thx! that was it!
By default, the printer tried to print a page (or maybe i tried a test one, don't remember), but didn't put any paper yet in the tray... once I cancelled everything in the job list, it worked.
Check yto see if there is no job in progress.
more info, trying to do a factory reset as explained here:
ie, hold on Home button for 10ish seconds, and then do "Service" login with default password "6789". but then, guess what? whatever I try to access there (eg Devices->Resets or Devices->General) I get the "Unabe to contiune. Try again later"
I am having exactly the same problem. My new 6515 printer is completely unusable now.
What is the source of the issue: "Unable to continue. Try again later" ?
I tried everything, even trying to set the same password as the one for my account for this forum (at least 8 letters, some upper cases, digit and special symbols)... but still getting the same uninformative error.
The link provided by Rebecca924 does not say anything about this error.
So what should I do?
Change the system administrator password at the control panel:
If you want detailed information, then please visit the available link below.
I logged in to the admin account with the serial number as the password.
And then, I tried to change the password.
But!!!!! It does not work.
The printer shows the following message, "Unable to continue. Try again later.".
How should I do?
