SERVICE CALL 0002000B (MAIL BOX MEMORY ERROR)

Problem
Data (also can be command code) reception error caused by outside
factors such as power-drain during PC-side data transmission or
printer reception. Also could be due to interference in interface cable
or a warn cable, and so on.
Solution

If you cannot regenerate the error, have a nice day.
Make sure no machines that share the same power supply (with the
PC or printer) are turned on while the print job is being sent.
Make sure the interface cable is within specifications for this printer.
Replace the interface cable; it may be worn out.
To make sure an errant command code is not the cause try sending a
different print job, or send the print job from another application or
another PC.

confirm whether the error recurs. If the same error recurs, replace the
