1.5.5 Printer Initialization
There are four kinds of initialization method, and the following explains each
initialization.
1. Power-on initialization
This printer is initialized when turning the printer power on, or printer recognized
the cold-reset command (remote RS command).
When printer is initialized, the following actions are performed.
(a) Initializes printer mechanism
(b) Clears input data buffer
(c) Clears print buffer
(d) Sets default values
2. Operator initialization
This printer is initialized when turning the printer power on again within 10
seconds from last power off, or printer recognized the -INIT signal (negative
pulse) of parallel interface.
When printer is initialized, the following actions are performed.
(a) Cap the printer head
(b) Eject a paper
(c) Clears input data buffer
(d) Clears print buffer
(e) Sets default values
3. Software initialization
The ESC@ command also initialize the printer.
When printer is initialized, the following actions are performed.
(a) Clears print buffer
(b) Sets default values
4. Power-on initialization except I/F
The printer recognized the IEEE 1284.4 “rs” command.

2.1.1 Printer Mechanism
The Printer Mechanism for the Stylus CX1500/ME100 is newly designed. But, the
basic component of the Printer Mechanism is almost the same as the previous printer
(Stylus C41/C42/C43/C44/C45/C46).
This printer consists of Print Head, Carriage Mechanism, Paper Loading Mechanism,
Paper Feeding Mechanism, Ink System.
Like the previous printers (Stylus C41/C42/C43/C44/C45/C46), the Stylus CX1500/
ME100 is equipped with two stepping motors; one for the Paper Loading/Feeding
Mechanism and the Pump Mechanism with the CR Lock Mechanism, and one for the
CR Mechanism. The ASF Unit for the Paper Loading Mechanism uses rear entry front
eject system. And, single LD Roller in Holder Shaft Unit loads a paper to the Printer
Mechanism.
