Additional paper jam clear operations
If the LCD error message continues to appear and you repeatedly experience paper jams, do the following:
1. Unplug the machine from the electrical socket and open the manual feed slot cover.
2. Load one sheet of thick A4 or Letter sized paper, such as glossy paper, in the manual feed slot. Insert
the paper deep into the manual feed slot.
3. Re-connect the power cord.
The paper you placed in the manual feed slot will be fed through the machine and ejected. If the thick
paper is pushing any jammed paper out, remove the jammed paper.
