Uneven Gloss Area Appears At End Of Output Images: Silicon Oil Is Depleted - Canon imagePRESS C7000VP Series Trouble Shooting Information

3.2 Uneven gloss area appears at end of output images: Silicon oil is
depleted
 Description
There are some reported instances from the field where, uneven gloss area [1] appeared at an
end of output images because silicon oil applied to the fixing belt has been depleted. When the
same symptom occurs, perform the following procedure.
 Field Remedy
1. In order to identify the cause of the symptom, instill 0.1ml of SILICON OIL S400 into the
corresponding end of the fixing belt assembly with a dropper.
2. Output a few halftone images and check to see if the symptom was improved.
3. If the symptom was not improved, repeat Step 1 and 2 to increase the amount of SILICON
OIL up to 0.6 ml in increments of 0.1 ml.
4. If the symptom was improved, suspect depletion of SILICON OIL and go to Step 5. If the
symptom was not improved, replace the fixing belt with a new one.
5. Detach the fixing belt from the fixing belt assembly found in the first fixing assembly, and
then wipe SILICON OIL S400 off the oil roller, inlet roller, pad cover, and inner surface of
fixing belt with lint-free paper moistened with alcohol.
6. Place one sheet of A4-size paper in the landscape orientation, and cut it about one-eighth
in width; then fold the cut piece of paper in three. After that, draw in 0.8ml of SILICON OIL
S400 with a dropper.
1. Drop the measured SILICON OIL S400 on the area [B] of the pad cover, and then
spread it over with the folded piece of paper. At this time, be sure not to apply the oil to
the emboss areas [A] (i.e., 30mm away from respective ends of the cover). 8. Rub the
folded piece of paper against the emboss areas [A] so as to transfer the remaining oil
there and form a barely seen layer of oil.
2. Rub the folded piece of paper against the emboss areas [A] so as to transfer the
remaining oil there and form a barely seen layer of oil.
