2 FUNCTIONAL DESCRIPTION
The printer chassis is made up of a lower module containing the printer control board and
an upper module containing the mechanical functions.
Figure 3. Printer design
The printer has three motors controlled by the application software. All sensors are
reflector-type opto-sensors except the printhead-up sensor that is a micro switch.

TTP 5000 Series Kiosk Printer Sub-system — Service Manual Edition B, May 978
2.1 Paper handling
The print module has a stepper-motor that drives a platen. The thermal printhead
presses against the platen with the temperature sensitive paper in-between. The platen
pulls the paper from the supply roll and feeds the paper through the cutter module and
up to a couple of feed rolls in the presenter module. The rolls are driven by the presenter
motor (DC-motor).
During the printing procedure, the application program runs the presenter motor slowly
until the presenter sensor detects the leading paper edge. The top of the document is
then arrested by the presenter feed rolls. Deflection ribs in the presenter module assist in
forming a document loop within the printer if the application program postpones the
ejection until printing and cutting is completed. The presenter motor will then eject the
document. If so selected by the application program, the presenter feed rolls can be set
at continuous feed-through during printing, for example, when very long documents are
being printed.
The presenter sensor also detects when the trailing document edge leaves the exit slot.
The combined paper-end and TOF sensor is actuated by light reflection against the back
of the paper. If the light reflection disappears, but returns within a specified number of
paper-feed motor steps, this means that a pre-printed black mark is detected. If the light
does not return before this number of motor steps has been effected, this will be
interpreted as paper end.

Edition B, May 97 TTP 5000 Series Kiosk Printer Sub-system — Service Manual 9
2.2 Paper near-end detection
Both the standard paper roll holder (see Figure 3) and the optional holder for up to
200 mm diameter paper rolls (see Figure 4) have an optical reflection sensor that
becomes actuated when there is about 3 m paper left.
In addition, the optional paper roll holder has an adjustable paper level monitor that can
be used, for example, to decide whether or not the remaining paper will last during a
weekend.
Figure 4. Paper sensors on roll holder for 200 mm diameter rolls (optional)
2.3 Paper jam detection
The length of each document is known by the application program. If the presenter
sensor does not detect the leading edge of a document when expected, this will be
interpreted as if paper jam has occurred. Paper jam error will also be signaled if the
presenter sensor detects paper in unexpected situations.

TTP 5000 Series Kiosk Printer Sub-system — Service Manual Edition B, May 9710
2.4 Cutting
The cutter module moves the cutting knife first down (cutting) and then up again by
means of a DC-motor and a crank mechanism. A sensor detects when the knife reaches
its upper (home) position.
A vertical leaf spring (not shown in the above figure) aids in keeping the free end of the
movable knife blade pressed against the fixed cutting edge.
WARNING!
DANGER OF INJURY! Depending on the position of the crank mechanism, the cutting
knife may start moving when the printer is switched ON. KEEP HANDS AWAY WHEN
SWITCHING ON THE PRINTER.
2.5 Printhead-up detection
Lowering the paper release lever separates the printhead from the platen and actuates
the printhead-up micro-switch sensor. This sets a status bit in the status message.
Printing is interrupted as long as the printhead is lifted.
Lowering the paper release lever is also part of the procedure for setting the printer in a
HEX dump mode for logging the data transfer between the host and the printer. See
page 15.
CAUTION! — if the printer is not going to be used for a week or more, disengage the
printhead from the platen by lowering the paper release lever. Both the printhead and the
platen can otherwise be deformed.

Edition B, May 97 TTP 5000 Series Kiosk Printer Sub-system — Service Manual 11
2.6 Electronics
Also see logic diagrams in Chapter 5.
2.6.1 Micro processor system
The control board 492-00 is equipped with an 8031 microprocessor whereas the 728-xxx
control boards are based on an 80C320 microprocessor, an enhanced version of the
80C32 processor. Printers with the 728-xxx board meet the EMC directives for CE
marking.
2.6.2 Static RAM
The control board has 128 or 256 Kbyte static RAM used for buffering of graphics data
during printing. The 256 Kbyte capacity used in TTP 5200 and 5250 allows full landscape
printing (210 mm) whereas the 128 Kbyte RAM used in the TTP 5000 and 5100 gives
restricted landscape printing capabilities.
2.6.3 PROM
The control board is equipped with an EPROM or flash PROM capsule holding the printer
firmware, character font sets, character parameters, etc. The flash PROM allows online
downloading of its contents.
2.6.4 Printing
The control board controls the printing. TTP 5000 and 5100 have two standard character
font sets installed whereas TTP 5200 and 5250 have four. Each font can be printed in
standard size, double width, double height and quadruple size, in both portrait and
landscape modes, and as black on white background or the reverse. With TTP 5100,
5200, and 5250 you can also use the underlining font attribute.
Bar code printing is available as well as bit map graphics. The near-paper-end sensor is
actuated when there is 2—4 m left on the paper roll. The paper end & TOF sensor
(reflector sensor) inhibits printing if there is no paper at all in the printer module.
Print speed and paper transport speed is approximately 50 mm per second.
2.6.5 Cutting
The DC-motor first turns in one direction to perform the cutting. The cam on the cam
wheel actuates the cutter-home sensor when the mechanism reaches its home position
again. At this moment, the motor is forced to a quick stop as the drive circuit for turning
the motor in the opposite direction is activated momentarily.
2.6.6 Communications interface
The control board used in TTP 5100, -5200, and -5250 has both serial and parallel
interface ribbon cable-type connectors.
The TTP 5000 control board has only a serial interface connector of the same type, but
there is an optional parallel interface piggy back board (SWC-651-000) that should be
mounted on top of the control board when this type of interface is required.

