RS 244-632 User manual

Installation
Precautions
1. The printer is to be used free-standing and should be
placed on a stable surface providing easy access to the
control panel and to the paper well when the lid is open.
2. Do not site the printer in an excessively hot or humid
location. Exposure to grease, dust, metal swarf or liquids is
best avoided.
3. When using the power adaptor avoid using a mains outlet
which also supplies heavy switching machinery since a
noisy supply may impair printer operation.
4. Ensure that the adaptor provides the correct operating
voltage. (See specification at the end of this instruction
leaflet).
5. Care must be taken to ensure that any power adaptor used
meets with national safety requirements and has the
correct output voltage and polarity. Recommendation is
given for RS stock no. 244-654.
6. Do not remove paper by pulling it from the back of the
mechanism and do not pull excessive lengths through the
top of the mechanism. Either of these operations may
cause paper to tear and jam the mechanism.
Default settings
The printer is supplied with the following default settings:
Data bits 8
Parity None
Baud rate 9600
Character set UK
Print mode Text
Auto-off 5 min
Emulation Standard
DTR Normal
Interface Serial
Mechanism As applicable
Default settings can be restored by pressing both the feed and
programme switches together at power up. Releasing the feed
button before the programme button will set original defaults.
Self test
To perform a self test press the power on and feed switch
simultaneously and keep depressed until the test starts. This
will check all the mechanics, and a large proportion of the
software and hardware without the need for connection to a
host. The software issue is printed in double height, double
width text, followed by the character set in normal text. Below
this are listed the current settings of the user selectable
options. If the settings are correct for your host, you are ready
to connect the printer to your system. The self test will be
repeated until the power is switched off. Normal operation is
resumed after power on.
Interface connection
The printers are available with an RS232 serial interface.
The interface type is printed on the self test slip.
The connector is a 25-way D socket for serial interface.
Programme mode
On the front of the unit there is a power on indicator and four
switches which are labelled on the panel from left to right,
RS programme, paper feed, on and off.
If the programme switch is pressed at power up (ie. programme
switch and power on switch together) then the printer will go
into set up mode and print the current parameter status.
Example: Number of data bits: 8-bit data.
The power on indicator will flash every second to indicate
programme mode.
Each time the feed switch is pressed and released the next
printer parameter is printed. Pressing the programme switch
will cause the status of that parameter to change in the
sequence shown. Each status table rotates so 300 baud
follows on from 19200 baud and so on.
Once the correct status has been selected then both the
programme switch and the feed switch should be pressed
simultaneously to update the printer status. Note that this need
only be done when all parameters that need changing have
been selected. If no switches are pressed for 15 seconds the
set up mode is automatically terminated without changing the
original parameters.

An alternative method is to send the 'set up' data via the RS232
port to prevent the need for manual programming.
Set up via data interface
If the unit is turned on whilst both the programme and feed
switches are pressed and only the programme switch is
released, the unit will print:-
"NVR COMMS READY>"
At this point the printer is waiting to receive data in the following
format:
"PROGRAMME-MODE" + CARRIAGE RETURN + n1 + ...n10
(n1 to n10 are hex numbers).
The "PROGRAMME-MODE" followed by a carriage return
indicates that the printer should expect parameter data as
shown in table 1. Upon receiving information in the correct
format the unit will print:
"DATA OK, NVR UPDATED!"
If the data received is not in the correct format then the unit will
print:
"DATA ERROR NVR UNCHANGED"
Note: If no data is received within 15 seconds or the feed key
is released before the procedure is complete, then the
change of parameters will not take place and the unit will
print:
"SET ERROR NVR UNCHANGED"
SET UP COMMAND PROTOCOL

The programme sets: 7 data, odd parity, 4800 baud, France,
Data mode, 1 min., 560, NORMAL DTR, zero with a "slash"
across it.
Note: The factory defaults can always be restored by pressing
both the feed and programme switches at power up then
releasing only the feed switch. Defaults will be restored
and a printed message acknowledges that this has
occurred.
Operators guide
Operation
* DO read the operating instructions carefully before you attempt
to use the printer.
*DO ensure that any electrical connections are properly made
in accordance with the instructions.
*DO NOT remove any fixed covers unless you are qualified to
do so and even then switch off first and disconnect the power
adaptor from the socket before you start.
*DO NOT continue to operate the printer if you have any doubt
about it working normally, or if it is damaged in any way. Refer
the unit for repair.
Power on procedure
Check the batteries are sufficiently charged or that the power
adaptor is connected correctly.
Open the lid and check that paper and ribbon are present, and
that there are no foreign objects inside the paper well or
mechanism.
Close the lid, ensuring the paper is guided out through the paper
exit slot.
Switch on the printer by pressing the symbol marked 'I' on the
switch panel.

The power on indicator will light and the mechanism will reset.
Paper loading
If the paper roll needs replacing adhere to the following
procedure.
Open the lid and remove the old paper, taking care not to pull the
paper out of the back of the mechanism. Press the feed switch
until any excess paper left in the mechanism is fed out.
Reel off a few centimetres from a new paper roll and ensure that
the paper end is square.
Sit the paper roll in the paper well with the paper end coming from
the bottom of the roll.
Offer the paper into the back of the mechanism and press the
feed switch. Keep switch depressed until enough paper is fed
through the mechanism to be inserted through the paper exit slot.
Feed the paper through the exit slot and close the lid.
Ribbon change
Ensure the power is off and open the lid. The legend on the
cassette gives an instruction (PUSH) to remove the old ribbon.
The cassette will clip off one side and can easily be removed
Take a new ribbon and check it is taut. Clip it into position
making sure that the paper protruding from the top of the
mechanism is located between the exposed ribbon and the
plastic cassette. Wind the knob a few turns in the direction
shown on the cassette to take up any slack in the ribbon.
Close the lid
Paper feed
Check the power is on.
For a single line paper feed, press and release the feed switch.
For continuous line feed keep the switch depressed.
Note: The power indicator will turn off when the feed switch is
depressed.
Care of the printer
Periodic cleaning will help to keep your printer in good condition.
IMPORTANT: Switch the printer off and disconnect the power
adaptor before any cleaning operation.
Use a soft brush to remove any dust or foreign particles from the
paper well and mechanism. The case may be cleaned with a soft
cloth slightly dampened with alcohol. Be careful not to let any
liquid enter the printer enclosure.
Do not use the printer if liquid or metal objects have entered the
unit. If this happens whilst the printer is in use, switch off
immediately and have it serviced.
If the printer is not going to be used for some time disconnect the
power adaptor and ensure the unit is switched off.
Do not continue printing with a worn ribbon, since this will
eventually fray and may damage the print head.
Do not leave the printer powered up if it is malfunctioning.
Note: To conserve the battery power ensure that the unit is set
at 1 or 5 minute auto off.
