IMPORTANT:
Instruct the customer, not to fill the input tray with dropped films or films coming from
jam clearances:
•
These re-inserted films can be contaminated with dust and fingerprints which
can result in image artifacts or a defective thermal head.
•
If the film is inserted the wrong way, the thermal head gets heavily
contaminated, what makes a service intervention necessary.

Use a lint free cloth lightly moistened with isopropyl – alcohol or a
cleaning issue.
For the isopropyl – alcohol: Less water in the alcohol is better.
Water can damage the thermal head. We recommend using a 90%
isopropyl – alcohol.
Dismount the thermal head before dry cleaning.
Make a linear cleaning movement, parallel to the resistor line.
Refer to Figure 21.
