Hey guys, I just thought I would pass along a little maintenance issue we have found in all of our printers. All HP, not sure if its the same with others. open up your printer lid, let the cartridge slide over to the left, now look to the far right where your cartridges "Rest" you will need a flashlight. Do you see a pile of old ink? looks like your cartdige took a dump? We found that this gets tall enough that it gets in the gears, dries up like tar and stops the printer from working. Just take a long screwdriver and scoop that mess out. I call it the black tar disease,I like it because I can say it with a pirates accent in the office Just thought I would pass it along, not sure if its old news or not, but, it cant hurt to inform.
