2. Description
2.1 Printer Overview
The MP- 2005 Mobile Printer is a ruggedized dot matrix
printer designed specically for mobile and portable ap-
plications. It can print in graphics mode along with diffe-
rent character fonts, both in draft ( 150 cps ) and NLQ (
25 cps ) mode. It has both tractor and friction feed me-
chanisms and can print on multi-copy paper
( 1 original and up to 3 copies ).
MP- 2005 is particularly suited for in vehicle applications,
due to its compact size and reduced weight. Power re-
quirements have been kept to a minimum bij means of
two DC motors with integrated optical encoders, and an
integrated driver board for precise positioning rather than
stepping motors.
MP- 2005 has a 2 Kbytes input buffer and comes with
an RS-232 serial interface. The MP 2000 driver software
supports DOS, Windows NT, Windows ‘95 and is compa-
tible to the commandset of EPSON LX 400/800.

4. Installation
4.1 Unpacking
Take the printer out of its shipping box and remove any
packing material. It is advisable to keep the shipping box
in case the printer needs to be reshipped or stored
elsewhere.
4.2 Procedure for Installation
4.2.1Mechanical installation
The MP-2005 can print in any position
4.2.2 Driver installation
MP-2005 driver software supports DOS, Windows NT,
Windows ‘95 and is EPSON LX 400/LX 800 compatible
and it can therefore be congured as such in the majority
of the software packages.

4.3 Printer Setup
The MP-2005 can be congured by using the DIP-swit-
ches as shown in Fig. 1. The function of the DIP-switches
is depicted in Table 1.
TABLE 1 - DIP SWITCHES
Dip Switch Function
SW 1-1 Baud rate (see Table 2)
SW 1-2 Baud rate (see Table 2)
SW 1-3 for serial interface:
ON=XON/XOFF mode
OFF=DTR/DSR mode
SW 1-4 Character set
SW 1-5 Character set
SW 1-6 Character set
SW 1-7 CRLF mode: ON = enabled
OFF = disabled
SW 1-8 STAND-BY mode: ON = enabled
OFF = disabled
NOTE: Standard factory setting: SW 4,5,6, ON.
TABLE 2 - BAUD RATE SELECTION
Baud Rate SW 1-1 SW 1-2
1200 ON ON
2400 OFF ON
4800 ON OFF
9600 OFF OFF
CRLF mode = ON means that after every CR character
(carriage return) sent by the host, the printer automati-
cally performs a LF (Line Feed)
operation.
STAND-BY mode = ON means that after a certain pre-set
inactivity period, the printer goes to stand-by mode (re-
duced power drain).
If DIP-switch setting is switched ON while the printer is
on, the new conguration will come into effect only after
a subsequent printer turn-off and turn-on cycle.

4.4 Caution!
* Do Not print without inked ribbon or paper, since this
leads to rapid printhead needle wear- out.
* Do Not move the printhead manually.
* Avoid mechanical shocks.
* Before starting to print, check that the inked ribbon
cartridge is correctly installed, the paper is loaded in the
proper position and the printer’s upper swiveling part is
locked to the lower one.
* If the printer has worked for some time, avoid touching
the printhead: it can be very hot. It is advisable to wait a
few minutes before attempting to replace the inked rib-
bon cartridge.
* Once the printer has been turned off, wait at least 10
seconds before turning it on again; this allows the inter-
nal reset circuitry to work properly.
* Do Not open the printer when it is operating.
NOTICE
Turn the computer on before the printer and turn the
printer off before the computer. This is only to avoid
dummy data to be sent by the computer printer du-
ring the on/off sequence.
NOTE:
The small size of the printhead did not allow for a
headpaper spacing adjustment device to be used in
single-copy or multi copy printing. Therefore, when
multi-copy printing is performed with a freshly in-
stalled inked ribbon cartridge, the rst printed pages
may have some ribbon marks.
4.5 Self Test
The printer is able to perform an internal self-check routi-
ne followed by a self-test printout.
To execute this procedure, simply keep the LINE feed
push-button pressed while the printer is powered up. The
test procedure prints a rst page with general information
about the MP-2005 and a second page of fonts.
CAUTION
DO NOT SELF TEST WITHOUT INKRIBBON OR PAPER.

