Hp 2055 57 fan error - HP LaserJet P2055d Printer

This appears to be a fan disconnection or malfunction.
It will need to be serviced by an engineer who knows the internals and can open the printer without damage.

1 Verify that the connector J65 on the dc controller is firmly seated. 2 Listen for the fan to operate while the MFP is initializing. 3 If the fan does not operate during the initialization sequence, replace it. See Main fan (FN101) and reversing-unit fan (FN103)

Hello Niramon,

The error message hp laserjet P3005n error 57.03 is due to sub cooling fan (FM2) error has occurred. Fan operation is verified during device power up. Fan operation occurs only during power up or during a print job.Turn the device off and then on. Verify that nothing is hindering or blocking the fan. Verify that the fan is connected to connector J512 on the ECU PCA. You might have to remove the main cooling fan to see this connection. If the message persists, replace the fan.

Hi


Error code 57.5 in HP 8150 means that printer fan error has occurred with the power supply fan. This issue can also be due to laser/scanner fan. Make sure both the fans are working perfectly fine. If the fans are fine, then the error is due to DC controller board.

To resolve this error turn off the printer for 4-6 hours (atleast 4 hours), this will reset the error. However, even after 4 hours you still can see the error then please check and replace the fan1 (power supply fan). Also, check for any burnt components on the dc controller board.

57.07 - Delivery-fan (back) error (fan #3). Reseat connections to the specified fan and DC controller. If the error persists, replace the specified fan. If the error persists replace the DC controller.

Error 57.1 means there is an problem with the fan. The fan is at the back of the printer, check that it's not blocked and/or reseat the cable connection into the pwb. If this doesn't work, replace the fan HP part number RH7-1552-000CN
