Safety Summary
Warning and caution messages appear throughout this manual. They alert you to potentially safety hazards or
potential damage to equipment. The messages and there meaning are shown below.
WARNING
Calls attention to practices that could cause
Calls attention to improper practices that could
result in a potentially serious, even lethal injury.
Familiarize yourself with proper procedures before operating or repairing the equipment. Follow these precautions
for your own safety.
Personal Safety
• Treat every circuit as if it is “Live”. If in doubt,
check with a neon tester or voltmeter.
• Know how to turn off power in the work area
and how to obtain help in an emergency.
• Don’t work on equipment under power unless
it’s absolutely necessary. If you must, use
extreme caution.
• Shock. Don’t under estimate the danger of
shock. 12 mA causes hand muscles to
contract, so you cannot free yourself; 24 mA
has proven fatal.
• Tools. Use the right tools for the job. A tool
which slips can cause a short -- or a shock.
When working on live circuits, use tools with
insulated handles.
• Safety Devices. Don’t bypass safety devices,
particularly fuses. If a hot wire shorts to an
ungrounded frame, the frame itself becomes
hot and potentially dangerous.
• Electrical Fires Use Type C, BC, or ABC
extinguishers only.
minor injury or that could cause damage to
equipment.
Equipment Safety
Your body is a giant capacitor. It can store several
thousand volts of electricity. Digital equipment is
easily damaged or destroyed by this static
electricity. You don’t have to see a spark to ruin an
IC -- 50 volts is enough. To protect the equipment
from static damage, follow these guidelines:
• Ground yourself before reaching into the
equipment or touching any circuit board or
other electrical component. The Monarch Static
Ground Kit contains everything you need.
• Re-ground whenever you have walked away
and returned to the equipment. Be especially
careful around carpet. Carpet is a major
source of static buildup in the body. Even a
few steps can recharge you.
• The smaller the object, the greater the
precautions must be. A board in the machine
is better protected than one which is not
plugged in; a chip on a board is better
protected than one in your hand.
• Avoid touchings pins coming out of a chip or
the connector edge of circuit boards. These
metal parts have signal and data lines which
are connected directly to fragile circuits.

Figure 1 - 1. 9830 Printer (Housing removed)
The printers have a hinged print assembly for ease in
loading and unloading the supply. The supply spool,
lower paper guide, and ribbon spool are center
justified and can be adjusted by the user to handle
various supply widths.
The printers support fanfold or roll supply. The 9835
supports tag stock to 10 mil thickness. Standard,
smudgeless, durable, and steam resistant ribbon types
are supported by all printers. Ribbon length is 600
meters and is available in core widths of 1.3”, 1.6”,
2.16”, 3.15”, and 4.13”. Used ribbon is collected on a
take-up spool by taping the ribbon leader to an empty
core. One empty core is supplied with the printer.
The 9830/9835 models offer a Service installed tear
bar, Flash ROM programming, and an optional Peel
Module for separation of supply and backing. The
Peel Module is standard on the 9830, optional for the
9835, but not available on the 9820. The 9835
supports either a Peel Module or a knife, but not both.

9820/9830/9835 Service Manual Functional Description
Power Transformer Assembly
The power transformer assembly is located beneath
the printer’s back cover and includes three
components:
Inlet Power Module
The power module is attached to the printer’s rear
panel just in front of the Control Board Assy. Its face
plate partially extends through the rear panel to allow
users access to the power receptacle, fuse box/power
selector and the on/off switch. It has wire attachments
to ground the Power Transformer.
This module includes the following components:
• International line cord receptacle
• 4.0 Amp, 250VAC Slo-Blow fuse
Line voltage enters at the cord receptacle and passes
through a slow-blow fuse. The slow-blow fuse protects
the system from damage by power surges. Line
ground is provided to the printer via a ground harness
connected to the bottom frame.
Power Transformer
The power transformer is available in three voltages:
110V, 115V, or 220V. It is attached to the frame base
just below the print module. The transformer gets AC
line voltage from the inlet power module and converts
it to two AC output voltages. The first is sent directly
to the Control Board Assembly for futher conditioning.
The second output is sent to the bridge rectifier for
additional conversion.
