Lexmark Optra K 1220 Installation And User Manual page 93

If the End-of-Job Timeout is greater than the DISCINTV value, errors are very likely
to occur if the printer requires user intervention. If, on the other hand, the End-of-Job
Timeout is smaller than the DISCINTV value, an error is certain to occur the first time
the MarkNet card times out after a completed print job. Therefore, the End-of-Job
Timeout should be set to 0 (disabled).
The End-of-Job Timeout can be set with the MarkNet configuration procedure. Please
refer to the Lexmark Network Adapter User's Guide.
For activation timeout errors, set the connect timer or activation timer in the PSF
settings to 30 second or greater.
