1.1 INTRODUCTION
This section gives you all the necessary informations to maintaine the DC power supply module. It also
specify how to modify the printer to operate on DC supply instead of AC supply.
1.2 PRINCIPLE OF OPERATION
The power supply module is constructed to operate from a battery voltage of 10.5V DC to 32V DC to
deliver the necessary voltages for the printer. The voltage conversion takes place in a “flyback” switch
converter, which is controlled by a current mode controller. The regulation of the output voltage is
controlled via a separate winding of the transformer, which also deliveres the power for the control circuit.
At the input and at the output are placed filters to suppress the switch noise.

2.2
DISASSEMBLING AND MOUNTING OF THE ON-OFF SWITCH
It is necessary to remove the ON-OFF switch from the transformer assembly to use it again on the DC
power supply module.
Remove the filter and switch board from the transformer by pulling it off.
Unsolder the ON-OFF Switch.
Solder the switch to the two loose wires on the DC power supply module. Then twist the wires to the switch
to suppress noise.

MOUNTING THE DC POWER SUPPLY AND REASSEMBLING
Remove the cover on the glue pad and when the power supply module is placed properly, the switch is
placed in the slots in the cabinet and is pressed down to the glue pad.
Ground connection is
mounted under the
mounting frame
The mounting frame is
fixed with the two
screws from the
mains transformer
28556
DC power supply circuit board is fixed
to the mounting frame with four screws
The ON-OFF Switch is placed
in the printer panel cutout and
fixed to the PCB with a glue pad
28557
Note: Remove the
" 220V ~ " label
2.3.1
MOUNTING OF THE DC POWER SUPPLY
Place the ground connection over the rear transformer hole, and fix it with the ground screw.
Place the mounting frame where the transformer was mounted, and fix it with the two screws from the
transformer.
Then place the DC power supply module on the mounting frame, and fix it with four screws.
Be sure the power ON-OFF switch is correctly placed in the panel cut out slot.
Press the plate with the DC input connector in to the panel cut out the formen AC cord receptable.
Connect the output cable to the printer Main Control Board.

2.3.2
PART II/H1252B
MODIFICATION OF THE PRINTER MAIN CONTROL BOARD
If the printer is equipt with a DC power supply module of other type than from ECI, it is necessary to
modify the printer main board. As seen below, the diode D28 (D10) on the printer main board is short
circuited.
If the printer is equipt with a DC power supply module from ECI, module no. 628471 it is not
recommended to short circuit the diode D28 (D10) on the printer main board.
Run the printer selftest programme.
Switch on the ON-OFF switch and simultaneously press down the “line feed” button.
After a few seconds (at low input voltage) the printer starts the selftest printing routine, which means
that the DC power supply is OK.
Switch off the printer.

REASSEMBLING OF THE PRINTER
Place the top cover by lifting the front end and place holes in the rear end into the two small hooks in
the bottom cabinet.
To reassemble the printer, do the reverse procedure of the disassembling.
Then run the selftest programme of the printer. (See above)

After a few seconds (at low input voltage) the printer starts the selftest a printing routine, which means
that the power supply is OK.

5 CIRCUIT DESCRIPTION
5.1 DC POWER SUPPLY
To suppress noise on the supply wires a filter is build around the current compensated choke L1.
Furthermore the RC snubbers across the transformer prevent unwanted oscillations during transition
time. The diode D7 in conjunction with R16 and C19 clamps the transient voltage spikes across the
switch transistor Q1.
When the supply is switched on, the capacitor C6 is charged by means of R1 and when the voltage
exceeds approx. 8.7V the controller U1 turns on. After a few cycles power is delivered from the
bootstrap winding of the transformer to maintain the supply to the controller U1. When switching of the
supply voltage, the power from the transformer disappears. This means the supply voltage to U1
decreases to approx. 7.6V and the controller U1 switches off.
The rectified voltage from the bootstrap winding is also used to regulate the output voltages, which
mainly is determined by R8 and R11. The feedback voltage is led to U1 pin 2. The resistors R10 and
R9 and the capacitor C17 form the compensating circuit for the voltage regulation.
The controller is working at a fixed frequency of approx. 100 kHz, determined by R7 and C16.
The switch current is sensed by R15 and led to U1 pin 3 after being filtered by R14 and C18. The current
sense voltage is a ramp voltage, which is compared to a DC level determined by the voltage regulation
circuit. When the ramp exceeds the DC level, the controller U1 switch off the FET Q1. This current
sense circuit forms a current regulation loop, which is stabilizing the over all regulation and prevents
high current to damage the switch transistor Q1.
When Q1 is on, the output diodes D3 and D4 is reversed biased and current to the load is delivered from
the capacitors C12 and C13. During the off time of Q1, the transformer outputs deliver the currents to
the capacitors C12 and C13 and to the load.
The chokes L2 and L3 are parts of lowpass filters to suppress voltage spikes.
Because of the converter principle , which is a ringing choke flyback type, without direct feedback from
the output the voltages, the output voltages are load dependent.
At input voltage under approx. 15V and at full load, the converter "changes frequency" and gets an
irregular duty-cycle. That is normal behaviour.
At low input voltage the start up time can be as long as 4 seconds, depending on the load.
