Hi MiroSorry I thought I had sent a response to this already. Printer is connected wireless connection. I have sorted out the scanner problem by ticking the box in the set up. However, I have to switch the printer off and then back on to wake it up and then I can print/scan without problem. Once I stop for a time (say around 10 minutes) - printer goes back to sleep and I then have to switch it off/on again to do some more printing

Hi again!

Sorry for not responding earlier - I was away from the computer for a few days.

I see the scanner problem has been solved. Regarding the sleep problem: please tell me when it first occurred? Also, does the printer go to sleep when you use it without a computer, for example when you want to copy a A4 document (paper)?

Thanks,

IT Miro

Hi MiroStarted a couple of months ago.Yes it does. Cannot copy scan or print without switching on and off. Stays awake whilst I am using continuously, eg scanning a range of different documents. Then, When I haven't used for 10 minutes or so it goes to sleep.Previously I used to press a button on the top right hand side if the printer and this would wake the machine up but it doesn't work now

Thanks for the additional information!

I checked about this sleep mode problem and noticed that many people seem to be experiencing it with other Canon multi-functional printers as well. A solution to the problem quite surprised me - you need to change the wireless modem settings to work only on 20 MHz channel, rather than 40 MHz channel or Auto.

Check the discussion between several Canon users here:

http://tinyurl.com/zb6t56g

It is for model MF8380CDW, but it should work for your model as well.

This sleep problem must have started to occur for you when changing the wireless router, or when you switched from wired to wireless connection. The printer uses different energy saving mode depending on how it is connected to the network.

Based on the printer specifications available on this link:

http://tinyurl.com/hhffb88

the printer consumes 23 Watts in standby mode, 1.4 Watts when in energy saving mode connected using wired connection and 2.2 Watts when in energy saving mode connected using wireless connection.

So, if you disconnected the printer from the wireless connection and switch it back to the wired connection, the sleep mode problem should be solved automatically. In order to continue using the printer on wireless connection, you will need to access your wireless modem settings and change the wireless network settings to work only on 20 MHz channel. In case you don't know how to do that, please type your wireless modem make and model and I will provide the instructions for you.

Best regards,

IT Miro
