8 B Smearing on printed side. - Smear on the printed side of paper

- Cannot print properly

- Paper edge crease

1. Correct the paper curl.

2. Recommend the user to conduct

printing in the print quality assurance

area. (In the iP1500, the head-to-paper

distance cannot be changed.)

The edge of paper rises due when paper

is curled, causing the print head to rub

against the printed surface of paper,

resulting in smearing.

9 B Smearing on the backside, or

address side of postcards

when printing the other side

backside of the following paper.

10 C Horizontal lines or uneven print

paper being held, preventing the ink drops

from being ejected in the correct

positions, resulting in unevenness.

Note: The problem is less noticeable than

that of the i320.

Change the print quality from standard to

high mode.

As the print media slightly slips while

being fed by the LF roller, printed areas

overlap, causing the problem.

A: The phenomenon is likely to occur frequently. (Caution required).

B: The phenomenon may occur under certain conditions, but likeliness is assumed very low in practical usage.

C: The phenomenon is unlikely to be recognized by the user, and no practical issues are assumed.
