Officejet Pro 8500A A910a receives print job but does not print

[KimYT]

After 2 months of working fine, the HP 8500A 910 now frequently receives a print job or fax but just shows a message on the printer's display, "now printing" ... but never prints.  If I shut the printer down and restart it, I can get 1-2 print jobs through before it reocurs.

This is a networked printer on a cable net with 2 desktops.  No PC is direct-connected to it.  This is a business and we very badly need this to be fixed.  Can someone communicate with me on this?

I have exactly the same problem.   After restarting, the HP Officejet Pro 8500A A910 prints fine, but after 30 minutes or so, new print jobs are sent to the printer, it displays "now printing", and ... nothing.

Product model # CM755A.  I printed the self-test diagnostic page, then checked the website, and the installed firmware is the latest available version:  LRP1FN1126AR

The self-diagnostic page shows that a recently replaced yellow ink cartridge (refill from Cartridge World) was not recognized.  

When printing from an iPhone 4 via AirPrint, I get a message on the iPhone that the printer is out of ink, but the printer display just shows "Now printing..." and a red X next to the display.  In this state when printing from a Windows PC, I get a message "user intervention required" but an "out of ink" message never appears on the printer's display.  

I think another firmware update is required to put a proper "ink error" message on the printer's display...

yes, solution above was correct for me too.

my new 8500a run out of genuine black . i refilled it.

turned off the cartrige out of ink warning, worked fine for 3 months.

yesterday the "now printing" status  occoured, and only prints for a few minutes after reboot.

i had a spare genuine cartrige,so  installed it, and all is perfect again.

there is a page count on these chips, and to dodge legal issues HP dont put an error on the screen, and if u call up they wont support refills.

quite smart but that annoys me because i never would have bought it if i knew this

perhaps a firmware rollback may fix???

hopefully someone works this out.

what they have done is illegal,and  i hope someone sues them to teach a lesson.

cheers.

I have an 8500A A910g purchased from Costco 5 months ago.  It worked flawlessly until I replaced the yellow cartridge with a 3rd party cartridge a week ago.  I received a message on the printer screen "Counterfeit or Used Cartridge Detected" and a warning that if I proceeded, the warranty would be voided.  I proceeded.

From that point on, I had the same problem as described by the other contributors to this forum - "now printing" displayed on the printer, but no output.  On the dialog box with the status of the queue for the printer, the header suffix changed from "low ink or toner" to "user intervention required".  I recycled the power on the printer to clear the job and started the job again for the first print of each day and often throughout the day.

With the help of a response on another forum, I discovered that opening and closing the print cartridge access door cleared the "user intervention required" state and then printing would proceed without the need for cycling the power.  I guess one intervention fits all when it's just a ruse to punish users of refilled ink cartridges.  I hope this workaround helps other victims of the refilled-cartridge retribution before HP finds a way to disable the workaround.  I would hope they would fix what we consider to be a problem, but I don't think they agree with us.

What we need to do is figure out how to rollback the firmware to an earlier version w/o the cartridge detection....

Modifying the firmware so that the printer "breaks" itself when anything but "genuine HP ink" is used is sneaky, and probably illegal. I now have to open and close the ink door every time I want to print or copy something.

Personally, I will never buy another HP printer again. I recommend that others do the same. Find yourself a reputable company that doesn't resort to dirty tricks.

Using the non-HP print cartridges worked fine for a few months, then I had to restart the printer every time in order to print.  Replacing them with HP print cartridges did the trick for me as well.  Though I'm happy the printer is working again, I also find it infuriating that HP has "tricked" their customers into buying only their ink cartridges.  There are plenty of other manufacturers and this will be the last HP product that I buy.
