MFP M477fdn fails with 59.F0 error when printing in black and white (colour printing works fine)

[Thack_1]

Just installed my brand new MFP M477fdn.

It prints colour documents fine.

However, if I tell it to "Print in grayscale", it fails.  The same happens if I tell it to "Print all text as black".

Also, most of the Setup | Reports won't print - only the ones that use colour (Demo Page and Supplies Status) will print, all the others (which print black text only) fail.

In every case the failure is the same: it display a warning triangle with the following text:

59.F0 error

Turn off then turn on.

Clearly something is badly wrong.  Can anyone advise?  Is it something I might be able to fix myself?  If not, will HP repair it for me, or must I sent it back to the seller (an Amazon seller)?

Thank you!

Looks like nobody is familiar with this one.  According to the service manual it requires a drum motor change, although I'm sceptical as it works fine for printing colour pages.

Anyway, I'm sending it back for a refund and have bought another.  This post is to close the thread.

This 59.F0 error is typically the result of a small sensor switch inside the ITB (Intermediate Transfer Belt) assembly that is not working correctly. It will have variable amounts of resistance as it is activated during the course of operation and causes the error. It's supposed to detect and report to the controller when the plates are moved into position to press the belt into contact for the toner cartridge drums for color printing. HP came out with a new version of firmware for the DC Controller board to ignore this shortly after I brought it to HP's attention awhile ago since we were having so many issues with customer printers. The previous fix was to replace the ITB assy., which worked most of the time, but the firmware update should be tried first as it is quick and simple and we've had great success with it so far.

Here's the HP FTP site for it:

That's amazing - thank you!

In fact the Amazon vendor had sold me a faulty, secondhand printer and gave me a refund.  I bought a new one from a different vendor and the replacement has worked perfectly.

Nevertheless, I've downloaded the software patch and instructions, in case the fault appears on mine.

Thank you again.
