IBM CF Series manual Task - Filter Cleaning and Replacement

6.9 TASK - - FILTER CLEANING AND REPLACEMENT

The scanner has one reusable metal mesh air filter located on the left side of the scanner frame, near the slotted air-intake vents on the back of the left panel. This filter must be cleaned periodically to insure adequate air flow to the scanner (air cooled) ventilation system. If damaged sufficiently to allow debris to enter the scanner, it should be replaced. In either case, the filter is removed using the following procedure.

1.Remove the front panel from the scanner (refer to section 6.1 for detailed instructions on how to do this. Be sure to disconnect the earth-ground wire connecting the front cover to the scanner frame.

2.Remove the air filter for cleaning or replacement by loosing and removing one or both of the holders securing the filter to the frame. The holders are located inside the scanner’s left panel at the top and bottom of the filter. Each bracket is secured by two pan head screws to tapped holes in the frame.

3.To clean the filter, wash it in warm water, let it air dry, and spray it lightly all over with filter spray (Scangraphics Part # A64168) before you re-install it. If replacing the filter, you should still spray the new filter with the filter spray before installation.

4.Secure the new or clean filter back into its proper position. Tighten the screws so that the filter holders hold the filter flush to the panel, without any play that could cause vibration noise when the scanner is running.
