Terminal

Configuration

Information

In order to successfully use the TR220, the 5V output signal must be activated, and a printing library needs to be installed. The printing li brary, printer manual, printcap file and sample printing code are included in the Symbol SDK. Symbol software tools are available online at:

http://devzone.symbol.com

External 5V Signal The terminals each require particular software

drivers that enable Palm and Windows CE ap plications to control the activation of the exter nal 5V signal. However, these drivers are not readily found on all terminals nor do they all work the same way. The steps required by each terminal to allow for the control of the external 5V signal are given below.

SPT 1700 The power driver (powerdrv35r.prc) and trigger

scan mgr (1700_trigger_scanmgr.prc) must be installed through a Hot-Sync operation followed by a soft reset. Once installed, the application developer then initializes the serial communication port with the "srmOpen" function and "upwr" port parameter to activate the external 5V signal.

SPT 1800 The power driver for the SPT 1800 is pre-installed

and does not require any other software installa tion. By initializing the serial communication port with the "srmOpen" function and "upwr" port pa rameter, the external 5V signal is activated.

PPT 2700 and

Operator Maintenance

This section provides information on operator maintenance procedures for your printer.

Maintaining Your

Printer

The printer requires regularmaintenance to optimize printing and extend the serviceable life of your printer. Zebra Technologies uses only high quality components and materials in its printers. The printers are manufactured and tested under a strict quality management program. Although only minimal routine maintenance is required, following these simple maintenance guidelines will ensure longer life with quality printing performance.

The printer’s design allows for cleaning of printer’s media path. The operator can safely clean the print head, platen roller and areas ad jacent to the media path surfaces by following the simple procedures and guidelines on the following pages.

980402-001 Rev.A 17

Page 24

Media, Cleaning

and Handling

The printer requires periodic cleaning to maxi mize the print quality and print head life. The main factors that contribute to reduced head life (and platen life) are:

Touching the print head! Static electricity can discharge and damage the print head. The body’s oils and acids also damage the print head.

Cleaning - For optimum performance, clean the print head regularly after every 3-5 rolls of media.

Abrasion - Over time, the movement of media across the print head will wear through the protective ceramic coating, exposing and eventually damaging the print elements (dots).

Use of proper media - Use only approved media. Non-approved media may contain chemicals that can destroy or dramatically reduce the print head’s life.

Temperature - Print head density (heat) setting. Set the density to the lowest possible setting that prints a good image.

Using Zebra Technologies approved media also helps ensure that your printer will have a longer life with quality printing performance.

Print Care

Guidelines

Remove the outer layer of media from the la

bel roll before loading media. Tape or adhe sive that holds the loose end and the outside length of media becomes contaminated when handled or stored. When you remove this part of the media, you remove poten tially contaminating oils, dust, and adhe sives.

Clean the print head every 3-5 label rolls.

•

Clean the platen (drive) roller to remove con

•

taminates. Note - Paper or label liner parti cles do not normally affect print operation.

Cleaning the Print

As you use your printer, the print head may become contaminated resulting in poor print quality. Every 3-5 rolls of media the print head should be cleaned with a cleaning pen.

black and colored areas of the print head. Allow the print head to dry for 1 minute before loading media.

980402-001 Rev.A 19

Do Not Clean the Print Head with sharp ob jects! Only used approved cleaning materials.

Page 26

Cleaning the

Printer

Cleaning the outside of the printer is not gener ally recommended except in cases where the contaminates may migrate to the media or the platen roller (both contact the print head).

Linerless media printers need additional clean ing to avoid adhesive buildup on the ribs in the media path near the platen roller.

Always Remove The Battery And Terminal Before Cleaning the Platen Roller or General Printer Cleaning.

Do Not Clean The Battery.

Do Not Clean the Printer’s Serial Port Connector.

The exterior surfaces and the media path surfaces (except the print head) can be cleaned with a lint free, clean, damp cloth very lightly moistened with medical grade alcohol. Medical grade alcohol (95% pure or better) may be used to help remove any adhesive or label material buildup.

Avoid cleaning the media sensors. Remove ac cumulated dust with a dry swab from the sen sors by gently wiping them off. If adhesives or other contaminates get on the sensor, then an alcohol moistened swab may be used. Clean several times to remove any film that may be left from the initial cleaning or sensors may not function properly. Using too much alcohol can allow it to get between the electronic compo nents and will require a much longer drying time before the printer will function properly.

