printer.

The environmental requirements for correct operation of the printer are as follows.
If the ventilation duct at the top of the printer becomes blocked, the inside of the printer will accumulate heat, resulting in a malfunction or fire. Do not place any objects over the ventilation duct.
CAUTION The area around the fusing unit is extremely hot. Be careful not to touch any parts around the fusing unit, other than those indicated in this manual, in order to reduce the risk of burns. Be especially careful not to touch parts marked with warning labels, and their surrounding areas.
If you get burnt, immediately cool the skin under cold water, and then seek professional medical advice.
Transporting the printer If you need to transport the printer over a long distance, consult your technical representative. Care of printer supplies Use the following precautions when handling the printer supplies (toner cartridge, paper, etc.).
Store the supplies in a location that meets the following requirements.
Free from direct sunlight Away from any heating apparatus Not subjected to high humidity Not extremely dusty
Store in a sealed plastic bag in a cool, dark place paper that has been removed
from its wrapper but not loaded into the printer.
Only use toner that has been manufactured specifically for this printer. Never use other types of toner. Keep all supplies out of the reach of children.
If your hands become soiled with toner, immediately wash them with soap and water. If toner gets in your eyes, immediately flush them with water, and then seek professional medical advice.

Storage of prints

Prints that are to be kept for a long time should be kept where they are not
exposed to light in order to prevent them from fading.
Adhesive that contains solvent (e.g., spray glue) may dissolve the toner on prints. Color prints have a thicker layer of toner than normal black-and-white prints. Therefore, when a color print is folded, the toner at the fold may peel off.

Note If the paper is curled, flatten it before loading it. Do not load so much paper that the top of the stack is higher than the mark.
Paper other than plain paper cannot be fed from the 2nd drawer or optional paper feed units. If you wish to make prints onto paper other than plain paper, feed it through the manual bypass tray or the 1st drawer. When loading additional paper, remove any paper remaining in the drawer, place it on top of the new paper, and then align the paper in the stack well before loading it into the drawer. If the paper is not aligned well, a paper misfeed may occur. We recommend replenishing the paper only after all of the paper in the drawer has been used.
6 Close the paper drawer.

1 Open the manual bypass tray. 2 Prepare one sheet of the paper.
3 Load the paper into the manual bypass tray
so that the front side of the paper (the side facing up when the package was unwrapped) faces down.
When making manual double-sided prints, load the paper into the manual bypass tray so that the second side (the blank side) faces down. Prints will be made on the surface of the paper facing down when paper is loaded into the manual bypass tray.
4-19 Note Do not load L (A6) cards crosswise, as shown.
Tip Before loading envelopes, press them down to make sure that all air is removed, and make sure that the folds of the flaps are firmly pressed, otherwise the envelopes may become wrinkled or a paper misfeed may occur. Load the envelopes with the shorter side as the leading edge and with the side to be printed on facing up, as shown in the illustration.
Tip When loading Overhead Projector transparencies, load them with the longer side as the leading edge, as shown.
Note Do not load Overhead Projector transparencies lengthwise, as shown.
4 Adjust the paper guides to fit the
size of paper that is loaded.
5 Lightly slide the paper into the feed
slot as much as possible so that the edge of the paper is fed into the printer.
Feed only one sheet of paper at a time.

8. Handling of the PC Drum Only for Products Not Employing an Imaging Cartridge.
During Transportation/Storage Use the specified carton whenever moving or storing the PC Drum. The storage temperature is in the range between 20C and +40C. In summer, avoid leaving the PC Drum in a car for a long time. Handling Ensure that the correct PC Drum is used. Whenever the PC Drum has been removed from the copier, store it in its carton or protect it with a Drum Cloth. The PC Drum exhibits greatest light fatigue after being exposed to strong light over an extended period of time. Never, therefore, expose it to direct sunlight. Use care not to contaminate the surface of the PC Drum with oil-base solvent, fingerprints, and other foreign matter. Do not scratch the surface of the PC Drum. Do not apply chemicals to the surface of the PC Drum. Do not attempt to wipe clean the surface of the PC Drum. If, however, the surface is contaminated with fingerprints, clean it using the following procedure. A. Place the PC Drum into one half of its carton.

1076D001

1076D002
B. Gently wipe the residual toner off the surface of the PC Drum with a dry, Dust-Free Cotton Pad. Turn the PC Drum so that the area of its surface on which the line of toner left by the Cleaning Blade is present is facing straight up. Wipe the surface in one continuous movement from the rear edge of the PC Drum to the front edge and off the surface of the PC Drum. Turn the PC Drum slightly and wipe the newly exposed surface area with a CLEAN face of the Dust-Free Cotton Pad. Repeat this procedure until the entire surface of the PC Drum has been thoroughly cleaned. At this time, always use a CLEAN face of the dry Dust-Free Cotton Pad until no toner is evident on the face of the Pad after wiping.
C. Soak a small amount of either ethyl alcohol or isopropyl alcohol into a clean, unused Dust-Free Cotton Pad which has been folded over into quarters. Now, wipe the surface of the PC Drum in one continuous movement from its rear edge to its front edge and off its surface one to two times. Never move the Pad back and forth.
