Important Safety Instructions
Before using your printer, read the following safety instructions to make sure 
you use the equipment safely and effectively.
The Epson Stylus Pro WT7900 weighs approximately 220 lb (100 kg). 
When lifting it onto the stand, make sure you have four people holding 
the printer (see page 21).
When setting up the printer, make sure you have enough space around 
it (see page 17). Leave enough space in front so you can attach the film 
basket.
Place the printer on a flat, stable floor. The printer will not operate 
properly if it is tilted or at an angle.
Avoid places subject to rapid changes in temperature and humidity. Also 
keep the printer away from direct sunlight, strong light, or heat sources.
Avoid places subject to shocks and vibrations.
Keep the printer away from dusty areas.
Keep your entire computer system away from potential sources of 
electromagnetic interference, such as loudspeakers or the base units of 
cordless telephones.
Place the printer near a wall outlet where the plug can be easily 
unplugged.
Use only the type of power source indicated on the label.
Connect the printer to a properly grounded outlet. Avoid using an 
outlet on the same circuit as a photocopier or air control system that 
regularly switches on and off.
Avoid using electrical outlets controlled by wall switches or timers.
Use only the power cord that comes with the printer. Use of another 
cord may result in fire or electric shock.
The printer’s power cord is designed for use with the printer only. Using 
it with other equipment may result in fire or electric shock.
Do not use a damaged or frayed power cord.

Introduction|13

If you use an extension cord with the printer, make sure the total ampere 
rating of devices plugged into the extension cord does not exceed the 
cord’s ampere rating. Also, make sure the total ampere rating of all 
devices plugged into the wall outlet does not exceed the wall outlet’s 
ampere rating.
Do not block or cover the openings in the printer’s case.
Do not put your hand inside the printer during printing.
Do not move the print head by hand unless instructed to do so by an 
Epson service technician; otherwise you may damage the printer.
Do not insert objects through the slots. Take care not to spill liquid on 
the printer.
Do not attempt to service the printer yourself.
Power down the printer from the control panel, unplug the printer, and 
refer servicing to qualified service personnel under the following 
conditions: 
The power cord or plug is damaged; liquid has entered the printer; the 
printer has been dropped or the cabinet damaged; the printer does not 
operate normally or exhibits a distinct change in performance.
Before transporting the printer, make sure the print head is in the far 
right (home) position.
For California customers only:
The lithium batteries in this product contain
Perchlorate Material - special handling may apply,
See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Caution: Always turn 
the printer off using the 
Ppower
 button. When 
you press this button, 
POWER OFF appears on 
the LCD panel and the 
Ppower light flashes. 
Do not unplug the printer 
or turn off the power to 
the printer until the  panel 
shuts off and the 
Ppower light stops 
flashing. This ensures 
that the print head is 
safely capped.

Ink Cartridge Safety Instructions
Keep ink cartridges out of the reach of children and do not drink the 
ink.
Store ink cartridges in a cool, dark place.
If ink gets on your skin, wash it off with soap and water. If ink gets in 
your eyes, flush them immediately with water.
Shake all ink cartridges before installing them for best results (see 
page 88). White ink cartridges must be shaken regularly to maintain 
print quality, even after being installed (see page 78).
Do not use an ink cartridge beyond the date printed on the cartridge 
carton.
Use up the ink cartridge within six months of installation for best 
results.
Do not dismantle ink cartridges or try to refill them. This could damage 
the print head.
After bringing an ink cartridge inside from a cold storage site, allow it to 
warm up at room temperature for at least three hours before using it.
The IC chip on the ink cartridge retains a variety of cartridge 
information, which allows you to remove and reinsert it freely.
If you remove an ink cartridge for later use, protect the ink supply area 
from dirt and dust, and store it in the same environment as this product. 
Note that there is a valve in the ink supply port, making covers or plugs 
unnecessary, but care is needed to prevent ink from staining items that 
the cartridge touches.
Do not touch the ink supply port, its surrounding area, or the green IC 
chip on the top of the ink cartridge. Doing so may affect normal 
operation and printing.
Caution: To prevent ink 
leakage, don’t shake 
cartridges too forcefully.
