Occasionally the cookie does not print centered. Inconsistent print start positions. (Eddie).

1. Feed/Reverse Speed.  If the cookie moves during the scanning process before each print, it may not print centered.  You can slow down feed and reverse speed.  This will slow down the scanning process making it less likely for the cookie to move. To adjust these values, open PrintHub - choose the Printer Settings Tab - Advanced Settings.  Try setting the speeds to "10".

2. Template Size/Page Size.  Measure your cookie.  Make sure the template size and page sizes is the same or slightly larger than the cookie. (Page Size and Template Size in BarTender should always be the same) 

For example, if the template/page size in BarTender is smaller (3.0") and the cookie is 3.5", Eddie will find the size of the cookie using the cookie size sensor and start printing at the front edge of the cookie, but it will never reach the back of the cookie because the size you are sending the printer is 3.0".  The image will appear off-center in this case because the template size is 1/2 inch short. 

If you make the template size larger than the cookie, it will over print/overbleed slightly but you will ensure complete cookie coverage.

Example: 3.0" template on 3.5" cookie

You can use the same process to print to any shape such as a square template over a heart-shaped cookie.  The image/design shape does not need to match the cookie shape. It is OK to print onto the cookie platform or off the edge of the cookie.  The printer filters will take care of any extra ink overspray.  This works best for printing patterns where precise alignment is not critical.  For images with a white background this method does not work. 
Example: Square pattern template printed to heart shaped cookie

3. Ensure that bright light is not shining into the printer.  This can disrupt the cookie sensor's ability to detect the cookie size for centering purposes.  Close the tinted front lid or move the printer away from the light source.

4. Install the tinted cover.  Make sure you install the tinted cover.  It helps block any excess light from affecting the cookie sensor.
5. Perform a tray calibration.  If the tray is out of calibration, it can affect the placement of the cookie on the platform/tongue.  Press and hold Load/Unload + Pause for 3 seconds to start the calibration. 

6. Disable the centering scan. (optional - advanced)  Open Print Hub on PC only.  Go to printer settings - choose Advanced - uncheck "Cookie Centering Scan".  The printer will no longer perform the scan.  Instead, it will start in a fixed position. 
  1. To adjust centering, you will need to manually adjust the Horizontal Offset and Top of Cookie Offset. (See screen capture below)
  2. When you turn off the centering scan, you must place the cooking in the exact same place on the tongue/platform every time.  This is hard to do by just eyeballing the position on the tongue.  When the cookie is not placed in the same place (either left to right or front to back) every time, it will look like the image is not centered and jumping around inconsistently. 
  3. The Milton tray or a DTM tray will help you place the cookie in the same spot every time.  Search the Facebook group for the Milton Tray links.
  4. The cookies have to be a consistent size for this option to work. 
  5. If you do not have a tray, you can attach a piece of thick (.08" or thicker) cardboard to the platform/tongue that is larger than your cookie size.  Make sure it is attached firmly, so it will not move around.  Print your design with no cookie in place.  Note the location of the print on the piece of cardboard.  Now place your cookie centered on the print location.  Print again. 

7. Ink overspray mist may be interfering with the cookie size sensor.  Clean the cookie sensor with a damp cloth. It may also be beneficial to clean the filters, as shown in Section 6C of the manual.  A clogged filter can cause ink overspray mist to build up more quickly.
