gears with a stiff brush to knock off any debris. A cotton swab
soaked with 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 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.
Clean and Inspect Carrier Assembly
Foreign material on the carrier assembly could short out signals
being developed on the carrier assembly and cause erroneous prints
or even damage to the carrier assembly. A very common problem is
where ink has been spilled onto the carrier assembly. All electrical
circuits should be free of foreign material, especially those with
conductive properties.
Clean the carrier assembly by blowing the objects away or gently
brush them aside with a soft brush if required. Be careful not to let
anything to fall into the printer as you clean or it could cause a new
problem later.
Inspect the carrier assembly for any damage to the boards, connec-
tions, or any of the components on the assembly.
