HP Officejet Pro 8500A Plus stalls displaying "Now Printing".

[sneaksby]

Hi, in the office i work in we have 2 HP Officejet Pro 8500 A910 Series. One is networked to 3 PC's running WIndows 7 and the other is connected via wifi to a  PC also running Windows 7.

The problem is the printer that is networked often stalls displaying "now printing" on the printer screen. The only way to continue printing is to turn the computer off and then on again, wait for it to do its cleaning etc then press print again. This is usually ok for that print job but as soon as further print jobs are added it has to be reset and the whole cycle repeats endlesly throughout the day. Until recently the other printer that is connected via wifi was working fine but now that is also doing exactly the same thing described above.

Recently i searched the forums and have discovered this is a common problem with this type of printer.

I have done partial and full resets of both printers to no avail.

Bothe printers are currently using firmware version: LRP1FN1126AR , which i believe is the latest firmware.

Please can someebody explain how to make these printers work properly? Many thanks

Opening and closing the cartrdge door seems to generate an interrupt that resets the connection and unblocks the pending print job(s).

While not a solution to the underlying defect, this is much faster and esier on you and the printer.

Intermittent Lock Ups/Freezes or Not Responding using "most" OFFICE products.  Very troublesome, especially with Excel...any ideas ?

Thanks for this tip - it did work. Still doesn't explain WHY it keeps doing this - but a quick fix for sure!

This HP model (and possibly others) is sensitive to non-OEM print cartridges being used, and will corrupt the print process automatically by freezing on the "Now Printing" portion of the cycle.

It's their way of forcing you into purchasing new OEM cartridges.  There is no way around it.

ok, i have done the most research into this issue of all people, as i bought 3 of them for buisness.

the most common problem is the printer will only print for 20 or so mins after a reboot, then it goes to sleep,

if attempting print after this time, it will display "now printing" but nothing prints.

after hours to customer support, and a new printer delivered, plug in the expired/refilled genuine cartrige, same issue.

you can wake up the machine tempoarily by opening and closing the cartridge door.



i finally got the lady from HP to admit there is a page count on the chips, and instead of an error on screen,they do this to avoid law suits.she didnt admit to the last bit tho,lol.

i have 3 expired , refilled genuine chips now, all do the same all after around 5000 pages.

cheeky buggers!!

someone with time and money, please sue them , im tired of bieng ripped off.
