This error is displayed when a timeout occurs while the device is receiving the print data over the network.
There is a menu called [Timeout Injob] on the device.
This menu sets the waiting time (sec) of the device, from when the received data process is stopped until the page is output.
The default setting is 40 seconds and can be set in the range from 5 seconds to 300 seconds, or can be disabled.
For example, if a computer takes time to create a print data in a state where the print data is intermittently sent to the device little by little, a timeout will occur when the time set in [Timeout Injob] has passed.
The error is less likely to occur by setting a larger value in [Timeout Injob].
[Timeout Injob] can be changed on the device's touch panel. On the touch panel, press
[Device Settings] > [Admin Setup(*)] > [Print Setup] > [Print Menu] > [Print Adjust] > [Timeout Injob]
and change the value.
* Administrator login is required. The default admin name is "admin" and the default admin password is "aaaaaa".
