There is an update for your printer. This is a firmware update. A firmware update, rewrites code located on the printer's main system board. The latest update is dated 10/17/08.
Flashing firmware does not have a go back element or undo, so it is really important that we verify your model and what seiries of printer you have. I suspect you have a CLP-300 Series printer and that the 310 of the 300 just describes some features added or left off and even who you purchased it from, in many cases.
Please look at these two photos and then post the data off the name plate for your model number in particular.
You will notice there are two lines to include in your reply.
1.) The Model: (first line)
2.) M/C entry (second to last entry in this photo of the label.
Once you verify this and I post the firmware update link for you, you will need to follow the instructions I include below.
