Error code 00893947 on HP OfficeJet G85

Hello everyone,

I have an HP OfficeJet G85 Multifunction center that will not send or receive faxes. The machine will simply not answer a fax call but generates no visible errors. When an attempt is made to send a fax the following occurs as soon as the send button is pushed:

the console lights (all green LED's) blink on and off in unison and very rapidly. The small LCD display shows the following message: Error 00893947.

Here are some other pieces of information: This location uses distinctive ring to receive faxes on the same telephone line. This has been set up correctly and has worked for the past two years until just recently when the machine seems to be having problems.
This location has verizon dsl. A proper dsl filter has been installed on the multifuction unit and on all other telephone lines at this location. Again, this has been set up correctly and has been working for the past two years until recently.

I have made attempts to contact HP for some suggestions on how to solve this problem. I think we are all aware of what a waste of time that is.

Thanks again for any help or suggestions as to what this could be.

I can only think of 2 things.  Almost all HP faxes/all-in-ones have a temp sensor near the scanner bulb.  A common problem with Officjet printers is the sensor goes bad, so the printer thinks the bulb never attained a stable output, so errors out, but usually give a real error, not just a number.  The second would be that the controller board inside is bad, and would have to be replaced, but would be cheaper to buy a new printer probably.

Hi Purple_Tidder,

If the problem were the temp sensor near the scanner bulb, do you think that the unit would be able to print and copy normally?

Also, if the conrtroller card was bad, would that tank the printing and copying functions, or just the faxing functions?

This error only seems to occur during fax send or receive operations.

Thanks,

Well, no.  If it was a scanner bulb/temp error, the whole unit stops working.  Even if you send a print job to it from a computer, it wouldn't print.

Hmm, that clarifys it a bit.  I was under the impression the whole thing wouldn't work.  I wonder if I can get my hands on a repair manual for that particular printer.  Let me check and I'll get back to you.

Well, I've checked everywhere, and I don't think a repair manual exists.  If you can wait till monday, I'll give my printer parts supplier a call and just make absolutely sure about the repair manual. I can't even find any information about that particular error either.  Strange.

Actually, I've found something.  Give this a read.  Run an extended self test report.

I believe I have your answer.  I was talking to a buddy of mine that had the same problem, and as he recalls, same error.  He replaced the modem inside his printer, and now all is well.  Hope this is your answer.

After some more research, it's not called a modem.  It's called the fax module assembly, and it's part number is C6735-60001

It's cost direct from HP is $39.00 plus shipping.

Here's a link, but I'm not sure if it will work.

I saw the strangest thing when I opened up the back of the machine near the fax module assembly.

There were two parts behind the cover:

1. the fax module assembly(what the phone line plugs into)
2. some kind of unknown (to me) device the that fax module plugs into, I shall call it "part b" which in turn, plugs into the printer(or controller card, I'm not sure which)

There is a small screw that holds "part b" on to the printer. The screw had somehow become removed from it's place and the unit, including the fax module assembly had pulled away from it's connector and fallen into the cavity created by the back cover. Additionally, the fax module assembly had dislodged from it's cheeseball (in my opinion) connection to "part b" and was simply "floating" around in the back of the mfc. Now how this thing continued to work for as long as it did, I will never know. I keep thinking that this device had to suffer some kind of blunt trauma at some time in it's not-too-distant past.

In any case, reconnecting "part b" to it's connector, returning the screw to it's rightful place and plugging the fax module assembly back into "part b" solved the problem. I was glad to have the parts and troubleshooting info provided by Purple_Tidder. I was ready to order a new part before I discovered the chaos that lurked behind the back cover of the mfc.

Thanks Purple_Tidder for the tremendous help.

Cheers,

Just a little further insite, the part you are referring to as "Part B" I think is actually the fax modue.  The part that the phone line plugs into is called the LIU or Line Interface Unit.  It plugs into the fax module, which in turn plugs into the main board.

Thanks for the points! Much appreciated!
