The elements that most often need repair in a printer are the wiper, dampers, heads, refreshing pad, and the capping (docking) station.

AIS offers discount replacement parts for Epson and Mimaki, as well as some parts for Roland and Mutoh.

You can prolong the life of these parts by cleaning out the printer with our CLF008 cleaning cartridges once a year and placing 3 eye drops of CLF007 on the capping station every night. If every night isn’t an option, apply as many times as you can. Even once a week will significantly help.


Years of repairing inkjet printers has made us aware of the parts that need the most attention and replacement. Dampers should be replaced or cleaned once a year. The damper has a fine, stainless steel screen that filters out small particles. While each ink manufacturer filters their ink well, the formation of these particles have been found in dye, pigment, dye sub, acid, and reactive inks from OEM manufacturers as well as third-party. The damper is clear on one side where you can see the filter screen. The damper sits directly on the head. There is a damper for each color ink, and they are relatively inexpensive.

Dampers sit directly on the heads and protect the head from foreign particles. The damper also traps air that might get into the head. If a damper fails, air may get into the head, causing dropouts. A damper that is filled with particles will not allow ink to flow. With a little practice, removing and replacing dampers becomes pretty easy.

Capping Station

This is the structure that the head sits on. It contains a pad that is used between the head and the pump. The pump sucks liquid through the pad to the head, therefore the pad is constantly saturated with ink. It is one continues pad for all the nozzles. Over time, the pad will become gummed, and the only way to keep it moist and open will be to place drops of CLF007 cleaning fluid on it during a resting period overnight.

After two or three years without cleaning, the pad tends to prevent proper suction. This will result in multiple cleanings to get the heads to fire. One cleaning will clean one set of heads while dropping out the other.


The wiper cleans the head every time a cleaning is performed. It has a life expectancy of about a year and a half. It is also very inexpensive.