980402-001 Rev.A

Page 27

Cleaning the

Platen Roller

The standard platen (drive) roller normally does not require cleaning. Paper and liner dust can accumulate without effecting print opera tions. Contaminates on the platen roller can damage the print head or cause the media to slip when printing. Adhesive, dirt, general dust, oils and other contaminates should be cleaned immediately off the platen.

The non-stick platen roller on Linerless media printers requires frequent cleaning to keep ad hesive buildup from occurring and transferring to the print head and the media path.

The platen can be cleaned with a fiber free swab (such as a Texpad swab) or a lint free, clean, damp cloth very lightly moistened with medical grade alcohol (95% pure or better). Do

Not Use the Cleaning Pen!

1 Open the media door and remove the media. 2 Clean the platen surface with the alcohol moist-

ened swab. Rotate the platen while swabbing. Repeat this process two to three times with a new swab to remove residual contaminates. Adhesives and oils, for example, may be thinned by the initial cleaning but not com pletely removed.

General Printer

Configuration

Information

The TR 220 mobile printer has features that re quire special consideration when program ming. The EPL2 command support has been modified to maximize battery charge utilization and ignore unusable features. Some of the features and commands that need special con sideration when developing applications in clude the following:

The TR 220 printer operates in Single Buffer

•

Mode only. Single buffering increases the maximum

•

image buffer size to 2235 dots long (22 inches/ 558.8mm) with the maximum print width of 384 dots (1.89 inches/ 48 mm).

• Speed (S) is automatically adjusted to maxi- mize battery life. It can not be set by programming.

• Density (D) has a default value of 10. The programmer should set this value to the lowest level that produces ausable label to maximize battery life.

• The use of large, highly dot dense images (solid black) is not recommended. This will reduce battery charge utilization. The printer is rated to print at 25% density (3mm solid black bar across the print width alternated with a 9mm non-printing bar or an equiva lent density pattern).

•

Long multiple label or high density print jobs may cause the printer to temporarily delay printing operations while the motor or print head cool to safe operation temperatures.

•

The Enable Error Reporting (US) command enables the command syntax error reporting via the orange printer status indicator.

U% Host Prompts/Motor Temperature

Description EPL2 Mobile Printers Only (TR 220) - This

command will cause the printer to send to the host the motor temperature status through the mobile printer’s serial port.

Syntax

The printer will send motor temperature in 2ºC increments to the host via the serial port. The printer uses the data format of NNdeg C, where NN equals the motor temperature.

Range Reported (

Degrees Celsius): 24≤NN<60

EPL2 Mobile printers suspend printing operations, including printer to host communication, until the motor returns to safe operating temperatures.

The mobile printer will stop printing are 60ºC or higher.

Example:

980402-001 Rev.A 37

The printer will resume printing at 50ºC.

U%¿ : Command sent to printer

: Printer responds with motor temperature : 24 deg C

Page 44

U$ Host Prompts/Battery Status

Description EPL2 Mobile Printers Only (TR 220) - This

command will cause the printer to send to the host the battery charge status.

Syntax

The printer will send information about battery charge status in increments of 10 percent. The printer uses the data format of VccNNN%, where NNN represents the battery’s charge level.

EPL2 Mobile printers suspend all new printing operations, including printer to host communication, until the battery charge level is greater than 20%.

Print jobs or forms (single label or batch operations) will continue processing until finished.

The mobile printer will accept new commands and print after the battery charge is greater than 20%.

Example:

38 980402-001 Rev.A

U$¿ : Command sent to printer

: Printer responds with : Vcc90%

US Enable Error Reporting

Description Use this command to enable the printer’s status

reporting feature.

Serial Port - If an error occurs, the printer will send a NACK(0x15), followed by the error number, to the computer. If no errors occur, the printer will echo ACK(0x6) after each P com mand.

If paper or ribbon empty occurs, the printer will send, through the serial port, a”-07” and “Pnnn” where nnn is the number of labels re maining to print.

Mobile Printers Only (TR220) - Enables command error reporting via printer’s status indicator, as well as, the serial port.

Syntax

US[p1]

The printer’s default setting is off.

Parameters p

If no errors occur, the printer will echo ACK(0x6) after each label that is successfully printed.
