  • Page 169: Terminology

    Camera Design Overview Introduction HP Designjet scanners use three or four cameras. Each camera scans its own part of the image. The cameras are named A, B, C and (for the HD and T1200 HD MFP scanners) D, from right to left.

  • Page 170

    The CCD Element The central component of the Camera is the Sony CCD (Charge Coupled Device) element, which is responsible for capturing the colors reflected from the original image. The CCD is formed as a chip, and is inserted into a standard dual in-line socket just like a normal chip. The chip has 4 rows each containing 7500 pixels.

  • Page 171

    When the Scan-Width Screw is screwed in, as illustrated on the left side of the above picture, the camera has a greater possible scan-width. When it is screwed out (right side of picture), the camera has a smaller possible scan-width. The Scan-Width Screw is fixed on the camera assembly and not on the scanner chassis.

  • Page 172: Adjusting The Camera Manually

    ● CCD Centering: Moves the CCD Mounting Plate and the CBE Camera Board horizontally left and right and thereby making the field of vision move horizontally left and right. The camera itself can be tilted up and down which causes the field of vision to move up and down. The Vertical Positioning Hexagonal Nut is used for coarse adjustments and the Tilt Levers are used for finer adjustments.

  • Page 173

    A software oscilloscope is now activated and looks something like this: You see the uncorrected light profile, for Cameras A, B and C that the scanner receives from the reflection of the White Background on the back of the Guide Plate. Camera A is on the left, Camera B is in the middle and Camera C is on the right.

  • Page 174

    Wait approximately 90 seconds until SCANtest 6 is ready. Insert the Focus Pattern in the scanner. It’s best to insert the sheet from the back of the copier and use the Reverse Key to position the pattern correctly. This way the sheet won’t cover the cameras when you adjust them. It requires a little practice but makes the focus adjustment a lot easier.

  • Page 175

    Loosen the Focus Lock Screw and turn the Lens Adapter to adjust the focus. The Focus adjustment greatly influences the Scan-Width. Therefore, the Scan-Width must be checked and readjusted whenever the Focus adjustment has been changed. The Focus adjustment, however, is relatively tolerant to Scan-Width adjustments. After adjusting the Scan-Width, check the Focus adjustment again;...

  • Page 176

    Keep in mind that if you adjusted the Focus, the Scan-Width has changed and must be NOTE: adjusted. There is a mark on every lens, which indicates its “best position”. If you have completed the focus adjustments and this mark isn’t pointing upwards, mark the upward position on the Lens Adapter. Turn the Lens Adapter and loosen the Focus Lock Screw and the three Lens Fixing Screws (with a 1,5 mm Allen key).

  • Page 177

    Each of the black lines represents a scan-width unit (SWU) as does the white space in between the lines. This makes a total of seven SWU’s. The black lines and whites spaces work like a marker or indicator that tells you how wide the camera scan-width is.

  • Page 178

    This is what Camera A is going to see, when the scan-width adjustment is finished: Camera A scans from right to left, so the image above is a mirrored section of the total Scan-Width pattern as the copier actually sees it. The camera only sees a single line of pixels with the green CCD pixel line that we enabled under step 2.

  • Page 179

    The output we are aiming for can be seen below, therefore: ● The left output is too much to the left – if you have an output like this, you need to slide the CCD board to the right by turning the CCD Centering tab upwards. ●...

  • Page 180

    When you have six SWU’s in total, use the CCD-Centering lever to adjust the camera so that there is three SWU’s on each side of the camera as shown below: Check the focus again because large changes to the Scan-Width adjustment also affects the focus. If the focus needed adjusting, start over with the Scan-Width from step 4, because a slight change in the focus will affect the Scan-width considerably.

  • Page 181

    ● On the right image the vertical position is too high - if you have an output like this, you need to raise the left side of camera with the left Vertical Tilt lever, by turning it to the right. When you have adjusted the Vertical Tilt so that the output displays eight black lines (your output does not have to be identical to the above picture or the Reference Image, just close) on the left side of the camera, look at the right side of the camera.

  • Page 182: Adjusting The Camera Using The Camera Wizard

    When you have adjusted the Vertical Tilt so that the output displays eight black lines and four smaller lines (it doesn’t have to be precise, just close to the above picture) on the right side of the camera, look at the left side again to check that it’s still okay (it’s probably not). It very likely that you have to go back and forth between left and right a couple of times until both sides are adjusted the right way.

Select Next to continue. The next four screens contain information on how to perform the camera Adjustment correctly. Select Next after reading each screen.

  • Page 184

    In order to validate the current state of the cameras you will need to open the Guide Plate and place the Optical Adjustment Pattern on the Scanner. Align the pattern by pressing it to the right towards the Operator Panel and backwards towards the back of the scanner. Once the cameras have been validated, select Next to continue.

  • Page 185

    Once the Scanner detects that the Focus Adjustment Pattern is correctly positioned you will be able to select Next to continue. Select the camera that you need to adjust. Camera A is the one closer to the front panel. Remove the Focus Adjustment Pattern and place the Optical Adjustment Pattern on the Scanner. Align the pattern by pressing it to the right and backwards towards the back of the scanner.
