New Additions To Transfer Current Control - Gestetner A294 Service Manual

1.7 NEW ADDITIONS TO TRANSFER CURRENT CONTROL

With the adoption of the new toner, the transfer current for the leading edge has
been decreased to further ensure that separation pawls do not leave marks on
copies. Compared to the 2 predecessor A294 I / A295 I models, this can have the
effect of slightly reducing the image density in solid image areas 10mm from the
leading edge (no effect on text and halftone). However, since this tends to occur
with certain types of paper (relatively smooth but not stiff), a new SP mode
(SP2940) has been added so that the leading edge transfer current can be set
individually for each paper feed tray.
Since OHP transparencies and thick paper have a relatively high stiffness and are
therefore not prone to pawl marks, leading edge transfer current control is disabled
when either of these paper types is selected in User Tools. Also, an additional SP
mode (SP2941) has been added so that leading edge transfer current control can
be performed (or not performed) when using semi-thick paper with which the
duplex and punch modes can be selected. In order to do this, please select "Thick"
in SP2941 and "Recycle" in User Tools.
Please use SP2941 when the leading edge transfer current for semi-thick paper
seems to be insufficient. The machine will then treat the paper the same as if it
were thick paper. Note that if "Thick" were selected in User Tools, the machine
imposes functional restrictions (cannot use duplex, punch-hole, etc.).
