System Operation 3-11
There are two ways that a downloaded file will have a missing EOF. The first is if printing through the printer driver and printing is canceled, interrupted, or file size exceeds the remaining free memory space. If this occurs, chances are that the EOF never made it to the memory buffer and the memory buffer will show that it is empty or that the file does not exist. Part of the file might still remain in memory and might become mixed up with other files. This is why having the ability to insert an EOF marker from the control panel of the laser system is very important. In order to delete that partial file, the memory buffer must either be cleared entirely or an EOF must be manually inserted into the memory buffer. Inserting an EOF is the better choice here because the partial file can be deleted without disturbing the other files in memory. Secondly, when using DOS based programs, a printer driver other than the Windows printer driver must be used. DOS printer drivers do not know to send the required EOF to the laser system after file downloading. Again, the memory buffer will not recognize any file that exists if it does not have an EOF. In this case, an EOF must be manually entered into the memory buffer after each and every file download from a DOS based program. Since DOS printer drivers also do not send the name of the file within the file data, every file will be called “NONAME” once an EOF marker has been inserted. To distinguish one “NONAME” file from the next, the display will number the files in the order from which they were downloaded.
To insert an EOF marker in either case, position the cursor on the first line of the display where the filename is. Press and hold down the “NEXT FILE” button and then press the “SELECT” button at the same time. The word “NONAME” will appear if there is a partial file in memory or any DOS based file that does not have an EOF marker. What has happened is that the laser system searched for any file information that had entered into the memory buffer since the last completed file was downloaded. If it finds information, it scans to the end of the last bit of that information and inserts an EOF. The file then shows up on the display as “NONAME” and will allow either its solitary deletion without having to delete the other files in memory or it will allow the file to be run just as if it was downloaded from the Windows printer driver.
