Logs

Several lines in the report are logs rather than counters, for example, the PostScript Error Log.  Each time a PostScript error occurs (and the user has enabled the Error Handler), the PostScript error is recorded as a numerical code along with the page number on which the error occurred. 
 
On each successive error, the log is shifted to the left, with the oldest one being removed from the left end, and the new one being added to the right end. Note that a value of 0 (zero) in the log indicates no error. There are actually two lines for each log, one for the code and one for the page number. (In the case of last jam, there are three lines--paper code, location code, and page number.) 
   NOTE
 
 
For information on solutions to engine errors, see the 
Advanced Features and Troubleshooting Manual
 on the web or on your printer's CD-ROM.
