizing the balance
between the two.
• Ensure that the thermal transfer ribbon is as wide or wider than the label media to prevent
exposing the elements to the more abrasive label material.
For best results, perform the following cleaning procedure after changing every roll of ribbon.
Inconsistent print quality, such as voids in the bar code or graphics, may indicate a dirty
printhead.
To clean the printhead and platen roller, refer to Figure 33 and complete
these steps:
1. Open the printhead assembly.
2. Remove the media and ribbon.
3. Use the Preventive Maintenance Kit (Zebra part number 47362) or a solution of
90% Isopropyl alcohol and 10% deionized water and swab. Wipe along the print elements
from end to end. The print elements are on the brown strip just behind the chrome strip on
the printhead. Allow the solvent to evaporate.
4. Manually rotate the platen roller and clean thoroughly with solvent and a pad.
5. Brush or vacuum any accumulated paper lint and dust away from the media and ribbon
paths.
6. Reload media or ribbon, and close the printhead assembly.
Note • The printer can remain on while you are cleaning the printhead. In this way all label
formats, images, and all temporary parameter settings stored in the printer’s internal memory
are saved. In addition, keep the peel engaged while cleaning the platen roller (media must be
unloaded to do this) to reduce the risk of bending the tear-off/peel-off bar.
Caution • Ensure that the printhead is fully open and engaged in the up position. If the
printhead is not latched in the up position, it could fall on your hand during the procedure.

Printer Diagnostics
Printer Diagnostics
These self tests produce sample printouts and provide specific information that help determine
the operating conditions for the printer.
Each self test is enabled by pressing a specific front panel key or combination of keys while
turning the printer On (l). Press the key(s) until the DATA light turns off (approximately five
seconds). When the Power-On Self Test is complete, the selected self test starts automatically.
Power-On Self Test
A Power-On Self Test (POST) is performed automatically each time the printer is turned on.
During this test sequence, the front panel lights and liquid crystal display (LCD) monitor the
progress of the POST. If the printer fails any of these tests, the word FAILED is display. If this
occurs, notify an authorized Zebra reseller.
Note • Keep the following in mind while performing self tests:
• When performing self tests, avoid sending a label format to the printer. In the
case of a remote host, disconnect all data interface cables from the printer.
• When cancelling a self test prior to its actual completion, always turn the printer
Off (O) and then back On (I) to reset the printer.
• When performing these self tests while in the Peel-Off Mode, you must remove
the labels as they become available.
• If your media is not wide enough or long enough, unexpected or undesired
results may occur. Ensure that your print width is set correctly for the media
you are using before you run any self tests, otherwise the test may print on the
platen roller. See PRINT WIDTH on page 53 for information on setting the print
width.

FEED Self Test
See Figure 37. The FEED Self Test prints labels at various darkness settings above and below
that of the darkness value currently stored in the printer (shown on the first line of the
configuration label). The relative darkness value printed on the best FEED Self Test label is
added to or subtracted from the darkness value. The resulting numeric value (0 to 30) is the
best darkness value for that specific media and ribbon combination.
For example, if the darkness value on a printer is 10 and the best relative darkness value is
zero, leave the darkness setting as is. If the best relative darkness value is –1, change the
darkness setting on your printer to 9 (10 – 1). If the best relative darkness value is 2, change
the darkness setting to 12 (10 + 2).

Serial Data Port
Hardware Control Signal Descriptions
For all RS-232 input and output signals, the R4Mplus printer follows both the Electronics
Industries Association (EIA) RS-232 and the Consultative Committee for International
Telegraph and Telephone (CCITT) V.24 standard signal level specifications.
When DTR/DSR handshaking is selected, the Data Terminal Ready (DTR) control signal
output from the printer controls when the host computer may send data. DTR ACTIVE
(positive voltage) permits the host to send data. When the printer places DTR in the
INACTIVE (negative voltage) state, the host must not send data.
Request to send (RTS) is a control signal from the printer that is connected to the clear to send
(CTS) input at the host computer. RTS is always active (positive voltage) when the printer
is on.
RS-232 Serial Data Port
The connection for this standard interface is made through the female DB-9 connector on the
rear panel. A DB-9 to DB-25 interface module is required for all RS-232 connections through
a DB-25 cable (see page 110 for details).
For all RS-232 input and output signals, the printer follows both the Electronics Industries
Association’s (EIA) RS-232 specifications and the Consultative Committee for International
Telegraph and Telephone (CCITT) V.24 standard signal level specifications.
Table 18 shows the pin configuration and function of the rear panel serial data connector on
the printer.
Note • When XON/XOFF handshaking is selected, data flow is controlled by the ASCII
Control Codes DC1 (XON) and DC3 (XOFF). The DTR Control lead has no effect.

Parallel Data Port
Parallel Data Port
The 8-bit parallel data interface supports IEEE 1284 bidirectional parallel communications in
nibble mode. The parallel interface provides a means of communication that is typically faster
than the previously mentioned serial interface methods. In this method, the bits of data that
make up a character are sent all at one time over several wires in the cable, one bit per wire.
Parallel Cabling Requirements
An IEEE-1284 compatible bi-directional parallel data cable is required when this
communication method is used. The required cable must have a standard 36-pin parallel
connector on one end that is plugged into the mating connector located at the rear of the
printer. The other end of the cable connects to the printer connector at the host computer. Port
selection for status information is determined each time the printer is turned on.
