Well, I don't work for the division that makes the inkjet printers, but
I am somewhat familiar with the technology that is used. Essentially the
cartridge has a printhead built directly into it, and the actual print
"head" is analogous to the column of pins in a dot matrix printer. The
difference is that the electronic print head can become dirty, and cause
certain positions in the column to become non-functional. In this case
cleaning the printhead as described in the owner's manual will usually
fix the problem, and eliminate the horizontal lines. If, after cleaning
a cartridge, the horizontal non-printing zones still appear, the
DeskWriter needs a new ink-cartridge/printhead. If the head is new, I'd
take it back to the dealer and get him/her to replace it.
