Removing the paper insertion guide • Remove the jammed paper, drawing it out carefully from the rear, with taking care not to damage the feed mechanism.

  • Page 107: Printing Problems

    Troubleshooting CAUTION: The most common cause of paper jamming inside the paper tray is the addition of paper to the tray when it is not empty and / or the incorrect loading of paper. When adding paper to the paper tray or after removing jammed paper, ALWAYS remove any paper already in the tray, fan it, and reload it all as a single pack.

The first time you call it, it will ask you to confirm or change the output port. For details about file spooling etc., see in your DOS Manual.

  • Page 124: Software Applications

    Printer Controlling Software Applications The printer performance can be controlled using software programs developed for a wide variety of applications, such as word processor, spread sheet, data base, graphics, etc. The software transmits the operating information to the printer in two different ways, with: - The Printer Driver: the part of the program which controls the selected printer - Incorporated commands: inserted directly in the text to be printed.
  • Page 125 Printer Controlling Due to the application software A driver can handle only the information transmitted to it by the application program. If, for example, the application does not handle bold-face, your printer will never print in boldface, even though it is capable of doing so. Inherent to the driver Only the information contained in the driver program can be acted upon.

  • Page 128: Sending Files To The Printer

    Printer Controlling Sending Files to the Printer When you want to print from a word processor, spread sheet, database, graphic package or other application, always use the built-in print function they offer. Do not attempt to send one of the package's work files directly to the printer, as they rarely have a format which can be executed directly by the printer.

    Command Codes There is also a special command ESCAPE (decimal code 27, named ESC) which is used by most printer emulations to open a command sequence. It is followed by one or more additional characters, which are identifiers and parameters, belonging to the printable characters or to those from the range of control codes.

    Technical Characteristics Slow Down Mode To avoid "time-out" problems with MS-DOS operating systems, the printer automatically reduces the reception speed when the line buffer is 60 characters from capacity. In this situation, the printer accepts only one character every five seconds from the line, thus guaranteeing that there will be no reception interruption for time-out for at least 300 seconds.
