As the conventional models, Epson STYLUS NX100/NX105/SX100/SX105/TX100/
TX101/TX102/TX103/TX105/TX106/TX109/ME 300 is equipped with two DC
motors; one is used to drive the paper loading, paper feed mechanisms, and the pump
mechanism that includes the carriage lock mechanism, and another one is used to drive
the carriage mechanism. A paper is fed from the rear ASF unit by means of the LD
roller and Retard roller and ejected to the front tray.

3.1 Overview

This chapter describes how to solve problems.

 Be careful to avoid electric shocks when checking the electrical

circuit boards (MAIN and PSE/PSB boards) while the power is
turned on.

 Touching an FET, transistor or heat sink with one hand while

touching a metal part of the mechanism with the other hand
could result in an electric shock, so carefully avoid this.

 After initial filling of ink has been repeated several times,

immediate moving or tilting of the printer could result in
leaking of ink that has not been completely absorbed by the
Waste Ink Pad. When initial filling of ink has been repeated
several times, check the ink remaining in the tip of the Waste
Ink Tube and the waste ink not absorbed by the Waste Ink Pad
before moving the printer.

 Disassembly and reassembly of parts is often required when

identifying the causes of problems. The parts should be
disassembled and re-assembled correctly while referring to

“DISASSEMBLY/ASSEMBLY” (p.54) so that the operation

and status of each check item can be correctly verified.

 Some individual part and units may require adjustment once

they are removed or replaced. If removing or replacing parts
which have specific instructions for adjustment included in

“DISASSEMBLY/ASSEMBLY” (p.54), be sure to make these

adjustments after repairing the problem location.
