Epson pro 7800/9800 and 7880/9880 Initial Fill Procedure:
NOTE: 3-4 Power Clean Cycles can be done thru the printer's control panel, which is equivalent of doing 1 Initial Fill Cycle**
*The printer MUST be started in regular mode to accept "NON-OEM" cartridges FIRST, then turned off and follow the instructions below:
1. Start with the printer power OFF
2. Hold the Down, Right/Menu and Center Cut/Eject buttons while turning the printer on. The printer will start in "Self Testing Mode".
3. Scroll up to CLEANING, and select by pushing the right/Menu button.
4. Scroll and select INIT FILL.
5. When finished, exit Self Testing Mode by turning the printer off, then back on regularly.!

Shaking inks: over time pigment particles can settle, so regular shaking is needed to keep inks in solution. The best time to shake the
bottles and cartridges is when refilling the cartridges. If a printer is not used for a few weeks pigment will settle in the cartridges and ink
lines- to fix this, agitate the cartridges and perform 2-3 power clean cycles. To agitate ink cartridges, remove and gently shake the carts by
tilting forward and swishing around, then reinstall into the printer. Print a nozzle check to confirm all positions are printing, then resume
printing as normal.
•
Use the printer on a regular basis for best function. To keep ink moving thru the ink lines and head moist, print a small image or do a
few cleaning cycles at least once a week. It is not recommended to leave pigment inks installed in a printer that will be unused for an
extended period of time. It’s best to remove ink by installing a set of flush cartridges and running an Initial Fill Cycle to purge ink from the
lines, dampers and print head. This will allow for safe long term storage.!
•
7880/9880 Matte Black mode: Chips on 7880/9880 refill carts are programmed to be universal, so they can be used in any position of your
printer (therefore you need to be EXTRA careful to install cartridges in the right positions). When a printer is in Matte Black mode, it can
sometimes get confused by the refill cartridge chip. Since chips are programmed with both MK and PK info, you will have all (matte and
gloss) media type settings available in the Epson print driver, no mater which cart or ink you’re using (make sure to select the appropriate
settings for the ink you’re using). If you want your printer to remain in MK mode, then you will need to attach an Epson MK chip to the
refill cart, by following the chip replacement instructions on page 9.
•
Storage of cartridges out of the printer: If you want to take cartridges out of the printer for a long period of time, you should store them
upright, with pressure released and fill hole plug securely in place to prevent evaporation and spills. A printer should never be left sitting
for extended periods of time without cartridges installed.
•
Monitor and maintain humidity levels between 40-60% in the printing area. Both low and high humidity can cause problems with printers,
inks and papers.
•
Printer gives “pressurization” error: these printers use pressurized air to “push” the ink out of the cartridges. The printer can sense an air
leak in one or more cartridges and it will not operate if it does so. The printer cannot determine which cartridge is leaking air. If you see a
pressurization error, check the fit of silicone plugs in all the cartridges. Use of O-rings on cartridge air inlet points help create a tight seal
between the printer and cartridges, for proper pressurization and ink flow.
•
Printer gives a “wrong cartridge” or “cartridge error” message: be sure cartridges are installed in the correct positions and securely locked
into position, for tight connection between the cartridge chip and printer’s chip sensor for good read. Make sure there’s nothing on the chip
blocking the read and reinstall the cartridge into the printer. Printer gives “set ink cartg” error: this usually means the printer doesn’t have
tight contact with the cartridge chip, or the chip is shorted out and needs to be replaced.
•
Unable to print a perfect nozzle check pattern after installing new cartridges: occasionally when installing new ink cartridges, the print head
will flood with ink and a perfect nozzle check pattern may be difficult to print. Running additional cleaning cycles can make this problem
appear worse, rather than better. Wait about 30 minutes to allow ink to settle, then print a nozzle check. Don’t do excessive cleaning cycles
if the nozzle check isn’t perfect.
•
Unable to print a perfect nozzle check after use of printer: each time you remove a cartridge from the printer you can introduce a small
bubble of air into the ink tube. This air bubble slowly works its way thru the ink line and may interrupt ink flow when it reaches the
damper. If standard cleaning cycles or cleaning the capping station doesn’t fix the problem, run one or two high powered cleaning cycles to
push the air bubble out of the print head. Before putting a cartridge into the printer, prime the exit channel with ink. If the cartridge is not
primed before installing, air will enter the printer’s ink line before ink starts flowing. You can open the printer’s lid and examine the length
of ink tubes, make sure they are all filled with ink and there are no sections of air inside.!
