Troubleshooting (Cont’d)
Ink Flow Issues
Ink flow for any printer is like the blood flowing through our veins, any restriction is going to
create problems. Keeping your printer well maintained and clean is an important factor to
trouble free printing. Understanding how ink flows through your printers ink delivery system
will help greatly in preventing and diagnosing issues related to ink flow. Always remember to
keep things simple when trying to trouble shoot ink flow. Start with thesimplest reasons and
then work your way from the bottle to the print head.
NEVER take anything apart or try to install new parts without speaking with an OmniPrint Tech
Support Specialist.
In many cases ink flow issues are related to something very simple. For a quick reference the
following is a list of reasons you could be having a problem. Follow this list first. Make sure all
the basic causes have been eliminated before proceeding with a more in depth diagnosis:
1.Nozzle Check
Make sure that Nozzle Check is always printed after you have gone through your start up
routine of 2 Head Cleans and if needed a Prime of the inks. The Nozzle check will show us
how all the individual channels of color are performing. They should all be as close to 100%
as possible. A few missing dash lines are ok. If you are missing more the 10-15 % you should
try a Head Clean followed by a new Nozzle check. If the problem still looks the same you
should prime the ink system followed by 2 Head Cleans and then a Nozzle Check.
2.Basic Systems Check
Whenever you are having a problem with ink flow and your nozzle check is showing poor
performance of a specific cannel or channels check the following areas to make sure some-
thing simple is causing the problem. This is the most common reason and no matter how well
you know the machine we have all missed done at least one of the following:
�
Ink Clips
Make sure you have un-clipped all the clips at the Print Head. If you
have one full channel of ink missing in your Nozzle Check this is a good reason
why and the most common mistake. Also make sure that the clip on the Waste
Ink Bottle is in the clipped position.
�
Ink Level
Take a look at all the ink bottles on the rear of the printer, especially
the color you are having issues with. If the ink is low you will need to refill it.
Take a look in the bottle, the tube the ink goes through does not go all the way
to the bottom and may be pulling in air or close to doing so. Never let your inks
go all the way down and always refill them when you see about 1⁄4 of the bottle
full. Some people do so at 1⁄2 and this is a very good preventative.
