For the N2000, the supported media size can be detected by aligning the end guide in the cassette to the media size. As for the media size, which is supported but cannot be detected by the end guide, should be set from the operation panel. Those media sizes need to be set are B5 and postcard in Cassette 1, and B5 in Cassette 2.

2.1 Before Troubleshooting

Before troubleshooting, check the following and see if any of the applicable problems can be fixed.

Problem Confirmation item Countermeasure

Printer does not operate at all.

Paper is not fed. Remove the jammed paper.

Printer does not print.

Vertical lines misalignment occurs. Image is mispositioned.

Is the power cord properly connected? Is the I/F cable properly connected? Isn’t the fuse of the power unit blown? Check the paper type on the cassette. Isn’t the paper jammed? Is the manual lever set properly?

Does the ink remaining amount warning appear? Perform cleaning and check whether ink flows into the tube. Can the test print be performed? Confirm the carriage cable

Has the print head position adjustment performed? Does the carriage move correctly? Confirm the CR encoder

Check that the cables are connected properly.

Confirm the media height on the cassette. Lower the manual lever.
