Printer Left Un-Used

Symptoms:

• I just came back from holiday and my printer does not work.
• I do not print frequently, and I am having erratic problems with my PermaFlow.

Solution:

While you are away, if the printer is not in use, air can come in backwards through the print head and get into the cartridges. When this happens the ink inside the cartridges can get foamy, and foamy ink causes the nozzles not to fire. Please refer to the Air/Foam within the cartridge section. 
Air can only get in, if the seal surrounding the nozzles is leaking. Cleaning the rubber gasket that is on the outside perimeter of the dump sponge will help prevent air from getting at the nozzles.

Make sure your printer is in a cool place and not exposed to sunlight. This helps keep the inks from retracting or evaporating.

Here is what you should do to prevent this in the future -

It is strongly recommended to plug your printer power supply into a seven day timer which can turn the power of the printer on and off at least once a week while you are away. This will initiate a full head clean cycle before shutting off again and keeps the ink flow moving in the right direction.
If you print fairly regularly, leave your printer switched on all the time. The power used is very low and by not switching it on and off, you save ink and keep nozzles good because it does not carry out unnecessary head cleans – too much head cleaning can make nozzle printouts worse rather than better depending upon the condition of the printer at the time.
Make sure your printer is not exposed to any direct sunlight. The heat from the sun can cause the inks to expand in the tubes and in the print head causing problems. Because we use clear tubing, the sunlight hitting the tubes can accelerate bacterial reactions inside the tubes. So keep your system out of the sun while you are away.
When you get back, print something. If you have missing nozzles, run a few cleaning cycles to recover them. Remember, do cleaning cycles in groups of 3, then print the purge file as recommended.

If repeated cleaning cycles do not bring your printer back to life, then go to the Air/Foam within the cartridge section and follow the procedures outlined.
