B
Vertical uneven print
density and lines.
<Supplement>
Uneven print density due
to the scan complement
control** performed at
print data break-up.
-When a low specification
performance computer is used
-When other applications are
running
-ROM version 1.00
<Supplement>
Among special papers with large
amount of print pattern data.
Note: Comparably remarkable in
the specific print pattern (a
uniform pattern using single
color)
When scan overflow control fails, the scan
complement control** is performed at the
same position repeatedly, thereby uneven
print density and lines appear. (While this
phenomenon occurs, the print s peed
slows considerably.)
<Permanent countermeasure>
Rectified in ROM version 1.30 onwards.
1. Close the other
applications.
2. Upgrade the ROM
from 1.00 to 1.30
onwards.
-Lines/uneven print density at the
top edge of paper
-Cannot print properly
12
C
Horizontal uneven print
density and lines at the
trailing edge of paper
<Supplement>
Problem appears within
about 30mm from the
trailing edge.
-When borderless printing is
conducted.
-When printing is conducted in
“Full” to the printable area’s
trailing edge.
Note: Comparably remarkable in
the specific print pattern (a
uniform pattern using single
color)
When the paper end comes off the pinch
roller, the paper is printed without being
held, preventing the ink drops from being
ejected in the correct positions, resulting
in unevenness.
Note: The problem is more severe than
that of the S200.
Recommend printing in
the print quality
assurance area.
-Cannot print to the bottom edge
of paper
-Lines and uneven print density
appear in the trailing edge of
paper
-Cannot print properly
13
Horizontal lines and
uneven print density due
to LF roller feeding at
small pitch.
<Supplement>
Lines and uneven print
density of 1 to 2mm
pitches.
Special paper / standard mode.
<Supplement>
Paper of PR series, SP101.
Note: Comparably remarkable in
the specific print pattern (flesh
tones and a uniform pattern
using a single color)
As the print media slightly slips against
the feeding amount by the LF roller,
printed areas overlap, causing the
problem.
Change the print quality
from standard to high
mode.
-Lines and uneven print density
(on flesh tones and background)
-Cannot print properly
14
Horizontal white lines
and gaps due to LF
roller.
When monochrome printing is
conducted to the plain paper in
the standard mode.
<Supplement>
Note: Comparably remarkable in
the specific print pattern (black
halftone graphic pattern).
The print media is slightly overfed against
the feeding amount of the LF roller,
causing white lines (missing) to appear.
<Permanent countermeasure>
The printer driver has been upgraded.
1. Change the print
quality from standard to
high mode.
2. Upgrade the printer
driver.
Win98/Me: 7.31 onwards
Win2000/XP: 1.61
onwards
MacOS8.6 and later: 4.11
onwards
-Print head path lines and
uneven colors
-Cannot print properly
*Rank
A: The phenomenon may occur at a relatively high occurrence ratio. (Caution needed)
B: The phenomenon may occur in specific conditions, however the occurrence ratio is expected to be considerably low in the actual usage.
C: As the phenomenon is hard to be recognized by general users, it is expected to cause no claims from the users.
**Scan complement control
