Clean And Inspect Stepper Motor Gears; Clean And Inspect Mpcb - ENCAD CADJET Service Manual

Cleaning the flex cable contact area is very important due to the ease
of which this area can become dirty. The flex for the yellow cartridge
is deceiving because it is not readily apparent that it is dirty. This
also causes the cartridges to not receive all of the electrical signals for
a proper firing of the jets. This can be seen as a misfiring of the
cartridge.
Care should be used when handling the flex cable con-
tact area. Avoid touching the contact area because the
oils on your skin can contaminate the area and result
in misfiring of the inkjets.
Clean the flex cable contacts by gently dabbing the area with a cotton
swab soaked with isopropyl alcohol.

Clean and Inspect Stepper Motor Gears

The stepper motor gears can become dirty and after time if not
cleaned up, it could cause wide banding in the print. This will reduce
the quality of the intended output. Clean the motor gears with a stiff
brush to knock off any debris. A cotton swab soaked isopropyl alcohol
can be used to remove any ink that may have accumulated on the
gears.

Clean and Inspect MPCB

Foreign material on the MPCB could short out electrical signals being
developed on the MPCB and cause erroneous prints or even damage to
the MPCB. All electrical circuits should be free of foreign material,
especially those materials with conductive properties.
Clean the MPCB by blowing the objects away or gently brush them
aside with a soft brush if required.
Inspect the MPCB for any damage to the board, connections, or any of
the components on the board. Replace board if inspection reveals any
damage or flaws that could effect the function of the MPCB.
