If you are about to read this, it’s probably because your printer is over two years old and you’re having nozzle drop outs. This is extremely common with printers that haven’t been cleaned on a continual basis. There is information on the web regarding cleaning, with ideas of injecting cleaners into the head, the use of solvents like alcohol, cleaners like Windex, and more. Beware of these approaches, as they may cause more problems than they solve.
The Main Reasons Inkjet Heads Clog
- The printer sat for a long period of time without use
- The capping station is old and gunked with ink
- The printer is sitting in a very dry atmosphere with less than 30% humidity
- Use of a third-party, resin-heavy inks, such as fabric inks, without using cleaning fluid daily
- Use of media with coating that flakes off into the printer and onto the print head
Nozzles That Have Recently Clogged
The first and least expensive approach is to utilize our combination cleaner CLF007P and CLF007P+ as follows:
First, clean the pad of the capping station with a damp paper towel and CLF007P. Wet the capping station with CLF007P and dab it up, repeating several times until the capping pad is relatively clean. Then spray 4 squirts of CLF007P+ on the capping pad and place the head back on the pad. Repeat this every hour. At the end of the day, perform a standard nozzle cleaning or two and then a nozzle check. Keep the print out pattern. If the nozzles are still clogged and it’s the end of the day, place 5 drops of CLF007P on the cap pad, place the head back on the pad, and leave overnight. The next day, if the head is still clogged, repeat the use of CLF007P+, but heat up the bottle and repeat the procedure, spraying the cleaner every hour. If you see improvement, repeat this process for a few days.
If there is not an improvement, but there are more than 30% of the nozzles firing, use our cleaning cartridges to clean out the specific clogged nozzle. For this procedure, you should use CLF008P tinted cleaning fluid and continue placing fluid on the capping station.This approach will bring cleaning fluid into the head. At this point, you will be cleaning from the inside out.
Within a few days you should have a clean head. In order to confirm the nozzles are firing, you can fire the head, performing a nozzle check, and should be able to see just how many nozzles are now firing.
If this procedure fails, which is very unlikely, you will need to take the head out to clean or replace it. To clean it, follow our cleaning procedure. Do not, for any reason, inject fluid into the head as shown on the web by other companies. That is the worst action you can take as it may burst the membrane and destroy the head.
More Than 30% of Nozzles Clogged In Less Than 1 Month
When you have more than 30% of nozzles firing, but you have not been able to clear the clogs with cleaning fluid on the capping station, it is time to use our tinted cleaning cartridges. You can order the entire set or just the ones that you need, but keep in mind that a cleaning cycle pulls all ink from every cartridge.
Place the cartridges in the printer and perform a few power cleans. Let the cleaning fluid sit for at least a few hours before performing a nozzle check. The process of cleaning may take several days or it may only take a day. Be prepared to perform several more regular cleanings before the dried ink is broken loose.
Nozzles Progressively Clogging Over More than 1 Month
If we are not discussing an Epson 7900 or 9900 series printer, then it is possible that there is dried ink in the head that is breaking apart and locking onto the nozzles. This may also be time to use our tinted cleaning cartridges. See the procedure above.
79/9900 Nozzles Clogging in the Center and Slowly Spreading Outward
When you see nozzles clogging in the center of the print and dropping out little by little in a cluster, you have a damaged head. It is not a clog, but the inner destruction of that nozzle group. The only fix is to replace the head.
Magenta Nozzles from a 76/9600/4000 That Are Completely Clogged
Magenta ink is the heaviest pigment and resin load, making it more susceptible to clogging. You should first use CLF007P+ on the capping station every hour.
If the head does not start to open up, you must take the head out and clean it using a 10 ml syringe and polyethylene. Fill a shallow pan filling it up only to the metal rim of the head. Fluid will flow out and you must keep replacing the fluid until the fluid remains clear, then attach the syringe tubing to the nipples of the head one by one and suck no more than 1 ml of cleaner into the syringe with minimum pressure. if there is great resistance stop and keep soaking the head. Try again later. Pull cleaner from one clogged nozzle to the next. Repeat this until you can suck about 3 ml with ease. You will need to replace cleaner into the pan to maintain sufficient level. Once you feel the cleaner is flowing easily, place some distilled water and a little cleaner in the syringe holding the head above you so that you can see the bottom and gently squirt fluid just enough to see it beading up on the nozzles. If it looks like the entire row of nozzles are bubbling replace the head.
