I can’t help much. I have lost two R280’s while using re-fillable chipped cartridges. The supplier of the ink and cartridges suggested the printers were the problem. My gut says he’s wrong. I’d like to here from anyone who has had good luck with an EPSON R280 and ANY after market system.
Back to your firing problem. All I can say is you’ll have to install OEM cartridges and see if it don’t come back to life. Check craigslist.org. I’ve gotten several R280’s for $35 to $40. I never pay more than $40. That’s better then $75 or so for ink at the store.
In fact, buy two of them. Take ink from the one and see if yours doesn’t come back to life after three cleanings. If it doesn’t, then use some scotch tape to seal the OEM’s and then put them in a baggie. Install your CIS system in the new printer. When that one quits spitting out black ink go ahead and toss the two defective printers. Take two aspirin and call me in the morning.
