WF-C579, WF-C529 PF fatal error 3

Error name:

•  PF PID excess load error (error code: 000041)
•  PF PID reverse error (error code: 000043)
•  PF PID lock error (error code: 000044)
•  PF load position excess load error (error code: 000051)
•  PF load position reverse error (error code: 000053)

Cause:

•  State in which load of PF motor exceeds expected load
•  When rotated in the opposite direction to rotation direction
  (There was a sudden load error, and the motor rotated in the opposite direction in reaction to it)
•  State in which load of motor exceeds expected load, and motor does not rotate at all

Suspected cause:

•  Foreign object or jammed paper remaining
•  Paper path damaged and feed roller worn out
•  PF gear train part damaged
•  PF encoder failure
•  PF motor failure
•  Main Board Assy failure

Fix Epson WF-C579, WF-C529 error codes 000041, 000043, 000044, 000051, 000053?

– STEP 1: Check for paper jam paper remaining and foreign object

• Check that there is no paper jammed paper or foreign object remaining in the paper feed path.
  • Yes? – Go to step 2
  • No? – Remove the paper jam paper and foreign object.

– STEP 2: Check the timing of error occurrence

• At what timing does the error occur with the product?
  Does it occur when the power is turned on?
  • Yes? – Go to step 4
  • No? – Go to step 3

– STEP 3: Check the operation of the feed roller (Paper Guide Upper Assy)

• For feed roller, check the following items.
  • The feed roller is not damaged or worn out.
  • Does the roller rotate?
  Is the result OK?
  • Yes? – Go to step 4
  • No? – Replace the Paper Guide Upper Assy.

– STEP 4: Check for damaged or broken part in the paper feed path

• Check that there is no damaged or broken part in the paper feed path.
  (There is nothing hindering paper feeding.)
  Is the result OK?
  • Yes? – Go to step 5
  • No?
    –  When part can be replaced. Replace the damaged part.
    –  When part cannot be replaced Inquire at Epson Service Support department.

– STEP 5: Perform PF motor operation check 1

• Turn on the power and check the PF motor operation. Did the PF motor operate (rotate)?
  • Yes? – Go to step 6
  • No? – Go to step 7

– STEP 6: Perform PF motor operation check 2

• Is the PF motor operating normally? (The PF motor is not operating abnormally)
  • Yes? – Replace the Main Board Assy.
    (If the trouble is not resolved after replacing the Main Board Assy, inquire at Epson Service Support department.)
  • No? – Replace the PF encoder.

– STEP 7: Check the PF drive gears

• Check if a foreign object impedes rotation or the PF drive gears are damaged.
  Is the result OK?
  • Yes? – Inquire at Epson Service Support department.
  • No? – Remove the foreign object or Replace the damaged part.
