Print Quality

2The light or dark horizontal lines could also be caused by permanently damaged printheads. The possible combinations with this problem are:

Banding in cyan, blue and green columns only, but more evident in cyan. This means that the cyan printhead could be permanently damaged.

Banding in magenta, red and blue columns only, but more evident in magenta. This means that the magenta printhead could be permanently damaged.

Banding in yellow, red and green columns only, but more evident in yellow. This means that the yellow printhead could be

 

npermanently damaged.

 

Banding in black column only. This means that the black

 

printhead could be permanently damaged.

 

If you want the best high quality image from your printer, replace

 

the damaged printhead with a new one.

 

However, your printer can still produce good quality line prints.

NOTE

 

Banding Caused by Media Advance Problems

 

 

Another type of banding is caused by an inaccurate media advance

 

in this case there will be banding (horizontal repetitive bands along

 

the test pattern) in all the primary and secondary color columns.

 

The bands can appear as dark bands, due to a shorter advance of the

 

roller which causes an overlap, or lighter bands due to a longer

 

advance causing spaces.
