Use this chapter to learn how to configure your 7421 printer,communicate with a PC, and print a test label with PrintSet.


You are now ready to configure the printer by downloading datafrom the host to the printer. For your printer to operate mosteffectively, you need to configure:

the media sensitivity number

the print darkness

the label gap sensors

Setting the Media Sensitivity NumberMedia sensitivity is important because you use it to optimizeprint quality. The three digit media sensitivity number (MSN)specifies the amount of heat required by the printhead to image alabel. The amount of heat that each roll of media or ribbon

requires is unique due to different chemistries andmanufacturing processes.

Intermec has developed heating schedules (the amount of heatrequired to image a label) to produce the highest possible printquality for Intermec media and ribbon combinations on Intermecprinters. Look for the three digit media sensitivity number on:

the side of the media roll. Use the last three digits (140 in theexample) of the 15 digit number stamped on the roll for themedia sensitivity number.

a small label attached to the roll of media.

a small label attached to the plastic bag of your ribbon roll.Your label may be different from this example, but it willcontain the media sensitivity number.

Note:Some ribbon rolls have the media sensitivity number printed onthe inside core.

Use this three-digit number to optimize print quality and printspeed on your printer. You can achieve the best print quality on

the printer by using only Intermec ribbon and media products.The default sensitivity setting for thermal transfer media is 567.For direct thermal media, the default sensitivity setting is 180.

To change the media sensitivity number with PrintSet

1. Start the PrintSet application software.

2. Click the Paper type button.

3. In the Print Quality Setup dialog box, enter your three-digitnumber in the Media Sensitivity Number field.

4. Click OK.

5. Download your change to the printer by pressing the buttonto send command updates to the attached printer.

Setting the MSN for Intermec Media and RibbonFor direct thermal media, use the three-digit media sensitivitynumber located on the roll of media to set the media sensitivitynumber. You can also use the values from the tables in the nextsection.

For thermal transfer media, you need to look in two places to

determine the sensitivity number. The media sensitivity numberon each roll of thermal transfer media or ribbon has an asterisk(*) in place of one of the digits. On thermal transfer media, thenumber contains the first and second digits, with an asterisk inplace of the third digit. One the thermal transfer ribbon, thenumber contains the first and third digits, with an asterisk inplace of the second digit.

To optimize the sensitivity number for thermal transfer media,you combine the digits like this:

Media or Ribbon Sensitivity Number Description

third digit to identify theribbons sensitivitynumber.

Setting the MSN for Other Media and RibbonIf you are not using Intermec media and ribbon, or if youmisplaced your packaging with the three digit-sensitivitynumber label on it, you can set an approximate sensitivitynumber. The first column of the Direct Thermal and ThermalTransfer Media Sensitivity Settings tables list the approximatesensitivity settings. To achieve acceptable print quality, enter the

three-digit media sensitivity number (for example, 600).If you are unsure of how to set the media sensitivity number,start with the highest setting, which provides the lowest energy(600 for thermal transfer and 400 for direct thermal), and workyour way down until you achieve the best print quality.

Adjusting the Print DarknessUse the print darkness adjust to fine-tune the darkness of printon your labels. The fine adjustments compensate for variations inthe media (lot to lot), the printhead, or the printer. Thedarkness adjustment is similar to the dark adjust available on acopier. An increase in print darkness increases the energy to the

printhead and results in darker print. A decrease in printdarkness decreases the energy to the printhead and results inlighter print.

Set the darkness after you enter the media sensitivity number.You can adjust the print darkness from + 10 to -10.

To adjust the print darkness with PrintSet


2. Click the Paper type button.

3. In the Print Quality Setup dialog box, adjust the PrintDarkness slider bar until the setting that you want appearsunderneath it.

Adjusting the Label Gap SensorThe label gap sensor detects the gap between labels while theyare being printed. The gap sensor automatically calibrates itselfwhen you first turn on power to the printer. This adjustmentcompensates for manufacturing differences in label stock thatmay make it difficult for the gap sensor to detect the gap

between labels.

To adjust the label gap sensor

1. Turn the printer power off.

2. Turn the printer power on.

The printer Power light flashes yellow and the printer advancesto the next label. When the label gap sensor adjustment iscomplete, the Power light stops flashing and turns green.

