Xerox d95 memory issue and firmware update

we have 2 xerox d95 printers with build in controller.  if the printer prints a lot of jobs (i.e. 4000+) without a power cycle then eventually the printer would stop working.  one of the error is - it would output a page stating

 

ERROR: limitcheck

OFFENDING COMMAND: xshow

STACK:

[...]

 

another problem

this job requires more memory than is available in this printer .....

 

once the problem started then all subsequent output are blank pages.  I startted to try to resolve this issue, i found the printers don't have latest firmware.  our firmware is

 
SystemVersion 25.0.41
Controller+PS ROMVersion 1.201.1
IOT ROMVersion 83.25.0
HCF ROMVersion 4.6.0
Finisher D ROMVersion 5.15.0
IIT ROMVersion 9.8.0
ADF ROMVersion 13.10.0
SJFIVersion 3.0.18
SSMIVersion 1.16.0

 

we want to update the firmware, but since our process rely on OMR that needs to be at a specific region of all output for the inserter, we also wnat to rollback firmware update if something goes wrong.  so, it is possible to rollback?  if so, where can i get the older firmware?  Thanks,

 

Bryan

Re: Xerox d95 memory issue and firmware update

You can upgrade easily, but downgrading requires special software to do, which I believe to be proprietary to Xerox. (Tech call needed)

 

Xerox only ever has one firmware per device posted, which is the latest General Release.

 

There is also always a link that can be obtained easily enough to the latest spar (Call and ask for it)

 

Any firmware in between might as well not exist , it is near impossible to get if you don't have it already as Xerox does not want people using "known bad" configurations. If you need a specific version, you need to archive it yourself.

 

Assuming you are printing via an LPR port and not RAW, the following should resolve the issue you are seeing.

 

Machine Status > Tools > System Settings > Print Service Settings > Allocate Memory > Recieveing Buffer - LPD > Spool to HDD

Re: Xerox d95 memory issue and firmware update

the printers use "Raw" mode, which don't have spool to HDD option. I'm still in the process of evaluating ways to resolve this issue 1. update the firmware hoping the issue will be gone, or 2. change to LPR mode, and turn on spool to hdd. Bryan

Re: Xerox d95 memory issue and firmware update

Firmware is unlikely to help a memory issue like this, LPR is the better method and is just a box to check in the port to enable.

Set it and forget it, there are also no downsides to LPR, it is better in every way, just don't enable LPR byte counting (Assuming Standard TCP/IP port converted to LPR and not true LPR)

Re: Xerox d95 memory issue and firmware update

Hi Joe, thanks for your quick response. I agree with you - change to LPR first; however, my trouble is these are production printers that are printing most of the time in working hours, i have little time to arrange some testing. I'll post back once the issue is resolved. Bryan

Re: Xerox d95 memory issue and firmware update

just a note

 

its possible to download the machine without a tech call needed

 

you need to perform this with a USB stick

 

make a foldder in the root called DWLD , place the firmware in it

 

power down the machine, press AND hold 4 and energy button, power on machine, with usb stick in, release the 2 buttons when the machine is in download mode

 

wait a few mins , done

 

even with a downgrade all settings are still applied :)

Re: Xerox d95 memory issue and firmware update

We invloved Xerox to perform a firmware upgrade since they claimed they can perform a downgrade if unforseen problem happened.  After they upgrade the memory problem occurred once we have hight enough volumn in a day.  since the upgrade doesn't make the printer any worse, we decide to keep the firmware.

 

Afterward I proceeded to change printer settings to "LPD spool to HDD" and change print queue to use LPR instead of Raw.  We just had the same memory problem again, so none of solution works.
