[Check Items]

• Check the pattern to see if the laser output of LD1/LD2 is uniform with the gradation continuously repro-

duced.

[Recommended checkpoints]: Write unit, and LD1/LD2 offset adjustment

For LD1/LD2 offset adjustment, see “1. Process adjustment”.

Since a single beam is employed for 7235/7228/7222, the pattern shown as LD2 in the illustration

below is also output by LD1.