Communication Problems

If your printer is not receiving downloaded data, try thesolutions in this table.


Printer does notcommunicatewith the host.

Incorrectcommunicationsparameters.

Use PrintSet to make surethat you have the correctcommunicationsparameters set (such as

baud rate).

Damaged or incorrectI/O cable.

Check the connections atboth ends or replace thecable. See Appendix B forcable information.

Using Data Line Print Mode

Use Data Line Print mode to troubleshoot communicationsbetween the printer and the host, and to test the operation of theprinter. When the printer is in Data Line Print mode, it prints outall downloaded data with the hexadecimal equivalent directlyunderneath it.

To enter Data Line Print mode

1. Turn the On/Off switch to the off position.

2. Press down and hold the Feed/Pause button while turning onthe printer.

The hardware configuration test label prints out and thefirmware program and version number are sent to the host.You are now in Data Line Print mode.

3. Send a few characters down from the host. The printer printsout your data with the hexadecimal equivalent directlyunderneath it.


63/98

4-7

4. Hold the Feed/Pause button down to momentarily suspendthe test. The printer prints a software configuration test label.

5. If you press the Feed/Pause button again, the pitch labelprints.

To exit Data Line Print mode

1. Turn the printer power off.

2. Turn the printer power back on.

Preventing Data LossSeveral problems can cause data loss or communicationsproblems on the printer. Data loss can result in printing errors ormissing field data.

Hardware handshaking involves the use of a hardware wire.Software handshaking involves a two-way datalink between thedevices. The two devices communicate with each other without

losing data through the use of handshaking. The printer sendsboth forms of handshaking simultaneously when the printersinput buffer is full. Any loss of data can cause printing errors ormissing data.

Hardware handshaking uses pin 6 or pin 9 of the RS-232interface to control data flow. When the printer is using IntermecStandard protocol, it holds pins 6 and 9 high when the printer isready to receive data. For help on understanding printerprotocol, see Appendix B, Communications Reference.

The printer holds pins 6 and 9 low when the printer is in one ofthese conditions:

Buffer full Ribbon fault

No label stock

Label at peel-off bar


64/98

4-8

Your printer uses XON/XOFF protocol for softwarehandshaking. When the input buffer is full, the printer transmitsan XOFF character. This action alerts the host to the fact that theprinter buffer is full and cannot receive any more data. When theprinter is ready to receive more data, it sends the XON character.

To check for communications problems

1. Check the cabling from the printer to the host system.

2. Check the interfacing of the devices that are communicatingwith the printer.

3. Check the printer for proper electrical operation of the I/Oport.

4. Test to see that the host system is not overrunning theprinters input buffer.

5. Check to see that the data string being sent to the printercontains the correct information.

Resetting the Printer to Factory DefaultsUse memory reset if you want to return the printer to its defaultconfiguration.

To reset the printer to factory defaults

1. Turn off the printer.

2. Lift the printhead and remove all label stock from the paperpath.

3. Turn the printer on while holding down the Feed/Pausebutton.

4. When the print mechanism starts to move, release theFeed/Pause button and press it again. The Power lightshould now be flashing red.

5. Press and hold the Feed/Pause button down for 8 seconds oruntil the Power light stops flashing. The printer resets allparameters to their factory default settings.

About Communications

The 7421 printer supports both serial and parallelcommunications. Using the parallel interface with an IEEE 1284parallel interface cable (Part No. 590124) provides the bestperformance.

Your printer has the following hardware and softwarerequirements:

The host computer must use the American Standard Code forInformation Exchange (ASCII) for data communications.

A serial port or a parallel port must be available on the host ifyou are connecting directly to the printer.

The host must support the RS-232 or data communicationsinterface.

For information on configuring the host computer, portconcentrator, or network controller, see the reference manual for

the controlling device.

Serial Communication Protocols

Communication protocols are important because they determinethe transmission standards for communications between theprinter and the host. The printer and the host must use the sameprotocol and parameters to communicate properly. The printersupports the flow control and block transfer protocols describedin the next sections. All of these protocols are point-to-point.Application programs and/or ROM BIOS determine whichprotocols your computer can support. For more detailedinformation, refer to the Intermec Data Communications Reference

Manual(Part No. 044737).

