I have a new install with two 4000DN’s with the sleep mode maxed out. They are printing very simple one page packing lists from Linux. After the printer has set for a few minutes, 3 or 4, the first page time out is 15 seconds, if they print to it again right away the first page out is 6 seconds. If they send additional print jobs to it they come out in 6 seconds or so, now if the printer sits idle for a little while, maybe a few minutes, the first print out will take 15 seconds again.

I don’t believe this is a driver or network issue. When they send the job the data light comes on immediately then the display reads processing. To be consistent I have tested it reprinting the same packing list. I installed the latest firmware as of yesterday, H8=25, S1=2. The spec sheet says first page out 9 seconds or less then in parentheses it says (ECOfuser off). I searched all the manuals, called tech support and nothing on ECOfuser.

Any ideas appreciated,

Interestingly enough the SALES brochure says 9 seconds, the TECHNICAL brochure says 24 seconds.

And people wonder about us techs.

If I read Tech Pub #1 correctly, 24 seconds from a cold start and 9 seconds or less from Ready?

Please look in the SERVICE MANUAL at the specs.

All I see in the service manual specs is a first out time for A4 of 24 seconds. The other specs are for warm up time with no reference to output speed. That is looking at rev.5 of the manual which is the latest I think.

My regional tech rep came through again.

Y2 needs to be set to a 1 (I think it said “On Demand Mode”).

I too have this exact problem. Can you advise me what Y2 means? and how too change it

Y2 says "On Demand Mode". It is my guess that by setting it to a 1 you are keeping the fuser at a ready temperature. Y2 is an FRPO setting. The easiest way to set it is through the command center with a web browser.
