HP M4345

[TommyH]

Got an HP M4345, when end user runs a large job through the adf to scan to network or email (job is duplexed). After a while the machine will say there is a jam in the ADF. When we look there is no jam. No leftover corners, stuck flags, etc. Paper has fully cleared the ADF but after you open and close the adf top the error will not go away. At this point the machine has to be powered off and powered back on. Problem with this is that the job they were doing is now lost and has to start all over. If you than print an event log it shows an error of 30.01.25 device error.

Whats been done. I have checked and replaced the rollers, cleaned all of the feed rollers, checked for obstructions, checked sensor flags for sticking. Came across nothing. Upgraded the firmware to most recent and still having this problem.

Per manual says upgrade firmware or replace the unit. I saw for another machine people where saying it was the HDD going out. Was thinking of doing a disk int next before replacing the unit. Any other suggestions???? Client is doing alot of scanning this time of year and having to start a job over and over is not good.

HP has had major firmware upgrades to this unit. Here is the link.
HP LaserJet M4345 Multifunction Printer series- Download drivers and software - HP Business Support Center

Please read all attached txt files before performing the upgrade. The txt file should say if your problem is addressed by the upgrade.
If I remember this upgrade also takes care of a security problem on the Jetdirect firmware.

Thanks, I have already done the firmware upgrade. It did say in there files that it is suppose to take care of the 30.01.25 error codes. Says its b/c the jam was too quickly that this is caused. But no luck with the firmware upgrade on this device. Still is doing it, if there is truely no jam you open/close the adf cover and error does not go away till a reboot. If there is a jam half the times once it clears the message goes away and the other half it doesn't. Thinking one of the sensors maybe going bad as none of the flags are getting stuck. Whats really bad is you have to buy the unit as a hole and not just parts.

I am sorry to say the whole unit scanner is next. Call partsnow 1-800-886-6688 you will need to setup an account. Then talk to their tech support. These are real techs not like HP menu readers.
They can probably get you a better price and I know the warranty is better than HP. I have been using them for 7 yrs.

Been using them as well so will look into that. I was afraid that was the only option next. However, I got out there today and it was still the same old firmware (had their IT update it on Friday morning). We tried to send the RFU 2 more times today and its not taking the firmware upgrade through FTP. After the first attempt today, we downloaded the upgrade again and still no luck. It sends it, the machine reboots and goes to ready but still has older version.

Looks like I have to look at this now some more and figure out whats going on with that.

Instead of FTP put the printers IP address into a internet browsers address line to access the web interface of the printer.
You can update the firmware from there. I found this works better than ftp. I that does not work go to parallel.

OK thanks. Going back out tomorrow so will try these. Have you had any problems with clicking/grinding noises coming from the back area of the ADF? I have alot of these units out there and the one in my office is making a bad clicking noise from the rear area. I haven't had the covers off yet to see whats going on with that. I only have 2k on my adf unit, I am afraid that with the 15 or so of these I service in the field this could be an issue. Going to have to start keeping several for parts after I figure out what this noise is and if it becomes a common problem.

[Rob Sandberg]

You have me beat I have 1.

Remove the fuser on the one that is clicking and check for grey or black dust in the cavaity under the gear that drives the fuser.
If so you need the guide plate upgrade.

Where abouts in the web interface can you update the firmware? I logged into the one here at the office through the ip in interent explorer. Didn't see anywhere to do it from the web interface. I know I can do ftp://xxx.xxx.xx.xx and it brings me to the ftp that way, but that is also like doing through the command prompt I would think.

As far as the grinding its not in the fuser. Have dealt with those gears on the 4300's and now the 3035. Haven't ran across it yet on the 4345 knock on wood. Its almost the same noise but def coming from the adf. As it does it when scanning only as well. When I get the time going to pull off the rear cover to watch the drive gears while it runs to see if I can notice anything. Hope to get that before end of week.

[Rob Sandberg]

As for the Web interface I will have to look. It has been a while since I have done one.
It was just a thought on the fuser drive gear.

Oh I know, was first thought I had as well. Thanks for your help though. Still working on the firmware update. I might try to do the easy install from one of the end users computers that connected to the printer. Or via usb on mine computer as I have drivers. I have heard though the usb does not always go so well.

[Rob Sandberg]

Use a cross over cable from a laptop to the network port on the printer.
This isolates the process from outside interferance.
The web interface will still work.
The more I think about it the upper unit will need replaced.
The customer may not like the cost.
