This slide attempts to explain the meanings of SP 2931 to 2936.
¾
As shown on the previous slide, the settings can be adjusted for each paper
tray.
ˆ
The settings are arranged in groups of four.
ˆ
The first group of four settings (La1, La1f, Lc1f, and Lc1) is for copying the front
side.
ˆ
The second group (La2, La2f, Lc2f, and Lc2) is for copying the rear side.
ˆ
The third group (La3, La3f, Lc3f, and Lc3) is for thick paper.
ˆ
The fourth group (La1, La4f, Lc4f, and Lc1) is for OHPs, and is for the by-pass tray
only.
ˆ
The example on the diagram shows the settings La1, La1f, Lc1f, and Lc1. The
other groups of four (La2, La2f, Lc2f, Lc2, and so on) are similar in style.
ˆ
The red rectangle in the diagram is a sheet of paper.
ˆ
On the slide, the La1 setting determines when the transfer current turns on before
the leading edge arrives at the transfer roller. The current for the leading edge area
is applied at this time.
ˆ
The La1f setting determines when the transfer current changes to the current used
for image transfer.
ˆ
The Lc1f setting determines when the transfer current changes to the trailing edge
current.
ˆ
The Lc1 setting determines when the transfer current switches over to the value
used between pages.
ˆ
SP2301 determines the actual currents that are used.
