AR-M550/M620/M700  DETAILS OF EACH SECTION  6 - 109

1) Remove the fusing unit. (See “a. Fusing unit” in this section)

2) Release the pressure. (See “a-4. Heater lamp 1” in this section)

4) Remove the fusing roller (pressing) unit.

5) Remove the bearing from the fusing roller (pressing).

• Wind paper with the scraper tip without scratching the pressure

roller, and insert it.

• When inserting, be careful not to deform the scraper.

• Engage the bearings F/R with the pressure lever concaves and pull

out the paper from the scraper side.

• When closing the unit, first close the upper unit from the above in

order to prevent against deform of the scraper.

1) Remove the fusing unit. (See “a. Fusing unit” in this section)

2) Open the fusing unit.

3) Remove the pressure roller unit.

4) Remove the fusing cleaning scraper.

3) Remove the screw to open the fusing unit.

• When replacing the pressure roller or the scraper, they must be

replaced together. (This note should be observed within the mainte-
nance cycle.)

• When assembling the used pressure roller to the original position,

set it in the original direction (F-R direction). If it is set in the reverse
direction, it may not fit with the scraper, resulting in insufficient clean-
ing. If, however, the pressure roller and the scraper are replaced
together with new one, there is no need to consider this note.

NOTE: Avoid rattling of the pressure roller and the scraper. If not, the

scraper may be deformed and the pressure roller may be
damaged.

• When installing the pressure roller to the fusing unit, be careful not to

damage the cleaning blade.
If the cleaning plate would be deformed, copy dirt would be resulted.
