[Changed Content]
Margin up for C59 (communications error)
z
The C59 error occurs, though extremely rarely, when a follow-up copy or print is made after a
previous copy or print due to the minute timing of the control of the beam position.
z
Margin up for CA2 (HSYNC abnormality), CA3 (secondary scanning adjustment error)
Noise affecting the beam control signal has been judged to be the cause of CA2, whereas
CA3 occurs on the production line.
To reduce the number of times these errors occur, noise countermeasures have been put into
place (improvement of control signal width).
