Canon MF8580Cdw User Manual page 518

Set the time period after which the machine deletes incomplete print data from memory. The machine deletes incomplete print data
because it may have some errors and prevent the machine from printing the next document.
5 to 15 to 300 (sec.)
NOTE
Provide the machine with enough time to receive all the print data from the computer, especially when printing large amounts
of data. If you specify a time period that is too short, the machine may not receive all the print data in time for printing.
