EPSON Stylus C82

3.1 Overview

This chapter describes how to troubleshoot problems.
Be careful to avoid electric shocks when checking the electrical
circuit boards (C486 MAIN, PSE and B circuit 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
"Chapter 4 Disassembly and Assembly" 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
"Chapter 4 Disassembly and Assembly", be sure to make these
adjustments after repairing the problem location.

3.1.1 Troubleshooting With LED Error Indications

3.1.1.1 Paper Out/Double Feed Error

Is the PE Sensor disconnected from the Main Board?
Is the PE Lever properly operating?
TROUBLESHOOTING

3.1.1.2 Ink Out

The Ink Out indicator did not recover immediately after installation of the Ink
Cartridge. Press the Ink Switch and the Ink Out indicator will go out after the
Carriage Unit returns to the HP. (Use same procedure for Ink Low after installing
other Ink Cartridge.)

3.1.1.3 Fatal Error

There are 3 types of Fatal Errors: Carriage Error, PF Error and Head Hot Error.
1. Press the Power Switch, then turn on power again. (If it does not recover, see
Table 3-1.)
Table 3-1. Carriage Error and PF Error Check Points
<Situation>
• Does the CR Motor turn?
• Does the PF Motor turn?
2. Possible Head Hot Error Verification
Before eliminating the cause of the Error, use Adjustment Program to check
EEPROM 2Dh error history.
2Dh → 0Dh
: Indicates that Head Hot Error was generated for black
2Dh → 0Eh
: Indicates that Head Hot Error was generated for color
1. Ink Out is not activated by Head Hot Error.
2. Automatic cleaning starts next time power is turned on.
3. Head Hot Error (Fatal Error) is generated only when a large
quantity of Dot Missing is generated.
