rotation speed (Printer))
<Procedure>
(1) Performs FS-05.

(05 Adjustment Mode)
(2) Press [1]

[TEST PRINT]. (A grid pattern with 10 mm squares is printed out. Use A3/LD from
the lower drawer (Refer to *).
(3) Check the grid pattern on the test chart printed out and measure the distance A from the 1st line
to the 21st line of the grid pattern.
(4) Check if the distance A is within 200±0.5 mm.
(5) If not, use the following procedure to change values and measure the distance A again.
FS-05

Key in code [4001]

[START]

(Key in a value (acceptable values: 0 to 255))
