Print error 016-799 - Fuji Film Xerox

016-799 Fuji Xerox or Fuji Film print error code. That shows a description error as “Print instruction Fail detected in decomposer.” The error code and error description are alien languages for users and even system administrators who are not familiar with Fuji Xerox error code. The error code is quite simple and easy to fix, if the job print goes to the printer but print out doesn’t come out. So, basically the print job was received by the printer, but the printer just doesn’t know what type of paper or what size to use or which tray to utilize for the print out. In some instances, this is just a paper mismatch but the error description; if using Windows 10 to print does not exactly points to what is the issue.

Delete Directories with Wildcards using rd or rmdir

  Deleting files in command prompt using wildcards is quite straight forward. Command below will delete all text (".txt") files on the specified path.      Del D:\txtlog\*.txt Command above will delete all files with ".txt" extension in d:\txtlog directory. Easy enough to delete all matching files. Using the same method with rmdir or rd command this will not work. For example, if we have a directory on d drive that is auto-generated by an application and the filename is consistent with a pattern plus incrementing number at the end to differentiate the folder from other folders.    D:\baklogs\log1\    D:\baklogs\log2\    D:\baklogs\log3\    Etc..    D:\baklogs\log100\ The folder name has a consistent pattern that is preceded by the word “log” plus incrementing number. If the command below is executed to remove the directories in one go, an error is shown which h...
