Although the printer requiresvery little maintenance, with normal daily use you will need to perform some routine maintenanceprocedures, including replacing consumable items and cleaning the printer. This chapter also con-tains information about moving and storing the printer.Upgrading Printer FirmwareThe executable firmware for the printer controller is stored in FLASH memory. You can easilyupgrade this firmware on site when a new version of code is available. The upgrade process involvessending the new code, which is usually named with a .LOD extension, to the printer using eitherthe parallel or network interface. When the printer receives the file, it will automatically recognize itas a firmware upgrade file and will program it into the FLASH memory. During this process theprinter will display information about each sub-file that it is receiving or programming. When fin-ished, the printer displays the text “Upgrade Completed” and reboots, executing the new firmware.Contact your dealer or service provider for more information about firmware upgrades.Upgrading Firmware Using the Parallel InterfaceTo upgrade the printer using the parallel interface, go to the DOS prompt and use the copy com-mand to copy the new file to the printer. For example, type “copy newversion.lod/b lpt1” at theDOS prompt, where “newversion” is the name of the firmware upgrade file and “lpt1” is the printeryou would like to upgrade. Be sure to use the “/b” switch on the copy command line to ensure thatthe data is sent in binary mode.NOTE: If you are using a PC that is not running Windows or if you do not have any printer driversinstalled and configured to use the parallel interface, you will need to configure the parallel portfor permanent retry by entering the following command PRIOR to entering the copy commanddiscussed above: mode lpt1:,,pIf you are running Windows, you may get an error message during the upgrade process thatindicates that the printer is busy or that there is a printer error. This message box will containcheck-boxes for “Retry” or “Cancel”. DO NOT SELECT CANCEL. This error message is only aresult of the printer programming a large file into FLASH memory and will disappear once theprogramming is completed.Upgrading Firmware Using the Network InterfaceTo upgrade printer firmware using the network interface, simply send the new file to the printerusing whatever procedure you normally use to send a print file. This procedure varies depending onthe network environment.
