HECK RE THE PRINTER AND COMPUTER SECURELY CONNECTED
Check the printer cable connections at the printer and computer. A faulty
or loose connection can generate meaningless characters and symbols to
print.
C 4 I
HECK S THE PRINTER PORT SET TO
When the printer port of the computer is set to the ECP mode, the printer
may not perform a print job properly. Cancel the ECP mode, and print
again.
If the problem is not solved, contact your computer manufacturer.
C 5 I
HECK S THE PROBLEM IN THE ORIGINAL FILE
If meaningless characters or symbols are printed only when you print a
certain file, the cause of the problem may be in the file or the application
program you are using. Rebuild the file and print it again.
If the rebuilt file prints correctly, the original file was probably faulty.
If the rebuilt file does not print correctly, contact the applications company.
