Section 3: Maintenance and Shutdowns
Following are the recommended maintenance procedures to keep the IJ4000 Impulse Jet system printing cleanly and efficiently.
System Maintenance
Intermittent (as required):
1. Be sure the photosensor is clean and free of debris.
2. Be sure the O-rings on the encoder wheel are present and not worn.
3. Be sure the nuts and bolts holding the bracketry in place remain tight.
Annually:
Replace encoder O-rings (5765-206).
Recalibrate Touch Screen.
Print Head Maintenance
Daily / Shift Startup / Periodic
Wear safety goggles when working with industrial inks or solutions!
The majority of print quality degradation is due to excessive debris deposits on the print head orifice plate that disrupt the ink droplet
path. For best preventative maintenance practices, do the following:
1. Remove excessive debris build-up (corrugate dust, glue strands, and the like) on and around the front of the print head by using maintenance
spray n-Propanol (5760-695) on a clean lint-free cloth (6600-171) and wiping the front plate and enclosure. If debris build-up is noted on the
enclosure and rear of the print head, then wipe those clean, too.
NOTE: DO NOT SPRAY n-Propanol DIRECTLY ON THE PRINT HEAD OR ANYWHERE NEAR THE ORIFICE PLATE
