Head cleaning
in [Printers]

Essentially because of cost. Head cleaning with most, maybe all, ink printers requires some suction to be applied to the nozzles while ink is being expressed through them. To selectively clean nozzles would require a more complex and therefore more expensive cleaning station. Tony

Because it uses (read:wastes) more ink ... so the user has to buy more ink more often ... and they make their money selling ink, not printers. -- - Nicolaas
From: Arthur Entlich on 15 Dec 2009 10:14 Besides that it would slightly add to the price of the printer due to the mechanics involved, they want to have you use up as much ink as possible, because they make most of their money on the ink sales. Older Epson printers used to have separate black and color inks and cleaning systems. With the precision the heads have in terms of positioning, they could easily have a small cleaning station which only cleaned one area of the head (one set of nozzles). They could even have a wet cleaning system which sued a cleaning fluid to wash the head area down. To do this probably wouldn't add greatly to the costs, but it would lower ink consumption considerably, and that's not what the inkjet manufacturers are wishing to do.

I know my method is not the same as the cleaning cycle, but if I have one color that is not performing, I print blocks of that solid color from MS Word and that usually solves the problem without wasting all the other colors. In fact, the six color test page seems to work real well as a head cleaner. I use that after refilling my Canon and HP 9XX series printers. I think the secret is to buy cheap refill ink and become knowledgeable about filling your carts. Then a little extra wasted on cleaning cycles doesn't hurt so much. |
