2.2 Printer Mechanism

Like the conventional model, this product uses DC motors and stepping motors as power sources. The following table describes the motor types and their applications.

		Table 2-1. Motors
Motor Name	Type		Applications/Functions
CR Motor	DC motor with		Used for carriage driving. Makes little noise during
			driving. The CR linear scale and CR encoder sensor
	brushes

2.7 Printer Initialization

There are four kinds of initialization method, and the following explains each initialization

1.Hardware 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

Initialization when resetting the USB software, and the following are performed.

(a)Clears input data buffer

(b)Clears print buffer

(c)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.IEEE 1284.4 “rs” command initialization

The printer recognized the IEEE 1284.4 “rs” command. When printer is initialized, the following action is performed.  Initialization when an error occurs.

(a)Initializes printer mechanism

(b)Clears input data buffer

(c)Clears print buffer

(d)Sets default values

Initialization in normal operation

(a)Clears input data buffer

(b)Clears print buffer

(c)Sets default values

3.1 Overview

This chapter describes unit-level troubleshooting.

3.1.1 Troubleshooting according to Error Messages

After checking the printer LED and STM3 error indications, you can grasp the fault location using the check list in this section. When you find the fault location, refer to Chapter 4 “Disassembly and Reassembly” and change the corresponding part and/or unit. The following table indicates the check point reference tables corresponding to the error states (LED and STM3).

Table 3-1. List of Error Messages

Error Status		LED Indications				STM3 Message	See the table for Troubleshooting
	Power		Paper		Ink
						Communication error
Communication error	-		-		-	Check all connections and make sure all devices are on. If the power was
						turned off during printing, cancel the print job. If the error does not clear,
							Refer to Table 3-2 ?Troubleshooting of Communication
						see your printer documentation.
							Error? (P.32)
Model Difference						Different device from specified
	-		-		-	Attempting to connect to a different device from that specified in the driver.
						Check the driver settings and the device.
Printer cover open	-		Flash		-	Printer cover open	Refer to Table 3-3 ?Troubleshooting of Printer Cover
error						Close the printer cover.	Open Error? (P.34)
						Paper out or not loaded correctly	Refer to Table 3-4 ?Troubleshooting of Paper Out
Paper out error	-		Light		-	Reload the paper, then press the Paper button on the printer or click the
						[Continue] button if it appears on the screen. To cancel the print job, click	Error? (P.35)
						the [Cancel] button if it appears on the screen.
Paper jam error						Paper jam	Refer to Table 3-5 ?Troubleshooting of Paper Jam
	-		Flash		-	Press the Paper button on the printer or click the [Eject] button when it
							Error? (P.37)
						appears on the screen. Remove any remaining jammed paper by hand.
						Page not printed or multi-page error	Refer to Table 3-6 ?Troubleshooting of Multi-feed
Multi-feed error	-		Light		-	A page has not been printed, multiple pages have been fed into the printer at
						once, or the wrong paper size has been fed into the printer. Remove and	error? (P.38)
						reload the paper. Press the Paper button if necessary.
