HP Designjet T2300 eMFP Printer series - Image Quality Troubleshooting Guide: English

damaged before calibrating the scanner (an old or damaged maintenance sheet may cause this

problem); if it is damaged, call HP support and ask for a new maintenance sheet.

4. If the problem persists, proceed to analyze the following areas of the diagnostic plot:

a. 4 (from module A to E).

b. 10, at the intersection between modules.

c. 13 in modules A and E, and 14 in modules B, C, and D.

If you see any of these defects in the studied areas, call HP support and report a “line

discontinuities” error after calibration.

The four vertical thin black lines at the beginning and the end of the diagnostic plot show,

approximately, the position of the intersection between CIS modules, where this kind of error usually

appears. If the error appears outside these areas, call HP support and report “line discontinuities within

a CIS module”.

Grain in area fills when scanning plain paper

When making copies of an original containing area fills, if the paper used in the printer is plain paper

(for instance, HP Universal Bond or HP Bright White Inkjet Bond), some grain may appear in the image.

This error may also appear in scanned files of originals that were printed on textured paper. The

example below shows the original image on the left and the scanned, grainy image on the right.

Actions

1. Please look at the original and check if it is dirty, has fingerprints on it or if the grain is already

present in the print. If not, then proceed to step 2.

2. Repeat the scan/copy, setting the content type to Image.
