The special construction of the banknote checking device prevents soiling of the light barriers, but occasional cleaning may become necessary.

Do not use solvent-containing detergents such as alcohol, cleaning solvent, methylated spirits, turpentine, or circuit board cleaner for cleaning. Using these detergents can result in the destruction of the unit. Only use mild detergents.

It is possible to clean the banknote intake channel while it is assembled, but it is recommended to remove the acceptor head from the Merkur International Dispenser 100 PLUS.

Cleaning The Acceptor With The Cleaning Card

2. Insert the cleaning card like a banknote.
