Plustek original power supply unit - such a power supply unit is/was included in the scope of delivery of the following film scanners:
During the period of use more and more dust and dirt sets on the contact surface and the corners of a film holder. Consequently dust gets on the film material and into the scanner. Hence the film holder should be cleaned again and again. The easiest way is simply brushing the film holder with an anti static brush, which not only removes the dust but also removes electric charges. Discharging is important because electric charge adducts dust as is generally known. Kinetronics anti static brushes are available in different sizes.
When working with film strips it can often happen that you accidentally touch the emulsion side of the film. The damage often is irreparable. You can avoid damages to the film material and comfortably insert film strips into the scanner or film holder by wearing fine cotton gloves.
Anti-dust spray is used to clean film material - no matter if it's mounted slides or film strips - by removing dust and fluffs with a flimsy current of air without touching the film material at all. There is no better, more comfortable and more efficient way to clean your film material.
For working with single negatives or positives we highly recommend using tweezers, because otherwise you run the risk of touching and damaging the film.
