Maintenance
To ensure years of precise performance, maintain this product periodically based on frequency of use.
Read the maintenance precautions thoroughly before maintaining this product.
1. Maintenance Precautions
4
1. Maintenance Precautions
• This machine includes parts that must be replaced periodically. We therefore recommend taking
out a maintenance contract. We recommend cleaning this machine and replacing consumable
items to prevent quality defects and accidents.
• Clean periodically. Debris and dust will accumulate on electrical components when this machine
is used for extended periods. There is a risk of failure, electric shock, or fire due to current
leakage.
• Do not clean by blowing—e.g., avoid using air blowers. Doing so may lead to failure, electric
shock, or fire involving the machine if airborne debris or dust gets inside electrical components.
Wipe using a soft cloth soaked in dilute detergent and thoroughly wrung out. A vacuum cleaner
may also be used for cleaning.
• 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.
• Do not use chemical products containing benzine, thinner, or abrasives. Use of these chemicals
may result in damage to or deformation of parts.
• Do not use chlorine-based detergents. Doing so may corrode the machine.

Cover (Exterior) Cleaning
• 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.
3. Maintenance Procedure

Cleaning the Y-Bar Rail Surfaces
• Before use, be sure to gently wipe the four rail faces A to D shown in the following figure with a
dry cloth to remove any dirt or dust. Dirt on the rails may cause abnormal noise and affect
cutting quality.
A: Upper rail rear B: Upper rail side
C: Lower rail side D: Lower rail rear
3. Maintenance Procedure

Cleaning the Grit Rollers
With use, the protrusions on the grit rollers may become clogged with paper dust from sheets, causing
sheets to slip.
To prevent this, visually check for any debris, and clean promptly.
A brush (such as a toothbrush) should be used to clean the grit rollers.
Use a small amount of alcohol if dirt is difficult to remove.
Cleaning the Pinch Rollers
Leaving debris on the pinch rollers may cause it to build up and harden.
To prevent this, wipe clean using a dry cloth or cloth moistened with alcohol.
When Not in Use for Extended Periods
Clean as follows if the product is not used for one week or longer:
• Do not leave with sheets loaded on the platen. This may create irregularities or ripples in the
sheet.
• When this machine is not in use, 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 an extended period of
time may cause the pinch rollers to become deformed. Deformation of the pinch rollers may
prevent the sheet from being fed correctly.
