If you use the fax capabilities, make sure sufficient ink remains in the ink tank in advance. In addition, we
recommend you refill the ink tank early so that ink does not become insufficient while fax printing is in
progress. Visually inspect the remaining ink in the printer's ink tank.
Moreover, we recommend you check printed pages immediately after faxes are received. If a fax remains
in the printer's memory, you can reprint it after refilling the ink tank.
If [Do not print] is selected for [Received documents] on [Auto print settings] under [Fax settings] on the
operation panel of the printer, received faxes will not be printed immediately. Instead, faxes are stored in
the printer's memory automatically and you can select and print those stored from the printer's memory. In
this setting, the printer does not receive faxes if the printer's memory reaches its upper limit. Thus, stored
faxes are not overwritten automatically.
