Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
No need to print on all the heads with black. I use one head on my 4900 and it is as dark as using several when I had Accurip. Your just going to have to do a deep power clean. They will come back.Buy refillable bulk ink tanks. Cheapest way to keep that baby running.
Bought a used 4900. Got Accurip (printer has all black cartridges) and did a print. Had some streaks. Did a nossle check and only 4 of the 10 heads work. Did manual cleanings and right now I have 6 heads printing and one is showing life. Any tips or should I just keep doing manual cleans and cross my fingers?Other questions.Do you guys keep it on 24/7?Where do you buy ink at for a good price.?The thing is a beast. I love it even though 4 heads right now don't print.
running all black in your 4900 will shorten your printers life by as much as 7 years. I learned the hard way. I have 3 here and 2 still in the box. Problems only came after about a year of using all black. My Opinion.
if you touch both the little metal tabs on the cartridge with a screwdriver at the same time, it resets. No chip resetter needed. Yes you can use the heads that work, but eventually they will all clog. Google the windex trick for cleaning heads, it will unstop some of the dead ones and prolongs the life of the printer for a while.
pierre, do you mean microcenter?
