Troubleshooting & Helpful Information:
Shaking ink bottles and cartridges:
•
actually is; however, periodic shaking is a good idea. The best time to shake the bottles and cartridges is when refilling the cartridges. But if
a printer is not used for a few weeks pigment can 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, (make sure both
fill and air vent holes are plugged to avoid ink spilling) then reinstall into the printer. Be careful to not shake too hard because this will
create froth in the ink and introduce air into the ink lines, just a few tilts back and forth is good. Remove air vent plug to open vent holes
for proper ink flow before using printer, plug vent holes when printer is not in use to prevent evaporation and dust or bugs from getting
inside. 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.
•
a cleaning cycle 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 is best to remove ink by installing a set of flush cartridges to flush ink from the lines, dampers and print head. This will
allow for safe long term storage.
Monitor and maintain humidity levels between 40-60% in the printing area. Both low and high humidity can cause problems with printer,
•
ink or paper.
Storage of cartridges out of the printer: If you want to take cartridges out of the printer for a long period of time, you must store them
•
upright and plug the air vent and fill holes to prevent evaporation and spills.
Watch ink levels in the cartridges: refill a cartridge before ink level gets below 1/2" from the bottom.
•
When to reset: only reset the chip after, or immediately before refilling a cartridge. Do not reset the chip on a less than full cart, as you
•
might run the cartridge dry.
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 tightly 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 (instructions below).
Attach new chip to refill cart: Chips occasionally go bad and need to be replaced. When the printer gives a cartridge error which is not
•
resolved by resetting the chip, this usually means the chip has shorted out and is no longer read correctly by the printer. We recommend
everyone have a set of spare chips on hand to be prepared if a chip needs to be replaced, which is very quick and easy to do. The cartridges
themselves are very robust and will likely last the life of your printer. New chips already read full, so do not need to be reset. Pry the
current chip off the cart using a straight edge screw driver or something similar, then attach the new chip in place of the old one using a
chip-sized piece of double sided tape (DON'T glue chips into place). Make sure gold contacts are facing the front of the cartridge (same
direction as the one you removed). Chips are sensitive to static, so against what you may think, it is best to handle them with clean, dry
hands instead of wearing cotton gloves. With the new chip in place on the cart (with a small piece of double sided tape on the back of the
chip), press straight down with your clean + dry finger or thumb to secure the new chip to the cartridge- making sure it sits flat in the chip
area of the cart and nothing is on the chip contacts that would interfere with the chip read.
Resetter light doesn't come on:
•
unscrewing the two screws (may be under the label). Inside you will find a board with three round batteries attached (batteries are on the
same side of the board as pins that touch the chip contacts). Gently pry up one tab holding each battery down and slide the three batteries
out of place. Wait 30 seconds then slide them securely back into place (it doesn't matter which battery goes into which spot, they're all the
same) and put the resetter back together. Test the resetter on a different cartridge chip (sometimes a faulty chip can short out the resetter, so
testing on a different cart chip rules out the chip). If the batteries are dead, they can be replaced with Energizer 392.
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
or print head. If standard cleaning cycles don't fix the problem and if cleaning the capping station doesn't fix the problem, then 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, tilt it forward to
fill the exit channel with ink. If the cartridge is not tilted forward before installing, this channel can contain air so the air enters 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.
