for the 1755 Printer

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

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.

specified voltage and complete the power connection to
the DC input connector at the rear of the printer, located

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