The power transformer assembly outputs the required
AC and DC voltages for operation of the printer and
sends both voltages directly to the Control Board
Assy. Further conversion and/or distribution is made
by the Control Board Assy. Major functions of the
power transformer include providing power to the Inlet
Power Module, Power Transformer, and to the Bridge
Rectifier.
Bridge Rectifier
The bridge rectifier is a 1” x 1” assembly fastened to
the printer frame base left of the power transformer. It
has wire attachments to ground, the power
transformer, and the Control Board Assy.
The bridge rectifier accepts the AC from the power
transformer and converts it to DC. This voltage is
then supplied to the Control Board Assembly for
further conversion.
CONTROL BOARD
ASSEMBLY
The Control Board Assembly is located on the back
side of the printer frame wall beneath the printer’s
back cover. It consists of a mother board and a
daughter board. The two boards are replaced as a
single assembly. The board assembly is mounted on
six quick-release aluminum standoffs. Three of the
standoffs are threaded for retainer screws.
The board has three connectors (serial port, parallel
port, and bar code verifier), the print contrast control,
and three DIP switch assemblies. Two are mounted
on the long vertical side allowing for external access.
The third DIP switch is located on the daughter board.
There is a connector across the top of the board and a
hall effect sensor at the top right corner of the board to
sense a “Head Open” condition. Eight additional
connectors accept cabling to other printer assemblies.
The daughter board has a connector for cabling to the
mother board, and two connectors for functional
expansion.
Functional Description
The Control Board Assy. controls all electrical
requirements for the printer and contains interfaces for
controlling all printer functions, including Ribbon
Supply and Take-up motors, Stepper Motor, Peel
motor, Knife motor, and the Printhead. A single
microcomputing unit consisting of a 32-bit RISC
processor, 256K OTPROM (16 bits), and 256K (16
bits) of Dynamic RAM (DRAM) controls the interfaces.
Major functions of the Control Board Assy. are:
• Power Conversion
• Memory
• Printer Control
• Operator Panel Control
• Communications
• Contrast Control
• Hardware Power-up Settings (DIP Switches)
• Peel Motor Control
• On-Demand Sensor Interface
• Knife Motor
8 TC9830SM Rev. B 7/98 Confidential July 1998
Functional Description 9820/9830/9835 Service Manual
Power Conversion
Power conversion interface receives AC and DC
voltage from the Power Transformer assembly.
35VAC is converted to +12VDC and -12VDC, while
the 40VDC input is converted to +25VDC and +5VDC.
Memory
Control Board Assebmly contains three types of
memory: Flash, DRAM and SRAM.
Flash Memory
Flash memory contains the necessary BOOT code
and Operating System functions for I/O routines used
for communications, the application program, fonts,
formats, and the Kernel/Library functions.
DRAM Memory
DRAM is used for variable storage, buffers, and image
memory. The base memory configuration for the
printer is 256K (16 bits).
SRAM Memory
SRAM (32K of non-volatile static RAM ) is used to
store system parameters and machine totals. All
relevant information is automatically stored in the
SRAM when the printer is turned off.
Printer Control
Control Board Assembly controls all printer functions.
It use a high performance, 32-bit, RISC based,
integrated microcontroller. The microcontroller
performs imaging and provides interfaces to printer
control operations. Major functions of the board are:
Data Handling
During operation, communication with both the RS232 port and the High Speed parallel port is
maintained. MPCL data received is transferred to
Dynamic RAM (DRAM)
Printhead Thermal Control
Printhead thermal control operation is a dynamic
closed loop servo circuit that adjusts the on/off duty
cycle in response to a continuously monitored
Printhead operating temperature and resistance.
Print Imaging
The Thermal Printhead Interface is controlled by the
microcontroller. Page image data is transferred from
Dynamic RAM to the thermal printhead as a serial
data stream.
Motion Control
Motion control sub-system controls four DC motors.
Two DC motors drive the Ribbon control, a stepper
motor controls the platen drive, and a fourth motor
drives the Peel Module.
Platen Drive Interface
Control Board Assembly controls the platen drive
motor’s torque, speed and direction through the use of
four phased 25Vdc output signals. Motor torque and
direction is controlled by changing the sequence and
pattern of the four signals. Motor speed is controlled
by increasing or decreasing the speed of the digital
pulse that make up the four phased signals.
