Removing/reinstalling the pick-up roller assembly/separation roller assembly

NOTE

• The pick-up roller assembly/separation roller assembly are CMS corresponding parts.

(1) Procedure

NOTE

• The method for replacing the pick-up roller assembly/separation roller assembly is the same for tray /1 and tray /2. The explanation here is given for tray /1.

• After completion of the installation, rotate the pick-up roller in the direction of the paper feed (counterclockwise as seen from the front) to check to see if the paper feed roller, the belt and the coupling section rotate smoothly. The rotation of the pick-up roller is restricted only to the direc-tion of the paper feed (counterclockwise as seen from the front) and be absolutely sure not to turn it clockwise.

• Be sure to take note that the direction of the pick-up roller is different for the main body and the PF.

1. When the power switch is off, open the toner supply door.

2. Raise up the tray lock lever [1] lightly and pull out the tray [2].

direction (counterclockwise as seen from the front) and place the coupling [2] in the longitudi-nal direction.

NOTE

• The rotation of the pick-up roller [1] is restricted only to the arrow-marked direction (counterclockwise). It does not rotate in the reverse direction (counterclockwise). So, be sure not to turn it in this direction forcibly.

4. Remove 2 C-clips [3].

5. Remove the bearing /Fr [1].

6. Slide the bearing /Rr [2] to the rear side.

NOTE

• When installing the bearing /Fr [1], /Rr [2], insert it in the notch [5] of the metal frame while pressing down a little the metal frame [3] of the pick-up roller assembly to make level the flat portion [4] of the bearing /Rr [2].

And then insert the bearing /Fr [1] in the same manner as with the bearing /Rr.

7. Hold the pick-up roller assembly [1] by hand and lift the paper feed roller [3] up to tilt while rotating it around the shaft [2] of the pick-up roller, and then remove it from the notch [4] of the bearing and the coupling [5].

NOTE

• When removing the pick-up roller [1], be care-ful not to damage the sensor [7] with the metal frame [6].

10. Remove 2 screws [1].

NOTE

• When reinstalling it, fasten it with the screws while pressing down the separation roller assembly [2].

11. After pulling out the front side of the separation roller assembly [1], remove the coupling [2] in the rear from the joint [3].

NOTE

• When reinstalling it, be sure to engage the coupling pin [2] with the joint [3] before instal-lation.

12. Reinstall the above parts following the removal steps in reverse.

NOTE

• After completion of the installation, hold the pick-up roller lightly and rotate it in the direc-tion of the paper feed (counterclockwise as seen from the front) to check to see if the paper feed roller, the belt and the coupling section rotate smoothly. (The rotation of the pick-up roller is restricted only to the direc-tion of the paper feed (counterclockwise as seen from the front) and be absolutely sure not to turn it clockwise.)

(1) Periodically replaced parts/cycle

• Pick-up roller: Every 2,250,000 prints (actual replacement cycle: every 500,000 prints)

• Paper feed roller: Every 2,250,000 prints (actual replacement cycle: every 500,000 prints) (2) Procedure

NOTE

• The outward appearance of the collar is identical for the paper feed roller and the separation roller.

However, a one-way mechanism is provided on the inside of the collar of the paper feed roller with no mechanism provided for the separation roller. Be careful not to confuse one with the other.

1. Remove the pick-up roller assembly.

2. Remove the C-clip [1], remove the coupling bear-ing [2] and then remove the mountbear-ing bracket [3].

3. Pull out the shaft [3] from the collar [1] and remove the pick-up roller [2] from the collar [1].

NOTE

• When reinstalling it, take note of the direction of the pick-up roller. Be sure to insert the col-lar [1] from the side provided with the groove [4].
