Appeal No. 2001-1336
Application No. 08/736,042
BACKGROUND
Appellant’s invention is directed to an image forming
apparatus and a method for adjusting the transfer voltage for
optimizing image density according to the path a sheet of
recording media takes. The path depends on the tray the sheet of
recording media originates from such as an automatic feeding
cassette and a manual feeding tray (specification, page 5). When
a sheet of recording medium is fed through the manual tray and is
conveyed toward the image forming unit, a sensor is triggered
(brief, page 9) and a signal is generated by an engine controller
(brief, page 10). This signal indicates that the recording
medium has a thickness greater than the standard thickness and
the transfer voltage should be adjusted accordingly (id.).
Representative independent claim 1 is reproduced below:
1. An image informing apparatus using an
electrophotographic developing system, comprising:
a photosensitive drum positioned along a path for
conveyance of articles of recording media through said
system;
a manual paper feed tray attachable to said system
while introducing the articles of recording media onto said
path via a first avenue;
a cassette associated with said system to introduce
other articles of recording media onto said path via a
second and different avenue;
