Solution

Overview

The 956 Processor Failure error normally requires a service call. However, it may be only a temporary issue and easily resolved without service. On occasion, a power fluctuation or a stray static discharge in the vicinity of the printer can cause a false error message to appear.

Resolution

  1. Power off the printer, wait ten seconds, and then power the printer back on.
  2. If the error remains, try connecting the printer's power cord directly into a grounded wall outlet, if possible. In rare instances, a surge protector or uninterruptible power supply (UPS) can generate false error messages.
  3. If the message persists, please continue to 'Contacting Lexmark'.
