1.1 Overview
This section describes the specifications for the SPC (Scanner, Printer, Copier)
machine “Stylus CX3100/3200”.
Reduced (Minimize) Margin Copy mode
This mode is basically the same as the standard copy mode, but the bottom
margin is 3 mm.
Repeat Copy mode
1.1.1 Basic Functions
The functions of Stylus CX3100/3200 are as described below:

depth is 48-bit at the ADC output, 24-bit when passing to a PC.
Standalone Copier function
The Product has the Standalone Copier function that reproduces photo quality
copies on the Epson special coated papers without PCs. The use of the latest print
technology mounted on the Product achieves the highest standalone copy speed
among the same class of the products.
Standard Copy mode
This mode is used for the standard copier function. The bottom margin is 14
mm.
BorderFree Copy mode
Photograph copy
Small Margin Copy mode
The minimum copy margin is 1.5 mm.
Mini photo stickers can be produced.
2-up Copy mode
Two pages of the original is shrunk and printed on one page. Consumption of
copy paper can be saved.
Mirror Copy mode
The original can be flipped from left to right and copied onto the Iron-on Cool
Peel Transfer Paper.

(2)If paper is stopped midway, pull paper
out and check that paper is not folded.
Loosen paper well and set it again with
edge guide adjusted to paper width.
(3)Execute “Load/Eject”.
• Clean paper loading roller. Or replace
paper loading roller.
• Check that gears for ASF are engaged
correctly.

adequately to feed paper by
the required distance.
• Select “Load/Eject” from menu and
execute it.
(1)Open the printer cover and remove
with hand all the paper inside the
printer and all the set paper if there is
paper on the way of loading.
(2)Check that there is no paper in the
printer and set paper again and execute
paper loading and paper ejection.
Then, this error display will be cleared
and if there is print data, print
operation will start.
• Check whether Platen gap is correct
value. (Refer to “Adjustment” on
page 57)
• Check CSIC connection circuit.
• Replace ink cartridge.
After replacing waste ink porous pad,
reset waste ink overflow counter. (Refer
to “Protection Counter” on page 69)
• Several seconds or more after turning
power off, press power switch to turn
power on.
• Open maintenance cover and check
that there is no obstacle in the carriage
moving zone.
If the error is not cleared even by the
above operation, check the followings:
• CR HP sensor/Harness
• CR Lock mechanism
• Main board
