Maintaining and Transporting the Printer|101
Preparing the Printer for Shipment
1. Press the Ppower button to turn off the printer.
Wait until the lights on the control panel stop flashing and go out, and 
then unplug the printer. 
2. Remove the following parts:
Power cord and interface cables
Film and paper baskets
All paper or other media
Optional SpectroProofer (if installed)
3. Leave the ink cartridges installed. 
4. Open the front cover and reinstall the packing material that you 
removed from the print head during setup. Then close the cover.
5. Before you remove the printer from the stand, 
make sure the casters are locked.
Caution: Always turn off 
the printer by pressing 
the Ppower button. 
During shutdown, the 
printer caps the print 
head and flushes it with 
cleaning liquid. This takes 
several minutes to 
complete. To prevent 
damage, never unplug 
the printer during this 
process.
Ti p :  For more secure 
transportation, tape all 
doors and covers shut.

6. Remove the two wing nuts and lock washers securing the printer to the 
stand (underneath the printer). Keep them in a safe place.
7. Lift the printer using the handgrips, two in front and two in back.
8. Keep the printer level while moving it. See page 103 for information 
about setting up the printer after transporting it.
To ship the printer a longer distance, you should repack it using the original 
box and packing materials. If you don’t have the original packaging, you can 
purchase replacement packaging from Epson. See page 10 for more 
information.
Moving the Printer on the Stand
When you need to move the printer a short distance, such as within the same 
building, you can roll the printer on its casters. 
1. Press the Ppower button to turn off the printer.
Wait until the lights on the control panel stop flashing and go out, and 
then unplug the printer. 
2. Disconnect the power cord and interface cable.
3. Remove any paper and close the roll paper cover. Make sure the front 
cover is closed.
4. Remove the film basket as described on page 64.
5. Store the paper basket as described on page 72.
WARNING: The printer is 
very heavy. Make sure you 
have four people lift it.
Caution: Do not roll the 
printer on angled or 
uneven surfaces.

6. Unlock the front casters.
7. Carefully roll the printer to its new location, then lock the casters. 
Setting Up the Printer After Transportation
Setting up the printer after transporting it is almost identical to setting it up 
for the first time. 
Keep in mind that if you haven’t used the printer for more than a week, 
you’ll need to turn it on and shake the white ink cartridge (see page 79). You 
may need to run a cleaning cycle (page 83) and realign the print head 
(page 87) to ensure good print quality.
Storing the Printer
If you don’t use the printer for a long time, the print head nozzles may 
become clogged. Ideally, you should print on a regular basis to prevent 
clogging.
If you need to store your printer for an extended time, take the following 
precautions:
Before storing the printer, press the Ppower button to turn it off, and 
wait until the lights on the control panel stop flashing and go out. This 
ensures that the print head is properly capped and flushed with cleaning 
fluid.
Leave all ink cartridges in their slots during storage. Otherwise, the ink 
may dry out and clog the supply lines.
At least once a month, turn on the printer to remove and shake the 
white ink cartridge (see page 79). If the 
AUTO NOZZLE CHECK setting 
is turned on (this is the default setting; see page 86), the printer will 
automatically check and clean the print head at this time, if necessary.

104|Maintaining and Transporting the Printer

Cover the printer with a non-static cloth. This helps protect it from 
dust, which can interfere with the print head nozzles.
Before returning the printer to use, follow these steps:
1. Turn on the printer and shake the white ink cartridge (see page 79).
2. Run a nozzle check and select the 
PRINT WITH WHITE INK option 
(see page 83).
Check the results and clean the print head, if necessary (see page 84).
3. If the printer hasn’t been used for more than a year, you may need to 
refresh the white ink supply (see page 86).
4. You may also need to realign the print head (page 87) to ensure good 
print quality.