TTP 5000 Series Kiosk Printer Sub-system — Service Manual Edition B, May 9712
To be able to connect the printer to the host using a standard serial or parallel printer
cable, there are two adapter cables available. The outer end of either cable can be fixed
attached to the paper roll holder frame.
TTP 5000 SERIAL INTERFACE
The serial interface is a standard RS232C (V.24) interface with 8 data bits, 1 start bit, 1
stop bit and NO parity.
The SWC 492-000 control board has DIP-switches (SW1) for setting of some
communication parameters.

2.6.7 Power supply
TTP 5000/5100/5200 require +24VDC ±5% and +5V ±5% VDC input.
The TTP 5250 requires +24VDC ±5% only.
Current consumption during character printing is 2 A average, and 6 A at peaks. The
consumption during all-black, and dense, printing is 6 A average and 10 A at peaks.

TTP 5000 Series Kiosk Printer Sub-system — Service Manual Edition B, May 9714
3 MAINTENANCE
3.1 Fault finding
In connection with service of the printer system, it is good practice to clean the printer
mechanism in order to remove paper dust and lint from the paper path, cutter and sensor
areas. Paper dust, when accumulated, may interfere with printer functions such as
reflector sensors.
Do not apply oil on the cutter edges since this might smudge the paper.
The printer informs the host of some error symptoms by means of status reports and
error codes. See TTP 5200/5250 Installation Manual.
Symptom Suggested actions
Strange paper feed behavior . • Check that the presenter sensor is not
affected by excessive ambient light from
above or through the front opening.
Printing does not stop at paper out. • Check that the paper-out/TOF sensor is not
affected by excessive ambient light.
Nothing is printed when you keep the form-
feed button depressed while switching the
printer ON, but the document is transported,
cut and ejected.
• Check that the paper roll is turned with the
temperature-sensitive side facing up.
• Check that the paper meets the paper
specification. *)
• Check that the ribbon cable connector at the
top of the print module is fully inserted.
Test document can be produced as
described above, but the printer works
strangely in normal operation.
• Check that both ends of the data cable are
properly connected.
• Application program might be incorrect, for
example, with respect to handshaking.
Contact system manager.
• Make a HEX dump printout and check
incoming data string. See page 15.
Printing gets interrupted • Check if printer is out of paper.
• Check if there is any paper jam.
• Check that the presenter sensor is not
blocked by paper dust or pieces of paper.
• Check function of presenter sensor.
• Check that the printer is properly connected
to protective earth. This is to prevent earth
currents between printer and host, but also to
prevent electro-static discharges.

Edition B, May 97 TTP 5000 Series Kiosk Printer Sub-system — Service Manual 15
Symptom Suggested actions
Printer does not work at all • Check that the paper release lever is in
vertical position (print head presses against
the paper).
• Check for paper jam between print module
and cutter. If cutter is not in home position,
check function of cutter home switch.
• Red and green voltage indicator lamps
should be ON (visible from the rear of the
printer).
If both lamps are OFF, check that the power
cable is connected at both ends and that the
power supply is switched ON. Check line
voltage supply fuses.
If only the red lamp is OFF, replace the PCB.
No cutting • Check that the connector for the cutter motor
and the cutter home sensor is fully seated on
the control board.
Bad cutting (uneven top and bottom
document edges) • Switch OFF, remove any obstructing paper
particles in cutter and presenter modules.
Missing print or irregular spots • Paper may be too humid. Let the paper
adapt to ambient temperature and humidity
for approximately 24 hours before use.
• The paper used might not meet the paper
specification. *)
White longitudinal lines in the printout • Clean printhead with isopropyl alcohol.
• Replace print module.
Faint print • The paper used might not meet the paper
specification. *)
• Clean printhead with isopropyl alcohol.
Strange characters or graphics printed, or
any kind of strange printer behavior. • Might be caused by erroneous data sent
from the host. Check validity of transferred
data by using the hex dump test function
described below.
• Check setting of transmission speed and
parity.
*)See applicable installation manual regarding paper specification.
Use the following procedure to set the printer in HEX dump mode:
1. Switch OFF the printer.
2. Lower the paper release lever.
3. Keep the form feed button depressed while you switch the printer ON again.

TTP 5000 Series Kiosk Printer Sub-system — Service Manual Edition B, May 9716
4. Raise the paper release lever. Until you switch OFF the printer, it will present all
transferred data both in hexadecimal notation and as ASCII characters in two
adjacent columns containing 8 bytes each. The printout is formatted for 60 mm page
width.
Switching the printer OFF and ON again resets it to normal operating mode.
3.2 Parts removal and replacement
WARNING!
DANGER OF INJURY! Depending on the position of the crank mechanism in the cutting
module, the cutting knife may start moving when the printer is switched ON.
KEEP HANDS AWAY!
CAUTION!
The printer power supply should be switched off, and the low-voltage power cable should
be disconnected from the control board before you disconnect or connect any other cable
on the control board. The printer electronics might otherwise be damaged.
CAUTION!
The printhead and some components on the control board are sensitive to ESD
(electrostatic discharges). To prevent damaging such components, observe all the usual
precautions such as keeping the part in its original packing (“ESD-bag”) until you are
ready to install the part. Do not touch its pins. Use a grounded wrist strap when handling
ESD-sensitive components.
CAUTION!
If the printer or print module is not to be used for a week or so, disengage the printhead
from the platen by lowering the paper release lever. Otherwise, both the printhead and
the platen can be deformed.
