2 Unpacking

Delivery includes:

1 - Printer 2 – Power supply unit 3 – Printer cable 4 - 1 x Roll of thermal paper 5 – Operating instructions

If one the articles listed above is missing please contact your supplier immediately.

3 Installation and commissioning

Environmental conditions at the workplace chosen for the printer must meet the conditions stated below:

Temperature: 5°C – 35°C Humidity: 10 – 80 % (excl. condensation)

Take notice of the following as regards to the site of operation:

Dust and humidity free Do not place printer next to powerful sources of heat Do not place the device within range of strong electric, magnetic, electromagnetic impulse fields or planes that collect electrostatic charge. Do not expose printer to direct sunlight or impacts.

Power is supplied via the external mains adapter. The stated voltage value must be the same as the local voltage. Only use original KERN mains adapters. Using other makes requires consent by KERN.

Changes to the settings for the micro switches must be made with the power supply turned off. The changes are taken over when started-up again.

Connecting the cables:

There are two interfaces at the back wall of the housing:

Terminal printer cable Terminal power supply unit

Always use KERN accessories and weighing balances when working with your printer. Disconnect the printer from the mains voltage before connecting the cable to the printer.

Preparing the paper:

⇒ Fold over one end of the paper before

inserting it into the printer

Inserting the paper

⇒ Insert the folded-over end of the paper into

the mechanism

⇒ Turning on the printer supply ⇒ Press and hold the FEED key until the

paper emerges from the outlet slot of the mechanism

Tearing off paper

⇒ Pull the printout across the direction of

printout that it rests on the cutter bar of the printer housing

Do not pull printout upwards.

6 Operating elements

After the power supply unit has been connected to the printer and the mains, and after the ON/OFF switch of the printer has been switched to “ON” position, the red indicator for the power supply will light up. This indicator also signals that the printer is ready for operation.

7 Start-up

⇒ On start-up press the FEED key; printer carries out self-test

and parameters will be printed. Red LED is lit up, printer is ready for operation.

⇒ Press “FEED” key: Switch numerator on or off, when statistics function is „ON“ ⇒ Press and hold “FEED” button: Paper transport. ⇒ Press “FEED” button: Switch date and time on or off, when statistics function is

„ON“

10 Storage conditions and use of thermal paper

Long-term usability of thermal paper is achieved by correct storage.

Storage:

- Dark storage location (no direct sunlight)

- Maximum relative air humidity 65%

- Maximum temperature 25°C

Always store printed paper under the following conditions:

- Do not expose to direct sunlight or intensive room lights

- Avoid contact with alcohol, solvents or similar substances (e. g. adhesives),

- Do not store inside PVC pockets

- Storage temperature < 25ºC.
