First time contributor, please help. Have an HP deskjet 940C; have read paper problems and cartridge problems of others here. Have a similar problem with 'new' cartridge not being accepted-from eink4u.com. Ink level shows ink is there, but the no ink light keeps angrily beeping away. Any help on this would be appreciated. However, it seems many are not happy with this printer. Any suggestions for a dependable and reasonably priced replacement that won't suck me dry on ink cartridges? Thanks!