Ribbon Drive Interface
Electronically controlled DC motors drive the ribbon
over the printhead. The motors, and associated
control software, control the tension of the ribbon web
as the ribbon spools from the supply side to the takeup side. A speed-detection method using BEMF
(Back Electromagnetic Motor Force) provides
accurate ribbon tension control.
Analog to Digital Conversion
An ML2255 A/D converter, in conjunction with the
microcontroller, monitors system functions. The A/D
converter combines an 8-Bit A/D converter, 8-channel
analog multiplexer, and a microcontroller-compatible,
8-bit parallel interface and control logic. The A/D
converter monitors various system functions and
provides information to the printers firmware to control
the supply motion, print quality, etc.
Supply Detection & Tracking System
See Chapter 8, “Supply Sensing Systems” for more
information.
Operator Control Panel
Printer Control Board uses a Peripheral Interface Unit
(PIU) to control the operator control panel interface
comprised of a three digit display, three push-button
keys and three LEDs.
An optional 917 Keypad is available for the 9835
printer (offline batch entry).
Communications
RS-232 interface and the Centronics/IEEE 1284
compliant parallel interfaces are mounted on the
Control Board Assy. Both are located on the left edge
of the board and accessed by the user at the rear of
the printer near the supply roll.
July 1998 TC9830SM Rev. B 7/98 Confidential 9
9820/9830/9835 Service Manual Functional Description
RS-232 interface
This interface allows connection to devices capable of
RS-232 communications. The interface is incorporated
in the microcontroller and has DIP switches to set
communications parameters. The DIP switches can
be set manually by the user or through software
control.
Centronics IEEE-1284 Parallel Interface
This interface accommodates high data rates, up to
2M Bits/Second.
IEEE 1284 Bi-Directional Parallel Interface
An IEEE 1284 High Speed Bi-directional Parallel
interface provides parallel communications. The
microcontroller directly controls the port. The
interface allows compatibility with the Centronics
interface as well as allowing for High Speed Bidirectional communications.
NOTE: Third party LAN devices are connected
through the parallel interface to allow the
printer to interface different LAN networks.
Contrast Control
A manual contrast control, located at the edge of the
Control Board Assy., extends out of the rear cover. It
is used for fine adjustments to the print contrast
values.
Hardware Power-up Settings (DIPS)
Two 8-switch DIP switches, located on the back panel
of the printer above the contrast adjustment, control
the default power-up configuration of the printer.
Settings include the serial port settings, diagnostics,
ribbon setup, printer mode and supply type.
Peel Module Assembly
The peel module separates the supply from the
backing paper. It consists of an on-demand sensor,
rollers, and a 12Vdc motor drive. Dip SW1 (switch 2)
located on the daughter board enables and disables
the peel function.
PRINT ASSEMBLY
This Print Module is a plastic casting located inside
the printer’s hood. It is attached to the mid frame by
two bearing blocks which capture studs on the module
back plate. Components of the Print Module are:
Figure 2- 1. Print Assembly
Thermal Printhead
The printhead is located at the bottom front of the
module. It is held in place by a plastic carrier which
acts as an interlock to a formed metal bracket. The
bracket is center-mounted and pivots to ensure an
even pressure on the supply. The printhead bracket
has two alignment loops which slip over the platen
roller to assure dot row to platen roller alignment. The
printhead mount also has two spring loaded
adjustment knobs to adjust printhead pressure for
wide or narrow supplies. A 30 pin ribbon cable
connects the printhead to the Control Board Assy
Ribbon Supply & Take-up Spools
The ribbon supply and ribbon take-up spools are
located on the supply side of the module. Each spool
shaft extends through the module wall and connects to
its own DC drive motor. The spools are designed to
handle a detented ribbon core so when ribbons of
various widths are installed they maintain center
justification.
Ribbon Transfer Rollers
Two ribbon transfer rollers are located on the supply
side of the module. The rollers are ribbed and
attached to metal shafts by retainer screws. One sits
at the very front of the module wall above the
printhead while the other is positioned just above the
supply deflector.

Functional Description 9820/9830/9835 Service Manual
Ribbon Spool Drive Motors
wo DC ribbon drive motors are mounded to the back
of the module wall. Each motor drives a ribbon spool.
