Epson EPL-6100 Installation Guide

This printer uses laser technology. Follow the precautions below to ensure safe, 
efficient operation.

❏ Be careful not to touch the fuser, which is 

marked CAUTION Hot Surface Avoid 
Contact. If the printer has been in use, the 
fuser can be very hot.

❏ Do not attempt to modify or take the developer 

cartridge apart. It cannot be refilled.

❏ Do not touch the toner and avoid all toner 

contact with your eyes.

❏ Do not dispose of used developer cartridges 

and photoconductor units in fire, as they can 
explode and cause injury. Dispose of them 
according to local regulations.

Read all of the following instructions before operating your printer:

❏ Follow all warnings and instructions marked on the printer.

❏ Unplug this printer from the wall outlet before cleaning. 

❏ Use a well-wrung cloth for cleaning and do not use liquid or aerosol cleaners.

❏ Avoid touching the components inside the printer unless instructed to do so in 

this guide.

❏ Never force printer components into place. Although the printer is designed to 

be sturdy, rough handling can damage it.

❏ Be sure to keep consumables out of the reach of children.

❏ Do not leave jammed paper inside of the printer. This can cause the printer to 

overheat.

❏ Do not use this printer near water.

❏ Do not place the printer on an unstable surface.

❏ Do not put your printer where the cord will be stepped on.

❏ Avoid using outlets that other appliances are plugged into.

❏ Slots and openings in the cabinet and the back or bottom are provided for 

ventilation. Do not block or cover them. Do not put the printer on a bed, sofa, 
rug, or other similar surface or in a built-in installation unless proper ventilation 
is provided.

❏ Use the type of power source indicated on the label. If you are not sure of the 

type of power available, consult your dealer or local power company.

❏ If you are unable to insert the plug into the outlet, contact a qualified electrician.

❏ If you use an extension cord, make sure that the total of the ampere ratings on 

the products plugged into the extension cord does not exceed the extension cord 
ampere rating.

❏ Never push objects of any kind through cabinet slots as they may touch 

dangerous voltage points or short out parts that could result in a risk of fire or 
electric shock.

❏ Never spill liquid of any kind on the printer.

❏ Except as specifically explained in this guide, do not attempt to service this 

product yourself. Opening or removing those covers that are marked 
Do Not Remove may expose you to dangerous voltage points or other risks. 
Refer all servicing in those compartments to a qualified service representative.

❏ Adjust only those controls that are covered by the operating instructions. 

Improper adjustment of other controls may result in damage and may require 
repair by a qualified service representative.

❏ Unplug this printer from the wall outlet and refer servicing to a qualified service 

representative under the following conditions:

Your printer is a Class 1 laser product as defined in 
the IEC60825 specifications. 
The label shown is attached to the back of the 
printer in countries where required.

The EPSON EPL-5900/EPL-6100 is a page printer 
which utilizes a semiconductor laser.

There is no possibility of danger from the laser, provided that the printer is operated 
according to the instructions in the guides provided.

Since radiation emitted by the laser is completely confined within protective 
housings and external covers, the laser beam cannot escape from the machine during 
any phase of user operation.

w

This is a semiconductor laser. The maximum power of the laser diode is 5 m

W and 

the wavelength is 770 to 810 (EPL-5900) / 795 (EPL-6100) nm.

This is a Class III b Laser Diode Assembly that has an invisible laser beam. 
The printer head unit is NOT A SERVICE ITEM, Therefore, the printer head unit 
should not be opened under any circumstances. An additional laser warning label 
is affixed to the inside of the printer.

A. When the power cord or plug is damaged or frayed.

B. If liquid has been spilled into it.

C. If it has been exposed to rain or water.

D. If it does not operate normally when the operating instructions are followed. 

Adjust only those controls that are covered by the operating instructions 
since improper adjustment of other controls may result in damage and will 
often require extensive work by a qualified technician to restore the product 
to normal operation.

E. If it has been dropped or the cabinet has been damaged.

F. If it exhibits a distinct change in performance, indicating a need for service.

Food and Drug Administration, see the Reference Guide on the CD-ROM.

Ozone gas is generated by laser printers as a by-product of the printing process. 
Ozone is produced only when the printer is printing.

The recommended exposure limit for ozone is 0.1 parts per million (ppm) expressed 
as an average time-weighted concentration over an eight (8) hour period.
The EPSON EPL-5900/EPL-6100 laser printer generates less than 0.1 ppm for eight 
(8) hours of continuous printing.

To minimize the risk of exposure to ozone, you should avoid the following 
conditions: 

❏ Use of multiple laser printers in a confined area

❏ Operation in conditions of extremely low humidity

❏ Poor room ventilation

❏ Long, continuous printing together with any of the above

The printer should be located so that the exhaust gases and heat generated are:

❏ Not blown directly into the user’s face

❏ Vented directly out of the building whenever possible

❏ Allow adequate space for easy operation and maintenance.

❏ Place the printer where you can easily unplug the power cord.

❏ Keep the entire computer and printer system away from potential sources of 

interference, such as loudspeakers or the base units of cordless telephones.
