[Error Code] HP LaserJet M477fdw error: "The product is unable to calibrate. Close the lid and

[Guest]

This is a Color LaserJet Pro MFP M477fdw , serial number is VNB8JBN44W , mfg. date 10-21-2016.


The printing mechanism works fine (it prints out the "Wireless Network Test Report").
But when the printer is powered on, the screen shows the error message:

The product is unable to calibrate. Close the lid and remove paper from the document feeder or flatbed.

Steps taken so far:

• Followed steps for clearing paper from the ADF and flatbed (per Contact HP Customer Support | HP(R) Customer Support... )
• Followed steps to hard restart the printer
• Reset the printer to factory defaults
• Connected printer to wifi
• Current firmware is 20160331. Attempted firmware update using HP LaserJet Pro Series Windows Firmware Update Utility (20190113)... but update would not complete, I believe due to the error message on printer.
• Attempted firmware update using printer's settings menu -> wireless setup menu... but update would not complete, I believe due to error message on printer.
• Following the procedure on page 569 in the MFP M377 repair manual, "Removal and replacement: Integrated scanner assembly", removed the Scanner/ADF unit and reinstalled it, checking for any broken cables. The ribbon cables do not appear broken or kinked.

First question: what is the next step in solving this problem? Mechanically, the printer seems fine, but it is unusable until we solve this problem. This printer sells at Staples for $369... do we have to throw it in the trash, or is it fixable?

1a. If we must replace the entire ADF, what is the most economical way to obtain a replacement (does anyone have a recommended source for a used part?)


Second question: If it is not possible to fix this problem with the ADF, is it possible to remove the scanner/ADF unit altogether and use the printer as if it were an M452 ? What would be the procedure for this?

5 years later and I just noticed this thread cause I had the same problem. Turned out to be the ribbon cable between the main board and the doc feeder. Yes, the feeders are removable, but you should be able to use it just as a printer without doing all that.