4.6 Indicators
POWER ON
This indicator lights when the printer is correctly powe-
red.
ON LINE
Turns on when the printer is ready to accept data. If the
ON LINE indicator ashes, the printer has switched to
STAND- BY mode.
PAPER END
Comes on when the printer is out of paper.
4.7 Alarm and Indicator Functions
The following description assumes that the control panel
with associated indicators and alarm is connected to the
printer.
ERROR indicator ashes
This means that the motor is locked due to some mecha-
nical reason; it is recommended to turn the printer off to
avoid battery pack overcharging.
5. Printer Operation
The MP-2005 control panel is tted with four control
keys, three indicators of which one is an alarm indicator.
5.1 Control Keys
This key switches the printer on and off. When ON LINE,
the printer is ready to accept data from the computer.
Likewise when it is switched OFF LINE, the carriage auto-
matically moves to the center of the printer span. When
ON LINE the printer ignores the remaining push-buttons.
If the printer is switched ON LINE when the LINE FEED
push-button is activated, a demonstration test is perfor-
med.
ONLINE Paper End Error
This key advances the paper by one
sheet length (i.e. to the beginning of next
page).
This key advances the paper by one line.
This key retracts the paper by one line.

5.2 Power Source
The MP-2005 requires a power source between:
* 11.0 - 14,0 VDC
* If the voltage drops below 10.5 VDC
( batteries drained ) the printer stops.

5.3 Paper Loading
MP-2005 can print on UNI A4/A5 size single sheet paper
forms or multi part paper forms or continuous fan-fold
paper with hole to hole spacing of 227mm (8.94”).
The procedure for correct paper loading is the following:
● Set the printer OFF LINE
● Open the printer by lifting lever A (Fig. 2.)
● Insert single-sheet module by placing it over the
printing plate, while checking if it is equally spaced
with respect to the printing area; in case of
continuous fan-fold paper, be sure that the
sprockets engage correctly in the holes provided for
near the edges.(see photo A,B and C)
● Close the swiveling printer top.(see photo D)
● Switch the printer ON LINE again.

CAUTION
If the printer has been printing for some time it is ad-
visable not to touch the printhead during paper loading or
inkribbon cartridge replacement, as it could be very hot.
5.4 Sensors
A reective sensor is used on MP-2005 for determining
the PAPER END condition. When this sensor detects the
end of the currently printed sheet, the following actions
take place:
1. printing stops.
2. the printer switches to OFF LINE
(ON LINE indicators goes off).
3. PE (PAPER END) indicators comes on.
4. carriage moves to middle of the printer span.
In order to resume printing, a new sheet should be loa-
ded and the ON LINE pushbutton should be pressed
The PAPER END sensor is also used to detect an “open
mechanism” condition. When the mechanism is open, the
sensor no longer sees the sheet and actions described
above take place. The carriage is likewise moved to the
center until a new sheet is introduced, the printer mecha-
nism is closed and the ON LINE push-button is pressed.
5.5 Maintenance
The MP 2005 does not require special maintenance, ex-
cept for the following:
-periodic cleaning, approximately every 10 million charac-
ters, of the printhead bearing rod with isopropylic alcohol
or similar.
- verication of the distance between printhead and prin-
ting plate (if the printer has suffered major shock or whe-
never an appreciable occurrence of bad quality printing
is experienced). The distance, measured by a thickness
gauge with the printer closed and no inked ribbon inter-
posed, should be 0.55 mm +/- 0.05 mm.
-periodic cleaning of the printer’s mechanism, in order to
avoid dust particles, paper clips and the like, can cause
mechanism malfunctions.

5.6 Inked Ribbon Cartridge Installation and
Replacement
Cartridge installation/replacement procedure:
● Turn the printer off.
● Remove used cartridge by unlocking bottom latch
and then rotating cartridge body upwards as shown
by arrow D.
● Place ribbon extender on both studs B until it locks
down, paying attention to the ribbon not
disengaging from the extender itself.
● Gently move the cartridge body along the printing
axis and seat it down on its holder C; the ribbon
should be made to enter partly in the gap between
the steel-wire ribbon holder and the printhead
nose.
● Stretch the inked ribbon by turning knob A
counter-clockwise. Turn the printer on without
loading any paper; make sure that after the
switch-on side movement of the printhead, the
ribbon is properly positioned under printhead’s
nose.
