Try changing to a heavier paper type, such as HP Heavyweight Coated Paper or HP Super Heavyweight Plus Matte Paper. 4. Select a paper type that is slightly thinner than the paper you have loaded; this will persuade the printer to use less ink. Here are some example paper types in ascending order of - HP Designjet T2300 | HP Designjet T2300 eMFP Printer series - Image Quality Trou - Page 12

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 - HP Designjet T2300 | HP Designjet T2300 eMFP Printer series - Image Quality Trou - Page 26
, use Best quality. We also recommend using coated or glossy paper in order to avoid grain in copies. ● If the problem appears in a scanned file, scan at a lower resolution (Standard quality). 4. If the problem persists, clean and calibrate the scanner as indicated in Scanner maintenance on page - HP Designjet T2300 | HP Designjet T2300 eMFP Printer series - Image Quality Trou - Page 27
, call HP support and report "small color differences between adjacent CIS modules". Otherwise, if you see color differences for vivid colors but not for neutral colors, see Clipping in dark or light areas on page 26.
