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.

6 YKS-01-BA-e-1010
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“

8 Statistics function
To create statistics, the numerator must be switched on.
After having processed several weighings, statistics will be printed by pressing the
functional button:
Example Numerator 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.

Symptom Remedy
The supply indicator is not
lit up.
Check whether the power supply unit is connected to the printer and to
the mains.
Paper does not emerge. Check whether the paper has been inserted correctly,
whether the input slot of the mechanism is free of obstructions
Paper leaves printer
without print:
Check whether the paper has been inserted with its thermo-sensitive
side facing the printer head, whether the SW switches are set correctly.
No printing is taking place
and paper does not
emerge.
Check whether the connecting cable is connected at both ends,
whether the printer prints during the self-test, whether the SW switches
are set correctly.
Wrong characters are
printed
Check whether SW switches are set correctly.
Printout is blurred Check whether operating temperature exceeds allowed value, whether
the paper used is recommended by the manufacturer.
If you are unable to remedy the error, please contact your supplier.
