Figure 2-26 shows the basic sequence for the paper feed motor.

●

Rtl

When the printer power is turned on, the paper feed motor is rushed for 30 to 60 ms in any phase.

It takes 25 ms for the paper feed motor to restart from the stop mode. And after that, the paper feed

motor rotates both back and front for each 16 steps to fix the back-rush between the motor pinion

and gears.

● Acceleration mode

The acceleration mode consists of a maximum of four steps, and the phase switching time for each

step becomes shorter as the step number increments.

● Constant speed mode

After the acceleration completes, the motor enters the constant speed mode. The time period for

each step is the same, 2.03

ms.

. Deceleration mode

The deceleration mode consists of a maximum of 12 steps, and the phase switching time for each

step becomes longer as the step number increments.

●

Rt2

When the paper feed motor decelerates and stops, it enters the holding mode after the rush time

of 15

ms.

The paper is fed 1/6 inch (4.23 mm) per 36 steps. When the total number of steps is 10 or less, the

paper feed motor is driven only in the constant speed mode, but with a step time of 3.28

ms.

The phase

switching pattern and time data are contained in the working area of the RAM. The CPU outputs the

data to the E05A03 the number of times specified by the program.

2.4.6.3 Auto Loading Function

The sequence for the auto loading function is shown below.

1. The printer moves the carriage to the 40th column.

2. The printer drives the paper feed motor for 433 steps to load the paper.

In this way, the printing start position is set approximately 22 mm from the top of the paper.
