Remarks

If the machine is not used for a long period, the image density might decrease because the ink on the drum might dry. Make extra prints until the image density recovers.

When the machine is used in low temperature conditions, the image density might decrease. In this case, slow the printing speed down to step 1 or 2.

When making duplex prints, misdetection of paper wrapping might occur if the paper delivery sensor detects a black area at the leading edge of the back side. Keep at least an 5mm, 0.2" margin at the leading edge of the back side of the printing paper.

Press the {Proof} key to perform a test print as the first few prints might be light.

The top sheet might remain between the feed rollers when you press the {Paste Shadow Erase} key. In this case, remove the top sheet.

When making duplex prints or when using non-white printing paper, the pa- per end sensor might malfunction and fail to detect the paper. In this case, place a blank sheet under the printing paper on the paper feed tray.

The outer portion of the image might not be printed under low temperature. In this case, slow the printing speed down to step 1 or 2, or increase the room temperature.

6 • The paper exit pawl might contact the printing paper and cause black lines on the prints. In this case, increase the printing speed or make a new master with lighter image density mode.

If you cannot pull out the drum, close the front cover again to rotate the drum. Pull out the drum after it stopped at the position.

The leading edge of the prints might become stained if the edge touches the image of prints on the paper delivery tray.

The ink of the print on the paper delivery tray might stick to the back side of the next print.

When the machine is on and the power source is less than 90 % of the speci- fied amount, printing quality will decrease. Therefore, make sure the supply from your electrical outlet is at least 90 % of the required amount.

As various kinds and qualities of paper exist, some paper might be wrapped around the drum or cause misfeeds.

If your hands are stained with ink:

Avoid prolonged or repeated contact with skin.

Cleanse skin thoroughly after contact, before breaks and meals, and at the end of the work period.

Ink is readily removed from skin by waterless hand cleaners followed by washing with soap and water.

Also, be careful not to get any ink on your clothing while emptying the master eject box or while loading a new ink cartridge.
