HP Color LaserJet CM2320 Multifunction Series Printer - Replace the Separation Pad and Rollers

  caution:

Avoid touching the pad surface unless you are going to replace the pad. Skin oils on the pad can cause paper pickup problems.

1. Remove Tray 2 (if installed).
2. Lower the Tray 1 paper pickup assembly by pushing down on the edges of the assembly.
   
3. Release the retainer tabs, and then remove the separation pad from the base.

   note:

   The separation pad base can easily be dislodged when the pad is removed. If the base is dislodged, do not loose the spring under the base (it is not captive).

   

  caution:

Avoid touching the spongy roller surface unless you are going to replace the roller. Skin oils on the roller can cause paper pickup problems.

1. Turn the product on, and wait for it to reach the Ready state. Perform the following steps to rotate the roller to the service position.

   note:

   If you have removed Tray 2 to service the product, reinstall the tray before turning the power on.

   note:

   The following steps rotate the engine paper-pickup roller and the Tray 1 paper-pickup roller into the service position.

   1. Open the 2ndry Service menu by pressing the Left Arrow button and the Cancel button simultaneously.
   2. Use the arrow buttons to select Pick roller, and then press OK.
      Press OK again to confirm that you want the roller to rotate.
   3. Listen for the roller to rotate. When the roller is done rotating, unplug the power cord and then place the power switch in the off position.

        caution:

      It is important to place the power switch in the off position after unplugging the power cord so that the product power does not come on immediately when the power cord is plugged in again.

   4. Remove Tray 2.
   5. Perform the remaining steps in this procedure to remove the roller. After replacing the roller, plug the power cord into the product, and then use the power switch to turn the power on.
2. Carefully raise the front of the product.

     warning:

   Do not place the product face-up resting on the rear cover and rear door. Excess toner might enter the laser/scanner assembly and contaminate the mirrors, causing print-quality problems. The laser/scanner is not a FRU. If the laser/scanner mirrors are contaminated, the entire product must be replaced.

     caution:

   The ADF and scanner cover are not captive and can open suddenly when the product is placed front-side face up. Always support the ADF and scanner cover before placing the product front-side face up.

   Do not lift the product grasping the front door and Tray 2 cavity.

   
3. Use a pair of snap-ring pliers to release two locking tabs and remove the pickup roller.

     caution:

   Do not touch the spongy roller surface unless you are going to replace the roller. Skin oils on the roller can cause paper pickup problems.

   note:

   If you do not have a pair of snap-ring pliers, use your fingers to release the tabs.
