MF733Cdw will not sleep

I see a lot of people having problems with their printers not waking; however, I can’t get my MF733Cdw to completely sleep. “Auto Sleep Time” is set to the default of 5 minutes. I’ve double-checked all of the settings in both the control panel and the remote UI portal pages; however,

 

  1. Unit will not sleep if I press the ‘sleep’ button on the operation panel (per page 179 of the manual)
  2. After the (default) 5 minutes of idle time, the remote UI portal shows the scanner is in sleep mode; however, both the printer and fax are ‘ready for use’. While the ‘sleep indicator’ on the operations panel is illuminated (meaning the unit should be sleeping), the unit sounds like it is still in a ‘full ready’ status (fans/heaters on, etc). This is what makes me believe the unit is not completely sleeping.

Unit is networked via Ethernet, and fax receive mode is set to ‘manual’.

 

I suspect I’ve done something foolish which is preventing the unit from sleeping. Any thought/suggestions on what I’ve overlooked?

 

Thanks in advance for any assistance.

Re: MF733Cdw will not sleep

Hi Canononac,

 

When the machine enters sleep mode,  lights up yellow green. Situations in which the machine does not enter sleep mode

When the machine is in operation
When the Data indicator is lit up or blinking
When the machine is performing an operation such as adjustment or cleaning
When a paper jam occurs
When the receiver of the external telephone is off the hook
When the machine is set such that the fax incoming ring will not sound
When the menu screen is displayed
When a job is waiting to be scanned to a USB memory device or to a computer
When an error message is displayed on the screen (There are some exceptions. The machine sometimes enters sleep mode when an error message is displayed.)
When the machine is communicating with an LDAP server, etc.
When the SSID/network key screen for Direct Connection is displayed
When settings are being imported or exported

Re: MF733Cdw will not sleep

Hi -

 

Thanks; however, that is simply a cut-and-paste from the user manual, which is what I've been working from.  I was hoping for some guidance as to which specific settings and values can prevent the printer and fax from sleeping.  Again, I beleive I've followed the instructions in the user manual.

 

Thanks.

Highlighted
