Operation Notes

121

• In Letter/Photo mode, moire patterns might occur when screened originals

are printed. In this case, make prints in Letter or Photo mode.

• When you use originals with light lettering, edges of the letters might be

printed clearly and the inside of the letters might be light. In this case, in-

crease the image density.

• When marks on the printing paper occur, clean the paper feed roller. See

p.124 “Maintaining the Machine”.

• If you make a second print before the ink from the first print dries, the ink

may adhere to the paper feed roller and soil the print. Before printing on the

reverse side of a printed sheet or overprinting on a printed sheet, be sure that

the ink on the first print is adequately dry.

Print Paper

• When the paper is curled, stack the paper with the curl face down, otherwise

the paper might wrap around the drum or stains might appear.

• Postcards and the like do not absorb ink well. Offset images might appear on

the rear side of subsequent prints. Solid image originals will cause offset im-

age prints.

Originals

• If there is no margin or if there is a solid image area near the leading edge of

the original, leave a margin of at least 5 mm, 0.2" at the leading edge; other-

wise, the paper might wrap around the drum or the paper exit pawl might be-

come dirty and cause black lines on prints.

• If you use originals that have bold letters or solid images at the leading edges,

you might get prints with dirty edges. In this case, insert the widest margin

first, or raise the printing speed.

• Under the following conditions, the machine might not detect the original on

the exposure glass. If you press the {Master Making} mode select key again, the

machine will start making a master anyway:

• When you set a dark original on the exposure glass.

• When the original is not centered according to the size marks on the right

scale.

• If you do not open the exposure glass cover at an angle of more than 30°

with the exposure glass when you replace originals.

• If the machine is installed under a strong light.
