Re: HP Printer Assistant Script Error - Officejet 4620

Hi,

I still have the scripting errors after applying several solutions found on this forum to an XP SP3 system. (NB the first script error is as in the original post, the second, see the end of this post, appears in the new "Printer Assistant" window that opens in front of the first error dialog. Dismissing the second error dialog twice results in "String not found" at the search icon and in place of "Dynamic..."). Is there any chance that the .json script problem across multiple OS and multiple HP products results from JRE 7 replacing JRE6 on many machines?

A. Unistall and reinstall of downloaded OJ4620_1315.exe

-- result: script errors not corrected

B. Run from the CD (where X: is the CD) "X:\utils\x86\RemovePreinstalledDrivers.exe" and replace "C:\DOCUME~1\username\LOCALS~1\Temp\7zS....\OJ4620x86.msi" with "OJ4620x86.msi" from the CD

-- result: no window, dialog or alert. TaskManager shows that the process started, terminates after a few seconds.

C. Repeat A. to get back to square one

D. Backup of registry and application of SCLiteFix_299026.exe fix from

http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&dlc=en&docname=c03640384

-- result: script errors not corrected

E. Restore registry and apply manual fix from D.

-- result: script errors not corrected

F. Apply steps 1-10 from the quoted solution

Hi,

 

Do the following,

 

1. Go to “C:\Program Files\HP\<Printer Model>\Bin\UDC_Files” folder
2. Look for “localize_1033.json” file and rename it to “localize_1033.json.old”
3. Look for “tasks.json” file and rename it to “tasks.json.old”
4. Go to Driver CD or Install Location (whichever is the latest)
5. Look for Full_x86.cab or Full_x64.cab (OS Dependent – {64bit OS select Full_x64} {32bit OS select Full_x86 })
6. Open the CAB File
7. Look for “UDC_Files_localize_1033” and “UDC_Files_tasks”
8. Extract the file to “C:\Program Files\HP\<Printer Model>\Bin\UDC_Files”
9. Rename the “UDC_Files_localize_1033” to “localize_1033.json”
10. Rename the “UDC_Files_tasks” to “tasks.json”
11. Go to “C:\ProgramData\HP\<Printer Model>”
12. Look for “HPUDC” folder and rename it to “HPUDC_1”
13. Close all Windows
14. Make sure the printer is Online (Make sure you are able to Open the EWS Page or able to Print and Scan)
15. Open HP Printer Assistant and check

followed by  the XP equivalent of steps 11 and 12, going to "C:\Documents and Settings\All Users\Application Data\HP\HP Officejet 4620 series\HPUDC", renaming it to HPUDC_1, and finally followed by steps 13-15.

-- result: script errors not corrected, new HPUDC directory created at the above location as expected.
