Protocol for using the JEOL Digital Scan Generator
To open a new session and capture images:
1. ) Turn on the computer next to the SEM console. There are separate buttons for the monitor and the computer itself. The computer will run through its boot files and then ask you what number to choose. Please choose "1" (for the DSG1 program) and then press enter.
2.) Several things will flash by on the computer, and then it will ask you for a username to login to the NetWare servers. You have 2 choices. You can enter semuser which will cause all files saved to the network to end up in the public 1-day swapfolder (on Fabio) in a folder called images. You'll want to move them from this location to a more permanent place after your session with the SEM. (You'll need to use a computer somewhere else to do this). The other option is to login with your own NetWare account (the one that gives you access to your personal folder on Fabio or Celeste). Students without NetWare accounts can sign up for them at the SCIC desk in the CMC. The login procedure for students is the usual one: put in something like "smithj.s" for the username, and your normal NetWare password. Once DSG1 starts you'll be able to save files to the network and they will end up in your personal folder on Fabio in a sub-folder called IMAGES. Make sure there ís enough room in your space on Fabio for all the images you plan to save. If you're a faculty member you'll need to type a username of the form "ssinger.biology.fac.." (with two periods on the end) and provide your usual NetWare password. Files saved to the network will end up in your personal folder on Celeste in a folder called IMAGES. In all cases the IMAGES folder will be automatically created if it doesn't already exist.
3. ) Now you should press the system enabler button which is located on the box on top of the SEM console. You may now place your sample inside the SEM, making sure to follow the directions pertaining to normal SEM procedures. Please follow these procedures until you are ready to record an image.
4. ) You must be in "Pic1" mode when you are ready to take a scan. When you are ready to record a scan simply click on the "RECEIVE" button located on the left side of the JEOL program display. The computer will now ask you for image preferences. Please stick to the default selections, as they work best. After taking the pertinent information, the computer will scan the image and then ask you for image information. It is pretty self-explanatory. You can now adjust the contrast, filtration, etc. by clicking under the "OPTIONS" heading .
5. ) To save your new image, click on the "OPTICAL" icon on the left hand of the JEOL program display. The program will now ask for some more information, including a title for what is known as a "thumbnail" image. This is just a small picture of the entire scan that can be used when looking at the entire sessionís images. When all the information is in, the computer will save the image to a NetWare server. The exact location is explained in step 2.
6. ) To end the session (which you should always do), go under "SESSION MANAGER" and pick "CLOSE SESSION". When this is done, you may then "EXIT TO DOS", which is located under the 'EXIT" heading on the far right-hand side of the screen.
To take a look at an old session:
1. ) Open the JEOL program using the instructions above.
2. ) Under "SESSION MANAGER" choose the "EDIT SESSION" option. You will then have the choice of looking at any old session that is saved to disk. To look at an old session's pictures, highlight the session title and click on "IMAGES". You can then select a particular image from the old session by highlighting it and clicking on "LOAD".
3.) If you forgot the number of the image you were looking for, or are just: curious as to what images are on a particular session, you can click on the "TNAIL" (thumbnail) button after hitting ''IMAGES" from the step above. This will show you small images (thumbnails) of the images that were saved for a particular session. To access a particular image associated by thumbnail, you need to remember the image title and close the screen with the thumbnails. This will bring you back to the "IMAGES" screen, where you may choose and "LOAD" the full-size image.
To add, delete, or manipulate old images:
1. ) Open the JEOL program using the instructions above.
2. ) Under "SESSION MANAGER" choose the "EDIT SESSION" option.
3. ) Click on the session desired and then click on the "RE-OPEN" button. You may now add, delete, or change images as you wish.
If you get a message saying the device is out of space when you try to save to the optical drive, it may mean you arenít connected to the network. To fix this you can restart the computer and follow the steps above. It may also be that the network space (which depends on which of the options you choose in step two) youíre trying to save to is actually full.
Printing to the Alden Thermal Printer
You can print directly to the Alden Thermal Printer from within DSG1 by hitting the print button. You'll want to make sure the printer is turned on (there's a power switch on the side) and online (there's a button on the top). When you're done printing you'll want to release the tension on the paper by lifting the lever on the right that hides beneath the clear plastic guard on top of the printer. If you wish to print images not generated within DSG1 on the Alden Thermal Printer here are the additional steps.
1.) Make sure your file is in TIF format and is set to print at the correct size. There is no software to do this on the SEM computer so you'll need to work elsewhere using something like Photoshop. If you're using Photoshop you'll want to check the final print size as listed under the Image Size option in the Image menu. Be sure to save your file as a TIFF with PC byte ordering (this choice will appear when you Save the file as a TIFF) and choose a name that is less than eight characters long with a ".tif" extension - e.g. image1.tif
2.) Move the file to the space that is mapped as the "k:" drive when you login to the account you plan to use on the SEM computer. For faculty this will be your personal home directory on Celeste. For students this will be your personal home folder on Fabio. If you login with the SEMuser account you'll need to put the file in the Swap Folder on Fabio. Make sure the file is at the top level of the folder that is your k: drive.
3.) Login on the SEM computer as in steps 1 and 2 at the very top of this document but choose the option to go to DOS mode. If the prompt isn't already "k:" change it to that by typing "cd k:\"
4.) Print the TIFF file by using the command "tprnt -x1 image1.tif" substituting the actual name of your image file in place of "image1.tif". You'll need to hit return for the printing to start. The -x1 forces the printer to print the image at the size you specified when you created the image. If you omit this it will automatically scale the image to fit the paper size.
