High 
Temperature
The print head is too warm.
Allow the machine to cool down.
Ink Empty
One or more of the ink cartridges 
is empty. The machine will stop all 
print operations. While memory is 
available, black and white faxes 
will be received into memory. If a 
sending machine has a color fax, 
the machine’s ‘handshake’ will 
request that the fax be sent as 
black and white. If the sending 
machine has the ability to convert 
it, the color fax will be received into 
memory as a black and white fax.
Replace the ink cartridges.

sure it is in the correct position. If the error 
remains, check the media drive by inserting 
another media card that you know is working.
Near Empty
One or more of the ink cartridges 
are running out of ink. If a sending 
machine has a color fax, the 
machine’s ‘handshake’ will 
request that the fax be sent as

machine has the ability to convert 
it, the color fax will be received into 
memory as a black and white fax.
Order a new ink cartridge. 
(See Ordering accessories and supplies on
