Print Density Dial
The Print is too Light or too Dark
The print density dial is located in the
corner under the top cover. (Remove
the drum unit assembly.) You can use
it to adjust print density by increasing
or decreasing the Print Density function
setting you chose.
The print may become darker or lighter
as conditions change (such as changing
the toner cartridge eind drum unit or if
the MFC has become overheated from
heavy use).
Use a straight blade screwdriver to turn
the print density dial clockwise for darker print and counterclockwise for lighter print.
The dial has
been set to the middle position.
Make five or six copies to bring the toner up to the level of the new setting.
If the piiut is stdl too light, check to see if the Toner Save feature is ON (see page 72).
Received Faxes Appear as Split or Blank Pages:
If the received data is divided and printed ou 2 pages or if _ y o u get an additional blank
page, your Paper Size setting may not be correct for the paper you are using (see page
68). If you are using the fixed reduction feature, check to see if the reduction ratio is
suitable for the real recording paper (see pages 69-70).
When Dialing Doesn’t Work...
You may have the wrong dialing mode. Change the TONE/PULSE setting. (Seepage21.)
You should check all the telephone line connections (such as to the handset and to the wall
jack). Check also that the power cord is connected and the power switch is turned on. (See
page 9 of Setup Manual for Fax, Printer, Copier.) Check by pressing Hook to see if you
hear a dial tone. Also try dialing by first pressing Hook or lifting the handset. Wait until
you hear the fax tones and then press Start.
MFC Does Not Answer When Called:
Make sure the MFC is in the correct receiving mode for your setup (either Fax,
F/T or MSG CTR). Check for a dial tone. If possible, call your MFC to hear it answer.
If there is still no answer, check the telephone line cord connection. Connect a
standard telephone handset to the MFC telephone jack. If there is no
ringing when
you call your MFC, call your Telephone Company to check the line.
No Dial Tone on the Handset:
Press Hook. If you don’t hear a dial tone, check telephone line cord connections at
MFC and wall jack. Check that the handset is connected to the MFC’s handset jack.
Test the wall jack with another single line telephone. If no dial tone on the wall outlet,
call your Telephone Company.
