Page 58: Aligning The Gx Camera
A software program called PlotWorks is also needed and this is available on the Gx Service CD or the support website: www.colortracsupport.co.uk username: colortrac password: service. The CCD mounted on the camera board reflects off 2 mirrors and up through the gap in the extrusion. - Page 59 SmartLF Gx Service Manual Notes: Turning the 2 screws mounted under the camera housing will move the ends of the board allowing the CCD to be aligned to the target. It is far easier to run the PlotWorks program on a laptop, so the screen can be easily see without obstructions during adjustment.
- Page 60 SmartLF Gx Service Manual Notes: Make sure the dotted line of the target is central and straight along the scan line under the glass. Make sure the whole target is central to the scan glass width, so the ends of the lines are the same distance from the paper hold down bearing at either end.
- Page 61 Gx Service CD or the support site. This installation does NOT put an icon on the desk top, so it needs to be located to run. The location for the installed PlotWorks program is: C:\Program Files\Colortrac\SmartLF Plotworks\PlotWorks.exe Page 61 of 107...

- Page 63 SmartLF Gx Service Manual Notes: The above image shows an aligned camera. The bottom line must be all the way down and level when the camera is aligned. If either end goes up at all, then the camera is not aligned. Scan Line Pictorial view of camera showing the position of the dotted line on the target compared to the blue channel of the CCD on the camera board of an aligned camera board.
- Page 64 SmartLF Gx Service Manual Notes: Scan Line A completely un-aligned camera. The CCD is nowhere near the dotted line of the target, so is not looking central to the scan line. Scan Line Scan Line Almost aligned. The camera is seeing the dotted line, but is looking diagonally across it.
- Page 65 SmartLF Gx Service Manual Notes: To align the camera, the 4 x pan head locking screws that hold the camera to the mount have to be loose. But not too loose so that the camera can move away from the mount, a quarter of a turn should be enough to allow the camera to move up and down.
- Page 66 SmartLF Gx Service Manual Notes: 10. Using the alignment screws, situated under the camera mount, move the camera up or down to locate the dotted line on the target. Camera Board Alignment Slot Locking Screw The easiest way to find the line is to move the board all the way up to the top (turn the screws anti-clockwise) on both alignment screws so the locking screws are at the bottom of the alignment slots.
- Page 67 SmartLF Gx Service Manual Manipulate the screws to position the camera board so that the Notes: image on the PC is correct. This means the screws can be turned in either direction to get it correct. There is no specific rule to this, it is down to moving the camera until the image appears as shown with the lines fully down, and may be a time consuming process.

- Page 83 SmartLF Gx Service Manual Notes: Feed the old belt around the lower mounting bracket to remove it. Fit the new belt around the lower mounting bracket, making sure the teeth are on the inside of the belt. Page 83 of 107...
- Page 84 SmartLF Gx Service Manual Notes: Rotate the mechanism back down, making sure the belt is fitted correctly with the belt coming from the top of the horizontal pulley going behind the pulley on the lifting bar. NOTE: If the belt is put on incorrectly, then the mechanism will work in the operate direction to the other end of the paper guide assembly and damage the scanner, so it is very important to fit the belt correctly.
- Page 85 SmartLF Gx Service Manual Notes: 10. Re-fit the locating pin back in to the hole in through the lifting bar and paper guide assembly, it may be necessary to move the paper guide assembly slightly to line the holes up. Tighten the pin back up.
