Troubleshooting
When the fax board cannot receive a fax
The fax board has a 300KB buffer that allows it to store fax data
when it can receive but not print. It can store up to 15 pages
depending on the amount of text and graphics on each page.
For example, it uses the buffer when it receives a fax while it is
printing a standard print job sent by your computer.
The fax board cannot, however, receive a fax under the
following conditions:
o When the buffer is full
o When the printer is off line
o When the phone line is already in use
o When the printer is turned off.
The fax board cannot begin reception if the printer is off line
before the fax data starts arriving, but it can continue reception if
the printer is taken off line after the board begins receiving a
fax.
Printer error
The fax board can receive fax data until the data buffer is full
under the following conditions:
0 Paper out
Toner out
0 Paper size error
0 Paper jam
0 Cover open
