SHARP

REGULAR MAINTENANCE

To ensure that the machine continues to provide top quality performance, periodically clean the machine.

Warning

Do not use a flammable spray to clean the machine. If gas from the spray comes in contact with hot electrical components or the fusing unit inside the machine, fire or electrical shock may result.

Caution

  • Do not use thinner, benzene, or similar volatile cleaning agents to clean the machine. These may degrade or discolour the housing.
  • Use a soft cloth to gently wipe off dirt from the area on the operation panel with a mirror-like finish (shown at right). If you use a stiff cloth or rub hard, the surface may be damaged.

CLEANING THE DOCUMENT GLASS AND AUTOMATIC DOCUMENT FEEDER

Wipe the parts with a clean, soft cloth.
If necessary, moisten the cloth with water or a small amount of neutral detergent. After that, wipe with a clean dry cloth.

Open the automatic document feeder and remove the glass cleaner.

Clean the document scanning area on the document glass with the glass cleaner.

Replace the glass cleaner.

CLEANING THE LASER UNIT

When the laser unit inside the machine becomes dirty, line patterns (coloured lines) may form in the printed image.
Identifying lines (coloured lines) caused by a dirty laser unit

  • Coloured lines always appear in the same place.
  • Coloured lines appear in parallel with the direction of paper feeding.
  • Coloured lines appear not only on output from a copier but also on prints from a computer. (The same lines appear on both copies and print jobs.)
If conditions similar to the above occur, clean the laser unit as explained below.

Open the front cover.

Remove the toner collection container.

Tip the toner collection container forward and down, and slowly pull up.

Take out the cleaning tool for the laser unit.

The cleaning tool is attached to the front cover.
  1. Pull the knob on the right side of the cleaning tool to remove it from the hook.
  2. Place the knob on the back side across the top of the hook.
  3. Turn the cleaning tool around the boss to detach it from the left hand hook.

Make sure that the cleaner at the tip of the cleaning tool is not dirty.

If the cleaner is dirty, remove the cleaner from the cleaning tool and replace it with a clean one. For the procedure for replacing the cleaner, see steps 5 through 7. If the cleaner is not dirty, go to step 8.

Take out a replacement cleaner from the toner collection container.

Replacement cleaners are stored on the toner collection container. Grasp the end of the cleaner and pull it out of the toner collection container.

Remove the dirty cleaner from the tip of the cleaning tool.

  1. Firmly grasp the tool where the cleaner is attached.
  2. Use your other hand to press down on the hook that secures the cleaner, and remove the cleaner.

Caution

Put the removed cleaner back on the toner collection container.

Attach the new cleaner to the cleaning tool.

The cleaning tool is attached to the front cover.
  1. Align the cleaner hook with the attachment hole in the cleaning tool.
  2. Hold the cleaner firmly and push the cleaning tool in.

Clean the laser unit.

  1. Point the cleaner down and slowly insert the tool into the hole that you wish to clean.
  2. Be sure to point the cleaner down.
  3. Insert the cleaning tool all the way into the hole and then pull it back out.
  4. Pull the cleaning tool out until you feel the tip of the tool leave the cleaning surface of the laser unit.
  5. Repeat step 2 two or three times and then remove the cleaning tool.

Caution

Do not touch the internal cords or connectors.

Repeat steps 8 to clean all holes (4 holes) in the laser unit.

The laser unit is cleaned in four locations, including the location cleaned in step 8. Clean all holes.

Replace the cleaning tool.

  1. Engage the cleaning tool onto the boss and turn it around it, and then put the edge (the cleaner side) on the left hand hook.
  2. Put the right hand side of the cleaning tool over the hook to place it on the near side.
  3. Turn the cleaning onto hook.

Push the toner collection container into the machine.

Push in until you hear a "click" sound indicating that the left and right locks are engaged.

Close the front cover.
