5.4.3 LASER BEAM PITCH ADJUSTMENT
There are two laser beam pitch adjustment procedures: one for 400 dpi, and one
for 600 dpi. These adjustments use the following SP modes.
· SP2-109-1: Laser Beam Pitch Adjustment – 400 dpi
· SP2-109-2: Laser Beam Pitch Adjustment – 600 dpi
· SP2-109-3: Laser Beam Pitch Initial Setting – 400 dpi
· SP2-109-4: Laser Beam Pitch Initial Setting – 600 dpi
· SP2-902-2, no.12: IPU Test Pattern – Cross Stitch – 400 dpi
· SP2-902-2, no.13: IPU Test Pattern – Cross Stitch – 600 dpi
1. Perform SP2-109-8 (Beam Pitch Data Reset).
2. Input the value for 400 dpi that is printed on the LD unit into SP2-109-1.
Use the value printed after “P” on the new LD unit as shown below.
NOTE: Do not use values printed after a “V”.
3. Press the “Enter” key.
4. Perform SP2-109-3.
5. Print the 400-dpi test pattern onto A3 (11”x17”) paper using SP2-902-2 no.12
(cross stitch). (See Service Tables - Test Pattern Printing).
6. Write the value of SP2-109-1 on the test pattern which was input at step 2.
7. Change the value of SP2-109-1 and print another test pattern, repeating steps
2 to 5. Print about 5 patterns with different values for SP2-109-1 (e.g. “48”, “96”,
“192”, “240”).
8. Check this test pattern. If the laser beam pitch is not correct, the image looks
like a black vertical stripe pattern.
NOTE: If the laser beam pitch is correct, the vertical stripe is not so noticeable.
If the value is not correct, the vertical stripe pattern is darker.

9. Adjust the laser beam pitch position until the thin lines are of uniform thickness
(no striping effect should appear on the printout), doing steps 2, 3, and 4. (In
step 2, input a value which is estimated to be correct, then do steps 3 and 4,
then if necessary go back to step 2 and try another value.)
10. After adjusting the laser beam pitch for 400 dpi, adjust the laser beam pitch for
600 dpi, using the same procedure as for 400 dpi (use the SP modes for 600
dpi).
