Cross - Platform Arcus

Will my scanner work on both Mac and PC platforms?

Yes. The scanners are exactly the same for both types of computers. However, if you are going from a Mac platform to a PC-based computer, you will need to purchase a SCSI controller for your PC.

Arcus Calibration Errors

Why do I get calibration errors when scanning transparencies and negatives?

The scanner was shipped with a transparency template. To avoid errors, be sure this template is being used and is installed correctly. It should be placed flat on the glass with the word AGFA toward the back of the scanner.

There are two open areas in the template. One is a large 8" x 10" hole, and the other is a small 1/2" strip cut-out. The large opening is the scanning area and the other is the calibration hole. Never put anything in the calibration hole, as doing so can also cause calibration errors.

Correcting Mechanical Interference

Arcus Scanners can emit a loud chattering sound at the end of the forward scan due to mechanical interference between the CCD PCBA cover mounted to the mirror/lamp chassis and the underside of the top cover support frame.

To correct the mechanical interference:

  • Turn off and unplug the scanner.
  • Remove the 2 long screws at the rear (screws holding the original cover or the Transparency Option).
  • If there is only an original cover, simply lift to remove it.
  • If there is a Transparency option, unplug the Power Supply and communication cables, then remove it.
  • Remove the 2 short screws at the front and remove the top cover.
  • Locate the proper cover per the illustration, and remove it.
  • Reform this cover as follows:
    • Place the CCD PCBA cover on a solid surface.
    • Hold it firmly and form the end down slightly in the direction indicated by the arrow.
    • Reinstall it and ensure the cover clearance by running several scans.

Cleaning the Arcus Scanner

Materials needed :

  • Lint-free cloth.
  • Industrial non-streak glass cleaner.
  • camel hair brush.
  • A can of compressed air.

Cleaning scanner bed and transparency glass

Important: Never spray cleaner on, or in, the scanner.

To clean the bed or transparency glass, apply glass cleaner to a lint-free cloth and apply the cloth to the glass until all lint and dust have been removed.

Cleaning glass and calibration strip

To clean the underside of the scanner bed glass and the calibration strip:

  • Turn off the scanner and remove all cables.
  • Remove the two Phillips screws that hold the transparency unit or scanner cover in place.
  • Remove the scanner cover.
  • Remove the two Phillips screws in the top front of the scanner.
  • Lift the scanner's top cover upward until it has been removed.
  • Turn the cover over and place it on a soft surface that will not scratch the glass.
  • Apply glass cleaner to a lint free cloth and apply the cloth to the glass until all lint and dust have been removed.
  • Use compressed air to blow away any lint or dust that remains on glass.
  • Clean the white calibration strip. The Arcus uses this area to calibrate the light source. It must be free of lint and dust.

Cleaning the optics mirror

While you have the scanner open, check the mirror located under the scanner lamp for dust and lint. Use a camel hair brush or compressed air and extreme care when cleaning the mirror since it is front silvered and easily scratched. When using compressed air, use short bursts along the length of the mirror. By applying air close to parallel, the dust and lint will go to the outer edges of the scanner. Do not apply air straight down on the mirror as this will lodge lint and dust further into the optics of the scanner.

Reassembling the scanner

  • Place the Arcus top cover back on the scanner.
  • Replace the two Phillips screws in front of the scanner.
  • Place the transparency unit or original cover on the scanner bed.
  • Replace the two Phillips screws that hold the transparency unit or original cover in place.
  • Reattach all cables.

Cleaning the Arcus II Scanner

Required materials :

  • Lint-free cloth.
  • Industrial non-streak glass cleaner.
  • Camel hair brush.
  • Can of compressed air.

To clean the Arcus II scanner, follow the steps below.

  • Turn off the scanner power switch and disconnect the power plug. Wait at least 15 minutes to allow the unit to cool down.
  • Unscrew the two screws at the back of the base.
  • Pull the SCSI board out enough to disconnect the ribbon cable that threads through the opening in the base (on the right)
  • Remove the two screws from the upper portion of the back of the base.
  • Remove the Transparency Option (TPO) from the base.
  • Remove the two screws from the top back of the base. These screws will be visible when the Transparency Option is removed.
  • Remove the two screws from the top front of the base and lift the plastic housing off the scanner.
  • Move the carriage to the center of the glass for easier access to the mirror and calibration strip.
  • Turn the cover over and remove the 11 screws on the bottom of the TPO.
  • Turn the TPO over again and separate the plastic housing from the TPO.
  • Apply glass cleaner to a lint-free cloth and apply the cloth to the glass until all lint and dust have been removed. Never spray cleaner directly on or in the scanner as it may penetrate the seams around the glass.
  • Spray compressed air outward to eliminate any dust collected inside or on the Calibration Strips.
  • To reassemble the scanner, reverse the order of the above steps.

Note: Slide the SCSI board, which the cable from the Transparency Option plugs into, to its original position before securing screws for the transparency cover. This will prevent any tension that could cause the ribbon cable to be punctured by the screws being secured.
