Can't upgrade firmware Officejet 6500a Plus

[pcwizard]

Hi Talon4x4,

Have you tried updating the firmware with the printer being connected USB?

[Talon4x4]

Yep, tried 4 different ways.  USB, wired, wireless and via the printer update on the printer itself (see post on previous page).

I'm having the same problem with both of my 6500a Plus printers (model # E710n).  Neither will update to firmware version CIP1FN1206AR.  When I run the update, both show status as "Not applicable."  The one with firmware 1110AR will not connect to web services, saying it has no connection even though it is connected wirelessly and printing and scanning wirelessly - thus it cannot be updated through the printer console.  The one with firmware 1126AR (on a different network than the other) will connect to web services but says that no firmware updates are available.  i'm running the updates via USB cable and have even uninstalled and reinstalled the software to set the 1110AR up for USB with the wireless radio turned off.  I had a copy of the older 1126AR firmware and ran it via USB.  The 1110AR printer said status Not applicable and the 1126AR printer said up-to-date.  I'm about at wit's end.

Hi Everyone,

I have tested this firmware, and does appear to have an issue with placing the check mark into the box. I am escalating this to the engineers, and will update this post as soon as I have any additional information. Thank you for reporting this issue.

[Talon4x4]

Thanks PCWizard for doing that!!!  Hopefully we will be able to get some sort of resolution.

Today I decided to extract the firmware file (OJ6500_E710n-z_R1206A.exe) and see if it would give me any clues.  Here is a list of files I found inside.

chianti_pp_usr_hf_CIP1FN1206AR_update_from_1023B_signed.ful  (the actual firmware file I would guess)

EnterpriseDU.exe (the program that searches for the pritner)

EnterpriseDU.ini (setting for above program)

EnterpriseDU.log (a log that is written after you run the .exe)
EnterpriseDUUI.dll (library for above .exe)

printer.ini (another setting file with no info)

Here is the inside of EnterpriseDU.ini.   I'm not a programmer so I'm not positive but I would think the ability to not select the printer has something to do with this .ini.  Hopefully someone with more knowledge on this will jump in.

Interesting. The HP developer commented-out the signature for the CIP1FN1110AR firmware in the EnterpriseDU.ini file. See the semi-colon before the 4=...

They probably meant to comment-out the following signature for the CIP1FN1126AR  firmware, as that is the version being distributed with this update.

If I get a chance later today, I'll remove the semi-colon from before the 4=... and see if I can update via the USB and report back my results. If someone beats me to this, report your findings too.

Thanks,

Gyle

Ohhh man thats my fault.  I put that there!!!  I was looking at their comment ";Download ID is used to filter devices" thinking maybe by filtered they meant any device listed was filtered out and shouldn't get the update.  So, I put the semi-colon in to see if it would allow my device, which it didn't, but forgot to take that out when I posted up the info.

[gyle_iverson]

No worries.

I just upgraded my printer by hacking the EnterpriseDU.ini file.

Change the VerifyDownloadID value from 1 to 0 and then run the EnterpriseDU.exe program. I had to click Refresh twice before my printer was found. That could be because I was connected over the wired network instead of USB perhaps.

Anyway, after that, the firmware installed in a few minutes and finally printed a Status Report showing the CIP1FN1206AR firmware version.

Hopefully HP will figure out the right way soon so other don't need to hack.
