Problem with page cut-off

This information appears at the top of each document you send.

Registration ends and the fax returns to standby mode.

I don't know this exactly machine type.

Maybe you can get your answer here.

Yes, most likely your application's margin settings are incorrect. Try printing a test page - NOT from the application. If this is Windows, go to printers in control panel, right-click on the subject printer, choose Properties, then click the Print Test Page button. You should get the standard Windows printer test page with the logo at the top and all the printer specifics below. If the test page is also cut off, look around in the HP-provided software for any margin and/or page size settings that are incorrect, such as A4 paper when it should really be Letter size.

Most fax machines have to insert a name and time onto the top of the header of the page they send...this takes up a small amount of space therefore if you assume you page of information to be 100% then it has to be reduced slightly to allow this information header to be inserted on the page at the receiving end....the amount of reduction should only be down to about 95% but this is normal on all fax machines.

Function, 9, set options? press yes, code is model number (i.e. 9920} automatic reports/ press yes , Trasmit status report, press 2 for on. press yes, Image on report? press 2 for on, press yes, press STOP

I need more information. If you make 20 copies do you still notice the problem or only when you receive a fax. What is your copy count (press life 1). Does it jam or make noises. At first glance I would say phone line problem. .

check the cover if it has been closed properly, if not check the cover lock and hinges.

What is printed on the top of your received fax's is determined by the sending machine. If the user at the other end does not have name ,date and time programmed into their machine correctly then you will get printed on the top of your received page whatever is in their machine.

1 Be sure you have enough ink or film in your fax machine

1-either the paper is not picking up in time
2-you need to change setting or scale