The motors are connected directly to the Control
Board Assembly via separate two-wire harness.
Supply Deflector and Bi-Cell Emitter
(IR LED)
See Chapter 8, “Supply Sensing Systems” for more
information.
Ribbon Transfer Rollers
The two ribbon transfer rollers allow ribbon tension
adjustments. Each roller has an eccentric which
allows slight skew adjustments to each, which in turn
affects the ribbon tension.
Functional Description
The print module, performs ribbon drive operations,
provides mechanical ribbon tension adjustments,
performs print functions, helps maintain supplies
tracking, and houses half of the sensor assembly. It is
controlled by the Control Board Assembly.
Ribbon Drive Operation
The ribbon drive operation is made up of two ribbon
spools, two 25Vdc drive motors, and two ribbon
transfer rollers. It is controlled by the Control Board
Assy. Each drive motor sends continuous information
to the Control Board Assy. where it is used to evaluate
ribbon conditions, maintain optimum ribbon tension,
and sense the end of ribbon condition. This system
eliminates the need for ribbon sensors.
Printing
The printhead has a line array of 832 dot elements
sized to produce 203 dots per inch. Printing occurs by
sending image data to the printhead one line at a
time. Each time a line of data is received,
corresponding dots on the printhead are heated to
create an image line on the stock. Successive image
lines generated across moving stock make up the total
image. The Control Board Assy. controls all image
data sent to the printhead, and regulates the energy
level of the printhead. Energy levels are raised and
lowered to create darker or lighter print respectively.
FEED ASSEMBLY
The feed module components are mounted on a metal
frame positioned beneath the Print module and
fastened to the printer base. Components of the feed
module are:
Bearing
Blocks
Spring
Latch
Figure 2- 2. Feed Assembly
Platen Module
The platen rollers are on top of the feed module frame
just beneath the printhead. It is held in place by two
bearing blocks latched on the frame sides. The inner
side of the platen roller shaft extends through the
inside wall of the feed module where a drive gear is
attached.
24VDC Stepper Motor
The stepper motor is located behind the mid-frame of
the printer. Its drive shaft and gear extends through to
the space between the printer mid-frame and the feed
module frame.

Printhead Latch
The printhead latch is spring loaded and mounted on
the outside of the feed module frame; within the latch
fascia. It locks the printhead in position.
Functional Description
The feed module transports supply through the printer
and across the printhead. It also maintaining proper
alignment, tension, and speed. This is accomplished
by sensing the stock position while securing the
printhead down onto the platen roller. Major functions
are supply feeding and supply sensing. See Chapter
8, “Supply Sensing Systems” for more information.

12 TC9830SM Rev. B 7/98 Confidential July 1998
CHAPTER 3 TROUBLESHOOTING
This chapter contains suggestions for diagnostic and repair actions.
PRELIMINARY CHECK
The following checks should be made before going further:
1. Are the DIP switches set properly to match communication values and existing supply?
See Chapter 1 for DIP Switch settings and procedures.
2. Ensure that the proper fuse has been installed. See the Operator’s Handbook.
3. Inspect printhead to ensure it is locked in place.
4. Ensure stock and ribbon are properly loaded. Refer to the Operator’s Handbook for printer loading instructions.
ANALYZING FAILURE DURING POWER UP
Each time the printer is turned on, it runs Power-up Diagnostics. These Level 0 Diagnostic Tests are described in
detail in Chapter 4. If any of the first eight tests result in a fault condition, a three digit status code is indicated on the
Control Panel LCD. As shown in Figure 4-2, if any of the following status codes are indicated, the printer will stop
operating, and remain in a “hold mode” until CLEAR is pressed:
909 Memory Failure 765 Printhead Test Failure
911 Virgin Reset
NOTE: These error codes only appear during a power-up test sequence. If a “765” status code is indicated during
the power on tests, the printer is still operational but may not be able to print all of the commanded label
images.
The Control Panel is tested during the power-up tests by blanking the three digit LCD display momentarily. This is the
final Level 0 test, and would be noticed only if a “765” status code were previously indicated.
EVALUATION OF A 616 ERROR (DOT SHIFTING FAILED)
This error occurs if at least one dot element is non-functional. Shifting the image pattern will not work. You must
replace the printhead.
