Correct Fan Assignments and the 57.07 error in CLJ 4600 series

Error code 57.07 is not one that is found in the Color LaserJet 4610/4650 service manuals. We at LPT learned thru experimentation that this error is caused by the power supply fan. (The 4600 lacks this fan and does not get this code.)

As we verified the fan assignments for these printers, we noticed two things.

  1. Part numbers and reference designations in the 4600 and 4610/4650 service manuals were inconsistent, and
  2. There were subtle differences in the error codes which were not reflected in the manuals.

We compiled the correct information in the table to help you diagnose and repair fan errors in the 4600 series.
