C280 intermittently locking up

[huntergazz]

Hi Guys,

I have had this problem quite a few times on the 220, 280 and 360. 9 times out of 10 I have resolved by backing up all the settings, performing a full format of the hdd and then a logical format. Reload the settings that you exported and bobs you uncle! I have only had to replace 2 hdd's out of the 150 machines I look after in the field.

Looks like he's got a fix for ya right there. I was kinda thinking HDD, but... with it not running and locking up I would have probably said Ram.

Logical steps for this are:

Firmware (which you've done, always check for 'special firmware' relating to the issue, though)
Memory/Connector re-seating - try a pencil eraser on the RAM contacts, fixed a few for me
HDD format/replacement - as others suggested
NVRAM reset
followed by Board replacement

Be sure to let everyone know what did the job for you! Good luck.

I performed the physical and logical formatting of the HDD, but machine is still freezing up. I have not yet done the NVRAM. I guess that will be next. I'm still wondering if it's a particular print job doing this??????????????????????????????? But I haven't seen a pattern with this yet.

Make sure all of your users are using the correct print driver.

I have had certain PDF documents lock up a client's C353 before. Typically you can remedy this with a PS driver, but in some cases I have seen old out of date versions of acrobat cause the machine to lock up completely. Updated acrobat (in this case, from version 5 > version 9 at the time) and the problem went away.

Just an update. I installed a brand new 28C6 just to eliminate a lot of guessing in the current machine and it also froze up. I pulled the new machine back out and tried and updated driver for the current machine and it continued to lock up. I'm going to try assigning the machine a different ip address and see if this makes any difference.

U have on KM site for technician TAD for this problem,read it, it will help

If you installed a new machine that is also locking up, there is likely a driver issue, or a network device/service that is causing the machine to crash. Isolate it from the current network and you will probably see that the problem does not persist. I don't know if your contract with your customer extends over their network, but we typically charge good money to diagnose the problem if it doesn't originate from the copier itself.

I recommend changing the IP address of the copier first and foremost, and doing a clean setup on the PCs/Server to eliminate the possibility that someone has a bad job sending to it, or an old driver that you missed.

Thanks for the advice guys. Boanda, I do not have access to this TAD you are talking about. We sell the KM machines through NEC and do not have access to everything they release. Can you provide this information to me? Thanks.

Just an update... I ended up changing the IP address of the machine and I have had no more instances of the machine locking up. This machine has been using the same IP address since install. Unfortunately one of the easiest things I could have done to solve this problem was the last thing I tried. It just didn't make since that an IP address that the machine has been using without issue would all of the sudden start causing problems. Thanks for all the helpful posts.

Re: C280 intermittently locking up

Finally found this thread. I guess I did think of the solution without prompting.

My first attempt was to change the network speed setting from "Any" to "10MBs Full Duplex", which got the prints through, but slowed down the web page interactions so that the new settings weren't being stored.

The solution was "100MBs Full Duplex". =^..^=

Re: C280 intermittently locking up

just a dumb question here, did you check/change network cable and the network jack pin? in the pass I see copier/printer have very slow respond on print job, some work fine after change cable some was network jack pin bend up

and I also fixed some c280 and bh361 with bad hdd, that cost the machine lock up, solution was drop in new hdd (to test is hdd error or not, just turn off hdd in service mode)
and some user using hp driver and locks up the machine as well, but that was on bh223

... with and without the surge suppressor connection, three different cables, two different network jacks. =^..^=

Re: C280 intermittently locking up

All but a few replies ignored the "theres always a print in the queue", IP conflicts usually have abort codes or even a plain english warning on the machine. I was going to assume you're problem was with a corrupt file re-queing or a Windows 7 issue, which is very buggy with Konicas.

Utility aUser Settings aPrinter Settings aBasic Settings aPDL Settings athen choose PostScript or PCL (depending on what driver is being used) try this mybe will help?
