Maintenance Procedure

Cover (Exterior) Cleaning

CAUTION: Do not allow liquids to get inside the product. Otherwise, there is a risk of failure, electric shock, or fire.

For heavy soiling, wipe using a soft cloth soaked in dilute detergent and thoroughly wrung out.

Cleaning the Y-Bar Rail Surfaces

Important! Before use, gently wipe the four rail faces (A to D) with a dry cloth to remove any dirt or dust. Dirt on the rails can cause abnormal noise and affect cutting quality.

Rail Surfaces:

• A: Upper rail rear
• B: Upper rail side
• C: Lower rail side
• D: Lower rail rear

Cleaning the Grit Rollers

Over time, the grit rollers may become clogged with paper dust, causing sheets to slip. Visually check for debris and clean promptly. A brush (like a toothbrush) is recommended for cleaning. Use a small amount of alcohol if dirt is difficult to remove.

Cleaning the Pinch Rollers

Leaving debris on the pinch rollers can cause buildup and hardening. Wipe them clean with a dry cloth or a cloth moistened with alcohol.

When Not in Use for Extended Periods

If the product will not be used for one week or longer:

• Do not leave sheets loaded on the platen, as this can create irregularities or ripples in the sheet.
• Push the clamp lever to the rear to separate the pinch rollers from the grit rollers. Leaving the pinch rollers in the lowered position for extended periods may cause deformation, affecting sheet feeding.