Intermec Printer Standard ProtocolIntermec Printer Standard Protocol is a half-duplex protocol. Alldata transmission to the printer consists of status enquiry (ENQ),status dump (VT), or message blocks. Each message block startswith the Start of Text (STX) characters and ends with the End ofText (ETX) characters. Each message block must be 255characters or less, including the STX and ETX characters.


74/98

B-4

The printer returns its highest priority status when it receives avalid block ( data ) or when it receives the statusrequest command . When the printer receives the statusdump command (), the printer returns all active status. Theprinter status response time ranges from 30 ms to 100 msdepending on the complexity of the received message block. Inthe case of a transmission error, the printer responds with a

and discards the entire message block.The table below shows printer status conditions in descendingorder of priority:

Printer Status Character

Buffer already full GSRibbon fault USNo label stock EMBuffer now full DC3Printhead hot SILabel at strip pin FSSkipping DC1Printing DC1Ready/Online DC1

Note:Do not confuse the Buffer now full status with theXON/XOFF characters and .

When the printer returns Buffer Now Full () status, itaccepts the currently received message block. At this time, theprinter can accept short messages to allow parsing of immediatecommands such as Reset () or Cancel Batch Printing(). However, if the printer responds with a to anymessage block, the buffer is already full and the printer discards

the entire message block. In case of a transmission error, theprinter discards the whole message block and responds with aNegative Acknowledgment (NAK). You should retransmit themessage block from the host.


75/98

B-5

XON/XOFF ProtocolXON/XOFF protocol uses the ASCII characters (XON)and (XOFF) to start and stop the flow of data from thehost to the printer. The printer does not restrict the messagelength for XON/XOFF protocol. That is, the printer processesinformation as it is being downloaded and stops when there is

no more information. and are optional characters. However, if you sendan STX, the printer ignores all other characters until you send anETX.

Intermec provides two versions of the XON/XOFF protocol. TheIntermec version of XON/XOFF has the printer respond to eachmessage with its current status. The other version conforms togenerally accepted industry standards that include no end-of-message response being sent to the host other than XOFF. Inaddition, a DC3 is sent to the host if the printer is offline or ifmedia fault occurs. An XON is sent on power up.

Since the printer uses DC1 and DC3 for data flow control, theprinter status characters are different from those of the StandardProtocol.

Printer Status Character

Buffer already full GSRibbon fault USNo label stock EMPrinthead hot SIBuffer now full DC4Label at strip pin FSLabel skipping DC2Printing DC2Ready DC2

If the host ignores the printer sending an XOFF, the printerresends an XOFF after receiving every 15 characters from thehost. In the case of transmission error, the printer discards thecharacters with the error and keeps the rest of the message block.


76/98

B-6

Hardware ProtocolThe printer uses Ready/Busy and DTR (data terminal ready) ofthe RS-232C interface to indicate the printers status. You canconfigure Ready/Busy and DTR independent of each other andindependent of the software protocol you select for the serialport. You can set each pin to one of these four settings: default,

high, flow control, and Ready/Busy.When you set the pin to high, it stays high as long as the printeris powered up.

When you set the pin to flow control, the pin is high when theprinter status is ready. The pin is held low when the printer isoffline or if the buffer is full.

When you set the pin to Ready/Busy, the pin is high when theprinter status is ready. The pin is held low when the printer is inone of these conditions:

Offline

Buffer full No label stock

Ribbon fault

Label at strip pin

When you set the pin to default, it uses flow control if the serialport is set for XON/XOFF protocol. If you are using IntermecStandard protocol, the printer uses Ready/Busy.

User-Defined ProtocolThe printer provides the capability to change protocol characters.However, users may not define their own protocol. You cansubstitute characters you want to use as protocol characters, butthe rules for the chosen protocol do not change. The printer doesnot use any protocol characters that you replace with the NULcharacter. One table of protocol characters exists. You mayredefine these characters to create a table that all of the protocolscan use. One possibility for the user to redefine protocolcharacters might be the replacement of control characters withprintable characters.


77/98

B-7

Note:Please use caution when replacing control characters withprintable characters. You cannot replace one control character withmore than one printable character.

The following table lists the protocol characters that you canredefine and the protocols they affect:
