FINAL CHECK
o
Check the auto cutter's paper cutting position.
•
Set the paper at about 10 cm below the level difference where paper is cut
by the paper cutter, then release the CR unit lock manually and move it to
the center of the paper.
Pierce the paper with the paper cutter manually, then cut the paper on the
left and right. Confirm that the length from the cut edge of the paper to the
level difference edge for the cutter on the sub-platen is within 0.5 mm _
0.2. For details, see page 207. If it is outside the standard, the necessary
adjustments should be made.

depending on the firmware version.)
n Waste Ink Counter
Compare the counter value from the time this operation was being
prepared for, with the counter value when the nozzle check pattern
was printed out. Confirm that the value has gotten smaller.
NOTE: If initial filling has been exceptionally performed several times
during this operation, the counter value that is printed out may
actually be higher than the value printed out during the
preparations.
Disassembly & Assembly
n Vertical Nozzle Alignment Check Pattern
In this pattern, it should be confirmed that no irregular color (dark
portions, light portions) are occurring in the patterns of each color. If
extreme color irregularities are occurring, carry out KK2 Cleaning in
the Self-diagnostic mode, and check if it recovers. If it doesn't recover,
replace the heads.
n Horizontal Nozzle Alignment Adjustment Pattern
Confirm that there is no missing of dots and that there is no ink
scattering in the horizontal direction, deviation, etc.
n Left Head Slant Adjustment Pattern
The Magenta and Black patterns should be arranged on the same line
horizontally.

The Light Magenta and Light Cyan patterns should be arranged on the
same line horizontally.
n Head Height Adjustment Pattern
The Light Magenta and Cyan patterns should be arranged on the same
line horizontally.
n Bi-D Adjustment Pattern (Adjustment Results, #1 ~ #4)
Patterns #1 ~ #3 should line up along the same vertical line.
For #4, the 8 patterns in each color should be checked for a block
pattern with no overlapping and gaps. Recheck with another check
pattern.
n Head Gap Adjustment Pattern (Adjustment Results #5, #6)
Patterns #5 and #6 should line up on the same vertical line.
o Bi-D Pattern #4 Check
Start Pout3.exe from the DOS prompt, the transfer the Bid333.Prn file to the
