3.2.4  Details of Error Status and Remedy
OPTIONAL RAM ERROR (STATUS CODE: XXXX)
 Description
The optional RAM is faulty.
 Treatment method
Turn off the power and remove the optional RAM module, and then turn on the 
power.
CHECK DUPLEX P-SIZE (STATUS CODE: 4016)
 Description
Since the size of the paper fed in duplex printing is different from the paper size 
preset for printing, printing stops and a paper jam occurs.
 Treatment method
Insert paper of the appropriate size, open the covers on the paper feeding routes, 
remove the jammed paper, and then close the covers. The printer performs 
warming up and then resumes printing from the data at which the error occurred.
CHECK MEDIA TYPE (STATUS CODE: 4226)
 Description
Since paper other than transparencies was fed in transparency printing, or a 
transparency was fed in nontransparency printing, the printer canceled printing 
and ejected the sheet. In duplex printing, the sheet remains in the duplex printing 
unit that is causing a paper jam.
 Treatment method
1.  If transparency is specified, set transparency. If transparency is not specified, set 
plain paper. Pressing the Start/Stop button will let the printer recover from the 
error status, and the printer will start printing.
2.  If the printer does not resume printing, execute “Reset” or “Reset All” or press 
the “Job Cancel” button to delete the print job data or hold it down for more than 
two seconds to delete the data of all the print jobs.
