Install each printhead in turn taking care to route the hoses through the hose
guide and away from moving parts. Make sure that the hoses are not bent or
pinched as this would impede the flow of ink to the printheads
Once the connection is made between the printhead and the ink reservoir, it cannot be
taken apart without damaging the system. It is best if the system is left in the AstroJet
Image Blaster Printer, but sometimes that is not possible. When handling the system, it
is important to keep the pen as close to the reservoir as possible without letting it go
below the reservoir.
If the printhead is held more than 10 inches above the reservoir, air will be drawn into
the cartridge. Air inside of the pen can not only cause print defects, it can also cause
the pen to stop printing before all of the ink has been used. If the printhead goes below
the reservoir, ink will seep from the printhead, potentially damaging the system. Read
the Caution on the back of the reservoir.
The reservoir and printhead should always be held together when handling the system.
The system should never be held or carried around such that the print head or reservoir
is dangling by the tubing. These actions could cause loss of ink.
