Parr Instrument 1755 - Manual

SCOPE
These instructions cover the installation and use of a
Parr 1755 Printer with any of the Parr calorimeters and
other apparatus listed in the table below. It supplements
the detailed instructions provided in the 50-page Star
Micronics User’s Manual for DP8340 Series, Dot Matrix
Printers which is furnished with each printer.
PRINTER IDENTIFICATION
The 1755 Printer is a serial, 40-column, dot matrix
printer which operates on 12 volts DC. Power for the
printer is drawn from a separate power supply which can
be plugged directly into an AC line. For applications such
as the Parr 1271 and 1281 Calorimeters and the 1760
Sulfur Analyzer, where 12 volts DC can be drawn from
the unit being served, Parr furnishes a 1756 Printer
which is the same as 1755, but without a separate power
supply. Instructions for the 1756 Printer are included in
the operating manual for the apparatus with which the
printer is used.
INSTALLATION
The printer and power module are packed separately for
convenience in shipping. Unpack these units carefully
and check to be sure all parts are provided, as shown on
page 2 in the User’s Manual.
Be sure all devices are turned off before making any
power connections.
Connect the power module to an AC outlet of the
specified voltage and complete the power connection to
the DC input connector at the rear of the printer, located
as shown on page 6.
Install the paper holders and the re-roll prevention wire
as shown on pages 3 and 4. Note that the paper holder
is to be attached to the outmost holes at the rear of the
printer with the round hubs facing each other. Install the
paper roll as instructed on page 10.
After inserting the paper in the feed slot, turn the power
ON and hold the feed button down until paper emerges
through the paper outlet.
CAUTION: Always use the feed button to advance the
paper.
DO NOT PULL THE PAPER BACKWARDS FROM
THE REAR OF THE PRINTER. The printer motor turns
only on one direction. If the paper is pulled from the back
of the printer, the pinion gear will be stripped.
Lift the printer cover to see that an ink ribbon is in place
before attempting to operate the printer. Do not print
when there is no ribbon or paper put into the unit. To do
so will damage the print head.
CABLE CONNECTION
Connect the printer to the unit being served using the
cable listed in the table below. Note that several devices
do not require the adapter block which is attached to the
end of the A962E cable. The block must be removed
when making the connection to these units.
