Corrective or Preventive Maintenance
Because the GQ-3500’s status messages advise you when to replace
supplies and consumable parts, little additional preventive
maintenance is required. If the printing quality should decline,
however, it may help to clean the transfer charger wire. Do this
whenever you replace
the
drum cartridge, and periodically as required
to maintain maximum printing quality.
Transfer Charger Wire
To clean the transfer charger wire, follow
these steps:
1.
Open
the
printer by releasing the latch on
the
front of the printer.
-
WARNING
Opening
the
printer exposes the fusing unit, which is marked by a
CAUTION: HOT SURFACE
label. Be careful not to touch the fusing unit.
Raise
the
green handles and lift out the drum cartridge (the
collector unit together with the drum).
Locate the small cleaning blade, a user maintenance tool stored
inside of the printer. This cleaning tool is in the boxy receptacle
located at the
front
of the printer to the right of
the
toner
cartridge. (Note that the direction the cleaning blade is stored is
the reverse of the direction you use it.) Remove
the
blade from the
receptacle.
Clean the transfer charger wire with this cleaning blade, as
follows. (The wire is thin and may be difficult to spot instantly;
look closely.) Place the blade at one end of the charger wire
(located on
the right
side of the drum receptacle) and
move the
blade along the wire. Use
the
blade’s shape as a guide. (See
Figure 5-12.)
Note
As you clean the transfer charger wire, be careful not to touch the
developer roller, which is located immediately above and to
the right
of
the
wire.
