Monthly Maintenance
You will need to lubricate the Bed Rails and Rail Guides on a Monthly basis to facilitate the Print
Assembly moving smoothly during image output. This procedure will help prevent banding as well as
several other image quality concerns.
1. Clean the Print Carriage Drive Belt Gear and Roller
During normal operating conditions, lint that
is coated with Pretreatment can get caught in
the Print Carriage Drive Belt Gear, located
in the right rear of the housing. This lint can
clog causing the belt to slip, resulting in the
Print Carriage jerking around and/or not
complete print jobs. We recommend checking
this gear at least once a month and cleaning if
necessary.
Release Belt
•
To clean, rst release the print carriage using the blue release lever and move it to the left so it is
out of the way. Next remove the drive belt from the gear side of the printer (right side). Be careful
not to damage the belt in any way during cleaning. The belt is equipped with an auto tension spring
and can be removed fairly easily by carefully pulling on the belt (do not twist) until you can pull it
off of the gear assembly.
• Clean Gear
Clean the gear using a wire brush or computer
vacuum. By moving the print carriage from left to right, you
will be able to clean the entire diameter of the gear. For heavy
buildup, use a pick of some kind to pry away any debris that
may be stuck in the gears.
Located at the opposite end of the Printer Assembly is the Drive Belt Roller. Occasionally this component
will require cleaning as well. The belt cannot be easily removed from the roller.
Clean Roller
•
Using an old toothbrush or something equivalent, carefully clean the roller from the inside where
the belt is not touching. DO not use a utensil that may damage the roller. Move the print carriage to
expose the rest of the roller.
NOTE: While performing maintenance on any internal printer part, make sure to avoid ANY
contact with the Encoder Strip. It is fragile and can easily be damaged!
2. Lubricate the Bed Rail Guides
Use a Grease Gun to inject a Lithium-based soap grease
(White Grease) through the four Zerk ttings. DO NOT
over-lube. Using only one “squirt” per Guide is necessary.
Lubricating the two Main Rails will prevent oxidation (rust)
and debris build-up, allowing the Printer Assembly to travel
freely. This will help prevent registration issues that can occur
in multiple pass prints.
