Step

Checks

Is ‘E020’ for the SALT sensor?
Detailed code XXXX

↑−

Numeral: SALT
sensor
Alphabet: toner
density sensor

Replace the toner density sensor of
the color for which ‘E020’ is indi-
cated. Is the problem corrected?

Is the front cover open while the
transfer frame front cover is removed
(i.e., is the SALT sensor subject to
stray light)?

Replace the photosensitive drum. Is
the problem corrected?

Yes/No

YES

Action

Go to step 7.

End.
• Be sure to replace the

developer after replac-
ing the toner density
sensor.

Replace the DC controller
PCB.

Install the transfer frame
front cover.

Replace the SALT sensor.
• Be sure to replace the

developer after replac-
ing the toner density
sensor.

End.

Replace the DC controller
PCB.
