Couple problems with C652's

[sparkin19]

When printing multiple print jobs, jobs will back up in the machines queue causing the machine to print slow or lock up.

Slow printing or locking up when printing multiple print jobs.


When the machine is printing multiple print jobs, the machine will cycle between print jobs. This causes the machine to slow down and if the queue fills up enough, it could lock up the machine.

The reason the machine cycles between print jobs is because the machine is checking which printer language (PCL or PS) the next print job is using. To stop this from happening, you have to tell the machine which PDL to use. To accomplish this, please perform the following:

1. Utility
2. User Settings
3. Printer Settings
4. Basic Settings
5. PDL Settings
6. Choose PS or PCL, depending on what driver is being used.

Note: All computers that are printing to this machine will have to use the same printer language as what the machine has defaulted to (PCL or PS).

Thanks, but I already tried this and it did not solve the problem...

any updates? this was an interesting one!!

any updates? this was an interesting one!!

Update is that I'm still in the process of trying to return these units... Still getting the lock-ups multiple times per day... They've tried everything (even physically removing the fax boards from the device) and nothing has changed....

Sad part is that all the replacement units I've looked at (Xerox, LexMark, Ricoh, etc.) have worse output quality and are slower... But at least (I hope) they wont' lock-up three or four times a day...

yea.i agree

that is a shame..i personally like the look of the konica machine and prints..i like the availability of their parts and they usually run at some of the lower cost per page retailed out.. I hope someone can help you as i would love to hear what solves this.has it ever locked up just doing a copy job? is it always when someone send something to the network?maybe take one off the network..turn off the networrk card and run it and see what happens?

Yes, it is a shame and I agree - I like the look, functionality, cost per page, output quality, etc. I really feel like I'm "downgrading" in moving to another machine...

And nobody would love to know what the actual problem is/was than more than myself... But it's been four and a half months and we're not one inch closer to a solution...

Unplugging it from the network isn't an option as we need to be able to print... The techs have asked the same but I mean, how far can you take it? I mean, I'm sure if I unplug it from the wall or leave it powered off all the time it would "perform" without any problems... But what good does that do. How would you like it if your car was stalling all the time and your mechanic told you to leave it parked in the garage and never drive it and see if it has any problems?

Still would like recommendations on a replacment unit, but it seems nobody likes ANY copier/printer...

[mailderrick]

ok

te reason i suggested that because in many differnt copiers,laser printers etc. when a network card has a problem it can at times cause the machine to lock up. I would want you to leave it plugged in and turned on and use it as a copier if possible. Just for however long it would usually take it to lock up. I am not sure if konica has updated firmware for network cards but it is worth taking a look at . someone on this forum should know if they ever release and update those.....also..try maybe to go through a different port on the machine..buy an external jetdirect and see if that does the trick but find a way to disable the network port to see if you can narrow it down to that

First thing I was thinking was you mentioned the lock up first thing in the morning; make sure your fierys are getting power directly from wall. When machine returns from auto power or sleep mode to normal operation it can lock out the controller and lock up machine waiting for it to boot. I have seen this cause many issues. Also turn off split line detection the current firmware is too sensitive, WE should see it corrected in later firmware!

[BigDaveE]

1) I don't think I can use a JetDirect box without losing almost all functionality (user authentication, stapling, etc.)

2) These don't have fiery controllers.... Just the basic/standard controller. They don't lock-up first thing in the morning... It's randomly throughout the day (but always during business hours).

I'm not sure if you've answered this or not, but are these networked through a server or our they locally installed on the pcs?
And has the tech been able to recreate the issue? I hate to see this problem go unresolved.........
I would make the branch bring you in a loaner for one of the machines and see if they can recreate the issue with a crossover cable and a laptop.....
I hope they get this resolved........BigDaveE

[BigDaveE]

They've offered to swap in a loaner but I don't see what good it would do. If it was only one of the machines that was having a problem I could see the benefit... But both are doing the same thing... So in my opinion there'a 99.9% probability that any other C652 will do the same thing (once it's onsite here).

And plugging in a notebook with a crossover cable isn't effective either... We're sending hundreds of jobs a day to it from who knows how many applications and sources. They can't simulate our environment on a notebook...
It goes back to the other suggestion of unplugging it from the network... I'm sure it'll work if you completely remove it from the environment (which is what disconnecting it does). Besides, we need these devices to do business - we can't just deactivate or disable them for a significant amount of time...

I had a similar problem to this on a C550 a few months ago. It was a networked and heavily used machine with print jobs just like yours.

Turned out to be the "Low Power Mode" and "Sleep Mode". It was set to the default which I think is 15 mins.
If the machine received a print job at the same split second it tried to enter "Low Power Mode", it hung up.

Sounds like it could be the same issue with you. No print jobs overnight = no hang ups, the machine can enter "Low Power Mode" unmolested which maybe why it only happens during working hours.

Try altering the settings to the maximum which is 240 mins I think?. Both can be found in Administrator settings in Utility/Counter.

Hope this helps.

I wish it was that easy... It does not go into sleep mode during the day... I have it set for low power mode after 90 minutes and I STRONGLY doubt we ever go an hour and a half without a print job... Sleep mode is set to 240 minutes...

"How would you like it if your car was stalling all the time and your mechanic told you to leave it parked in the garage and never drive it and see if it has any problems?"

Nice ;-)

[BIG PAPA]

Wow, This post is generating some excitment isnt it. First thought is that you are already admitting that it is something specific to YOUR environmenet, but you are not letting the techs run through the process. Second the comment of who knows how many applications and sources??? Your IT dept should pretty much know this. Also when it "locks up" Is the machine completly unresponsive, or does it just quit outputting? Can it be accessed via PSWC? What is in the print que at the time? You are quick to ask for advice, but then quicker to shoot everyone down, without giving a hole lot of details.