EVALUATION OF A 704 ERROR (OUT OF SUPPLY)
This error occurs when the sensor is not sensing the supply. This can happen if there is a problem with the supply or
with the sensor. Perform the following procedure:
1. Verify stock is loaded and properly aligned in the supply guide.
2. Verify that DIP switches and online settings are set for proper supply type.
3. Check Bi-cell alignment using gray scale, and check operation using diagnostic procedures (be sure to check
the harness). See Sensor Tests and Bi-Cell Sensor Adjustment, in Chapter 8, for instructions.
4. Verify Emitter is operational (including the harness) by using an infrared detector probe.
July 1998 TC9830SM Rev. B 7/98 Confidential 13
9820/9830/9835 Service Manual Troubleshooting
EVALUATION OF A 754 ERROR (OUT OF RIBBON)
This error occurs whenever the ribbon stops turning. This can happen if the motors are not working, the stock is
binding, the platen is sticky, or if any condition is present that prevents ribbon rotation. Perform the following
procedure:
1. Verify Ribbon Motors are turning. If they are not, check connectors to the Control Board Assy. and the
connections to the motors.
2. Verify Platen Motor is feeding. If is is not, check the connections.
EVALUATION OF A 755 ERROR (PRINTHEAD OPEN)
This error occurs if the printhead is not functioning properly. Perform the following procedure:
1. Ensure the printhead is properly latched.
2. Verify that the magnet is present and inserted properly.
3. Verify that sensor is functioning properly.
EVALUATION OF A 765 ERROR (PRINTHEAD FAILURE)
This error occurs if a dot is out of specification. This error can occur even if print quality is not visibly affected.
Operation can be continued until the problem is corrected. Perform the following procedure:
1. Check connections to the printhead.
2. Check the printhead harness.
3. Check the printhead itself and replace if necessary.
EVALUATION OF THE CONTROL BOARD ASSY.
The following status codes indicate the Control Board Assembly has a fault.
900 RAM Test Failure 905 Illegal Interrupt
901 ROM/EPROM Test Failure 906 Power Failure
902 Timer Failure 907 No Application Memory
903 Interrupt Test Failure 908 NVRAM Checksum Failure
904 No Kernel Memory 910 Warm Restart
1. To determine if this fault is permanent or temporary, turn the printer off, wait 15 seconds then turn the printer on
again. If any of these status codes are repeated, turn off the printer and replace the Control Board Assy.
2. Print a test label. See Test Label (Level 1), in Chapter 4, for instructions on printing a test label.
3. Place the printer in Data Dump mode and send data to the printer.
EVALUATION OF COMMUNICATIONS
If the printer functions properly off-line, examine communications. There are two communication paths for the
printer. The RS-232 serial path uses a 25 position connector. The IEEE-1284 parallel path consists of an external
36 position connector, CN1, and an internal 40 position connector, CN5, that is used to support the Coax/TwinAx
Interface. CN1 also supports an external Ethernet adapter.
14 TC9830SM Rev. B 7/98 Confidential July 1998
Troubleshooting 9820/9830/9835 Service Manual
The external Coax/TwinAx Interface is a 15 position connector into which is plugged either a Coax adapter cable or a
TwinAx adapter cable. (All electronic activity for the serial port is limited to the Control Board Assembly. All
electronic activity through CN1 is limited to the Control Board Assy.) There is a small circuit board mounted on the
inside rear printer wall that interconnects the 15 position external connector with the internal CN5. Both CN1 and
CN5 share common PCB electronics.
1. Make sure the printer is plugged in and connected to a host with the proper cables. See Connecting to a Host,
in Chapter 1.
2. Compare host communication values to values reported on the test label. See Test Label (Level 1), in Chapter
4, for instructions on printing a test label.
3. Check printer ports using SENDFILE to send an ENQ.
GENERAL TROUBLESHOOTING SUGGESTIONS
There are a number of printer self-reporting fault detection/fault isolation avenues built into the 9820/9830/9835
printers. Three digit status codes, detailed in Appendix A, all help to pinpoint the problem. In addition, the printer
provides status information in the two test labels, in the SENDFILE service diagnostics tests, and in information
