Unlocking a Cisco 7940

Method 1:
1) Unplug the phone
2) Plug the phone back in while holding the # key
The phone will soon display “Reset key sequence detected”
3) After several lights flash press the following keys in order:
1 2 3 4 5 6 7 8 9 * 0 #
4) The phone will then ask you if you want to save the network configurations:
Save network cfg? 1=yes 2=no
5) The phone will soon display “Factory reset initiated” and will continue
through the boot up process.
If that process fails to work for some reason there
is a second method.

Method 2

Complete these steps:

1. Press Settings.
2. The Network Configuration lock symbol must be unlocked. If not, exit to the main window and press ** # again.
3. Press 3 on the keypad (or scroll down) for Network Configuration.
4. Press 33 on the keypad (or scroll down) to Erase Configuration.
5. Press the Yes softkey.
6. Press the Save softkey.

You can solve this by connecting your phone inline.
On the back of the phone where the phone handset plugs into, plug one end of the jabra headset wire & connect other end to the 2nd position (marked by phone & handset). Now plug the handset wire from Ip phone to the 1st position (marked by handset) in the jabra headset. Now you are good to go.

When the phone rings lift the phone handset and answer it with your jabra headset. You can't use jabra with 7941 without lifting the handset on phone.

Hi
IO have one of these printers as my daily workhorse. Thankfully I haven't had the problem you are having.
Did you remove the print-head from the printer and clean it with running warm water?
When I get a possible print-head problem I always do that, rinse it until the water runs clean. Then dry it on kitchen roll making sure that the contact on the back are completely dry before refitting it to the printer. Generally this has cleared any problems (I have several Canon printers - I'm not just referring to the 5200 now).
However If you still get the error it may be worth contacting your nearest Canon service centre. New print-heads are not exactly cheap but these printers are so good it's worth keeping it going. They will probably be able to diagnose the problem quickly and accurately and tell you if it is cost-effective to repair. I don't know what would be involved with the Eprom error. - probably a circuit board change inside the printer.
