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 SignalThe 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 1700The 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 1800The 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.

Language
980402-001 Rev.A13
The driver is pre-installed on the PPT 2700 and
PPT 2800 terminals. By selecting “Com7” as
the active serial communication port, the exter
nal 5V signal is automatically activated.
For SPT 1700 and SPT 1800 terminals, you
must use EPL2 Page Mode commands via the
"ptwriteprinter" command. Refer to the Symbol

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 maintenanceisrequired,followingthesesimple
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.A17
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-approvedmediamaycontain
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.

black and colored areas of the print head. Allow
the print head to dry for 1 minute before loading media.
980402-001 Rev.A19
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.
-
20
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!
-
-
1Open the media door and remove the media.
2Clean 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, maybe
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 thehost the motor temperature status through the
mobile printer’s serial port.
Syntax
U%
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 (
U%
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.

U$ Host Prompts/Battery Status
Description EPL2 Mobile Printers Only (TR 220) - This
command will cause the printer to send to thehost the battery charge status.
Syntax
U$
The printer will send information about battery
charge status in increments of 10 percent. The
printer uses the data format ofVccNNN%,
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%.

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.
