The problem

Procolored L1800 printer. It worked perfectly and now prints like this. Do you have any suggestions on how to fix the problem?

Cause and analysis

The image shows a print affected by widespread horizontal streaks and systematic color loss, consistent with dirt or wear on the print head.

A possible print head misalignment or irregular paper feed could cause these variations in density and positioning.

Solution proposed by GPX

A possible cause is the accumulation of dried ink or dust on the print head, which generates streaks and color discontinuities.
