Problem with printing on the Xerox 3335 MFP?

Question

Seal

We have 10 pcs. MFP data (Xerox WorkCentre 3335) and all have the problem described below.
Connected via network (RAW), gigabit network, drivers installed correctly.
The problem is that after a long downtime of the MFP (after a night) from the moment the print job is sent to the first sheet, it takes 10-15 minutes (the MFP does not turn off at night). And then the problem does not recur during the day. Sometimes it helps to go to the WEB interface and click "Update the status of the local user interface", after which printing starts after 1 minute.
Firmware: v60.006.06.000.
The following was also noticed: if you go to the WEB interface before sending, then all tabs open quickly. After sending a print job - the "Jobs" tab does not open, does not respond.
Please tell me any additional ready to provide information.
Thanks in advance!
