Solved. Same symptoms: can charger, blink blue in millisecond with power button.

Open the left cap, apply pressure on flex cable, then power button works normal.

My solution is to use Mounting Tape (which comes with certain thickness) in order to apply pressure on the same spot.

johnny4705, try this first, and reset the purge counter. These steps worked in MFC620CN/420CN/410CN/210C/240C and FAX2440C model.

To reset purge counter

1) Enter machine maintenance mode (on MFC240C all four photo/copy/fax/scan lights flash in maintenance mode). Care is needed in maintenance mode, otherwise critical settings may be inadvertently corrupted.

FAX models with numerical keypads: Press the Menu/Set, *, 2, 8, 6 and 4 keys within two seconds. (if you fail to complete the correct key sequence within two seconds, press the Stop key to try again).

Other (non-FAX) models: Press the Menu/Set and Black Start keys. Next press the “up arrow” key four times to enter the maintenance mode).

2) Press the 8 then 0 keys in the initial stage of the maintenance mode to call up the machine’s log information list (function code 80).

3) Press the Black Start key several times to scroll through the log information list to reach the purge counter. The purge counter is the 25th item in the list.

4) Press the 2, 7, 8, and 3 keys in this order to reset the purge count to zero.

5) Press the Stop/Exit key to return to the initial stage of the maintenance mode.

6) Press the 9 key twice to return to the standby state. from here. Hope this helps, good luck.

No jayeff that is not what they meant at all. Come on you must of understood what they actually meant. I will tell you anyways. What they meant is when going to accounts In the main settings of the phone, it does not have samsung in the list of accounts to add. carladay actually made that very clear. Yet you responded assuming something completely different. Not helpful, just saying.
