2.Press Proceed to continue.
The printer raises the rail and lowering the output roller into position for this operation.
3.Using a lint-free cloth moistened with IPA (Isopropyl alcohol), wipe the top of the encoder strip,
cleaning the entire length of strip.
Use common rubbing alcohol, which is 70% isopropyl alcohol and 30% water.
Figure 9-12  Cleaning the encoder strip
4.After cleaning most of the encoder strip, move the carriage to clean the section of the encoder
strip that was behind the carriage. This enables you to clean the entire encoder strip from end to
end.
5.To reset the maintenance counter for this task and complete the procedure, press Proceed.
Clean ionizer needles (quarterly)

							5.Using the brush supplied with the printer (shown n the photo below), clean the ionizer needles (A
in the photo below) located beneath the ionizer bar.
The ionizer bar is located between the input roller and the alignment bar on the input side of the
printer.
The needles (A in the photo below) run the length of the ionizer bar.
6.To reset the maintenance counter for this task and complete the procedure, press Proceed.
The printer repositions the rail and carriage to their home positions.
Clean and lubricate rail strips (bi-weekly)
Ink dust and debris can accumulate on the carriage-wheel strips. These particles become obstacles
and friction for the carriage wheels, which can appear as repeating output anomalies on the printed
media.
NOTE:Users of printers in California must disregard all references to the Printhead Flush or IPA in
the instructions or when displayed on the control panel. Instead, the alternative cleaning liquid
specified at the beginning of this section must be used.
1.From the control panel (System page > Tools > User Cleaning and Maintenance), select
Clean and Lube Rail Strips.
2.Process Proceed to continue.
The printer raises the rail and output roller for easier access to the rail.
3.Using a lint-free cloth and isopropyl alcohol, clean the top carriage-wheel strip from end to end
on the rail (moving the carriage to clean the full length of the rail).

							4.Lubricate the top carriage-wheel strip from end to end on the rail (moving the carriage to clean
the full length of the rail).
The included oiled rags can be reused until there is no clear surface remaining on the rag (rags
should be replaced quarterly). Clean these surfaces weekly or more frequently, depending on
the amount of debris in the environment.
CAUTION:Do not add additional oil to the lubrication cloths. The cloths are created to
distribute a very thin film of oil. If too much oil is deposited, oil pockets can cause friction with the
carriage wheels, which will produce output anomalies.
Figure 9-13  Top carriage-wheel strip
5.Lubricate behind the top area of the rail where the carriage wheels contact.

6.Using a lint-free cloth and Printhead Flush, clean the lower carriage-wheel strip from end to end
on the rail (moving the carriage to clean the full length of the rail).

							7.Lubricate the lower carriage-wheel strip from end to end on the rail (moving the carriage to clean
the full length of the rail).
NOTE:Even if the oiled cloth appears clean, it should be discarded quarterly so that the oil
does not become sticky.

CAUTION:Wear protective gloves, such as latex, to protect your hands from being stained
with ink.
CAUTION:Wear safety glasses to protect your eyes from ink and head flush that may splash
into your eyes.

5.For each printhead, press a clean portion of the cloth with two fingers, each on one printhead,
and draw the cloth across the printhead toward you (see A in the following figure).
NOTE:To avoid pushing debris into the printhead orifice, make sure each wipe is done with a
clean area of the cloth. The cloth should be fully saturated with head flush.
