printer on a Windows 98 computer and it was working fine. Then she bought a new computer with Windows XP and connected the printer to it. When her daughter tried to print something, it started printing and then suddenly stopped, ejected the paper and the print cartridge light started blinking so the printer will not print. Now, I've been looking to see what the problem is and I've noticed that the sockets for the ink should have ESD blades (part # C2145-00037). I've also noticed that the socket for the black ink does not have one. I http://h30434.www3.hp.com/t5/Inkjet-Printing/Installed-ink-in-deskjet-840c-but-ink-light-still-flashing/td-p/2478703 am wondering if this might be the problem, since I've already tried cleaning the ink cartridge contacts, but the light is still blinking. Can anyone please tell me what this blade does? What it is for? I've done searches to find out but haven't found any info at all. If the problem is not the blade, then any suggestions will be helpful. Thank you for your help. Respond to this 1 http://fixyourownprinter.com/posts/26197 Make sure that the encoder strip is connected on both ends. The encoder strip is made of thin plastic about 1/4" wide and runs horizontally the length of the printer. If it has become disconnected it must be rethreaded through a slot in the carriage before being reconnected.If the encoder strip appears to be ok, clean it on both sides using water. Use caution or you will disconnect it from one of its mounting hooks. by Bert on Dec 12, 2007 at 3:28pm Add comment Please sign in to comment 0 We get lots of questions about 'missing' ESD blades. Many HP printers only have one on the color cartridge side. After disassembling a carriage, I cannot imagine how one could fall out, i.e. if one is 'missing', HP did not originally install it. ESD means electro static discharge, so it is used to drain static electricity from the cartridge. by Bert on Dec 30, 2004 at 10:03pm Add comment Please sign in to comment 0 You may be right Bert, but stranger things have happened. I'm just making sure this is not one of them. So then, how come does the printer cartridge light keep blinking and the printer won't print? This printer was printing before it suddenly stopped and
James Sweet, May 15, 2007. James Sweet Guest My Deskjet 840C printer has been great, until now I've never had a problem with it. Black ink ran out, started fading then only a few streaks of black. I http://www.electronicspoint.com/threads/deskjet-840c-replaced-black-cartridge-now-the-orange-led-is-blinking-and-wont-print.95568/ popped in a new cartridge and now it just sits there blinking the orange (bottom) LED and makes a soft clunk every 10 seconds or so. I've tried power cycles, unplugging it, putting the old cartridge in, https://www.manualslib.com/manual/273917/Hp-Deskjet-840c.html etc. Anyone seen this before? I know it's cheap to just go buy a new printer but it bugs me to just toss it out when it's been working fine and I have a few spare cartridges. hp deskjet James Sweet, May 15, 2007 #1 Advertisements b Guest On 15 mayo, 22:35, "James Sweet" <> wrote: > My Deskjet 840C printer has been great, until now I've never had a problem > with it.
