4ppm when copied meeting with the following conditions;
(1) Resolution: Fine
(2) Scale: 100%
(3) Print duty: 50% or less
*standard chart: ITU-T No.1 (Refer to ITU-T No.1 TEST CHART (P.162).)
(i) Print Duty 50% or less
The sequence is shown on TIMING CHART (P.131).
When print duty is 50% or less, IC520 pin 44 and 45 (NEWSTB1/NEWSTB2) are composed IC501 pin 103 (STB1) and
IC501 pin 104 (STB2). (logic-AND)
[Print speed of one-line: 4.608msec]
(ii) Print Duty more than 50%
The sequence is shown on TIMING CHART (P.131).
When print duty is more than 50%, IC520 pin 45 (NEWSTB1) and IC501 pin 103 (STB1) are the same signal.
[IC520 pin 44 (NEWSTB2) and IC501 pin 104 (STB2) are the same signal.]
[Print speed of one-line: 4.608msec x 2 = 9.216msec]
