Precautions
1.3 ESD Precautions
Certain semiconductor devices can be easily damaged by static electricity . Such components are commonly called
“Electrostatically Sensitive (ES) Devices”, or ESDs. Examples of typical ESDs are: integrated circuits, some field
effect transistors, and semiconductor “chip” components.
The techniques outlined below should be followed to help reduce the incidence of component damage caused by
static electricity.
Caution >>Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
1. Immediately before handling a semiconductor component or semiconductor-equipped assembly , drain of f any
electrostatic charge on your body by touching a known earth ground. Alternatively, employ a commercially avail able wrist strap device, which should be removed for your personal safety reasons prior to applying power to the
unit under test.
2. After removing an electrical assembly equipped with ESDs, place the assembly on a conductive surface, such as
aluminum or copper foil, or conductive foam, to prevent electrostatic charge buildup in the vicinity of the assem bly.
3. Use only a grounded tip soldering iron to solder or desolder ESDs.
4. Use only an “anti-static” solder removal device. Some solder removal devices not classified as “anti-static” can
generate electrical charges sufficient to damage ESDs.
5. Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufficient to damage ESDs.
6. Do not remove a replacement ESD from its protective packaging until immediately before installing it. Most
replacement ESDs are packaged with all leads shorted together by conductive foam, aluminum foil, or a compa rable conductive material.
7. Immediately before removing the protective shorting material from the leads of a replacement ESD, touch the protective material to the chassis or circuit assembly into which the device will be installed.
8. Maintain continuous electrical contact between the ESD and the assembly into which it will be installed, until completely plugged or soldered into the circuit.
9. Minimize bodily motions when handling unpackaged replacement ESDs. Normal motions, such as the brushing
together of clothing fabric and lifting one’ s foot from a carpeted floor , can generate static electricity suf ficient to
damage an ESD.
1.4 Super Capacitor or Lithium Battery Precautions
1. Exercise caution when replacing a super capacitor or Lithium battery . There could be a danger of explosion and
subsequent operator injury and/or equipment damage if incorrectly installed.
2. Be sure to replace the battery with the same or equivalent type recommended by the manufacturer.
3. Super capacitor or Lithium batteries contain toxic substances and should not be opened, crushed, or burned for
disposal.
4. Dispose of used batteries according to the manufacture’ s instructions.

FUSER AC POWER CONTROL
Fuser(HEAT LAMP) gets heat from AC power. The AV power controls the switch with the Triac, a semiconductor switch.
The ON/OFF control is operated when the gate of the Triac is turned on/off by Phototriac (insulting part).
In other words, the AC control part is passive circuit, so it turns the heater on/of f with taking signal from engine control
part.
When the HEATER ON signal is turned on at engine, the LED of PC501 (Photo Triac) takes the voltage and flashes.
From the flashing light, the Triac part (light receiving part) takes the voltage, and the voltage is supplied to the gate of
Triac and flows into the Triac. As a result, the AC current flows in the heat lamp, and heat is occurred.
On the other hand, when the signal is of f, the PC501 is off, the voltage is cut off at the gate of Triac, the Triac becomes
off, and then the heat lamp is turned of f.

5. Disassembly and Reassembly
5.1 General Precautions on Disassembly
When you disassemble and reassemble components, you must use extreme caution. The close
proximity of cables to moving parts makes proper
routing a must.
If components are removed, any cables disturbed
by the procedure must be restored as close as
possible to their original positions. Before removing any component from the machine, note the
cable routing that will be af fected.
Releasing Plastic Latches
Many of the parts are held in place with plastic
latches. The latches break easily; release them
carefully.
To remove such parts, press the hook end of the
latch away from the part to which it is latched.
Whenever servicing the machine, you
must perform as follows:
1. Check to verify that documents are not stored
in memory.
2. Be sure to remove the toner cartridge before
you disassemble parts.
3. Unplug the power cord.
4. Use a flat and clean surface.
5. Replace only with authorized components.
6. Do not force plastic-material components.
7. Make sure all components are in their proper
position.

Service Manual
Solution
Possibly the parameters in PortThru are corrupted.Restart the system
and set to factory defaults on the printer front panel or on your computer
using SyncThru.
Try pinging from the same system on which SNMP manager is running.
If it does not succeed,there must be a problem with network connectivity
between the manager and PortThru.If ping succeeds,verify that community
names with sufficient permissions have been used.
Check the environment as described in Auto Detection of Print Server.
Check NetWare file server consoles for error messages regarding
nodes with conflicting network numbers.
On Network Interface in SyncThru,you should set “Static” to “IP Address
Assignment Method” in TCP/IP tab.You should set IP address,Subnet
Mask and Default Gateway to print server.
1.Check whether TCP/IP protocol is installed in your PC.
2.Check whether your PC is on the same network with print server .
Use SyncThru to see if PortThru indicates that queue is serviceable.
If not, the login permissions may have changed or the configuration
information for queues,printers and print servers may have been
changed. Verify using PCONSOLE and NWADMIN that the configuration
is correct and check the job queue to see if the print job exists. Check
that NetWare is enabled on PortThru.Check that the Check Job every is
configured on PortThru.
1.Check the protocol of your PC and install DLC/LLC or IPX/SPX protocol.
2.Assign IP Address to PortThru using the front panel.

But upgrading is not executed.
Solution
1.Verify that the printer power switch is turned on and the ‘READY’ message
is displayed on the printer front panel.
2.Verify that the LAN cable is plugged into the PortThru card.
3.Verify that the second LED on the PortThru card blinks.
•If the second LED blinks regularly,turn off the printer, then turn it back
on. If the problem continues,contact your local dealer.
•If the first LED on the PortThru card does not blink, check that the
card is installed snugly. If the problem continues, contact your local
dealer.
4.Confirm whether the print server and the PC which searches for the
New Print Server is on the same LAN. If you want to search for a New
Print Server,your PC and the print server should be on the same LAN.
Select the Network menu from the front panel menus. Check that the
test page is printed. If the Network menu is not displayed,or the test
page is not printed, turn off the printer, then turn it back on.
An IP address should be assigned to upgrade the Firmware.
Make sure that IP address is entered in Print Server.
If an IP address is not entered,reassign it and try again.

Troubleshooting
Problem
Solution
SyncThru is unable to automatically detect
printers.
1.Check LAN cable is connected to the printers.
•Check LAN cable is connected to the printers yourself.
•Make sure that there are the connected printers shown in network
neighborhood.If not, check the communication status of the printers.
•If IP address is assigned to the computers, try ping command.
2.If the protocols of NPC are disabled, DLC/LLC should be installed in
the computers.
•If SyncThru is unable to detect printers with DLC/LLC installed in the
computers, check whether NPC and PC are on the same LAN.
•If LAN is connected by routers, SyncThru is unable to detect the
printers.
3.If more than one of the protocols of NPC are enabled and DLC/LLC is
installed in the computers, check NPC and PC are on the same LAN.
•If LAN is connected by routers, SyncThru is unable to detect the
printers. In this case, one of protocols which are enabled in NPC
should be Installed in the computers.
4.In case that the protocol which is enabled in NPC is installed in the
computers:
•If TCP/IP installed, check entry values of IP address, subnet mask
and default gateway.
Try Add a Port.
The printer does not print.
