10. The weight limit of the original table is 5 kg (11 lb.). To avoid damaging the original table, never
lean on the original table and never place anything on the original table when you are working
around the machine.
11. To avoid damage to the exposure glass below the cover or the white plates attached to the
underside of the cover, always check the original path before you close the scanner cover.
12. If anything falls into the machine that the operators cannot recover, they must call for service.
Foreign objects in the machine could cause a short (which can lead to a fire), or could cause feed
problems.
13. During feeding of a thick original (90 g/m
2
), the side guides could skew the image and cause
parts of the image to disappear at the points where the CIS elements join. In such a case, use the
white lines on the original table to guide the original during feeding.
14. When feeding a thick original (180 g/m
2
), do not push the original after it strikes the original feed
roller and starts to feed. The original feed roller has a one-way feed clutch. If the original is pushed
in the direction of the leading edge, this could buckle the original and cause it to jam at the original
registration sensor.
15. Originals up to 135 g/m
2
can exit to the original stacker on top of the machine. Thicker originals
must feed straight through and exit the back of the machine. Removal of the original exit guide on
top of the machine allows the originals to exit straight out the back.
16. Also, use straight-through original feed for thin or flimsy originals. For example, tracing paper (80
g/m
2
or less), or normal paper (52.3 g/m
2
or less). Buckling of thin or flimsy paper can lead to
accordion jams and damage the original.
Paper
1. Always set the roll (or start paper feed) from the bottom of the roll, not the top. Feeding paper from
the top of the roll places an excessive load on the paper feed rollers and could cause problems
with paper feed and cutting. Also, feeding the paper from the top sets the paper against the
direction of paper curl, which causes the paper to lift and rub against the print heads leading to
poor copy quality and damage to the print heads.
2. If the machine is to remain idle for a long period where the temperature and humidity are high or
low, remove the paper rolls from the machine and store them (in their original packing if possible).
If the rolls cannot be removed and stored, then before the machine is used again, feed the leading
edge of the roll about 1,000 mm (39 in.), and then cut it off.
Copy Quality
1. Photo images that have areas filled with dithering or fine lines frequently exhibit moiré.
2. Even for images where moiré does not stand out with 1:1 copying, changing the rate of
magnification could cause moiré to appear.
