miss-feed.
Furthermore, the machine does not have a paper size detection sensor so it detects the
paper size by on-off timing of the input sensors. . If the paper size detected in this way
and the paper size loaded in the tray are different, the paper jam is to occur.
Component Layout in Duplex Unit
Duplex unit consists of the below 4 components and the role of each part is as the following.
1) Upper body : As the main function it plays a role of upper rib for good papaer path,
and, there is a roller installed to correct some skew.
2) Front body : It plays a role of guiding the paper on the paper reverse area(lower
part) to go up to EP frame(upper part), and supports the base body with a fixture
using a spring.
3) Base body : It corrects skew of the paper by 3 rollers installed so that the leading
edge of the paper(A4 or Letter has no difference) can be printed out in parallel.
4) Jam remove cover : When a paper jam occurs in duplex system, it opens the
paper path to remove the jammed paper easily.
