Introduction

The GA42 is a rugged and simple to operate dot matrix printer for METTLER TOLEDO titrators, pH meters, density meters, refractometers, and melting point
apparatus, as well as for METTLER TOLEDO balances with an RS232C interface (balance lines: AB, B, PB, CB, GB, PG-S). The printout on normal paper fulfills
the requirements of modern quality assurance systems (GLP, GMP, ISO 9000, etc.). These define, among other things, the principles and duties for the user
of measuring instruments or inspection, measuring and test equipment. The GA42 complies with the principle of traceability of measurements by precisely
documenting the origin of data, as well as calibration procedures. It fulfills the obligation to archive measurement results by its chemically resistant, thermally
stable and lightfast print. On connection to METTLER TOLEDO balances, the GA42 prints all data sent by the balance without restriction, that is not only weight
values and calibration procedures, but also the results of all applications, such as piece counting, built into the balance.

Safety measures

The GA42 has been tested for the connections and intended purposes documented in these Operating Instructions. However, this does not absolve you from the
responsibility of performing your own tests of the product supplied by us regarding its suitability for the methods and purposes you intend to use it for. You
should therefore observe the following safety measures.

Risk of electric shock

Risk of explosion

Caution

– Never open the housing of the printer yourself! Have the printer serviced only by METTLER TOLEDO service!

– Never work in an environment subject to explosion hazards! The housing of the instrument is not gas tight (explosion hazard due

to spark formation, corrosion caused by the ingress of gases).

– Wipe off splashed liquid immediately! The printer housing is not watertight.
– Follow the cleaning instructions on page 7!

Configuring the interface

• Open cover of paper compartment (1) and remove paper roll.

• Press plastic tab (2) backward and open the battery compartment cover.

• Leave DIP switch 1 in the OFF position! It has no meaning.

• Set DIP switch 2 of the printer accordingly.

Startup procedure

Inserting paper

• Feed paper through the slot in the printing unit in the direction of the arrow.

• Switch on printer with toggle switch at the rear.

• Press and hold until sufficient paper has been fed in.

Attaching the printer

• Attach connection cable of the GA42 to the printer interface of the instrument and to the printer.
After configuring the attached instrument for the GA42, the printer is ready for operation.
Order numbers for connection cables, see page 7.

Printer test

The GA42 is equipped with a self-test which automatically prints out the character set of the printer.

Starting the test

• Switch on GA42 and at the same time press and hold for a few seconds.

Terminating the test

• Switch off the GA42.

• Pressing the printer key advances the paper 1 line (line feed).

On connection of the GA42 to METTLER TOLEDO balances:

• Pressing the balance key with the symbol prints out the stable weight value.
As long as the balance does not show a stable weight value, nothing will be printed out.
With PR- and SR-balances, an automatic printout is possible. The printout includes weight with time, date and sample number.

Changing paper

• Insertion of a new roll of paper is described on page 4.
Order number for paper, see page 7.

Replacing the ribbon

• Pull paper out of printing unit (1).

• Remove ribbon cover (2, 3, 4).

• To remove ribbon cartridge, press in direction of arrow (5).

• Insert new ribbon and if need be, take up slack with tensioning wheel (6).

• Refit ribbon cover.

• Insert paper and feed through slit in the printing unit as far as it will go.

• Press and hold until sufficient paper has been fed in.

Maintenance
